Montgomery Weather and HVAC Load
Montgomery logs 1,755 heating degree days and 2,846 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. A normal year brings 40 nights at or below freezing and 92 days over 90°F. 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.

| Nights at or below 32°F | 40 |

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.
Symptoms Worth a Service Call
- Ice on the refrigerant lines or the indoor coil
- The breaker trips when the AC kicks on
- The outdoor unit hums, but the fan doesn't spin
- The AC runs, but the air coming out is warm
- Water pooling around the indoor unit
What Moves the Price
- Nights, weekends and holidays
- Refrigerant type and how many pounds it takes
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
- The service call or diagnostic fee
- Whether the equipment sits in a tight attic or on a roof
We kept the national figures close to unchanged for Montgomery using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover

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
- Swap the air filter and check the breaker before you call anyone.
- 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.
