A heat pump repair in Tom Green County starts with a harder diagnosis question than most homeowners expect. 350 severe weather events were recorded in Tom Green County, Texas between 2015 and 2024. At that rate, every major component in the system has been cycling against real stress for years, and a contractor pulling the unit apart will find wear patterns that reflect it. The compressor, the reversing valve, and the electrical contacts all carry that load differently, and which one gave out first tells the contractor whether this is a weather-driven failure or a parts-life failure. Those are different repairs with different bills attached.
Ductwork laid down for a different system and electrical service wired for something else are what contractors open into on a large share of repair calls here. Half the homes in Tom Green County, Texas were built in 1980 or earlier (2020-2024 ACS 5-year). A heat pump added to a house that age was almost certainly a retrofit, which means the refrigerant lines, the air handler connections, and the wiring path behind the unit reflect whoever adapted what was already there. When a repair opens that up, the condition of those older connections shapes what the fix actually costs and whether a single component swap is enough to hold.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is the heart of the system, and when it fails, the unit runs but moves no heat. The condenser coil transfers that heat to or from the outside air, so a damaged or dirty coil is a common reason a system struggles to keep up.
Inside the house, the air handler contains the evaporator coil and the blower fan, which pulls conditioned air through your living space. The refrigerant lines connect both units, and the reversing valve inside the system tells the heat pump which direction to move heat. A faulty reversing valve is one of the first things a contractor checks when a heat pump cools but will not heat, or the other way around.
