A contractor quoting a heat pump install in DeWitt County works from the site itself: the home's layout, its insulation, and the realistic cooling and heating load. 22 severe weather events were recorded in DeWitt County, Texas between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, so it does not drive the sizing math the way it would in harder-hit areas of the state. What decides a correct install is the accuracy of the load calculation and how cleanly the refrigerant lines, air handler, and electrical connections are run. A loose install that passes a quick visual check will bleed efficiency quietly for years, and no amount of weather allowance compensates for that.
Ductwork laid down for a gas furnace or window units was not designed around the airflow a heat pump needs to move efficiently through a house. Half the homes in DeWitt County, Texas were built in 1978 or earlier (2020-2024 ACS 5-year). That means a contractor pricing a heat pump installation here has to assess what the existing duct system will actually carry before the unit itself can be selected. If the ducts are undersized or the runs are poorly laid out, the equipment choice follows from fixing that first. Electrical service gets the same look, since a heat pump's draw has to be matched to what the panel can supply.
What a Heat Pump Installation Covers in Your Home
The outdoor unit sits on a concrete pad or wall bracket beside the house and holds the compressor and the main coil. The indoor air handler mounts in a utility closet, attic, or basement and moves conditioned air through the home. These two units are the core of what a contractor brings in and sets in place.
A refrigerant line set runs between the two units, passing through the wall to connect them. A thermostat goes on an interior wall where it can read the living space accurately. The disconnect box mounts near the outdoor unit and gives the system a dedicated shutoff point.
The drawing beside this text shows a typical layout, and a licensed contractor determines exactly what applies to your house and how each piece is positioned within it.
