A contractor quoting a heat pump repair in this area starts with the system itself: how old it is, how it has been maintained, and which components are showing wear. 36 severe weather events were recorded in San Augustine County, Texas between 2015 and 2024. At that rate, severe weather is something equipment here encounters from time to time, not something it grinds against season after season. A failing compressor, a refrigerant problem, or a worn contactor in this county points to service history and age before it points to weather load. That is where a contractor looks first, and that is where the repair scope gets set.
Older heat pump systems reveal their real repair scope once a contractor gets inside the unit, and what they find there drives everything that follows. Half the homes in San Augustine County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). A county where the typical house has seen that many years of equipment cycles means the system a contractor opens could belong to any of several generations of heat pump technology. Some of those generations take refrigerants or control boards that are no longer in steady supply. The diagnosis is often the quick part. Sourcing the right components for an older system, or deciding whether a repair is still practical, is where a job in stock like this gets complicated.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize: a metal cabinet that sits on a pad beside the house and holds the compressor and the outdoor coil. The compressor is usually the first suspect when a heat pump stops moving heat in either direction. A failed coil, a refrigerant leak at the fittings, or a seized fan motor in that same cabinet can each produce symptoms that look alike from inside the house.
The air handler sits inside, most often in a utility closet, attic, or basement, and it holds the indoor coil and the blower that pushes conditioned air through the house. The reversing valve, which lives in the outdoor unit, is what lets the system run in both heating and cooling modes, and a stuck or failed valve is a repair the contractor will test for early. The thermostat and the refrigerant lines connecting both units are also part of what gets checked.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your specific house and situation.
