A heat pump repair in Titus County starts with the system itself, not the weather outside. 60 severe weather events were recorded in Titus County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition, so a failed reversing valve or a compressor running outside its pressure range is far more likely to trace back to how old the unit is or how it has been maintained than to storm load. A contractor will check refrigerant charge, contactor wear, and coil condition before the weather enters the conversation at all.

Older wiring and refrigerant lines outlast the original equipment they served, and what a contractor finds when a heat pump is opened here reflects that history. Half the homes in Titus County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). Connections corrode, insulation on wiring dries and cracks, and service fittings that were installed for earlier refrigerant types can complicate a straightforward repair. Whether the electrical at the disconnect still meets what the heat pump draws is a question the contractor answers at the unit, not from the address.

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 start. When it struggles or fails, the system stops moving heat altogether. The coils in that same cabinet can collect grime or take physical damage, and either condition blocks the heat exchange the compressor depends on.

Inside the house, the air handler contains a second coil and the blower that pushes conditioned air into the living space. The reversing valve, which lives in the outdoor cabinet, is the part that lets a heat pump both heat and cool. When it sticks or fails, the system may be locked into one mode. The expansion valve and refrigerant lines connect the two units and are checked when the system is losing capacity or running but not conditioning.

The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to your specific installation.
