We are the dedicated Gas Safety & Combustion Team for all of Summerville and Dorchester County.
Hear a click but no 'whoosh'? Summerville's humidity often corrodes igniters. We stock replacements for Carrier & Lennox units to restore heat instantly.
We don't just guess. We inspect your Heat Exchanger for cracks—the #1 cause of dangerous carbon monoxide leaks in older Summerville furnaces.
Your gas valve needs to be tuned, not just swapped. We use digital combustion analyzers to ensure your system burns clean, safe, and efficient.
Families in Summerville rely on natural gas for powerful heating, but gas furnaces come with specific risks. If your system is clicking but not starting, or if you catch a faint whiff of ‘rotten eggs,’ you need a certified expert, not a handyman.
From vintage systems in Historic Downtown to the modern gas furnaces found in Cane Bay Plantation, Coastal Carolina Comfort is dispatched from Lipman St with the specific igniters, flame sensors, and safety switches needed to fix your heat today.
The #1 reason Cane Bay furnaces stop. The sensor gets dirty and shuts off the gas for safety.
If you hear a 'click' but no 'whoosh' of fire, your hot surface igniter has likely burned out.
If the filter is clogged, the furnace overheats and the limit switch kills the flames while the fan keeps blowing.
On older units, a draft may have blown out the pilot. We can safely relight and adjust it. Common in older homes in the Historic District.
Normal for the first run of the season. Dust settles on heat strips.
Melting wire insulation caused by loose connections. Dangerous.
The motor is overheating because the bearings are locked up.
DANGER: If you smell sulfur or rotten eggs anywhere in your Summerville home, turn off your system immediately and evacuate. You may have a gas leak.
"DANGER: This is 'delayed ignition.' Gas builds up before lighting. Turn it off and call us immediately."
Your system is trying to light the gas but failing. Usually a bad igniter or flame sensor.
Likely the Inducer Motor. This fan pushes dangerous exhaust gases out of your home.
Dirty gas burners causing rough combustion. This wastes fuel and can create soot.
We provide flat-rate pricing for all Dorchester County neighbors. Minor ignition repairs typically run $150–$350. We never start work without an upfront quote.
STOP! This indicates a natural gas leak. Turn off your furnace immediately, evacuate the house, and call us or the gas company. Do not ignore this smell.
It is likely a safety shut-off. If the filter is dirty or the flame sensor is coated in carbon, the system kills the fire but keeps the fan running to prevent overheating.
Not always. A 'Red Tag' means a technician found a safety hazard, often a cracked heat exchanger. We offer a Free Second Opinion on Red Tags to verify if the unit is truly dangerous or if it can be safely repaired.
From our headquarters in Summerville, SC, Coastal Carolina Comfort focuses on speed. Because we deploy trucks directly from Lipman St, we avoid the traffic delays that slow down companies driving up from Charleston. Whether you are dealing with a gas furnace failure in Lindera Preserve or a heating emergency in The Coves, our local team is minutes away.
