Fayette County households get heat pump repair, AC repair and backup heat service from us, and the county's winter swings are what test most of that equipment. Heat pumps have to defrost cleanly and hand off to strips or gas on the coldest nights, then carry a long humid summer. Sizing and controls matter as much as the outdoor unit.
Forty-five thousand homes and two very different cities
Fayette County was created in 1821 and had 119,194 residents and 45,202 housing units in 2020. Its county seat, Fayetteville, keeps the 1825 Fayette County Courthouse, the oldest surviving courthouse in Georgia, and is also home to Trilith studios. That mix of an old courthouse square and new studio-era building means the equipment we find ranges widely.
Peachtree City is the opposite case. It was settled in 1959, incorporated in 1962 and had 38,244 residents in 2020, along with more than 100 miles of golf cart paths. Its neighborhoods grew up after central air was common, so the work there leans toward replacing and tuning systems rather than retrofitting ducts into houses built without them.
What a hard Georgia freeze does to a heat pump
The National Weather Service recorded 8F in Atlanta on December 24, 2022. January 2025 ran about 4F colder than normal, with winter storms on January 10 and 21 and a low of 14F on January 22. A heat pump keeps working at those temperatures, but its output falls as the outdoor air gets colder, and the defrost cycle runs more often.
Three things decide whether the house stays warm: a defrost board and sensor that clear ice on time, heat strips or a furnace that come on when the heat pump falls short, and a thermostat set up to call that backup correctly. When a system ices into a solid block or the strips never engage, a heat pump service call usually comes down to one of those three.
Choosing the next system in Fayette
Since January 1, 2023, split-system heat pumps must meet at least 14.3 SEER2 and 7.5 HSPF2 nationally. HSPF2 is the heating rating, and it matters more here than many buyers expect because of those freezing nights. Variable-speed models hold capacity better in the cold and run longer, gentler cycles in summer.
Some Fayette homes do well with a heat pump paired with a gas furnace, letting the furnace take over below a set outdoor temperature. Our guide to heat pump or gas furnace choices walks through the tradeoff before you call.
Heating and cooling work that fits Fayette County
Heat Pump Repair
Freezes like January 2025's 14F low are when defrost boards and reversing valves give out.
Heat Pump Installation
Replacements in Fayette should be chosen on HSPF2 heating performance, not just the cooling rating.
Dual Fuel Heat Pump Systems
Homes with gas available can let a furnace carry the coldest nights and a heat pump handle the rest.
Air Handler & Heat Strip Repair
Heat strip sequencers and relays are the backup that fails quietly until a freeze exposes it.
Smart Thermostat Installation
Heat pump and dual fuel wiring has to call auxiliary heat correctly or the strips run when they should not.
Commercial HVAC Repair
Fayetteville's studio-era growth adds commercial buildings with rooftop and split equipment.
Fayette County heating and air questions
It may be in defrost, which briefly reverses the system to melt ice off the outdoor coil. That is normal for a few minutes. If cool air lasts much longer, or the outdoor coil is a solid block of ice, the defrost control or backup heat has likely failed and needs a look.
HSPF2 is a heat pump's seasonal heating efficiency rating. The national minimum since 2023 is 7.5. In a county that sees freezes like the 8F night in December 2022, a higher HSPF2 or a variable-speed model holds heat output better when it is coldest.
Not usually, because the city was settled in 1959 and its homes were built with central air in mind. We still check duct leakage, return size and static pressure, since a new system on undersized or leaky ducts loses much of its rated performance.
It depends on whether you have gas service and how you feel about strip heat on the coldest nights. A heat pump alone works when the backup is sized well. Dual fuel suits homes that already have a sound gas furnace and want it to cover hard freezes.
No. Strips should help on cold mornings and during defrost, not run constantly. Common causes are a low refrigerant charge, a thermostat wired to call auxiliary heat too early, or a stuck sequencer. Constant strip heat shows up quickly on the power bill.
