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 |
|---|---|
| Cooling degree days / year | 2,931 |
| Nights at or below 32°F | 15 |
| Days above 90°F | 73 |
| Average low / high | 59.7°F / 78.5°F |
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.
When It Makes Sense
- The house heats with electric baseboard, oil or propane
- Energy bills are higher than you want them to be
- Your AC needs replacing, and you'd like cheaper heat at the same time
What Moves the Price
- Size in tons, and whether the unit is cold-climate rated
- Variable-speed (inverter) or single-stage compressor
- Electrical panel capacity and wiring
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- A ducted system or a ductless mini-split

What the Quote Should Cover
- Line set, drain and electrical hookups
- Commissioning and warranty registration
- Thermostat setup and backup heat settings
- A load calculation and equipment selection
- The outdoor heat pump and an indoor air handler or coil
Alabama Permits, Efficiency Rules and Rebates
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). Expect the contractor to pull a mechanical permit for a replacement job in Mobile. If a bidder suggests skipping it, move on. Also ask for a Alabama license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask your electric utility and state energy office what heat pump rebates are open right now.
- Make sure the installer sized the system for your heating load, not only cooling.
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.

Heat Pump Installation Questions from Mobile Homeowners
How much is heat pump installation in Mobile?
Plan on $5,400 to $13,200, with most jobs near $9,700. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Mobile?
Between late fall and early spring. With 73 days over 90°F, Mobile contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
