Fairburn homes get furnace repair, AC repair and gas heating safety checks from us. Winter matters here more than many expect: the Christmas 2022 freeze left Fairburn with low water pressure, and a dead furnace on a night like that puts pipes at risk. Summer brings the usual long Atlanta-area cooling season and the repairs that come with it.
The old county seat and its housing
Fairburn was the seat of Campbell County from 1871 until that county was absorbed into Fulton in 1932, and it had 16,483 residents in 2020. A town with that much history has houses from many eras, each with its own heating setup, from older gas furnaces in crawl spaces to newer heat pumps.
Today it is part of Fulton County, and we cover it alongside the other south county cities.
Gas furnaces and the company behind the pipe
Atlanta Gas Light has been a pipes-only delivery company since 1998 under Georgia's 1997 gas deregulation law, so customers on its system buy their gas from a marketer approved by the Public Service Commission. That split matters when the heat stops. If your bill is current and other gas appliances work, the problem is almost always in the furnace, not the supply.
Most no-heat calls come down to a handful of parts: a cracked hot surface ignitor, a dirty flame sensor, a pressure switch that will not close, or an inducer motor that has worn out. Repairing a furnace usually means testing each in order. If you smell gas, leave the house and call your gas marketer or the utility's emergency line before calling us.
Christmas 2022 and January 2025
After the Christmas 2022 freeze, burst pipes and water main breaks hit metro Atlanta, and Fairburn saw low pressure. January 2025 then ran about 4F colder than normal, with winter storms on January 10 and 21 and a low of 14F on January 22.
Those nights are when an untested furnace fails. A fall furnace tune-up cleans the burners and flame sensor, checks the flue and tests the safety controls while the weather is mild. If the heat does quit on a freezing night, we answer 24/7. For odd smells on the first cold start, see what furnace smells on the first cold night mean.
Heating and cooling work that fits Fairburn
Furnace Repair
Fairburn's 2022 low-pressure episode showed how quickly a heating failure becomes a plumbing risk.
Furnace Tune-Up
A fall check catches weak ignitors and dirty flame sensors before nights like January 2025's 14F low.
Gas Furnace Safety & CO Testing
Older gas furnaces in Fairburn houses deserve heat exchanger and flue draft checks.
AC Repair
The same homes face long 90-degree stretches every summer that wear out electrical parts.
Furnace Replacement
When an older Fairburn furnace has a cracked heat exchanger, replacement is the safe path.
Fairburn heating and air questions
The most common causes are a cracked hot surface ignitor, a dirty flame sensor that shuts the burners off after a few seconds, or a pressure switch that will not prove the vent is clear. The furnace runs a safety sequence and locks out after failed tries.
Leave the house first. Then call the gas emergency line. Atlanta Gas Light delivers the gas through its pipes, while your marketer handles billing. Once the line is declared safe, we can inspect and repair the furnace itself.
Have the furnace or heat pump checked in the fall, replace the filter, test carbon monoxide detectors, and know where your water shutoff is. The 2022 freeze brought low water pressure to Fairburn, and steady heat is the surest protection for pipes.
An electric space heater with tip-over shutoff, kept away from curtains and bedding, can bridge a night. Never use a gas oven or a grill indoors for heat, because of carbon monoxide. Call us instead of waiting; we answer 24/7.
Not automatically. What matters is the condition of your ducts, not the town's history. We look for crushed runs, disconnected boots and undersized returns, and measure static pressure. Many systems need sealing, not replacement.
