A heat pump that stops performing in Lavaca County is almost always carrying an explanation inside the unit itself. 26 severe weather events were recorded in Lavaca County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition, and it does not account for most of what contractors find when they open a system. Worn contacts, degraded refrigerant charge, and compressor fatigue tied to age or deferred service are what the work turns up. The weather record belongs in the picture, but it is rarely what the repair bill traces back to.
Ductwork and wiring in a house built before the late seventies were put in for equipment that bore no resemblance to a heat pump. Half the homes in Lavaca County, Texas were built in 1977 or earlier (2020-2024 ACS 5-year). That gap shapes what a contractor finds once the unit is open: capacitors, contactors, and refrigerant lines that have run through a long string of Texas summers, and electrical connections that may have been patched more than once along the way. Parts that fit the specific system in a house this age are not always in regional stock, and confirming availability is part of pricing the job correctly.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil. The compressor is the part a contractor reaches for early in a diagnosis: when it fails, the system stops moving heat entirely. The condenser coil surrounds it, and a bent or dirty coil shows up as poor performance before anything else does.
Inside the house, the air handler contains the evaporator coil and the blower fan. The evaporator coil is where refrigerant does its work on the indoor air, and a slow refrigerant leak shows first as ice forming on that coil. The blower fan pushes conditioned air into the home, and a failing motor or worn capacitor behind it often announces itself as weak airflow or an unusual sound.
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 Lavaca County
Heat pumps run hardest when the weather outside pulls them furthest from equilibrium, and weather in Lavaca County can be uneven enough that the strain shows up in the equipment over time. Repair needs here are shaped by local conditions, which is why what happens outside matters to what a contractor finds inside.
