The Honest 2026 Guide to Colorado HVAC Rebates & Tax Credits
2026 is the year the rebate landscape turned over. The federal 25C tax credit is gone — it expired December 31, 2025. The $8,000 income-qualified HEAR rebate closed for the entire Front Range in April. And Xcel cuts its heat pump rebate rates by roughly a third on October 1, 2026. Plenty of pages on the internet — and, frankly, plenty of contractors’ quotes — haven’t caught up.
This guide covers what is genuinely claimable today, what’s about to shrink, and what’s dead. For the at-a-glance status of every program, see our live rebate tracker — we keep it stamped with a verified date. We file every form for our customers; but it helps to know what’s real before anyone quotes you.
Program 1: Xcel Energy Rebates — Active, but Cut October 1
Xcel offers rebates for high-efficiency equipment installed in homes they serve. On August 5, 2026, Xcel notified trade partners that heat pump rebate rates drop on October 1, 2026 — this is the one deadline in this guide worth planning around.
Xcel heat pump rebate amounts: today vs. October 1
| Program | Through Sept 30 | From Oct 1 |
|---|---|---|
| Cold-climate heat pump | $2,250 / heating ton | $1,500 / heating ton |
| Standard heat pump (cooling) | $900 / cooling ton | $600 / cooling ton |
| Gas-heating customer bonus | 3× standard rate | 2× standard rate |
On a typical 3-ton cold-climate install, that’s roughly $6,750 today versus $4,500 after October 1 — a $2,250 difference on timing alone. Furnace and AC rebates are smaller and change on Xcel’s own schedule; we confirm the exact current number on every quote rather than publish a figure that can lag.
To Lock the Current Rate
Your system needs to be installed and invoiced by September 30, 2026, with the rebate application filed by October 15. A signed proposal doesn’t lock the rate — completion does. If your timeline can hit that window, the math is worth the push. If it can’t, the October rate is still real money, just less of it.
Program 2: Federal 25C Tax Credit — Expired
The federal 25C Energy Efficient Home Improvement Credit — up to $2,000 for a qualifying heat pump, $600 for a high-efficiency furnace or AC — was eliminated by Congress in the One Big Beautiful Bill Act, effective for anything not placed in service by December 31, 2025. It does not exist for a 2026 installation, no matter what a quote or an older article says.
If your system was installed and placed in service by that date, you may still claim it on your 2025 tax return. For any install happening now, leave this line off your math entirely — see our rebate tracker for the full list of what expired alongside it (the 25D solar/geothermal credit ended the same day).
Program 3: Colorado State Heat Pump Tax Credit — Active
Colorado’s own state credit (HB23-1272) is separate from the federal credit and is still running in 2026, at a lower rate than in past years by a schedule written into the statute:
- Air-source heat pump tax credit: $1,000 in 2026 (was $1,500 in 2024, $1,250 in 2025 — a scheduled step-down, not a surprise cut)
- Ground-source (geothermal) heat pump credit: $2,000
- Heat pump water heater credit: $250
The mechanics are different from most rebates: your contractor claims the credit from the state, and must be registered with the Colorado Energy Office to do it. The contractor is then required to pass at least a third of it to you as a line-item discount on the invoice — it should show up as its own line, not be folded silently into the total. We are a registered contractor and show this discount on every qualifying quote.
Program 4: HEAR (Formerly HEEHRA) — Closed for the Front Range
The Home Electrification and Appliance Rebate (HEAR), the federal income-qualified program often still called HEEHRA, offered up to $8,000 toward a heat pump for lower-income households. In Colorado it’s administered by region, and the news here isn’t good for our service area:
- Region 1 (Front Range — our entire service area): closed April 28, 2026. Applications submitted after April 27 are denied.
- Region 2 (outside the Front Range): still accepting contractor-initiated applications as of this writing.
If you’re in Wheat Ridge, Arvada, Denver, Lakewood, Westminster, Golden, or the foothills communities we serve, HEAR is not available to you right now regardless of income — and any quote counting on it is quoting a closed program. If that changes, we’ll update this section and the tracker.
One Program Worth Knowing About
Power Ahead Colorado opened June 29, 2026 for the Denver metro and offers $1,500 for cold-climate certified heat pumps. It’s funding-limited, meaning it can close early once the pool is committed — worth asking about at quote time rather than assuming it’ll still be open next month.
