Furnace Not Blowing Hot Air? Here’s What Summerville Homeowners Should Check
Furnace Not Blowing Hot Air? Here’s What Summerville Homeowners Should Check When your furnace runs but doesn’t blow hot air, the most common causes are thermostat issues, a clogged air filter, pilot light or ignitor failure, or a tripped safety switch. Start by checking your thermostat settings and replacing your air filter—these simple fixes resolve many heating problems without a service call. If those don’t work, the issue likely involves your ignition system, gas supply, blower motor, or heat exchanger, which require professional diagnosis. For Summerville homeowners, understanding what’s safe to troubleshoot yourself versus when to call for professional heating repair can save time, money, and frustration on cold Lowcountry nights. When Your Heater Runs But the Air Stays Cold Few things are more frustrating than hearing your heating system running while cold air blows from your vents. The system sounds like it’s working. The thermostat says it should be heating. But your house keeps getting colder. This disconnect between “running” and “heating” is actually helpful for diagnosis. It tells you the electrical components are functioning—the thermostat is communicating, the blower motor is operating. The problem lies somewhere in the heating process itself. Before you call for service, there are several things you can safely check yourself. Some fixes take less than five minutes. Others require professional attention. This guide helps you identify which situation you’re facing. Start Here: The Simple Fixes Before assuming the worst, check these common culprits that homeowners can address themselves: Check Your Thermostat Settings It sounds obvious, but thermostat issues cause a surprising number of “no heat” calls. Verify: Mode setting: Is the thermostat set to “Heat” rather than “Cool” or “Off”? In homes with heat pumps, an accidental switch to cooling mode means the system runs but produces cold air. Fan setting: If the fan is set to “On” rather than “Auto,” the blower runs continuously—even when the heating cycle isn’t active. This circulates unheated air between heating cycles, making it feel like the system isn’t working. Temperature setting: Is the set temperature actually higher than the current room temperature? The system won’t call for heat if it thinks the target temperature is already reached. Battery status: Many thermostats use batteries. Low batteries can cause erratic behavior or prevent the thermostat from communicating with your system. Replace batteries if your thermostat display is dim or blank. Programming check: If you have a programmable or smart thermostat, verify the schedule. Someone may have adjusted settings, or a software update may have reset your preferences. Replace Your Air Filter A clogged air filter is the single most common cause of heating problems—and the easiest to fix. When your filter is clogged: Airflow becomes restricted The system overheats trying to push air through Safety switches trip to prevent damage The furnace shuts down the heating cycle while the blower continues running How to check: Locate your filter (usually in the return air vent or at the furnace itself). Remove it and hold it up to light. If you can’t see light through it, it’s too dirty. The fix: Replace the filter with a new one of the same size. For most homes, filters should be replaced every one to three months—more frequently if you have pets or allergies. Important: If your system shut down due to overheating, it may need a few minutes to reset after you replace the filter. Turn the system off, wait five minutes, then turn it back on. Check Your Circuit Breakers Heating systems typically have multiple electrical connections: A breaker for the air handler/blower A separate breaker for the furnace or heat pump outdoor unit Sometimes a dedicated breaker for the ignition system If one breaker trips while others remain on, your blower might run while the heating components don’t. Check your electrical panel for any tripped breakers related to your HVAC system. The fix: Reset any tripped breakers by switching them fully off, then back on. If a breaker trips again immediately, don’t keep resetting it—this indicates an electrical problem requiring professional attention. Inspect Your Vents and Registers Blocked or closed vents can create pressure imbalances that affect system performance: Make sure all supply vents are open and unobstructed Check that return vents aren’t blocked by furniture or rugs Verify that no one has closed vents in unused rooms (this can cause system-wide problems) While blocked vents usually cause uneven heating rather than complete heating failure, checking them takes only a minute and rules out an easy fix. Furnace-Specific Troubleshooting If the simple fixes didn’t solve your problem and you have a gas or electric furnace, these issues may be the cause: Pilot Light Problems (Older Gas Furnaces) If your furnace is more than 15–20 years old, it may use a standing pilot light—a small flame that burns continuously and ignites the main burners when heat is needed. Signs of pilot light issues: No heat at all from the furnace You can hear the furnace trying to start but it doesn’t ignite Visible pilot light area shows no flame What you can check: Many furnaces have a small window that lets you see the pilot light. If it’s out, you may be able to relight it following the instructions on the furnace’s label. Caution: If you smell gas, don’t attempt to relight the pilot. Leave your home immediately and call your gas company. Gas leaks are emergencies. When to call a professional: If the pilot won’t stay lit after relighting, the thermocouple (a safety device that detects the pilot flame) likely needs replacement. This is a professional repair. Ignitor Failure (Modern Furnaces) Most furnaces manufactured in the last 20 years use electronic ignition rather than a standing pilot light. Common types include: Hot surface ignitors: A ceramic element that glows red-hot to ignite gas Intermittent pilot: An electronic spark that lights a small pilot, which then ignites the main burners Signs of ignitor failure: Furnace attempts to start (you hear clicking or see the inducer fan run) but doesn’t ignite System tries multiple times then shuts down Error codes on the furnace control board (if equipped)
