A heat pump that stops performing in Mason County is almost certainly failing for reasons the weather did not cause. 59 severe weather events were recorded in Mason County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition the equipment fights through season after season, which means worn contactors, low refrigerant from a slow leak, or a compressor past its service life are likelier culprits than storm-driven stress. A contractor working a repair here will check installation quality and component age before reaching for weather as an explanation.
Ductwork that has been patched, rerouted, or resealed across multiple service generations tells a contractor something specific: what the opened system needs may be straightforward, but whether the surrounding infrastructure will hold that repair is a separate question. Half the homes in Mason County, Texas were built in 1976 or earlier (2020-2024 ACS 5-year). A heat pump running in a house that old has almost certainly outlived at least one round of ductwork work, and what those earlier jobs left behind shows up once the unit is open. Corroded connections, mismatched fittings, and sections sealed with materials that have since hardened all bear on whether a repair holds or fails again within a season.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the outdoor coil. When the system stops heating or cooling, the compressor is often where a contractor looks first, since it drives the whole cycle. The outdoor coil can also fail, collect debris that blocks airflow, or develop refrigerant leaks at its connections.
Inside the house, the air handler moves conditioned air through the home and contains the indoor coil and the blower motor. The expansion valve sits between the two coils and controls refrigerant flow. A faulty reversing valve, which tells the system which direction to run, is another piece a contractor checks when the unit runs but heats or cools on the wrong cycle.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply to your specific house and equipment.

Severe Weather Events in Mason County, Year by Year
Extreme weather puts heat pumps under load at the worst possible moments, and the stress accumulates over time. How often that happens in Mason County shapes how hard local equipment works and how soon repair needs tend to surface.
