A contractor quoting a heat pump installation in Dimmit County is not ignoring the weather record, but the record itself tells a specific story. 15 severe weather events were recorded in Dimmit County, Texas between 2015 and 2024. At that rate, severe weather is an event here, not a constant condition, which means the load it places on equipment is real but not the defining pressure a contractor has to design around. Sizing decisions and installation quality carry more weight than storm exposure. A unit put in badly will fail on a calm summer day.
Ductwork laid down for an older system carries assumptions about airflow that a heat pump does not always share. Half the homes in Dimmit County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump here has to check whether the existing duct configuration moves the volume a new unit demands, and whether the electrical service will support what it draws at startup and at steady state. Both answers come from what is physically in the house, and both shape the scope before any equipment gets ordered.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchanges heat with the outside air. The indoor air handler mounts inside, often in a closet, utility room, or attic, and moves conditioned air through the home. Together these two units are what a contractor sets into place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two and carrying the refrigerant that makes the system work. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a secondary drain line from the air handler to carry away condensate.
The drawing shows a representative layout, and a licensed contractor determines what the installation calls for in your specific home.
