Huntsville Housing Stock
Half the homes in Huntsville were built before 1984 (Census ACS median), so the typical house is about 42 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. About 55,000 households here own their home, 58.1% of the occupied total. With a median household income of $70,778 and a median home value of $263,100, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 25 hail days and 82 days with damaging thunderstorm winds in Madison County. The largest hail reported was 2.75 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. Madison County also had 11 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
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Ask what the emergency fee is before the truck is sent.
- Maintenance plans often put members first in line for emergency calls.