Real-World Stacking Examples (2026 Rules)
Example 1: 3-ton cold-climate heat pump, installed before September 30
Front Range home, $13,000 install, current Xcel gas-heating-customer bonus applies.
- Xcel rebate (3 tons × $2,250, gas-bonus eligible): $6,750
- Colorado state heat pump credit: $1,000 (contractor-claimed, passed through as a discount)
- Federal 25C credit: not available — expired 12/31/25
- HEAR/HEEHRA: not available — Region 1 closed 4/28/26
- Net cost: ~$5,250 — a $7,750 discount
Example 2: Same install, completed October 1 or later
- Xcel rebate (3 tons × $1,500, 2× bonus): $4,500
- Colorado state heat pump credit: $1,000
- Net cost: ~$7,500 — a $5,500 discount
Same equipment, same install — the $2,250 difference is purely a function of the calendar. This is the one place in this whole guide where timing changes the math by a meaningful amount.
Example 3: Furnace + AC replacement (no heat pump)
Front Range family replacing both. 96% AFUE furnace + 16 SEER2 AC at $12,000 combined.
- Xcel rebates: current published amounts, confirmed at quote time (see our price sheet for the base install cost)
- Federal tax credit: not available — expired 12/31/25
- Net cost is now closer to the sticker price than it was a year ago — which is exactly why the price itself matters more in 2026 than the rebate stack does.
Common Mistakes That Cost Homeowners Money in 2026
- Budgeting around the federal 25C credit. It’s gone. If a quote or a spreadsheet still has a “30% federal tax credit” line for a 2026 install, delete it.
- Assuming HEAR/HEEHRA is available. It closed for the entire Front Range in April 2026. Confirm your county’s region before counting on it.
- Missing the Xcel October 1 deadline on a heat pump install. If you’re close to ready, ask specifically whether completing by September 30 is realistic — it’s worth thousands.
- Installing non-qualifying equipment. Each active program has a specific equipment list. We confirm eligibility at quote time.
- Choosing a bid that hides the base price behind a rebate promise. Ask for the price with zero rebates applied first, then add whatever genuinely still qualifies.
How We Handle Rebate Paperwork
On every quote we produce, we confirm:
- Which of the currently active programs your specific install qualifies for
- The total rebate amount applied to your quote, shown as its own line — never folded into a single “after incentives” number
- What documentation we need at install time (Xcel account #, Colorado Energy Office registration, etc.)
- Whether your project timeline can realistically hit the September 30 Xcel deadline
For Xcel rebates, we file directly. For the Colorado state heat pump credit, our contractor registration lets us pass your share to you as a line-item discount at the time of install. We keep the rebate tracker current as programs change, so you’re never quoted against a number that already moved.
Frequently Asked Questions
Do heat pumps actually work below zero in Colorado?
Yes — modern cold-climate heat pumps (often called “ccHP” or units certified to the NEEP Cold Climate ASHP Specification) continue producing useful heat well below 0°F. They lose some capacity as temperatures drop, but they don’t “stop working” at any point relevant to Colorado.
How modern cold-climate heat pumps perform
- 47°F outdoor — rated capacity, ~300-400% efficient (COP 3-4)
- 17°F outdoor — ~85% of rated capacity, ~250% efficient (COP 2.5)
- 5°F outdoor — ~75% of rated capacity, ~200% efficient (COP 2.0)
- -13°F outdoor — ~60% of rated capacity, ~150% efficient (COP 1.5)
For perspective: a gas furnace runs at 80-98% efficient regardless of temperature. A heat pump at -13°F still runs at 150% efficient. The breakeven point on operating cost depends on local electric vs. gas rates, but in Xcel territory, most heat pumps are cheaper to operate than gas heating down to roughly -5°F.
The backup-strategy question
Dual-Fuel Is Often the Right Answer for Colorado
A “dual-fuel” system pairs a cold-climate heat pump with a small gas furnace or electric resistance backup. The heat pump handles roughly 90% of your heating hours (anything above ~15°F). The backup takes over only on the coldest nights. You get the efficiency and rebate stack of a heat pump with the absolute-coldest-night reassurance of a gas furnace.