Duct Cleaning After Home Renovation: Why It’s Essential for Your Health and HVAC System
Duct Cleaning After Home Renovation: Why It’s Essential for Your Health and HVAC System Duct cleaning after a home renovation is essential—not optional. Construction projects generate massive amounts of dust, drywall particles, sawdust, and debris that infiltrate your HVAC system regardless of protective measures. This material settles throughout your ductwork and recirculates every time your system runs, degrading indoor air quality and straining your HVAC equipment. Post-renovation duct cleaning removes construction contaminants before they cause respiratory irritation, trigger allergies, or damage your heating and cooling system. For Summerville homeowners who’ve completed any significant remodeling project, scheduling duct cleaning immediately after construction ends protects both your family’s health and your HVAC investment. The Hidden Cost of Home Renovations You’ve survived weeks or months of construction chaos. The contractors are gone, the final punch list is complete, and your newly renovated space looks beautiful. But there’s something you can’t see: your ductwork is full of construction debris. Even the most careful contractors can’t prevent fine particles from becoming airborne during renovation work. Cutting, sanding, drilling, and demolition all generate dust that travels throughout your home—including into your HVAC system. Once there, it doesn’t just disappear. It waits for your system to turn on, then distributes throughout every room in your house. That “new construction smell” everyone talks about? Part of it is construction dust circulating through your air. What Renovation Projects Leave Behind Different types of projects generate different contaminants. Here’s what accumulates in your ducts based on common renovation work: Drywall Installation and Repair Drywall work is one of the worst offenders for duct contamination. The process generates: Drywall dust: Extremely fine particles that become airborne easily and travel far from the work area Joint compound dust: Created during sanding of seams and patches Gypsum particles: The calcium sulfate that makes up drywall’s core Drywall dust is particularly problematic because of its fine particle size. It passes through standard air filters, settles deep in ductwork, and can take weeks to fully clear from indoor air without intervention. Flooring Projects Flooring installation and refinishing introduce various contaminants: Flooring Type Contaminants Generated Hardwood sanding/refinishing Wood dust, finish fumes, polyurethane VOCs Tile installation Thinset dust, grout particles, tile cutting debris Carpet removal Old carpet fibers, dust, adhesive residue, trapped allergens Laminate/vinyl installation Cutting dust, adhesive fumes Hardwood floor sanding is especially concerning. The fine wood dust travels throughout the home, and the finishing products release volatile organic compounds (VOCs) that can linger for weeks. Kitchen and Bathroom Remodels These comprehensive projects combine multiple contamination sources: Demolition debris from removing old fixtures, cabinets, and surfaces Drywall dust from wall modifications Tile and grout dust from backsplash or floor work Plumbing modifications that may disturb existing dust in wall cavities Paint fumes and primer off-gassing Room Additions and Major Structural Work Large-scale projects introduce the full spectrum of construction contaminants: Concrete and masite dust from foundation work Framing sawdust from lumber cutting Insulation fibers (fiberglass or cellulose) Roofing material particles Exterior debris tracked through the home Painting Projects Even “simple” painting projects affect air quality: Paint fumes and VOCs during application Sanding dust from surface preparation Primer off-gassing Caulk and sealant fumes Why Protective Measures Aren’t Enough Good contractors take precautions during renovation work. They may: Seal off work areas with plastic sheeting Cover supply and return vents Use negative air pressure machines Clean up debris daily These measures help—but they don’t eliminate the problem. The Limitations of Containment Plastic barriers leak. Even carefully taped plastic sheeting has gaps at seams, floors, and ceilings. Fine dust particles find their way through. Vent covers aren’t airtight. Covering vents with plastic or tape reduces debris entry but doesn’t stop it completely. Pressure differentials in your home still draw air—and particles—toward return vents. Dust travels through unexpected paths. Construction dust migrates through electrical outlets, gaps around pipes, and other penetrations in walls and ceilings. It doesn’t respect containment barriers. HVAC systems run during construction. Unless you completely shut down your heating and cooling for the duration of the project (impractical for most renovations), your system circulates air—and whatever’s in it. The Cumulative Effect A single day of drywall sanding can introduce pounds of fine dust into your home’s air. Multiply that by weeks or months of construction activity, and the accumulation in your ductwork becomes significant. Even if 90% of construction debris is contained or cleaned up, the remaining 10% ends up somewhere—and much of it ends up in your ducts. Health Concerns from Post-Renovation Air Quality Construction dust isn’t just unpleasant—it can affect your health. Respiratory Irritation Fine particles from drywall, wood, and other construction materials irritate the respiratory system. Symptoms include: Coughing and throat irritation Nasal congestion and runny nose Shortness of breath Chest tightness Aggravated asthma symptoms These symptoms often persist for weeks after renovation completion if ductwork isn’t cleaned. Silica Exposure