DeKalb County had 1 hail day and 28 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. DeKalb 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

  • Keep two feet clear around the outdoor unit, including snow.
  • Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
  • Light frost on the outdoor unit in winter is normal. A solid block of ice is not.

Heat Pump Repair Questions from Dunwoody Homeowners

What does heat pump repair cost in Dunwoody?

Most bills land between $220 and $1,090, including the service call. A typical visit is about $700. Night and weekend calls cost more.

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.

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.