Mountain installs (Evergreen, Conifer, Bailey)
At elevation above 7,000 feet, design temperatures drop into the -10°F to -20°F range. Heat pumps still work, but the dual-fuel configuration becomes almost mandatory for comfort during sustained cold snaps. We size mountain installs accordingly — typically with a 50/50 capacity split between the heat pump and the backup.
Do I need a permit for HVAC work in Wheat Ridge or Denver?
Yes — most major HVAC work in Wheat Ridge, Denver, Arvada, Lakewood, and other Front Range jurisdictions requires a permit and an inspection. Furnace replacement, AC installation, heat pump installation, gas line work, and ductwork modifications all typically require permits.
Work that typically requires a permit
- Furnace replacement or new installation
- AC condenser or coil replacement
- Heat pump installation (new or replacement)
- Mini-split installation (new or replacement)
- Gas line modifications
- Significant ductwork changes
- Boiler replacement
Work that usually doesn’t need a permit
- Filter changes
- Annual tune-ups and maintenance
- Minor repairs (capacitor, igniter, flame sensor, fan motor)
- Thermostat replacement
Why Permits Matter
Some contractors will offer to “skip the permit to save you the fee.” This is a bad deal:
- Voids manufacturer warranty on many equipment lines
- Issues at home sale — inspectors and appraisers find unpermitted work and it kills deals
- Voids your homeowner’s insurance coverage on any related claim
- Code violations — gas/venting/electrical issues caught at inspection get caught before they cause CO leaks or fires
- Illegal — the contractor and homeowner are both liable
What we do
We pull the appropriate mechanical permit for every major install — Wheat Ridge, Denver, Arvada, Lakewood, Jefferson County, and surrounding jurisdictions. Permit fees are included in our quotes (typically $100-$300 depending on jurisdiction and scope). We schedule the inspection and pass it the first time — that’s how a properly installed system works.
If you’re getting quotes and one contractor says “no permit needed” on a furnace or AC install — that’s a red flag. Get a different quote.
Do you offer financing on HVAC installations?
Yes — we work with several financing providers for HVAC installations. Most homeowners qualify for 0% promotional financing for 12-24 months, or fixed-rate longer-term financing (5-10 years) on larger projects like heat pump or whole-home installations.
Typical financing options available
- 0% promotional financing — 12, 18, or 24 months. Pay it off within the term, no interest.
- Fixed-rate installments — 5-10 year terms at competitive rates for larger projects
- Reduced-rate financing — special promos sometimes available on heat pump installs
- Combined with rebates — Xcel and Colorado state rebates can be applied to financed amounts
How to Stack Rebates with Financing
The smart play on a heat pump or high-efficiency system is to finance the install at 0% for 12-18 months, then apply your Xcel rebate check and Colorado state credit directly to the principal once they land. By the time the promo period ends, you’ve often paid off a meaningful chunk of the loan with rebate money. (Note: this no longer includes a federal tax credit — 25C expired December 31, 2025.) This is what most of our customers do.
What you need to qualify
- Standard credit application (soft pull, doesn’t affect score)
- Decision typically same-day, often within minutes
- Most installations under $15,000 are approved without issue for homeowners with average or better credit
We don’t push financing — we offer it because it makes good projects accessible. Cash is always welcome too, and we’ve never charged a “cash discount” or “credit card surcharge.” Our pricing is our pricing.

Does altitude really affect HVAC sizing in Colorado?
Yes, meaningfully. Combustion efficiency drops about 4% per 1,000 feet of elevation, and air density also drops — both factors that require altitude-adjusted sizing for proper HVAC performance in Colorado. Furnaces, AC units, and heat pumps all behave differently at altitude than at sea level.
The math in plain terms
- Denver (5,280 ft): ~21% efficiency derate vs. sea level on gas furnaces
- Wheat Ridge (5,440 ft): ~22% derate
- Evergreen (7,220 ft): ~29% derate
- Bailey (7,740 ft): ~31% derate
A furnace rated at 100,000 BTU at sea level only delivers about 79,000 BTU of useful output in Denver, and just 69,000 BTU in Evergreen. Air conditioners are similarly affected — thinner air carries less heat, so AC capacity also derates with altitude.
Why This Matters at Quote Time
A contractor who doesn’t account for altitude will routinely undersize systems for Colorado homes. The result: a furnace that barely keeps up at 0°F, an AC that can’t handle a 95°F afternoon, or a heat pump that needs more backup than necessary. Always ask: “What altitude derate did you apply in the sizing calculation?”
