A contractor quoting a heat pump install in Terry County has to work out what the local climate actually asks of the equipment before they can spec it correctly. 55 severe weather events were recorded in Terry County, Texas between 2015 and 2024. At that rate, severe weather is real but not relentless, and it does not drive every sizing decision a contractor makes here. What does drive those decisions is how well the unit is matched to the structure and how cleanly the install is executed. A heat pump undersized or poorly positioned will underperform regardless of how calm or rough the seasons run.

Ductwork laid in for older heating equipment carries a different set of assumptions than a heat pump requires, and in a county where much of the housing predates the era of modern forced-air design, that gap is where an installation quote either holds or changes. Half the homes in Terry County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). A contractor sizing a heat pump here has to open the supply and return runs before committing to a number, because the electrical service is a second variable that also traces back to what the house was originally built to handle. The panel may have been updated since; the ductwork is less likely to have been.
What a Heat Pump Installation Covers in Your Home

The outdoor unit sits on a pad beside the house and holds the compressor and the coil that pull heat from outside air. The indoor air handler mounts inside, usually in a closet, attic, or utility room, and it is the piece that moves conditioned air into the living space. Together these two units form the core of what a contractor installs.
A refrigerant line set runs between the two units, connecting them through the wall or the roof, and a condensate drain line carries moisture away from the air handler. A thermostat mounts on an interior wall and gives you control over the whole system from one point.
The drawing here shows a typical layout, and a licensed contractor determines exactly how each piece applies to your house.