Many construction materials contain crystalline silica, including: Concrete and morite Drywall joint compound Tile and grout Some paints and coatings Inhaling silica dust can cause serious respiratory issues. While brief exposure during home renovation isn’t equivalent to occupational exposure, minimizing inhalation is prudent—especially for children, elderly family members, or anyone with respiratory conditions. VOC Exposure Volatile organic compounds off-gas from: Paints and stains Adhesives and sealants Flooring materials Cabinetry and countertops (especially engineered products) VOCs can cause headaches, dizziness, eye and throat irritation, and in some cases, more serious health effects. While duct cleaning doesn’t remove VOCs directly, removing dust that has absorbed these compounds reduces one exposure pathway. Allergen Redistribution Renovation work disturbs settled dust throughout your home—including allergens that had been dormant. Old carpet removal, wall demolition, and attic work can release years of accumulated: Dust mites and their waste Pet dander from previous occupants Pollen trapped in building materials Other allergenic particles If you or family members have allergies, post-renovation air quality can trigger significant symptoms until these redistributed allergens are removed. Impact on Your HVAC System Construction debris doesn’t just affect air quality—it threatens your HVAC equipment. Clogged Air Filters Your air filter is the first
Best Time to Clean Ducts in the Lowcountry: A Seasonal Guide for Summerville Homeowners
Best Time to Clean Ducts in the Lowcountry: A Seasonal Guide for Summerville Homeowners The best time to clean air ducts in the Lowcountry is late winter (February–March) before spring pollen season or early fall (September–October) before you seal up the house for cooler weather. These windows let you remove accumulated contaminants before your HVAC system runs heavily and before seasonal allergens peak. However, the “right” time also depends on your specific situation—after renovations, when moving into a new home, or whenever you notice warning signs like excessive dust or musty odors. For most Summerville homes without specific concerns, scheduling duct cleaning every three to five years during these seasonal windows provides optimal results. Why Timing Matters for Duct Cleaning Duct cleaning isn’t an emergency service for most homeowners. Unlike a broken air conditioner in July, you have flexibility in when to schedule it. That flexibility is actually an advantage—it lets you choose timing that maximizes the benefits. The Lowcountry’s climate creates specific considerations that don’t apply everywhere. Our long, humid summers, intense pollen seasons, and mild winters all influence when duct cleaning delivers the most value. Strategic timing helps you: Remove allergens before peak allergy seasons Start heavy HVAC usage with a clean system Avoid scheduling conflicts during busy seasons Potentially save money during slower periods The Lowcountry Climate Factor Summerville’s subtropical climate affects your ductwork differently than homes in drier or colder regions. Humidity and Moisture Our average humidity hovers between 70% and 90% for much of the year. This moisture can: Cause dust and debris to clump and adhere to duct surfaces Create conditions where biological growth may occur Make accumulated contaminants harder to remove the longer they sit Cleaning ducts before the most humid months (June–August) removes debris before moisture makes it more stubborn. Extended Cooling Season Lowcountry homeowners run air conditioning from April through October—sometimes longer. That’s six to seven months of continuous HVAC operation, circulating air through your ducts daily. Compare that to northern climates where AC might run three to four months. More runtime means more opportunities for dust, pollen, and other particles to accumulate. It also means your system works harder, making efficiency gains from clean ducts more impactful. Intense Pollen Seasons Summerville experiences two significant pollen seasons: Season Peak Months Primary Culprits Spring March–May Oak, pine, birch, grass Fall August–October Ragweed, goldenrod, grass Pollen enters your home and gets pulled into your HVAC system, where it settles in ductwork. Cleaning before these seasons removes last year’s accumulated pollen and reduces your baseline allergen exposure. Mild Winters Our relatively mild winters mean we use heating less intensively than northern regions. However, when temperatures drop, homes get sealed up tight—windows closed, doors shut. Any contaminants in your ducts recirculate continuously with no fresh air dilution. Cleaning ducts before winter ensures you’re not trapped inside with a season’s worth of accumulated dust and allergens. Best Seasonal Windows for Duct Cleaning Based on Lowcountry climate patterns, two windows stand out as optimal: Late Winter: February–March Why it works: Before spring pollen: Oak and pine pollen explode in March and April. Cleaning in February removes last year’s pollen before the new wave arrives. Before heavy AC usage: Your system has been relatively idle during winter. Clean it before it starts running 12+ hours daily. Slower season for HVAC companies: Easier scheduling and potentially better availability. Post-holiday timing: The busy holiday season is over, making it easier to schedule home services. Ideal for: Allergy sufferers preparing for spring Homeowners who want a fresh start for the cooling season Anyone who hasn’t had ducts cleaned in several years Early Fall: September–October Why it works: Before sealing up for winter: Remove summer’s accumulation before you close windows and rely entirely on recirculated air. After summer humidity: The worst humidity is behind you, and debris that accumulated during summer can be removed. Before fall allergens peak: Ragweed season runs August through November. Early fall cleaning reduces exposure during the back half. Before holiday guests: Get your home’s air quality in shape before hosting family and