Takes about a minute. No obligation.
A heat pump in this area has been running against real pressure. 271 severe weather events were recorded in Carson County, Texas between 2015 and 2024. At that rate, components like the reversing valve, capacitors, and refrigerant lines accumulate stress from repeated thermal and electrical loading, and a contractor repairing a unit here checks those parts for cumulative wear rather than treating the failure as a standalone event. The diagnosis comes before the part order.
Ductwork and wiring in houses this old were not laid for heat pumps, but that is an installation question. What bears on repair work is what the equipment itself has been through. Half the homes in Carson County, Texas were built in 1959 or earlier (2020-2024 ACS 5-year). A system running in stock that old has absorbed a long stretch of Texas summers and winters, and when a contractor opens the unit, what they find in the compressor and refrigerant circuit reflects that accumulated load. Parts worn to that degree are sometimes still available; sometimes the line has been discontinued, and sourcing becomes its own part of the job.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is where most repair calls begin. It houses the compressor, which pressurizes the refrigerant, and the condenser coil, which exchanges heat with the outside air. When either goes wrong, the whole system stops doing its job. The fan that pulls air across that coil is another common fault point a contractor reaches for early.
Inside the house, the air handler holds the evaporator coil and the blower that pushes conditioned air through your home. The reversing valve, which shifts the system between heating and cooling, sits in the refrigerant line and is a frequent subject of repair work. The refrigerant lines themselves run between the two units and can develop leaks that show up at the fittings.
The drawing shows a typical layout, and a licensed contractor determines which parts apply to your specific system and what work each one needs.

Severe Weather Events in Carson County
Heat pumps work hardest when the weather outside is most extreme, and that workload adds up over time. How often Carson County sees severe weather shapes what the equipment endures and what repair needs tend to look like here.
