A contractor quoting a heat pump installation in Rio Grande County has to work out two things before settling on a unit: what the house needs at design temperature, and how much the heat pump's output shrinks when it gets there. Homes in Rio Grande County, CO run heat in every month of the year. At altitude and in cold winters, a heat pump loses capacity precisely when the house needs the most from it, so backup heat sizing is not a footnote on the quote. An installer who skips the full cold-weather load calculation leaves the homeowner with a system that leans on resistance strips through the hardest months.

Ductwork laid down for a furnace and an older cooling setup carries different static pressure, different trunk sizing, and different return configurations than a heat pump wants. Half the homes in Rio Grande County, Colorado were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump installation here has to assess that existing duct system before the equipment selection means much, because a unit spec'd to the house's square footage can still underperform if the duct network restricts the airflow the system runs on. The electrical service gets the same look: heat pumps draw differently than what many of these houses were originally wired to support.
What Gets Installed With a New Heat Pump

The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which do the core work of moving heat between the refrigerant and the outside air. Inside the house, the air handler mounts in a utility closet, basement, 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. A thermostat goes on an interior wall where it reads the home's temperature and signals the system to run. The condensate drain line carries moisture pulled from indoor air to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits your house.

Rio Grande County's climate puts real demands on heating and cooling equipment, and those demands are shaped by what the weather actually does here. A heat pump sized and installed for local conditions handles that workload better than one specified for somewhere else.
