A contractor diagnosing a heat pump here looks at components that have been running against real cumulative stress. 197 severe weather events were recorded in Wise County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of life for any system in this county, and the compressor, capacitor, and refrigerant lines each absorb a share of it. On a repair call, those are the places a contractor starts, not because age and maintenance do not matter, but because the weather load here is heavy enough to show up in the hardware first.
Opened up, a heat pump in this county's typical housing stock tends to settle the repair question fast: the refrigerant circuit, the reversing valve, the capacitors. Half the homes in Wise County, Texas were built in 1996 or earlier (2020-2024 ACS 5-year). Equipment running in houses built around that period has cycled through enough summers and winters that contractors regularly find components whose part numbers have gone dark. When a part is still made, the repair is straightforward. When it is not, the homeowner is choosing between a sourced substitute and a full replacement, and that decision gets made at the unit, not before.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is where most repair calls begin. When it fails, the system runs but moves no heat. The condenser coil surrounds it, and a bent or dirty coil puts strain on everything behind it.
The air handler lives inside, usually in a closet, attic, or utility room, and it contains the evaporator coil and the blower. The expansion valve and the refrigerant lines connect the two units. A contractor also checks the reversing valve, which sits in the outdoor unit and is the part that lets a heat pump heat and cool.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and house.

Severe Weather Events in Wise County
Extreme weather puts a hard load on heat pump systems, compressing the demand for heating and cooling into the same short windows that stress components most. How often that happens in Wise County shapes how hard the equipment works and how often repair becomes necessary.