friends. Ideal for: Homeowners preparing for holiday gatherings Those who ran AC heavily all summer Allergy sufferers sensitive to fall allergens When to Clean Regardless of Season Some situations call for duct cleaning regardless of the calendar: After Home Renovations Construction projects generate enormous amounts of dust, drywall particles, sawdust, and debris. Even with protective measures, this material finds its way into ductwork. Clean ducts immediately after: Kitchen or bathroom remodels Room additions Drywall installation or repair Flooring replacement (especially sanding hardwood) Any project involving cutting, sanding, or demolition Don’t wait for the “optimal” season—renovation debris should be removed as soon as the project is complete. When Moving Into a New Home Whether your new home is newly constructed or previously owned, duct cleaning makes sense: New construction: Despite builders’ best efforts, construction debris accumulates in ductwork during the building process. Many new homes have never had their ducts cleaned. Previously owned homes: You inherit the previous occupants’ dust, pet dander, and whatever else accumulated during their tenure. Starting fresh with clean ducts eliminates that history. Schedule duct cleaning during the transition period—after closing but before or shortly after moving in. After Water Damage or Flooding If your home has experienced water intrusion—whether from flooding, roof leaks, or plumbing failures—your ductwork may have been affected. Important: If you suspect moisture has entered your duct system, have a certified professional assess for potential mold before scheduling standard duct cleaning. Mold remediation requires specialized expertise beyond duct cleaning. At Coastal Carolina Comfort, we don’t perform mold testing or remediation—if we observe potential concerns, we’ll recommend you consult a certified mold professional first. When Warning Signs Appear Don’t wait for the optimal season if you notice: Visible dust blowing from vents when the system runs Musty or stale odors when HVAC operates Unexplained increase in allergy or respiratory symptoms Excessive dust accumulation despite regular cleaning Visible debris or discoloration in or around vents Pest activity in or around your HVAC system These signs indicate your ducts need attention
Duct Cleaning Scams: How to Spot Them Before You Get Burned
Duct Cleaning Scams: How to Spot Them Before You Get Burned Duct cleaning scams typically start with an unbelievably low price—often $49 to $99 for “whole-house” cleaning—then escalate through high-pressure upselling, fake mold discoveries, or bait-and-switch tactics. Legitimate duct cleaning for a standard home costs $300–$500, reflecting the specialized equipment and time required. Red flags include unsolicited phone calls or door-to-door sales, quotes given without inspection, pressure to decide immediately, and technicians who “discover” urgent problems requiring expensive repairs. Protect yourself by verifying NADCA certification, checking Better Business Bureau ratings, getting written estimates, and never paying the full amount upfront. The $99 Duct Cleaning Trap You’ve seen the ads. Maybe a postcard in your mailbox, a Facebook ad, or a door-hanger on your front porch: “Whole-House Duct Cleaning – Only $99!” “Air Duct Special – $49 for Unlimited Vents!” It sounds like a great deal. Your ducts probably need cleaning, and who wouldn’t want to save a few hundred dollars? Here’s the problem: legitimate duct cleaning can’t be done for $99. The equipment alone—truck-mounted vacuums, HEPA filtration systems, rotary brushes—costs tens of thousands of dollars to purchase and maintain. A thorough cleaning of an average home takes two to four hours of skilled labor. At $99, the math doesn’t work. So how do these companies make money? By not delivering what they promise—and by pressuring you into services you don’t need. How Duct Cleaning Scams Work Scam operators follow predictable patterns. Understanding their tactics helps you recognize them before you become a victim. The Bait and Switch This is the most common scam. Here’s how it unfolds: The bait: You schedule service based on an advertised low price ($49–$99) The arrival: Technicians show up and begin a cursory inspection The switch: They inform you the advertised price covers only a few vents, or only “basic” cleaning. The “real” cleaning costs $300, $500, or more The pressure: They emphasize that since they’re already there, you might as well pay for the full service You’re now in an uncomfortable position. You’ve taken time off work, the technicians are in your home, and you feel obligated. Many people pay just to end the awkward situation. The Fake Mold Discovery This scam exploits homeowners’ legitimate concerns about mold: The setup: Technicians arrive for routine duct cleaning The “discovery”: They show you photos or video of “mold” in your ducts—often using images from other homes or misidentifying ordinary dust and debris The fear: They warn about health dangers, structural damage, or liability issues The upsell: They offer mold remediation services for $500–$2,000 or more Important context: Legitimate mold assessment requires certified professionals and laboratory testing. A duct cleaning technician cannot definitively identify mold species or determine whether remediation is necessary. If someone claims to find mold during a duct cleaning, get a second opinion from a certified mold assessment professional before authorizing any work. The Unnecessary Repair Scam Similar to the fake mold discovery, this scam manufactures problems: The inspection: Technicians examine your HVAC system The diagnosis: They claim your ducts are damaged, your system is failing, or components need immediate replacement The urgency: They warn that continued use is dangerous or will cause expensive damage The solution: They offer to fix the problem right now—for a significant fee Legitimate HVAC issues exist, but scammers exploit homeowners’ lack of technical knowledge. They may show you “damaged” components that are actually