A contractor quoting a heat pump install in Willacy County starts with the building load, not a defensive spec list built around weather. 26 severe weather events were recorded in Willacy County, Texas between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a constant operating pressure on outdoor equipment. What that means for installation is that the sizing question and the quality of the refrigerant line work and electrical connections matter more than any assumption about storm exposure. A system that fails early in this county almost always traces back to how it was sized or set up.
Ductwork laid in when a house was built gets sized for whatever the builder was putting in that year, and in Willacy County the gap between that original design and what a heat pump actually needs is where most installations get complicated. Half the homes in Willacy County, Texas were built in 1984 or earlier (2020-2024 ACS 5-year). A heat pump moves a larger volume of air at lower temperature differentials than the resistance or gas heat it often replaces, so ducts that were adequate for the old system can restrict the new one enough to hurt its efficiency and shorten its life. A contractor quoting the job has to assess the existing duct layout and the electrical service before the unit itself can be priced accurately.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, sitting on a pad beside the house and holding the compressor and condenser coil. Inside, the air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home. These two units are the core of what a contractor places during an installation.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through the wall or floor. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. An outdoor disconnect box is mounted near the exterior unit to allow safe electrical shutoff at that location.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece fits the conditions of your specific house.

Severe Weather Events in Willacy County
Weather puts a measurable load on heating and cooling equipment, and that load varies by location. A heat pump sized and installed for local conditions holds up better over time than one specified for somewhere else.
