A contractor diagnosing a heat pump in Montgomery County checks the compressor, the reversing valve, and the refrigerant circuit for what years of cycling have done to them. 66 severe weather events were recorded in Montgomery County, Alabama between 2015 and 2024. That weather history puts a genuine load on equipment, but it falls short of what drives early compressor failure or coil degradation on its own. Age and how well the original install was done carry more weight in most repair findings here. A contractor who skips those questions and blames a hard season is working with the wrong frame.
Half the homes in Montgomery County, Alabama were built in 1979 or earlier (2020-2024 ACS 5-year). A heat pump running in a house of that era is often connected to wiring and line sets that were not originally put in for it. When a contractor opens the unit, the fault inside may be straightforward, but what the surrounding infrastructure looks like shapes whether that repair holds. Corroded connections, undersized wiring, or line sets that have been spliced and re-spliced over the years can turn a clean parts swap into a longer job.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit sits outside the house and holds the compressor and condenser coil, which are the parts that move heat between the refrigerant and the outside air. When either fails, the system loses its ability to condition the air at all. The air handler lives inside, typically in a closet or attic, and pushes conditioned air through the home.
The refrigerant lines run between the two units and carry the working fluid that makes the whole cycle possible. A metering device, usually mounted near the indoor coil, controls how much refrigerant enters that coil, and a fault there often looks like an airflow or temperature problem until a contractor traces it to the source.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components and conditions apply to your specific house.

Severe Weather Events in Montgomery County
Weather puts real stress on heat pump equipment, and that stress accumulates differently depending on where the unit runs. What happens outside in Montgomery County shapes how hard the equipment works and how often repair becomes necessary.