What we do differently
- Every Manual J load calculation includes altitude-adjusted combustion and air density
- For mountain installs (above 7,000 ft) we typically upsize by 10-15% to ensure capacity on the coldest nights
- We specify equipment with confirmed high-altitude orifice kits (required by code for some furnaces above 5,000 ft)
- We commission with combustion analysis at altitude — paper specs aren’t enough
Altitude is the most-overlooked factor in Colorado HVAC sizing. Don’t let a “we always go 80,000 BTU” quote land in your inbox without asking how altitude was factored in. Request a properly-sized quote →
How long does a furnace last at high altitude?
A well-maintained gas furnace in Colorado typically lasts 15 to 20 years — slightly shorter than the national average of 18-22 years. Altitude is a real factor: combustion efficiency drops about 4% for every 1,000 feet of elevation, so a furnace in Denver (5,280 ft) or Evergreen (7,200 ft) works harder than the same unit at sea level.
Colorado-specific factors that shorten furnace life
- Hard water in mountain areas (corrodes secondary heat exchangers on high-efficiency units)
- Heavy dust loads in dry summers — Colorado’s wind and lack of humidity pull dust through filters fast
- Short-cycling from aggressive thermostat setbacks during big diurnal swings
- Original ductwork in older homes — undersized returns starve the blower and overheat motors
- Marginal insulation in 1950s ranch homes forces the system to run harder
How to Add 3-5 Years of Life
Annual maintenance and a quality MERV 11-13 filter are the two cheapest things you can do. A $129 yearly tune-up that extends the unit’s life by even 2 years has paid for itself ten times over.
When to start planning replacement
If your furnace is 15+ years old and shows any of these signs, start getting quotes before it dies on the coldest night of the year:
- Rising gas bills year over year (efficiency declining)
- Yellow flame, soot, or carbon monoxide concerns
- Repeated repairs in the last 24 months
- Loud operation, uneven heating, or constant blower runtime
A planned replacement is always cheaper, calmer, and lets you lock in current Xcel and Colorado state rebates before they change. Learn more about furnace installation.
What HVAC rebates are available in Colorado?
2026 is the year the rebate picture changed. Two programs are genuinely active, one is being cut on a hard date, and two others that used to show up in these answers are gone. We file the paperwork on every install we do — but it helps to know what’s real before you budget around it. Full live status: our rebate tracker.
Active now — but Xcel is cut October 1
1. Xcel Energy Heat Pump Rebates (dropping ~1/3 on Oct 1, 2026)
- $2,250 per heating ton on cold-climate heat pumps through September 30 — drops to $1,500/ton after
- $900 per cooling ton on standard heat pumps through September 30 — drops to $600/ton after
- Gas-heating customers switching to a heat pump get a 3× bonus multiplier today, falling to 2× on October 1
- To lock today’s rate: installed and invoiced by Sept 30, application filed by Oct 15
2. Colorado State Heat Pump Tax Credit — active, no announced end date
- $1,000 for air-source heat pumps in 2026 (a scheduled step-down from $1,500 in 2024 and $1,250 in 2025)
- $2,000 for ground-source (geothermal) heat pumps; $250 for heat pump water heaters
- Claimed by our contractor registration and passed to you as a line-item discount — no income limits
3. Power Ahead Colorado — active, funding-limited
- $1,500 for cold-climate certified heat pumps in the Denver metro
- Opened June 29, 2026; these pools historically close early once committed
No longer available for a 2026 install
- Federal 25C tax credit (was up to $2,000 heat pump / $600 furnace or AC) — expired December 31, 2025
- HEAR / HEEHRA income-qualified rebate (was up to $8,000) — closed for the entire Front Range (our whole service area) on April 28, 2026; still open in Region 2 outside the Front Range
Total typical: ~$7,750 on a 3-ton cold-climate install (before Oct 1) — the honest number, with nothing in it that’s already expired.
Important notes
- Rebate amounts and deadlines move — this reflects programs verified as of the date on our tracker
- Not every piece of equipment qualifies — confirm before purchase
- If a quote you’re holding still lists the federal credit or HEAR/HEEHRA for a 2026 Front Range install, ask for the price with zero rebates — that’s the number that matters
