Heat Pump Installation Across the Denver Metro

As of September 2026, the Arvada residential mechanical permit page lists heat pumps among the new and replacement appliances that need an approved, issued permit before any work begins. Read that twice. If a crew wants to start pulling your furnace before anyone has mentioned a permit, stop them and ask. The Arvada heat pump installation page covers the rest, including what to ask your installer about who files the permit.

Then you're in the Mile High City. Several local rules apply at the city level: Denver licenses mechanical contractors and requires permits for mechanical work. Colorado does not have a statewide HVAC or mechanical contractor license, so the rules really do change from one city line to the next. The Denver permit portal also reminds people to check that their parcel is actually inside the city, which sounds obvious until you remember that a mailing address and a city boundary aren't always the same thing. Check first.

The housing stock here is older than in most suburbs. Per the Census ACS 2024 5-year estimates, the median Denver home was built in 1975, and 16.9% of the 359,581 housing units in the city were built in 1939 or earlier. That's a lot of old houses. Many have been through a few heating systems already, and some have ductwork nobody has looked at in decades.

The city runs a group-buy program for qualifying Denver homeowners. Its process gives you an initial estimate, followed by an installer visit to the home and then a final quote. That program isn't us, and we can't get you into it. Still, the order of steps makes a useful point: a real number comes from someone who has seen your house.

What a good installer looks at

• A room-by-room load calculation (Manual J) that works out how much heating and cooling the house needs, instead of just copying the size of the old unit.
• A look at your ducts. A ducted heat pump uses the existing ducts, while a ductless system mounts indoor heads instead.
• A check of the electrical panel, covering its capacity and whether you'll need a new circuit.
• A plan for where the outdoor unit goes, since snow, drainage and clearance all matter, along with how the refrigerant lines get routed and where the condensate drains.
• A decision about all-electric versus dual-fuel. An all-electric setup relies on the heat pump alone. A dual-fuel setup keeps your gas furnace as backup. Cold-climate models are built to keep heating in sub-zero weather, and your installer can tell you which setup fits your house.

The money part, briefly

These points apply for 2026:

• Colorado's heat pump tax credit gives air-source installs a minimum customer discount of $333, and it shows up on your invoice as a line labeled "State of Colorado Heat Pump Discount." Only a state-registered contractor can apply it. So ask whether your installer is on the registered list.
• If Xcel is your utility, the bonus rebate tier requires an invoice dated in 2026, per Xcel's 2026 rebate summary effective Oct. 1, 2026.
• The federal 25C credit only covered improvements made through Dec. 31, 2025. Heat pumps installed in 2026 don't qualify. Check tax questions with a tax professional.

Confirm your eligibility with your utility or installer. The Denver heat pump rebates guide goes into more detail.
