Roswell Housing Stock
The median Roswell home dates to 1989, according to the Census ACS. That makes the typical house about 37 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 71.2% of occupied homes, roughly 25,000 households. Homes here have a median value of $520,500 and households a median income of $124,422. Those two numbers drive the labor adjustment in our estimate.
Fulton County had 11 hail days and 52 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Fulton 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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Georgia license or registration number before the visit.
Before You Hire
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Book maintenance twice a year, once before summer and once before winter.
- Keep two feet clear around the outdoor unit, including snow.

Heat Pump Repair Questions from Roswell Homeowners
What does heat pump repair cost in Roswell?
Most bills land between $230 and $1,110, including the service call. A typical visit is about $710. 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.
