Sizing a heat pump for this area starts with what the local climate actually demands, and that picture includes how often severe weather moves through. 60 severe weather events were recorded in Uvalde County, Texas between 2015 and 2024. At that rate, severe weather is an event here, not a standing operating condition, which means a contractor quoting a new install is not building around storm load as a primary variable. Age of existing equipment, duct quality, and how well the original install was matched to the structure carry more weight in what the contractor specifies and prices.

Ductwork laid down for a different generation of equipment is what a contractor is opening walls to assess on many jobs here. Half the homes in Uvalde County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). Heat pumps move air at volumes and static pressures that older duct layouts were not designed around, so whether the existing runs are sized right and sealed well enough is the question that shapes the scope before the unit itself is even priced. Electrical service is the other variable, since the panel has to support the load the new equipment draws.
What a Heat Pump Installation Covers

The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home. These two units are what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two and carrying refrigerant back and forth. A thermostat goes on an interior wall and gives the homeowner control over the system. Both the line set and the thermostat are part of what gets placed during the installation.
The drawing shows the typical layout of these components, and a licensed contractor determines what applies to your specific house.

Severe Weather Events in Uvalde County
Uvalde County weather puts real demands on heating and cooling equipment over time. A heat pump sized and installed for local conditions handles those demands differently than one spec'd for somewhere else.
