A heat pump repair in Knox County starts with the system itself, not the sky. 79 severe weather events were recorded in Knox County, Texas between 2015 and 2024. At that rate, severe weather is an occasional fact of life here rather than a constant operating pressure, which means the compressor that quit or the refrigerant line that failed is almost certainly carrying a different story. A contractor working a repair here asks how old the unit is, how well it was installed, and whether it has been serviced, because those factors carry more weight than the area's weather record does.
Ductwork in a house this old was sized and routed for something that has since been replaced, possibly more than once, and what a contractor finds once a heat pump is open often reflects that layered history more than it reflects the current system's age. Half the homes in Knox County, Texas were built in 1966 or earlier (2020-2024 ACS 5-year). A heat pump running in stock like this can fail in ways that point straight back to how the refrigerant lines were run or how the air handler was fitted into a space built for a different type of system. The parts the opened unit takes may still be available, but whether the repair holds depends on what surrounds it.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize on sight. It sits outside on a pad or bracket and holds the compressor and the condenser coil. Those two components are where a contractor looks when a heat pump stops moving heat altogether, makes a grinding or rattling sound, or cycles on and off without reaching the set temperature.
Inside the house, the air handler holds the evaporator coil and the blower fan. The air handler pushes conditioned air through the home, so a frozen coil, a failed blower motor, or a dirty evaporator coil shows up as weak airflow or rooms that won't reach temperature. Running between the two units, the refrigerant lines and the reversing valve are what the contractor checks when the system blows the wrong temperature for the season.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your specific home and situation.
