Heat pumps have gone from a niche product to a common bid item for Denver-area furnace and air conditioner replacements. Before you compare quotes, here's what the equipment and installation cost, and what incentives still exist in 2026.
Installed cost by system type
From HomeGuide's heat pump guide (updated October 30, 2025):
| System | Typical installed cost |
|---|---|
| Air-source (ducted), average house | $10,000 – $25,000+ |
| Ductless, by number of zones | $2,000 – $17,000+ |
| Geothermal (ground-source) | $20,000 – $50,000+ |
HomeGuide's separate mini-split guide (updated October 8, 2025) puts a single-zone ductless system at $2,500 to $6,000.
Add-ons HomeGuide lists:
- New ductwork: $40 to $65 per linear foot, if the house doesn't have usable ducts.
- Permits: $50 to $300+, depending on location and scope.
Electrical upgrades are another common add-on. A heat pump may need a new circuit, and some older panels lack space or capacity.
Does a heat pump work in Denver winters?
HomeGuide notes that standard air-source heat pumps perform well above 25°F and that newer cold-climate models work effectively down to -13°F. Denver winters include cold snaps, so many installers pair a cold-climate heat pump with backup heat: electric resistance strips or the existing gas furnace (a "dual-fuel" or hybrid system). Ask each bidder:
- What the system's heating capacity is at 5°F and at your design temperature.
- What backup heat they propose and at what temperature it engages.
- Whether they did a room-by-room load calculation rather than matching the old furnace's size.
Incentives in 2026
Federal credit ended. The IRS says the Energy Efficient Home Improvement Credit (25C) applies to improvements made through December 31, 2025. Systems installed in 2026 don't qualify. Older cost guides that mention federal credits are out of date.
Colorado state credit. The Colorado Energy Office publishes 2026 amounts for the state heat pump tax credit, which registered contractors claim and partly pass on as a discount:
| Technology | 2026 credit | Minimum discount to customer |
|---|---|---|
| Air-source heat pump | $1,000 | $333 |
| Ground-source / water-source / combined | $2,000 | $667 |
| Heat pump water heater | $250 | $83 |
You don't claim this on your own taxes; ask your installer whether they're registered and how the discount appears on your invoice. See Colorado's heat pump tax credit explained.
Utility rebates. Xcel Energy offers heat pump rebates in Colorado. Municipal utility customers, such as in Longmont, may qualify for Efficiency Works incentives instead. In Boulder County, EnergySmart has income-qualified rebates. Check current terms before you sign, because requirements and amounts change.
An example budget
For a 2,000-square-foot house with good ducts, a ducted cold-climate air-source heat pump might fall in the middle or upper part of HomeGuide's $10,000 to $25,000 range. Subtract the minimum $333 state credit discount and any utility rebate you confirm in writing. If the house also needs an electrical panel upgrade or duct repairs, add those. This is an illustration, not a quote.
Operating costs
Whether a heat pump saves money compared with a gas furnace depends on electricity and gas rates, the system's efficiency and how much backup heat runs. Ask your installer for an operating cost estimate using your actual utility rates, and compare it against your past year's bills.
Water heaters count too
If your water heater is near the end of its life, a heat pump water heater is worth pricing at the same time. The Colorado Energy Office's 2026 state credit for heat pump water heaters is $250, with a minimum $83 discount to the customer from registered contractors. These units need space, airflow and a condensate drain, and they cool the room they sit in, which is usually fine in a basement mechanical room. Ask your plumber or HVAC contractor whether your space works.
Comparing bids
- Compare capacity at low temperatures, not just the nominal tonnage.
- Check efficiency ratings (SEER2 and HSPF2).
- Confirm who pulls the mechanical and electrical permits.
- Confirm which rebates and credits they've applied, in writing.
- Ask about warranty registration and maintenance.
