A heat pump repair in this area starts with what the system has already been through. 93 severe weather events were recorded in Jefferson County, Texas between 2015 and 2024. At that rate, severe weather is not an occasional disruption but a steady condition the equipment has been operating against, and that matters when a contractor opens a unit and finds a worn compressor or a refrigerant issue. The question is whether the failure came from load accumulation or from something the homeowner can fix going forward. A contractor who skips that question may replace a part that will wear out again on the same schedule.
Ductwork and wiring adapted over the years carry their own record of what previous repairs left behind. Half the homes in Jefferson County, Texas were built in 1978 or earlier (2020-2024 ACS 5-year). A heat pump running in a house of that vintage has usually been opened before, and what a contractor finds inside reflects that: fittings tightened over older fittings, refrigerant lines that may have been recharged rather than traced, connections that show the work of hands other than their own. The repair scope follows from what the opened system actually contains, not from what the permit says.
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 component a contractor reaches for first when a heat pump stops moving heat altogether, and the outdoor coil, which is where refrigerant releases or absorbs heat depending on the season. A refrigerant leak, a failed capacitor, or a seized compressor each show up here.
Inside the house, the air handler contains the indoor coil and the blower fan that pushes conditioned air through the home. The expansion valve, which controls refrigerant flow between the two coils, sits close by and is a common fault point when the system runs but fails to reach the set temperature. The reversing valve, which switches the system between heating and cooling, is another piece a contractor examines when the mode stops changing.
The drawing shows the general layout of these components, and a licensed contractor determines what applies to the specific equipment and configuration in your home.

Severe Weather Events in Jefferson County
Jefferson County's climate puts real stress on heat pump systems, which run year-round to move heat in and out of a home regardless of what the weather is doing outside. How hard that equipment works, and how often it needs repair, is a local question shaped by local conditions.
