Heat Pump Installation in Columbine

Homes in Columbine Knolls, where the median year built is 1970, and the older parts of Columbine West and Columbine Hills sometimes still have 100-amp service. A heat pump outdoor unit needs a dedicated 240-volt circuit, and electric backup strips can add another 40 amps or more. If the panel is full, keeping your gas furnace as backup (dual fuel) usually makes more sense than an upgrade. If you want to go all-electric, HomeGuide's national range for a 100-to-200-amp upgrade is $1,300–$1,600, done by an electrician under a separate permit.

The area sits at about 5,542 feet. Jefferson County's ENERGY STAR design temperature is 5°F, and we size to that with a room-by-room Manual J. Equipment is chosen by its published output at 5°F, reduced for altitude; NREL measured about 5–7% less capacity at 5,860 feet than at sea level. Many 1960s and 1970s homes have had new windows and attic insulation since they were built, which lowers the load. That's why we calculate rather than match the old furnace size. Our sizing guide explains more.

Columbine is an unincorporated area, mostly in Jefferson County, with a small piece in Arapahoe County. Jefferson County Building Safety issues the mechanical permit for most addresses, with a separate electrical permit for the outdoor unit. Addresses in the Arapahoe portion go through Arapahoe County. We confirm which applies and pull the permits.

A utility directory lists Xcel Energy as the electric provider, so Xcel's heat pump rebates should apply. Installers report those changed on October 1, 2026; confirm current amounts with Xcel. Both Jefferson and Arapahoe counties are DRCOG members, so Power Ahead Colorado's $1,500 applies to cold-climate air-source heat pumps in existing homes, with contractor pre-approval before work starts. The Colorado credit is $1,000 in 2026, with at least $333 off the invoice. The federal 25C credit has ended. At current prices, a 95% furnace typically costs less to run per unit of heat, so the best payback usually comes from replacing an aging AC with a heat pump and keeping the furnace.
