A contractor quoting a heat pump installation here has to settle the sizing question before anything else. Homes in Las Animas County, CO run heat about eight months a year, from October through May. Capacity on a heat pump drops as outdoor temperatures fall, so a unit that tests fine in mild weather can fall short when the house needs it most. An undersized system runs its compressor hard trying to close the gap, and back-up heat carries the load instead. Getting the load calculation right at the start is what keeps both the install cost and the operating cost honest.
Ductwork laid down for a gas furnace or a window unit follows different logic than what a heat pump installation needs: trunk sizes, return placement, and static pressure requirements can all run against each other when a contractor maps the old layout to a new system. Half the homes in Las Animas County, Colorado were built in 1972 or earlier (2020-2024 ACS 5-year). That share of the housing stock was ducted for something else, and what a contractor measures in the crawlspace or the attic decides whether the existing runs carry the new system or have to be reworked. Electrical service matters too, since a service panel sized for the original load on a house of that era often has little room for what a heat pump draws. The ductwork and the panel are what get priced first.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or wall bracket outside the house. It holds the compressor and the outdoor coil, and it is where the system pulls heat from or pushes heat to depending on the season. Inside the house, the air handler sits in a utility closet, basement, or attic and moves conditioned air through the home.
A refrigerant line set connects the outdoor unit to the air handler, running through the wall or crawlspace as a pair of insulated copper lines. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a supplemental electric resistance strip inside the air handler for the coldest stretches of winter.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

Extreme weather puts a direct load on heating and cooling equipment, shortening service life and widening the gap between an undersized system and one matched to local conditions. What the climate does in Las Animas County shapes what a heat pump installation here needs to handle.