normal, or exaggerate minor issues into emergencies. The Incomplete Service Some scam operators simply don’t do the work: The arrival: Technicians show up with minimal equipment The “cleaning”: They vacuum visible dust from vent covers and perhaps the first few inches of ductwork The departure: They collect payment and leave within 30–45 minutes A thorough duct cleaning takes two to four hours and requires specialized equipment to reach deep into the duct system. If technicians are in and out quickly with basic tools, you haven’t received legitimate service. The Unsolicited Contact Scam Reputable companies don’t cold-call or go door-to-door offering duct cleaning: The contact: You receive an unsolicited phone call, or someone knocks on your door offering duct cleaning services The pitch: They claim to be “in the neighborhood,” offer a “one-time special,” or say they’re conducting “free inspections” The goal: Get inside your home to execute one of the scams above Legitimate HVAC companies have enough business from referrals, repeat customers, and people who seek them out. Aggressive cold-calling is a hallmark of scam operations. Red Flags: Warning Signs of a Duct Cleaning Scam Watch for these indicators that a company may not be legitimate: Pricing Red Flags Red Flag Why It’s Suspicious Prices under $150 for whole-house cleaning Below the cost of doing the job properly “Per vent” pricing that seems too low Often excludes the main duct runs No price given until technicians arrive Sets up bait-and-switch scenario Dramatically lower than competitors Legitimate companies have similar cost structures Special “today only” pricing Pressure tactic to prevent comparison shopping Communication Red Flags Red Flag Why It’s Suspicious Unsolicited phone calls or door-to-door sales Reputable companies don’t operate this way Quotes given without seeing your home Impossible to price accurately without inspection Pressure to schedule immediately Prevents you from researching the company Vague answers about methods or equipment May indicate lack of proper tools or training No physical address or only a P.O. box Difficult to hold accountable if problems arise On-Site Red Flags Red Flag Why It’s Suspicious Technicians arrive in unmarked vehicles Legitimate companies display their branding Minimal or consumer-grade equipment Professional cleaning requires specialized tools Service completed in under an hour Thorough cleaning takes 2–4 hours minimum “Discoveries” requiring immediate expensive repairs Classic upselling tactic Refusal to provide written documentation No accountability for work performed Demand for cash payment Avoids paper trail and consumer protections How to Protect Yourself Follow these steps to avoid duct cleaning scams and find legitimate service: Research Before You Need Service Don’t wait until you’re desperate. Research duct cleaning companies in advance so you have trusted options when you need them.

Dryer Vent Cleaning: Why It Matters for Summerville Homeowners
Dryer Vent Cleaning: Why It Matters for Summerville Homeowners Dryer vent cleaning prevents house fires, reduces energy costs, and extends your dryer’s lifespan. According to the U.S. Fire Administration, clothes dryers cause approximately 2,900 home fires each year, and lint buildup is the leading cause. When your dryer vent becomes clogged, hot air can’t escape properly—creating a fire hazard and forcing your dryer to work harder. Professional dryer vent cleaning removes accumulated lint from the entire exhaust system, not just the lint trap. For Summerville homeowners, annual cleaning is recommended, especially if your dryer takes longer than usual to dry clothes or feels excessively hot. The Hidden Danger in Your Laundry Room You clean the lint trap after every load. That’s enough, right? Unfortunately, no. The lint trap catches only about 75% of the lint your dryer produces. The rest travels into the dryer vent—the duct that carries hot, moist air from your dryer to the outside of your home. Over time, lint accumulates along the entire length of this vent, creating a serious fire hazard. Lint is highly flammable. Combine it with the heat your dryer generates, and you have the ingredients for a house fire. The U.S. Fire Administration reports that failure to clean dryer vents is the leading cause of dryer fires, ahead of mechanical failure and electrical issues. This isn’t a scare tactic—it’s physics. And it’s preventable. Warning Signs Your Dryer Vent Needs Cleaning Your dryer will tell you when the vent is clogged. Watch for these signs: Clothes Take Longer to Dry This is the most common symptom. If loads that used to dry in 45 minutes now take 60, 75, or even 90 minutes, restricted airflow is likely the cause. Your dryer can’t expel moist air efficiently, so clothes stay damp longer. Dryer Feels Excessively Hot Touch the top of your dryer during a cycle. Warm is normal. Hot enough to be uncomfortable? That’s a warning sign. When the vent is clogged, heat builds up inside the dryer instead of exhausting outside. Clothes Are Unusually Hot After a Cycle Similarly, if your clothes come out of the dryer extremely hot—almost too hot to handle—the dryer is working overtime to compensate for poor airflow. Burning Smell If you notice a burning odor when your dryer runs, stop using it immediately. This could indicate lint is overheating or has ignited. Unplug the dryer and have the vent inspected before using it again. Visible Lint Around the Outside Vent Check the exterior vent where your dryer exhausts. If you see lint accumulation around the opening or the flap doesn’t open properly when the dryer runs, the vent needs cleaning. Laundry Room Feels Humid or Hot A properly functioning dryer vent expels hot, moist air outside. If your laundry room feels humid or warmer than usual during drying cycles, that air may be backing up into your home. It’s Been More Than a Year Even without obvious symptoms, annual dryer vent cleaning is recommended. Lint accumulates gradually, and problems may not become apparent until the vent is significantly clogged. The