When your air conditioner quits in a Knightsville summer, you don't wait on a truck routed in from Charleston. Coastal Carolina Comfort dispatches NATE-certified technicians from our Lipman Street shop right here in Summerville, minutes from Knightsville — so most Knightsville homeowners see a tech the same afternoon. Honest diagnosis, written pricing before any work, and parts already on the truck.
Knightsville is an established Summerville community along US-78 in Dorchester County — a mix of decades-old homes and newer infill. Many systems here are well past the 10-year mark, and some still run phased-out R-22, so repairs skew toward aging equipment and an honest repair-or-replace conversation rather than a default upsell. Add Summerville's relentless summer humidity and a heavy spring pine-pollen load that packs condenser coils, and Knightsville sees a predictable set of breakdowns every cooling season.
Many Knightsville owners are facing their first serious HVAC repair, and that's exactly where a national franchise tends to push a full replacement. Our techs diagnose the real problem first — and tell you honestly when a repair is the right call.
The most common Knightsville no-cool call: a failed capacitor or contactor stops the compressor while the fan keeps spinning. Often a same-visit fix. See why your AC runs but isn't blowing cold air or a failed capacitor.
Restricted airflow or a slow leak ices the evaporator coil and shuts cooling down in humid weather. We trace the root cause — see a frozen evaporator coil and refrigerant leaks.
Buzzing, a unit that won't turn on, water leaking inside, or a system short cycling on and off — each points to a specific fault we diagnose before we quote.
The same four-step process every Knightsville service call runs through, from the moment you pick up the phone to a verified, working system.
We send a tech from Lipman Street, minutes away here in Summerville — no waiting on a truck from Charleston. Most Knightsville calls are seen the same afternoon.
Refrigerant pressures, capacitors and electrical, airflow across the coils, thermostat, and the condensate drain — checked properly, not guessed.
You get a flat-rate written estimate in plain language before any wrench turns. If replacement is the smarter money, we'll say so.
We fix it with manufacturer-spec parts, confirm the temperature split across the coil, and leave you a written summary with a parts-and-labor warranty.
Our trucks carry the parts behind most Lowcountry breakdowns, so the majority of Knightsville repairs finish in one visit.
Most Knightsville AC repairs land between $150 and $650, depending on the part. Capacitors and thermostats sit at the low end; compressor and refrigerant work costs more. You always get the number in writing before we start — and financing with 0% interest for 24 months is available on larger repairs and replacements.
Call (843) 708-8735A Knightsville family called on a 96° Saturday — system running, no cold air, a toddler napping upstairs. Our tech was on-site that afternoon, traced it to a failed dual-run capacitor on an 8-year-old builder-grade condenser, replaced it from the truck, and verified the temperature split before leaving.
"Cool air by dinner. They showed me the estimate before touching anything and didn't try to sell me a whole new unit."
AC died in Knightsville on the hottest weekend of the year. Tech came out same day, found a bad capacitor, fixed it fast, and the price was exactly what he wrote down. No upsell.
First big AC problem since we moved to Knightsville. They explained the whole diagnosis in plain English and had us cooling again that afternoon. Honest people.
Our system kept freezing up. Coastal found a refrigerant leak the last company missed, repaired it properly, and didn't push a replacement. Dispatched from Summerville so they were here quick.
