A contractor quoting a heat pump repair in Llano County has to decide what actually wore the system down. 77 severe weather events were recorded in Llano County, Texas between 2015 and 2024. At that rate, severe weather is a recurring presence in a system's life, real enough that a contractor checks for stress on electrical components and the refrigerant circuit, but not so relentless that it automatically explains a failed part. Age and original installation quality are still live suspects, and a good diagnosis separates those from weather load before a repair scope gets written.
Ductwork and wiring in these houses have already outlasted whatever ran in them first. Half the homes in Llano County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A heat pump that lands in stock like this inherits that layered history, and when something fails, the opened system shows a contractor splices, prior fixes, and components sourced across different service visits rather than a clean original installation. The repair quote depends on what that history produced inside the unit, and whether the replacement part the system needs is still in current supply.
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, which is the component a contractor goes to first when a heat pump stops doing its job. The air handler lives inside, usually in a closet, attic, or utility room, and it moves conditioned air through the home.
The reversing valve sits inside the outdoor unit and is what allows a heat pump to shift between heating and cooling. The expansion valve and refrigerant lines connect the two main units, and a contractor will check both for pressure problems or leaks when the system is underperforming. The thermostat is the last piece a contractor tests, since a wiring fault there can look like a mechanical failure.
The drawing shows a general layout of these components, and a licensed contractor determines which of them applies to the repair in your specific home.