Real Cost of a Clogged Dryer Vent Beyond the fire risk, a clogged dryer vent costs you money and shortens your appliance’s life. Higher Energy Bills When your dryer can’t exhaust air efficiently, it runs longer to dry each load. That extended run time adds up. According to Energy Star, a clogged dryer vent can increase energy consumption by 30% or more. For a household that does five loads per week, that’s a noticeable increase in your electric bill. Premature Dryer Failure Dryers aren’t designed to run for extended periods or operate at excessive temperatures. When a clogged vent forces your dryer to work harder, components wear out faster. The heating element, thermostat, and motor all suffer from the added strain. A dryer that should last 10–13 years may fail in seven or eight. Clothing Damage Excessive heat damages fabrics. Clothes dried in an overheating dryer wear out faster, shrink more, and fade sooner. Delicate items are especially vulnerable. Carbon Monoxide Risk (Gas Dryers) If you have a gas dryer, a clogged vent creates an additional hazard. Gas dryers produce carbon monoxide as a byproduct of combustion. Normally, this exhausts safely outside through the vent. When the vent is blocked, carbon monoxide can back up into your home—an invisible, odorless danger. Why the Lint Trap Isn’t Enough Many homeowners assume that cleaning the lint trap handles the lint problem. Here’s why it doesn’t: The Lint Trap’s Limitations The lint trap sits between the dryer drum and the exhaust system. It catches lint before it enters the vent—but not all of it. Fine lint particles pass through the screen, and lint that accumulates on the trap’s housing can bypass it entirely. The Journey Through the Vent Your dryer vent may run 10, 20, or even 30 feet from the dryer to the exterior wall. Along that path, lint settles on the duct walls, accumulates at bends and joints, and builds up near the exterior vent cap. None of this is addressed by cleaning the lint trap. Vent Configuration Matters Longer vents, vents with multiple turns, and vents that run vertically accumulate lint faster than short, straight runs. Many Summerville homes—especially two-story construction in neighborhoods like Cane Bay and Nexton—have dryers located far from exterior walls, requiring longer vent runs that need more frequent attention. What Professional Dryer Vent Cleaning Includes Professional cleaning addresses the entire exhaust system, not just the accessible parts. Here’s what to expect: Inspection Technicians inspect the vent system from both ends—at the dryer connection and at the exterior vent cap. They assess the vent’s length, configuration, and condition, and identify any damage or code violations. Lint Removal Using specialized rotating brushes and high-powered vacuums, technicians dislodge and extract lint from the entire length of the vent. This includes: The transition duct (flexible connector between dryer and wall) The rigid ductwork running through walls, floors, or ceilings Elbows and joints where lint accumulates The exterior
Duct Cleaning for Allergies: Does It Actually Help?
Duct Cleaning for Allergies: Does It Actually Help? Yes, duct cleaning can help reduce allergy symptoms by removing accumulated allergens—dust, dust mites, pet dander, and pollen—from your HVAC system. When these particles build up in ductwork, they recirculate through your home every time the system runs, triggering sneezing, congestion, itchy eyes, and respiratory discomfort. Professional duct cleaning eliminates allergens at the source, reducing your overall exposure. However, duct cleaning works best as part of a comprehensive approach that includes regular filter changes, humidity control, and source reduction. For Summerville allergy sufferers, addressing your ductwork can provide meaningful relief—especially before peak pollen seasons. Why Allergies Get Worse Indoors You’d think staying inside would give you a break from allergies. But for many Summerville residents, symptoms actually intensify at home. The culprit? Your HVAC system. Here’s what happens: allergens enter your home through open doors, windows, on your clothes, and on your pets. Your HVAC system pulls air from every room, and those allergens get drawn into the return vents. Some get trapped in your air filter. The rest settle in your ductwork. Over months and years, your ducts accumulate layers of allergenic material. Then, every time your heating or air conditioning kicks on, the system pushes air through those contaminated ducts—and redistributes allergens into your living spaces. It’s a cycle that keeps you exposed to allergens 24/7, even when pollen counts outside are low. Common Allergens Hiding in Your Ductwork Your ducts can harbor a surprising variety of allergy triggers: Dust Mites These microscopic creatures are one of the most common indoor allergens. Dust mites feed on dead skin cells and thrive in warm, humid environments—exactly what they find inside ductwork. It’s not the mites themselves that trigger allergies, but their waste particles and body fragments, which become airborne when disturbed. According to the Asthma and Allergy Foundation of America, dust mites are a trigger for approximately 20 million Americans. Pet Dander If you have cats, dogs, or other furry pets, their dander circulates through your HVAC system constantly. Pet dander is incredibly lightweight and sticky—it clings to duct surfaces and accumulates over time. Even if you’ve rehomed a pet or moved into a home where pets previously lived, dander can persist in ductwork for months or years. Pollen Summerville’s pollen seasons are no joke. Oak, pine, and grass pollen blanket the Lowcountry in spring, while ragweed takes over in fall. Pollen enters your home and gets pulled into your HVAC system, where it settles in ducts and recirculates long after the outdoor pollen count drops. This explains why some allergy sufferers experience symptoms year-round indoors, even during “off” seasons. Cockroach and Pest Debris Cockroach droppings, saliva, and body parts are potent allergens, particularly for people