A contractor quoting heat pump repair here starts by ruling out the ordinary suspects: refrigerant loss, worn contactors, capacitors that gave out from age and run hours. 60 severe weather events were recorded in Franklin County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event in this county rather than a standing condition, so a stressed compressor or a seized fan motor almost certainly has a different story behind it. The contractor checks installation quality and service history before weather load, because weather load here is unlikely to be the answer.

Stock built that long ago has cycled through more than one generation of equipment, which means the heat pump a contractor opens today is probably not the original but still old enough to sit in a parts gray zone. Half the homes in Franklin County, Texas were built in 1988 or earlier (2020-2024 ACS 5-year). When a refrigerant valve or a reversing valve fails in a system of that age, the question is whether the manufacturer or an aftermarket supplier still cuts that part, and the answer shapes the repair more than the diagnosis does. A contractor who can source it proceeds; one who cannot is quoting a replacement job whether the homeowner expected that or not.

The Parts of a Heat Pump a Contractor Checks First

The outdoor unit holds the compressor and the condenser coil. It sits outside the house, usually on a pad beside the foundation, and it is where most mechanical failures begin. When a heat pump stops heating or cooling, the compressor and the refrigerant lines running to and from that cabinet are where a contractor looks first.

Inside the house, the air handler contains the evaporator coil and the blower fan, and together they move conditioned air into the living space. The expansion valve, which sits between the two coils, controls refrigerant flow and is a common source of pressure and temperature faults. The reversing valve, also inside the refrigerant circuit, is what lets the system switch between heating and cooling modes, and a stuck or leaking reversing valve produces symptoms that can look like almost any other failure.

The drawing shows a general layout of these components, and a licensed contractor determines which parts apply and what condition they are in for your specific home.

Severe Weather Events in Franklin County

Extreme weather puts heat pumps under real mechanical stress, and that stress accumulates over time into the failures that need repair. How hard the weather bears down here shapes how hard the equipment works, which makes local storm history a direct part of the repair picture.
