A heat pump that stops working in Dimmit County has almost certainly not been worn down by relentless weather pressure. 15 severe weather events were recorded in Dimmit County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event in this area, and contractors working repairs here find that compressor failures, refrigerant issues, and electrical faults trace back to equipment age and how consistently the system was serviced, not to storm load. A contractor will still check for physical damage, but it moves down the list fast.

Ductwork in a house this old has already outlasted at least one refrigerant standard and, in all likelihood, one or two systems before whatever is running now. Half the homes in Dimmit County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). That history means a contractor opening a heat pump here is looking at components that have logged years of sustained summer load, and the repair scope follows what they actually find inside: a failed contactor, a capacitor at the edge of its rating, refrigerant levels that drifted over repeated seasons. Parts for systems this age are still available, but not always from the nearest shelf, and a quote that does not account for sourcing is a quote that changes.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is the piece most homeowners recognize on sight. It holds the compressor, which is the part that does the heaviest work, and the outdoor coil, which transfers heat between the refrigerant and the outside air. When a heat pump stops heating or cooling the way it should, the compressor and that coil are where a contractor looks first.
Inside the house, the air handler pushes conditioned air through the home and contains its own coil, a blower motor, and the expansion valve that controls refrigerant flow between the two units. The refrigerant lines running between the outdoor unit and the air handler, along with the reversing valve that switches the system between heating and cooling modes, round out the pieces a contractor works through when tracing a fault.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts and conditions apply to your specific house.
