A contractor called out for a heat pump repair in Cass County has to work out what the system has been carrying, not just what broke last week. 107 severe weather events were recorded in Cass County, Texas between 2015 and 2024. At that rate, severe weather is a routine operating condition here, not an occasional disruption, and the load it puts on refrigerant lines, contactors, and fan motors adds up over years of cycling. A part that looks like the obvious culprit can be a symptom of broader wear, and a repair scoped without accounting for that history is likely to come back.
Half the homes in Cass County, Texas were built in 1980 or earlier (2020-2024 ACS 5-year). A house built that long ago has almost certainly had at least one round of equipment replacement since the original install, which means the heat pump running in it today is not the system the house was designed around. When a contractor opens a unit to diagnose a fault, what drives the repair scope is whether the replacement parts that particular system takes are still in production and how long sourcing them runs. A heat pump in stock of this vintage can be any age, any brand, any refrigerant generation.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and one set of coils. The compressor is where most repair calls begin. When it labors or fails, the system loses its ability to move heat in either direction. The coils in that cabinet can corrode, bend, or ice over, each of which shows up differently and points a contractor toward a different fix.
Inside the house, the air handler holds a second set of coils and the blower that pushes conditioned air through the home. The reversing valve, which is what lets a heat pump heat and cool, sits in the refrigerant line and is a part contractors check specifically when the system works in one mode but not the other. The refrigerant line itself runs between the two units and carries the signs of leaks or blockages that explain a lot of underperforming systems.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to the specific equipment and configuration in your house.

Severe Weather Events in Cass County by Year
Extreme weather puts heat pumps under stress they were not designed to absorb continuously, and that stress accumulates into repair needs. How hard the weather pushes in Cass County shapes how hard local equipment has to work.
