Takes about a minute. No obligation.
A heat pump in McLennan County has been running against real, recurring pressure, and a contractor working a repair here has to sort out what that pressure actually produced. 174 severe weather events were recorded in McLennan County, Texas between 2015 and 2024. At that rate, wear on components like the compressor, reversing valve, and capacitor accumulates as a matter of course, not as a fluke. A contractor will check those parts first and trace whether the failure followed from load or from something else, because the repair scope and the parts ordered depend on which it was.
Ductwork and wiring in houses this old have been spliced, patched, and pushed through many seasons before the current equipment ever ran on them. Half the homes in McLennan County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). That history concentrates the real diagnostic work inside the unit itself: a contractor opening a heat pump here finds contactors, capacitors, and refrigerant components that carry the full record of that service load, and those are the parts that decide what the repair costs and how long it holds.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil, and it sits on a pad outside the house. The compressor is where most repair calls start. It moves refrigerant through the system, so when it labors or fails, the whole system stops moving heat. The condenser coil surrounds it, and a bent or fouled coil shows up fast as poor performance.
Inside the house, the air handler contains the evaporator coil and the blower motor, usually in a closet, attic, or utility room. The evaporator coil can ice over or develop a refrigerant leak, while the blower motor is what pushes conditioned air into the living space. The reversing valve, which sits in the outdoor unit, is specific to heat pumps and is what a contractor checks when the system heats but will not cool, or the other way around.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components need attention in your specific home.

Severe Weather Events in McLennan County
Weather puts heat pumps to work in ways that wear on the equipment over time. How hard a system is pushed year to year is a local fact, and repair needs in McLennan County follow from it.
