Takes about a minute. No obligation.
A heat pump flagged for repair in this county has already been running against a heavy weather load for years. 238 severe weather events were recorded in Mobile County, Alabama between 2015 and 2024. At that rate, the compressor, capacitors, and contactor accumulate stress steadily, not in isolated bursts, and a contractor diagnosing a repair here checks those components against that history before drawing any other conclusion. An intermittent fault or a hard failure in a system this county's climate has worked hard points to cumulative wear, and that changes what a contractor prices and what they replace.
Older ductwork in a house this age seals poorly, and the joints are where a heat pump repair often starts rather than inside the unit. Half the homes in Mobile County, Alabama were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor who opens the system in housing like this frequently finds refrigerant lines that have worked through many Alabama summers, contactor points that have burned and pitted, and capacitors that are marginal rather than failed outright. Parts for systems installed into this stock are still available, but the repair scope tends to be wider than a single failed component once the access panels come off.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners recognize first, a metal cabinet sitting on a pad beside the house that holds the compressor and the outdoor coil. The compressor is where a contractor often starts: when it fails, the system stops moving heat entirely. The outdoor coil sits around it and is the first place a technician looks for physical damage, refrigerant leaks, or blockage.
Inside the house, the air handler holds the indoor coil and the blower fan, which pulls air across the coil and pushes it through the home. The refrigerant lines connect the two units and carry the working fluid between them. The reversing valve, housed in the outdoor unit, is what lets a heat pump heat and cool, and a fault there shows up as a system stuck in one mode.
The drawing beside this text shows the general layout of a heat pump system, and a licensed contractor will determine which parts apply to the specific setup in your home.
