A heat pump failure in Austin County sends a contractor looking at the system's history before anything else. 31 severe weather events were recorded in Austin County, Texas between 2015 and 2024. At that rate, severe weather is an occasional pressure on equipment, not a steady one, so when a compressor quits or a reversing valve sticks, the weather record is unlikely to be the explanation. What a contractor finds instead are the usual culprits: a refrigerant charge that drifted years ago, a filter that went too long between changes, or components that simply ran their course. The weather here does not let a diagnosis skip those questions.
Refrigerant blends and compressor designs have changed enough times since the older half of this county's homes were built that what a contractor finds inside a failed heat pump often calls for parts that current suppliers carry on thin inventory or no longer stock at all. Half the homes in Austin County, Texas were built in 1992 or earlier (2020-2024 ACS 5-year). A system installed into that stock will have been updated at some point, but the refrigerant circuit it runs on may not match anything in a standard repair kit today. That gap between what the unit needs and what the supply chain holds is what sets the scope of the job, and sometimes its cost.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, sitting on a pad beside the house. Inside its cabinet are the compressor and the outdoor coil. The compressor is the heart of the system, and when a heat pump stops doing its job, that cabinet is where a contractor looks first.
Inside the house, the air handler holds the indoor coil and the blower that moves conditioned air through the home. A reversing valve connects the two sides of the system and is what allows a heat pump to shift between heating and cooling. When either heating or cooling fails but not both, that valve is a common place to start.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply and what condition they are in for your specific home.
