The median Mableton home dates to 1985, according to the Census ACS. That makes the typical house about 41 years old.

Homes here have a median value of $306,200 and households a median income of $84,662. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Cobb County show 9 hail days and 27 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.75 inches across.

Cobb County also had 3 tornado days in that period.

Georgia Licensing and Efficiency Rules
Georgia is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Georgia the company should carry a state license or registration. Ask for both.
Before You Hire
- Book maintenance twice a year, once before summer and once before winter.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Keep two feet clear around the outdoor unit, including snow.

Heat Pump Repair Questions from Mableton Homeowners
What does heat pump repair cost in Mableton?
Most bills land between $180 and $880, including the service call. A typical visit is about $570. Night and weekend calls cost more.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
