Heat Pump Installation in Arvada

Thinner air means a heat pump's outdoor coil and indoor fan move less heat per cubic foot than the same unit at sea level. In NREL lab tests in nearby Golden, cold-climate equipment delivered about 5–7% less capacity than sea-level ratings. We size from a room-by-room Manual J using the Jefferson County design temperature of about 5°F, then check the manufacturer's capacity at 5°F, not the 47°F number on the brochure.

Denver-area weather spends few hours below 5°F (about 91 hours a year in NOAA's airport data), so a properly sized cold-climate unit does most of the work. Backup heat covers the rest.

A ducted heat pump needs a dedicated 240-volt circuit, and an air handler with electric backup strips needs another large one. Many 1970s homes here have 100-amp service that's already busy with a range, dryer and water heater. We check the panel during the estimate. Dual fuel usually avoids the big strip-heat circuit, which is one reason it's popular in older homes. If a panel upgrade is needed, HomeGuide's national range is $1,300–$1,600 for a 100-to-200-amp change, and that work is done by a licensed electrician under its own permit.

Arvada is a DRCOG member, so Power Ahead Colorado's $1,500 rebate applies to cold-climate air-source heat pumps in existing homes, as long as the contractor gets pre-approval before work starts. The Colorado heat pump tax credit is $1,000 in 2026, and at least $333 of it must show up as a discount on your invoice. Xcel Energy provides both gas and electricity here, so Xcel's heat pump rebates apply. Installers report Xcel lowered them on October 1, 2026, so confirm current amounts with Xcel. The federal 25C credit ended for equipment placed in service after December 31, 2025.

Be realistic about the bill. At recent Colorado prices, a high-efficiency gas furnace usually heats more cheaply than a heat pump. The heat pump's advantages are that it replaces your AC, cuts gas use and works best with a dual-fuel setup or off-peak rates. We walk through the numbers in heat pump vs. furnace in Colorado.

The city's Building Safety Division requires a residential mechanical permit, and only contractors holding an Arvada mechanical license can apply. Switching from an AC to a heat pump often changes heating capacity by 5% or more, and the city can then ask for a Manual J load calculation. We include one with every replacement. We pull the permit and schedule the final inspection.
