HVAC Repair & Replacement
Heating, cooling, and air handler repair plus full system replacement for North Georgia homes.
HVAC systems in North Georgia work hard year-round — humid summers push AC units past 95°F load days, and damp winter cold cycles strain heat pumps and gas furnaces. Knowing whether a noisy condenser, weak airflow, or rising power bill points to a $250 capacitor or a $9,000 full system swap is the difference between a smart repair and an overpaid panic call.

Typical costs
Service calls run $95–$185. Common repairs (capacitor, contactor, refrigerant top-off) land $250–$900. Full system replacement (14–17 SEER2) typically $7,200–$12,500 installed.
Most common problems we see
- AC blowing warm air after a humid week (often a frozen coil or low refrigerant)
- Outdoor unit humming but fan not spinning (failed capacitor)
- Short-cycling — system kicks on and off every few minutes
- Musty smell from vents (microbial growth on the evaporator coil)
- Heat pump stuck in defrost during cold snaps
- Rising electric bill with no comfort change
Homeowner money-saving tips
- 1Get three written quotes — North Georgia HVAC pricing varies 25–40% between contractors for identical equipment
- 2Ask for the Manual J load calculation before accepting a replacement size
- 3Replace 1" filters every 60 days; clogged filters cause ~30% of premature compressor failures
- 4Check Georgia Power and Jackson EMC rebates — up to $750 on qualifying heat pump installs
FAQ
How long should an HVAC system last in North Georgia?
12–15 years for AC condensers, 15–20 for gas furnaces, and 12–16 for heat pumps. High humidity and pollen load shorten the low end of those ranges.
Is a heat pump or gas furnace better here?
For most of Gwinnett, Hall, and Jackson counties a modern variable-speed heat pump is now the lowest total cost of ownership. Gas still wins if you already have a line and winter setpoints below 65°F.
Should I repair a 12-year-old AC or replace it?
If the repair is over $1,200 or involves the compressor or evaporator coil, replacement is almost always the better financial call.
Why does my AC freeze up?
Most commonly a dirty filter, blocked return, or low refrigerant. Turn the system off, let it thaw for 4 hours, and run fan-only before calling — that alone tells the tech whether it's airflow or a leak.
