Mobile Weather and HVAC Load
Mobile logs 1,403 heating degree days and 2,931 cooling degree days in a normal year, based on the closest NOAA weather station. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Count on roughly 15 nights below 32°F and 73 afternoons past 90°F in a typical year. On the cooling side, a 2,000 sq ft house here usually needs around 3.5 tons. A tight, well-insulated house may get by with half a ton less.

Mobile Housing Stock
Half the homes in Mobile were built before 1974 (Census ACS median), so the typical house is about 52 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. Mobile has roughly 40,000 owner-occupied homes, or 51.4% of households. Homes here have a median value of $170,300 and households a median income of $51,090. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 10 hail days and 32 days with damaging thunderstorm winds in Mobile County. The largest hail reported was 1.5 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. Mobile County also had 18 tornado days in that period.
Symptoms Worth a Service Call
- Water pooling around the indoor unit
- Ice on the refrigerant lines or the indoor coil
- The outdoor unit hums, but the fan doesn't spin
- The breaker trips when the AC kicks on
- The AC runs, but the air coming out is warm
What Moves the Price
- The service call or diagnostic fee
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
- Whether the equipment sits in a tight attic or on a roof
- Nights, weekends and holidays
- Refrigerant type and how many pounds it takes

What the Quote Should Cover
- Checking refrigerant pressures
- A test run
- Clearing the drain line if it's clogged
- Diagnosis and electrical testing
- Replacing the failed part
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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Alabama the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask for the per-pound refrigerant price before any work starts.
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
- If you see ice, shut the system off. Running it frozen can kill the compressor.
