NOAA storm reports for Hinds County show 16 hail days and 73 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2.5 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. Hinds County also had 15 tornado days in that period.

Mississippi Licensing and Efficiency Rules
Mississippi 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 Mississippi license or registration number before the visit.
Before You Hire
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Book maintenance twice a year, once before summer and once before winter.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.

Heat Pump Repair Questions from Jackson Homeowners
What does heat pump repair cost in Jackson?
Most bills land between $160 and $790, including the service call. A typical visit is about $510. 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.
