A heat pump repair in this county starts with what the system has already been through. 163 severe weather events were recorded in Harrison County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a contractor working a repair has to separate wear that came from that sustained load from wear that came from installation quality or a maintenance gap. Refrigerant lines, capacitors, and contactors all carry the outdoor load, and in an area with a record like this one, those are the components a contractor checks before anything else gets priced.
Half the homes in Harrison County, Texas were built in 1984 or earlier (2020-2024 ACS 5-year). A heat pump installed into a house that old was put in well after the walls went up, chosen to fit what was already there, and its condition since has been shaped by use and climate, not by the building around it. When a repair call comes in, what the opened unit contains is the question: the refrigerant circuit, the reversing valve, the capacitors and contactors. Whether the coil has corroded or a board has failed is settled by what a contractor sees on the bench, not by what year the permit was pulled on the house.
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 failures show up first. When it labors or quits, the system either runs poorly or stops moving heat altogether. The coils in that cabinet transfer heat to or from the outdoor air, and bent fins or refrigerant loss will show up here.
Inside the house, the air handler hangs in a closet, attic, or mechanical room and pushes conditioned air through the home. It holds a second coil and a blower motor, both of which a contractor will inspect when the system underperforms or makes noise. A reversing valve ties the two sides together and tells the system which direction to move heat. When a heat pump blows the wrong temperature, that valve is one of the first things checked.
The drawing shows a typical layout, and a licensed contractor will assess which parts and conditions apply to your specific home.

Severe Weather Events in Harrison County
Heat pumps work hardest when the weather outside is most extreme, and that workload accumulates over years. How often severe weather hits Harrison County shapes how hard the equipment runs and what kinds of repair needs show up.
