Sizing a heat pump for this part of Texas starts with the building, not the calendar. 41 severe weather events were recorded in Stonewall County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event in Stonewall County, not a standing pressure on every system running here. A heat pump that is struggling is almost certainly carrying the weight of age or an earlier install that was never quite right. A contractor quoting a replacement here will spend more time on load calculations and duct condition than on hardening a system against routine weather stress.
Ductwork laid down before heat pumps existed was sized and routed for a different kind of system, and what a contractor finds when they pull the registers often decides more about the job than anything on the equipment order. Half the homes in Stonewall County, Texas were built in 1971 or earlier (2020-2024 ACS 5-year). A house from that era may have flex runs added later, trunks too narrow for the static pressure a heat pump needs, or returns that were never meant to carry two-way conditioning load. The electrical panel tells a parallel story. A contractor quoting a heat pump installation here opens the house before they price the box.
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 exchange heat with the outside air. Inside, the air handler mounts in a closet, attic, or mechanical room and pushes conditioned air through the home. These two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system. A thermostat goes on an interior wall where it reads the temperature and signals the system to run. The contractor also installs the disconnect box near the outdoor unit and ties the new equipment into the existing supply and return air openings.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and how each piece gets positioned within it.
