Sizing a heat pump for this county starts with how cold it actually gets in January and February, not just how long the heating season runs. Homes in San Miguel County, NM run heat about eight months a year, from October through May. A unit sized to the average load handles the shoulder months fine but loses capacity right when outdoor temperatures bottom out, and the backup electric resistance strips carry the slack. A contractor has to establish the design-temperature load first, before any equipment gets specified, because that number is what decides whether the heat pump does the work or the strips do.
Ductwork and electrical panels in older houses were built around whatever heated and cooled them at the time, and a heat pump draws differently from what most of that stock was wired for. Half the homes in San Miguel County, New Mexico were built in 1979 or earlier (2020-2024 ACS 5-year). That puts the service panel at the center of what a contractor has to assess before the equipment question even opens. If the panel cannot carry the new load, the installation scope changes, and the quote changes with it.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first. It sits on a pad outside 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, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides of the system. A thermostat goes on an interior wall and gives the homeowner control over the whole setup. Both pieces are part of what a contractor puts in during a full installation.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific house.