with asthma. Rodent urine and dander also trigger allergic reactions. If pests have ever inhabited your ductwork, their allergenic debris may still be present. Fabric Fibers and Household Dust General household dust—a mixture of fabric fibers, dirt, skin cells, and miscellaneous particles—accumulates in ducts and contributes to overall allergen load. How Duct Cleaning Reduces Allergy Symptoms Professional duct cleaning addresses allergies by removing contaminated material at the source. Here’s how the process helps: Eliminates Accumulated Allergens Over years of operation, your ducts collect pounds of dust, dander, and debris. A thorough cleaning extracts this material using specialized equipment—typically truck-mounted or portable vacuums with HEPA filtration that captures particles as small as 0.3 microns. Stops the Recirculation Cycle Once allergens are removed from your ductwork, your HVAC system stops redistributing them every time it runs. This immediately reduces your exposure and gives your immune system a break. Improves Air Filter Effectiveness When ducts are heavily contaminated, allergens can bypass your filter or overwhelm it quickly. Clean ducts mean your filter can do its job more effectively, capturing incoming allergens before they enter the duct system. Enhances Overall Indoor Air Quality Removing allergens from ducts is one component of better indoor air quality. Many allergy sufferers notice improvements in breathing comfort, sleep quality, and overall well-being after professional duct cleaning. What the Research Says The EPA takes a measured stance on duct cleaning, noting that it hasn’t been proven to prevent health problems. However, they acknowledge that duct cleaning may be beneficial when ducts are visibly contaminated with dust, debris, or pest droppings. The National Air Duct Cleaners Association (NADCA) points to studies showing that HVAC systems accumulate significant biological and particulate contamination over time, and that proper cleaning can reduce airborne contaminants. For allergy sufferers specifically, the logic is straightforward: if allergens are present in your ducts, removing them reduces your exposure. While duct cleaning isn’t a cure for allergies, it eliminates one significant source of triggers. When Duct Cleaning Makes the Biggest Difference for Allergies Duct cleaning isn’t necessary for everyone, but certain situations make it especially valuable for allergy sufferers: You’ve Never Had Your Ducts Cleaned If your home is more than five years old and the ducts have never been professionally cleaned, significant allergen accumulation is likely. You Recently Adopted or Rehomed Pets Bringing a new pet into your home—or removing one—changes your indoor allergen profile. Cleaning ducts after a pet transition removes accumulated dander and gives you a fresh start. You Moved Into a Previously Owned Home You inherit the previous occupants’ allergens when you buy a home. Their pets, their dust, their pollen exposure—it’s all in the ductwork. Cleaning ducts when you move in eliminates that history. Your Allergies Are Worse Indoors Than Outdoors If you experience more symptoms inside your home than outside—especially when the HVAC system is running—your ductwork may be a primary allergen source. You’re Preparing for Allergy Season Cleaning ducts before Summerville’s spring or fall pollen seasons removes accumulated pollen from previous years and reduces your baseline allergen exposure before new pollen arrives. You’ve Completed Home Renovations Construction projects generate enormous amounts of dust that settles in ductwork. Post-renovation duct cleaning is essential for allergy sufferers.

Can Dirty Air Ducts Make You Sick? What Summerville Homeowners Need to Know
Can Dirty Air Ducts Make You Sick? What Summerville Homeowners Need to Know Yes, dirty air ducts can contribute to health problems—particularly respiratory issues, allergy symptoms, and irritation of the eyes, nose, and throat. When contaminated ducts circulate air through your home, they distribute dust, pet dander, pollen, bacteria, and other pollutants into every room. The Environmental Protection Agency (EPA) ranks indoor air pollution among the top five environmental health risks. While dirty ducts aren’t the sole cause of illness, they can worsen symptoms for people with asthma, allergies, or compromised immune systems and create discomfort for otherwise healthy individuals. What’s Actually Living in Your Ductwork? Your air ducts are out of sight, so they’re easy to forget. But over time, they collect more than just dust. Here’s what accumulates in a typical Summerville home’s ductwork: Dust and Dust Mites Every home generates dust—a mixture of dead skin cells, fabric fibers, dirt tracked indoors, and microscopic debris. Dust mites, tiny creatures invisible to the naked eye, feed on this material and thrive in ductwork. Their waste particles become airborne when your HVAC system runs, triggering allergic reactions in sensitive individuals. Pet Dander If you have dogs, cats, or other furry pets, their dander (tiny flakes of skin) circulates through your HVAC system and settles in ductwork. Even homes without current pets may harbor dander from previous occupants. Pollen Summerville’s oak trees, pine trees, and grasses produce significant pollen loads in spring and fall. Pollen enters your home through open doors, windows, and on clothing, then gets pulled into your HVAC system and trapped in ducts. Bacteria Biological contaminants can survive in ductwork, particularly in areas with moisture or organic debris. While your HVAC system isn’t a primary transmission route for most illnesses, contaminated ducts can harbor bacteria that affect indoor air quality. Pest Debris Rodents, insects, and other pests sometimes make their way into ductwork. They leave behind droppings, urine, dander, and in some cases, carcasses—all of which decompose and release particles into your air supply. Construction Debris If your home was recently built or renovated, your ducts may contain drywall dust, sawdust, insulation