A contractor quoting a heat pump repair in Duval County has to settle one question early: what actually wore this system down. 38 severe weather events were recorded in Duval County, Texas between 2015 and 2024. At that rate, severe weather lands occasionally, not constantly, which means most systems here have spent their working lives in ordinary conditions. Refrigerant leaks, failing capacitors, and compressor fatigue in this county trace back to age and maintenance gaps far more often than to storm load. A contractor who assumes otherwise is solving the wrong problem.
Ductwork and electrical service installed for earlier equipment carry their own wear, and in stock this age a repair call often surfaces problems outside the heat pump before the technician reaches the unit itself. Half the homes in Duval County, Texas were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor who opens the system and finds a failed capacitor or a worn contactor still has to account for what surrounds it: disconnects that may not meet current draw requirements, line sets that have corroded at the joints, or duct connections that have loosened over decades of thermal cycling. The part that failed is frequently the straightforward piece of the job.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the outdoor coil. The compressor is where a contractor starts when a heat pump stops moving heat, because a failed compressor changes the whole diagnosis. The outdoor coil picks up or releases heat depending on the season, and bent fins or refrigerant problems show up there.
The indoor air handler mounts inside, usually in a closet, attic, or utility space, and it holds the indoor coil and the blower. The blower pushes conditioned air through the house, and a failing motor or clogged coil often explains weak airflow or uneven temperatures. The reversing valve, also inside the refrigerant loop, is what lets the system switch between heating and cooling, and a stuck valve is a common reason a heat pump will only run in one mode.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply to the specific system and conditions in your home.
