Montgomery Housing Stock
Half the homes in Montgomery were built before 1977 (Census ACS median), so the typical house is about 49 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 54.3% of occupied homes, roughly 44,000 households. Homes here have a median value of $148,500 and households a median income of $55,687. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Montgomery County show 12 hail days and 21 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. Montgomery County also had 7 tornado days in that period.

Alabama Licensing and Efficiency Rules
Alabama 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 Alabama 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 Montgomery Homeowners
What does heat pump repair cost in Montgomery?
Most bills land between $170 and $830, including the service call. A typical visit is about $530. 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.