fibers, and other construction materials that weren’t properly cleaned out. Moisture and Potential Mold Concerns The Lowcountry’s humid subtropical climate creates conditions where moisture can accumulate in ductwork—through condensation, leaks, or high humidity. When moisture persists, it can lead to mold growth, which requires assessment and remediation by certified mold specialists. If you notice musty odors or see discoloration around vents, have a qualified mold professional inspect your system before scheduling duct cleaning. The Health Effects of Poor Indoor Air Quality The connection between dirty ducts and health problems comes down to indoor air quality (IAQ). When your HVAC system circulates contaminated air, you breathe in whatever’s been collected in your ductwork. Respiratory Symptoms The most common complaints linked to poor indoor air quality include: Coughing and wheezing Shortness of breath Chest tightness Frequent respiratory infections Sinus congestion These symptoms often worsen when the HVAC system is running and improve when you leave the house—a telltale sign that indoor air quality may be the culprit. Allergy and Asthma Flare-Ups For the estimated 50 million Americans with allergies and 25 million with asthma, contaminated ductwork can be a significant trigger. Dust mites, pet dander, and pollen are all common allergens that accumulate in ducts. If you notice that allergy symptoms persist indoors even when pollen counts are low outside, your ductwork may be recirculating allergens trapped from previous seasons. Eye, Nose, and Throat Irritation Airborne particles and biological contaminants can irritate mucous membranes, causing: Itchy, watery, or red eyes Runny or stuffy nose Sore throat Frequent sneezing These symptoms often get dismissed as “just allergies” or a lingering cold, but they may indicate an indoor air quality problem. Headaches and Fatigue Poor indoor air quality has been linked to headaches, difficulty concentrating, and general fatigue. This cluster of symptoms—sometimes called “sick building syndrome”—occurs when people spend extended time in spaces with inadequate ventilation or contaminated air. Skin Irritation Dry, itchy skin and unexplained rashes can result from airborne irritants circulating through your home. Dust mite waste is a common culprit. Serious Health Risks for Vulnerable Populations While healthy adults may experience only mild discomfort from poor indoor air quality, certain groups face greater risks: Population Elevated Risk Infants and young children Developing respiratory systems are more susceptible to damage Elderly adults Weakened immune response and existing health conditions People with asthma Contaminated air triggers attacks and worsens control People with allergies Constant exposure prevents symptom relief Immunocompromised individuals Higher risk of infection from airborne bacteria People with COPD Airborne irritants exacerbate breathing difficulties How to Tell If Your Ducts Are Affecting Your Health Connecting health symptoms to dirty ductwork isn’t always straightforward. Here are signs that your HVAC system may be contributing to health problems: Symptoms Improve When You Leave Home If your coughing, sneezing, or headaches ease up when you’re at work or running errands but return when you get home, indoor air quality deserves investigation. Multiple Household Members Are Affected When several people in your home experience similar symptoms—especially respiratory issues or allergies—a shared environmental factor like contaminated ductwork is more likely than coincidence. Symptoms Worsen When HVAC Runs Pay attention to whether symptoms intensify when your heating or air conditioning kicks on. If the correlation is consistent, your ducts may be distributing contaminants. Musty Odors If you notice a musty or stale smell when your system runs, moisture may have accumulated in your ductwork. This warrants inspection—and if mold is suspected, contact a certified mold assessment professional before proceeding with duct cleaning. Excessive Dust Despite Regular Cleaning Do you find yourself dusting constantly, only to see dust reappear within days? Your ducts may be the source, redistributing particles every time the system cycles. Recent Renovation or Water Damage Construction projects and water intrusion events introduce contaminants into ductwork. If health symptoms appeared after either situation, your ducts should be inspected. What the Research

Your HVAC system is the heart of your home, working tirelessly day in and day out to fight off the Lowcountry humidity and keep your family comfortable. But like any workhorse, it won’t last forever. If your aging unit is struggling, constantly breaking down, or sending your energy bills soaring, it might be time for an upgrade. A modern, high-efficiency HVAC system isn’t just a replacement, it’s a long-term investment in your home’s value, health, and comfort. At Coastal Carolina Comfort, HVAC installation is one of the most important services we offer to our neighbors, from the Charleston coast to the quiet streets of Summerville. Is It Time to Replace Your HVAC System? Repairs can often extend the life of a unit, but there comes a point when a replacement is the smarter financial decision. Here are the key signs it’s time to start planning for an installation: Your System is Over 10 Years Old: The average lifespan of an HVAC system in our coastal climate is 10-15 years. If yours is in that range, it’s living on borrowed time. Rising Energy Bills: An older system loses efficiency, working harder and using more electricity to do the same job. A new system can often pay for itself in energy savings. Frequent and Costly Repairs: Are you on a first-name basis with your repair technician? If a repair costs 30-50% of a new unit, it’s time to replace it. Poor Performance: Your home has hot and cold spots, the system runs constantly, or it just can’t keep up on the hottest days. Strange Noises: Loud grinding, banging, or rattling that persists after a tune-up can indicate a major component is about to fail.
