Sizing a heat pump for Erath County is a local question because the climate here puts a real but not relentless load on the equipment. 86 severe weather events were recorded in Erath County, Texas between 2015 and 2024. At that rate, severe weather is a recurring fact of life for any system running here, though not so heavy that it alone explains a compressor that died young or a unit that never kept up. A contractor quoting an installation has to establish whether the original system was sized and sealed correctly for this house, because those decisions shape how hard the equipment has to work every season it runs.
Ductwork laid in for a different generation of equipment is what a contractor runs into most often in Erath County. Half the homes in Erath County, Texas were built in 1991 or earlier (2020-2024 ACS 5-year). Ducts routed and sized for older systems frequently move the wrong volume of air for a heat pump, and the electrical service feeding the old equipment may not carry what a new unit draws. Those two questions, answered before anything else, are what shapes the scope and the cost of the job.
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 exchange heat with the outside air. Inside, the air handler mounts in a utility space, attic, or closet and moves conditioned air through the home. These two units are the core of what a contractor puts in place.
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 indoor temperature and signals both units. The condensate drain line runs from the air handler to a nearby drain, carrying away moisture pulled from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your specific home.
