A contractor called out for a heat pump repair in Walker County starts by ruling out the ordinary culprits: worn contactors, degraded refrigerant charge, failing capacitors that accumulate problems quietly over years. 79 severe weather events were recorded in Walker County, Texas between 2015 and 2024. At that rate, severe weather is an occasional presence in a system's life, not the dominant one. A unit that has been running without regular service, or that was poorly matched to the house at install, will fail long before storm load accounts for the trouble. The weather record exists, and a contractor notes it, but it rarely changes the diagnosis.
Opened units in older housing stock tend to answer their own question. Half the homes in Walker County, Texas were built in 1989 or earlier (2020-2024 ACS 5-year). A heat pump that has run through that many summers leaves physical evidence inside: corroded contacts, capacitors that test weak, refrigerant lines showing wear at the fittings. A contractor working through a repair here looks at those components first, because in stock of this age the fault is usually present and findable rather than intermittent or ambiguous. Parts availability for equipment of this vintage is the variable that shapes the scope after that.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil, which are the parts that move heat between your home and the outside air. When the system stops heating or cooling, a contractor goes to this unit first. A failed compressor, a refrigerant leak at the coil, or a burned contactor all show up here.
Inside the house, the air handler holds the evaporator coil and the blower fan, which pulls air across the coil and pushes it through the vents. An expansion valve sits between the two coils and controls refrigerant flow. A reversing valve inside the system switches the direction of that flow depending on whether you need heat or cooling, and it is a common point of failure when the system runs but delivers the wrong temperature.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply and what condition they are in for your specific house.
