A heat pump in this area has been running against a genuine weather load, and a contractor diagnosing a repair here has to work out how much of what they find is weather-driven wear before they can name a cause. 140 severe weather events were recorded in Brazos County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and components that cool, compress, and shed heat outdoors carry that load every season. A refrigerant issue or a failing contactor gets a different repair scope depending on whether cumulative stress is part of the picture, so a contractor checks the outdoor unit's condition closely before settling on a cause.
Heat pump systems put into houses built well before they were commonly installed often run on adapted infrastructure, and what a contractor finds once the unit is open can shift the repair scope significantly. Half the homes in Brazos County, Texas were built in 1997 or earlier (2020-2024 ACS 5-year). A heat pump dropped into a house from that era is running in ductwork and on wiring that was configured for something else first. If a refrigerant-side fix turns out to share a cause with undersized airflow or a struggling circuit, those become part of what the contractor has to report on. The repair is straightforward until the opened system says otherwise.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize on sight. It sits outside the house and holds the compressor and the condenser coil. The compressor is where most repair work begins: when it fails, the system stops moving heat entirely. The condenser coil, which surrounds the compressor, is where a contractor looks for refrigerant leaks, physical damage, and dirt buildup that forces the compressor to work harder than it should.
Inside the house, the air handler holds the evaporator coil, the blower motor, and the expansion valve. The evaporator coil pulls heat from the indoor air, the blower motor pushes that air through the house, and the expansion valve controls the refrigerant flow between the two units. A refrigerant line set runs between the indoor and outdoor units, and a contractor checks it along with the reversing valve, which is the part that lets a heat pump shift between heating and cooling.
The drawing shows the general layout of the system, and a licensed contractor determines which parts apply and what work is needed in your specific home.

Severe Weather Events in Brazos County
Heat pumps work hardest when the weather outside pushes hardest against them. What storms and extreme conditions this county records year to year is a direct measure of the strain local equipment absorbs, and strain is what brings repair needs forward.
