A contractor called out to repair a heat pump in Madison County has to settle one question before pricing any part: whether what failed wore out under genuine weather load or simply reached the end of its service life. 576 severe weather events were recorded in Madison County, Alabama between 2015 and 2024. At that rate, severe weather is a standing condition here, and the difference between a compressor that gave out under sustained stress and one that failed from age alone changes what gets replaced and what gets left. Capacitors, contactors, and refrigerant connections all carry that load differently, and the contractor checks them against it.
Half the homes in Madison County, Alabama were built in 1992 or earlier (2020-2024 ACS 5-year). A house built around that year has had its heat pump swapped in or upgraded since, and the building itself is rarely where the problem lives. What shapes the repair is what the opened system actually contains: whether the compressor, reversing valve, or control board it takes still has parts available, or whether a failed component now belongs to a production run that ended years ago. A contractor working through a repair here finds that question waiting well before they find anything to blame on the house.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil, both of which are common starting points when a heat pump stops heating or cooling properly. The compressor pressurizes refrigerant; when it fails, the system produces little or no conditioned air. The condenser coil surrounds it, and a bent or dirty coil can push the compressor into fault before the compressor itself is the problem.
Inside the house, the air handler contains the evaporator coil, the blower motor, and the expansion valve. The evaporator coil can ice over when refrigerant charge is off or airflow is blocked. The blower motor moves air across that coil and through the house, and the reversing valve, which sits in the refrigerant line, is what lets the system switch between heating and cooling modes. A contractor checks each of these when diagnosing where the fault actually is.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply and what work is needed in your specific home.
