A heat pump repair in Houston County starts with a question a contractor has to settle before anything else: what actually wore this component out. 248 severe weather events were recorded in Houston County, Alabama between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, not a rare event, so a compressor or reversing valve that has quit on a homeowner in this area has been running against real cumulative load. A contractor who skips that history and reaches straight for the cheapest fix risks replacing the wrong part.
Stock built around the time most Houston County homes went up has had its equipment swapped out and swapped out again since, and each round of replacement can leave a repair contractor chasing parts for a system that sits in an awkward spot on the availability curve. Half the homes in Houston County, Alabama were built in 1985 or earlier (2020-2024 ACS 5-year). A heat pump that has been in the ground for a stretch of that housing's life may run refrigerants or draw on components that manufacturers have phased or restricted, which turns a straightforward repair call into a sourcing problem before any labor starts.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is where most repair calls begin. It houses the compressor, which is the heart of the system, along with the condenser coil and a fan that moves air across it. When the system stops heating or cooling, or runs but does nothing, the contractor starts here.
Inside the house, the air handler holds the evaporator coil and the blower motor that pushes conditioned air through your home. The reversing valve, which lets the system shift between heating and cooling, sits in the outdoor unit and is a common focus when the system works in one mode but not the other. The expansion valve and refrigerant lines connect the two units and are checked when temperatures at the coils are off.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply to your specific installation.
