A contractor called out to repair a heat pump in Washington County is not walking into a system battered by relentless weather. 36 severe weather events were recorded in Washington County, Texas between 2015 and 2024. At that rate, most systems here have spent the bulk of their lives running against ordinary seasonal demand, not exceptional stress. When a compressor fails or a reversing valve sticks, the weather record gives the contractor little to point at. What they find instead is wear from age, a refrigerant charge that was never quite right, or a filter that went too long between changes. The repair scope follows from that, not from the storm calendar.
Ductwork and wiring in homes this age have already been touched more than once, worked around, spliced, and rerouted to suit whatever equipment came before. Half the homes in Washington County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). By the time a heat pump goes down in a house that has seen that many service cycles, what a contractor finds when they open the unit tends to be refrigerant-side wear or electrical contact failure rather than a house that cannot support a repair. Parts availability is the question worth asking early, because a system running in stock this old may predate some component lines still stocked locally.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize on sight. It sits outside the house and holds the compressor and condenser coil, both of which a contractor examines closely when the system is losing heating or cooling capacity. The compressor is usually the first suspect when the unit runs but produces little effect.
Inside the house, the air handler holds the evaporator coil and the blower, and a fault in either one shows up as poor airflow or uneven temperatures room to room. The reversing valve, which lives in the outdoor unit, is specific to heat pumps and is what a contractor checks when the system heats in cooling mode or fails to switch between the two.
The drawing shows a typical layout, and a licensed contractor determines which parts apply to the specific system and conditions in your home.
