Takes about a minute. No obligation.
A contractor quoting heat pump repair in Callahan County starts by ruling out the obvious culprits: how old the unit is, whether it was sized right, and how consistently it has been serviced. 94 severe weather events were recorded in Callahan County, Texas between 2015 and 2024. That puts this county in roughly the middle of the national range, so the weather load is real but not the kind that dominates a diagnosis. A compressor that has failed here almost certainly failed from wear, not from an exceptional beating the climate handed it. The contractor checks refrigerant levels, electrical components, and coil condition before the weather conversation starts.
Ductwork in houses this old was put in for whatever system was running at the time, then adapted again when that system was replaced. Half the homes in Callahan County, Texas were built in 1977 or earlier (2020-2024 ACS 5-year). By the time a contractor opens a heat pump in stock like this, the question that decides the job is usually not what failed but whether the part it takes is still being made. Discontinued components push a repair toward a full replacement faster than the failure itself would.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil, and it sits outside the house on a pad or bracket. The compressor is where a contractor looks first when a heat pump stops moving heat at all. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each kill the system in its own way.
Inside the house, the air handler contains the evaporator coil, the blower motor, and the expansion valve. The blower pushes conditioned air through the home, and the expansion valve controls refrigerant flow between the two coils. A reversing valve connects the two sides of the system and is what lets a heat pump switch between heating and cooling modes; when it sticks or fails, the system gets locked into one.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply to your specific house.
