GAS FURNACE WON’T IGNITE IN SUMMERVILLE?

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.

WHY IS MY GAS FURNACE BLOWING COLD AIR?

Dirty Flame Sensor

The #1 reason Cane Bay furnaces stop. The sensor gets dirty and shuts off the gas for safety.

Bad Igniter

If you hear a 'click' but no 'whoosh' of fire, your hot surface igniter has likely burned out.

Overheating (Limit Switch)

If the filter is clogged, the furnace overheats and the limit switch kills the flames while the fan keeps blowing.

Pilot Light Out

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.

SMELLING GAS OR BURNING DUST?

Dust "Burn-Off"

Normal for the first run of the season. Dust settles on heat strips.

Electrical Short

Melting wire insulation caused by loose connections. Dangerous.

Seized Blower Motor

The motor is overheating because the bearings are locked up.

"Rotten Egg" Smell

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.

SCARY SOUNDS FROM YOUR GAS FURNACE?

Loud "Boom" on Startup

"DANGER: This is 'delayed ignition.' Gas builds up before lighting. Turn it off and call us immediately."

Rapid Clicking

Your system is trying to light the gas but failing. Usually a bad igniter or flame sensor.

High-Pitched Whine

Likely the Inducer Motor. This fan pushes dangerous exhaust gases out of your home.

Low Rumbling

Dirty gas burners causing rough combustion. This wastes fuel and can create soot.

COMMON SUMMERVILLE GAS FURNACE QUESTIONS

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.

Yes. We are specialists in the Carrier and Lennox systems commonly installed in new construction areas like Nexton and Cane Bay.

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.
