A contractor sizing up a heat pump repair in this area starts with what the system has already been through. 523 severe weather events were recorded in Denton County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and components that carry the heaviest load in rough conditions, compressors, reversing valves, and capacitors, are the first things a contractor checks when a system starts failing. Age and maintenance history still matter, but in a county where severe weather runs this frequently, a worn compressor or a degraded capacitor is as likely to trace back to cumulative weather load as to anything else, and a contractor working a repair here prices the job with that in mind.

Stock built around that era was already carrying heat pump systems before the technology settled into its current form, which means the failure patterns a contractor uncovers are shaped by decades of thermal cycling, refrigerant transitions, and successive repairs layered on top of one another. Half the homes in Denton County, Texas were built in 2003 or earlier (2020-2024 ACS 5-year). When a technician opens a unit in a house this age, what they find often reflects not one failure but a sequence of them, each previous fix leaving its own mark on the coil, the reversing valve, or the electrical connections inside the cabinet. Parts for equipment of this vintage are still manufactured, so supply is rarely what stalls the job. What stalls it is accurately reading which layer of wear is the one that caused today's problem.
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 the most worked part in the system, and when a heat pump stops moving heat in either direction, a contractor starts there. The condenser coil wraps around the inside of that cabinet and is the next thing they look at.
Inside the house, the air handler contains the blower motor and the evaporator coil, and it is responsible for moving conditioned air into the living space. The reversing valve, also inside the refrigerant circuit, is what lets the system heat as well as cool, and a stuck or failed valve is a common reason a heat pump blows the wrong temperature air. The expansion valve and the refrigerant lines that connect both units round out what a contractor will trace when the outdoor unit checks out but the problem persists.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your specific house and situation.

Severe Weather Events in Denton County
Heat pumps work against whatever the local climate puts out, and stress on the system accumulates with the weather. How hard that equipment runs, and how often it fails, is shaped by what happens outside.
