A contractor quoting a heat pump installation in Eddy County has to size the system against a real heating load, not a rule of thumb, because a heat pump's capacity drops as outdoor temperatures fall and backup resistance heat fills whatever gap the compressor cannot cover. Homes in Eddy County, NM run heat about five months a year, from November through March. An undersized compressor leans on that backup heat element through the coldest part of the season, which is the expensive part of the operating cycle. The load calculation a contractor runs before the quote determines where that line sits, and an installer who skips it shifts the cost from the invoice to the electric meter.
Ductwork laid down for an older central system carries specific dimensions, turns, and trunk lines that a heat pump does not automatically match. Half the homes in Eddy County, New Mexico were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump today has to check whether that existing duct network moves enough air for the new equipment's output, and whether the home's electrical service can carry the load the new unit draws. Those are not formalities. If the ducts are undersized for the distribution pattern a heat pump requires, the installation scope grows before the unit is ever ordered.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the outdoor coil, which together do the heavy lifting of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing that a contractor routes along the exterior or through the structure. The thermostat goes on an interior wall and gives the system its instructions, telling the equipment when to run and at what temperature to hold the house.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece applies to your home.
