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.
| Heating degree days / year | 1,403 |

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.
