A contractor quoting a heat pump install in Caldwell County starts with what the site demands, not with a weather crisis. 55 severe weather events were recorded in Caldwell County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition the system fights year-round. What that means for installation work is that sizing decisions and equipment placement turn on the house itself, the ductwork, and the local heat load, not on hardening a system against constant atmospheric stress. A contractor who gets those fundamentals right at install is doing the job the county's conditions actually call for.
Ductwork sized and routed for a different era of equipment is what a contractor finds in a large share of Caldwell County homes. Half the homes in Caldwell County, Texas were built in 1991 or earlier (2020-2024 ACS 5-year). A heat pump moves air in patterns that older duct layouts were not designed around, so a contractor quoting an installation has to assess what is already in the walls and attic before the equipment choice settles anything. If the existing runs are undersized or poorly routed, the quote changes. The electrical service gets the same look, since a heat pump's draw has to be matched against what the panel actually carries.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad outside the house and holds the compressor and the heat exchanger coil that face the open air. The indoor air handler mounts inside, most often in a closet, attic, or utility room, and moves conditioned air through the home. These two units are the core of what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant between the two. A thermostat mounts on an interior wall and gives the homeowner control over the system. The condensate drain line runs from the air handler to a nearby drain, clearing moisture the coil pulls from indoor air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and how each piece is positioned within it.
