Takes about a minute. No obligation.
A heat pump in Houston County that needs repair has almost certainly spent its life in mild weather, not grinding through the kind of seasonal punishment that wears out compressors and coils on a system's own schedule. 77 severe weather events were recorded in Houston County, Texas between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a standing operating condition, so a contractor opening a failed unit looks first at refrigerant levels, contactor wear, and how regularly the system has been serviced. Storm load is a real variable, but in a county with a record this light, age and skipped maintenance produce the failures that actually show up on the job.
Half the homes in Houston County, Texas were built in 1981 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that age has almost certainly been replaced at least once since the house was built, and the unit running now may itself be old enough that its compressor valves, reversing valve, or control board are no longer in regular production. When a contractor opens the system, the first question is whether the failed component can still be sourced, or whether a repair becomes a replacement by default. That answer drives the scope and the price more than the failure itself does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil. It sits on a pad outside the house and handles the bulk of the heat exchange. When a heat pump loses heating or cooling capacity, or makes noise it did not make before, the compressor and the coil inside that cabinet are where a contractor looks first.
The air handler lives inside the house, usually in a utility closet, attic, or basement, and it contains the indoor coil and the blower that moves air across it. The reversing valve, which is what lets a heat pump heat in winter and cool in summer, sits in the refrigerant line between these two units. A faulty reversing valve is a common reason a system blows warm air when it should be blowing cold, or the reverse.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to your specific house and equipment.

Severe Weather Events in Houston County
Houston County's climate puts real stress on heat pump systems, cycling them hard through heat, humidity, and whatever weather rolls through. That workload accumulates, and when something fails, the cause is often local conditions rather than a generic equipment problem.
