Colorado Window Rebate & Incentive Stack (2026): What's Replacing the Killed Federal Credit

We’re going to give it to you straight: the federal tax credit you may have heard about — the one paying up to $600/year for windows — ended on January 1, 2026. Congress killed it under the One Big Beautiful Bill (Public Law 119-21, July 4, 2025) for any windows placed in service after December 31, 2025. There’s no carryforward. There’s no replacement at the federal level.

If you delayed your project in 2025 hoping to claim the credit later, that window is closed.

The good news — and it’s actually pretty good news — is that the Colorado-specific stack of state, utility, and insurance incentives more than fills the gap for most homeowners. Here’s exactly what’s available, what to ask for, and how to combine programs so the numbers work.

What you’re working with in Colorado, 2026

Four real incentives plus a code change you should know about.

1. The Colorado Heat Pump Tax Credit — up to $1,000 (2026)

Colorado’s state-level heat pump tax credit is a pass-through discount applied at the time of purchase by a registered contractor. The amount tiered down across years:

• 2024: $1,500
• 2025: $1,250
• 2026: $1,000

It applies to heat pump installations directly, not windows. But here’s why it matters: a heat pump’s performance depends on your home’s envelope. The Colorado Energy Office actively encourages pairing heat pump installs with insulation, air sealing, and window upgrades because an undersized heat pump in a leaky house is a misery. Many of our customers are coordinating window replacement with a heat pump retrofit so the heat pump’s tax credit effectively offsets part of the window project.

2. Colorado Springs Utilities Rebates — up to $3,750 envelope, plus heat pump rebates

CSU dramatically boosted their 2025 rebate program and most of those increases carry into 2026. The big numbers:

• Insulation: up to $3,750 (a 66% increase over the prior year)
• Cold-climate heat pump: up to $3,000
• Heat pump water heater: up to $750
• ENERGY STAR furnace: up to $900 (an 80% increase)

Windows aren’t on the rebate list directly — CSU prioritizes whole-envelope work — but if you’re combining windows with insulation upgrades (which a lot of older Colorado Springs homes desperately need), the insulation rebate alone can offset thousands of the project. We coordinate with insulation contractors to help customers claim it.

For Pueblo and parts of unincorporated El Paso County served by Black Hills Energy, ask us about their current rebate menu — it changes annually.

3. Colorado HEAR Rebates — up to $14,000/household (Region 2 still open)

The Colorado Energy Office’s federally-funded Home Electrification & Appliance Rebates (HEAR) program offers up to $14,000 per household for electrification + envelope work, including insulation and air sealing alongside heat pump installs.

Status as of mid-2026:

• Region 1 (Front Range — Denver metro and most of Colorado Springs): closed April 28, 2026 after funds were exhausted
• Region 2 (Pueblo and outlying El Paso/Teller counties): still accepting applications until funds run out

If your home is in Region 2, this is a meaningful stack. We’ll help check eligibility during your consultation.

4. The Insurance Discount Most Homeowners Don’t Know About

This is the underused one. Most major Colorado homeowners insurance carriers offer a 5–15% premium discount for impact-rated or laminated-glass window installations. On the Colorado state-average premium of roughly $4,600/year, that’s $230 to $690 in annual savings that recurs every year — not a one-time credit.

The reason carriers love impact glass: hail. The Colorado Division of Insurance reported in February 2026 that hail risk is now responsible for 26 to 54 percent of homeowners insurance premiums in parts of the state. Carriers are actively rewarding mitigation, and impact-rated windows on west and south elevations are exactly the kind of mitigation they want to see.

We provide a Manufacturer Performance Statement with every Andersen install showing the impact rating, glass type, and certification. You forward that to your carrier and ask for the discount in writing. Most adjusters apply it within 30 days.

5. The Code Change You Need to Know About: HB 23-1161

This isn’t an incentive — it’s a requirement that affects every quote you’ll receive in 2026.

Colorado HB 23-1161 took effect January 1, 2026. Every residential window sold or installed in Colorado for buildings three stories or shorter must meet ENERGY STAR Version 7.0 Northern Zone criteria — generally U-factor ≤ 0.22 (or an equivalent-energy alternative). Builder-grade vinyl windows that don’t meet this threshold are no longer legal to install in your home. If a contractor quotes you a replacement window without proof of Northern Zone certification, walk away.

Every Andersen product we install meets or exceeds this threshold. The NFRC label on each window proves it, and we hand you that documentation as part of your project package.

What the math looks like for a real project

Let’s run a realistic Colorado Springs replacement: 12 windows, mid-range fiberglass-clad with Low-E4 SmartSun glazing.

That’s not the same as a clean $600 federal write-off. It’s better, because most of it isn’t a one-time credit — the insurance discount keeps paying you every year you own the home, and the rebates can stack with the financing program many of our customers use.

How to make sure you actually get all of it

Three things to ask any contractor, including us:

1. Will you provide an NFRC label and ENERGY STAR Version 7.0 Northern Zone certification on every window quoted? This is non-negotiable as of 2026.
2. Will you coordinate with my insulation contractor (or recommend one) so we can claim the CSU envelope rebate? A standalone window job won’t qualify on its own.
3. Will you provide a written Manufacturer Performance Statement I can submit to my insurance carrier for the impact-glass discount? This is the document carriers want — without it, the 5–15% discount conversation goes nowhere.

We answer yes to all three, automatically, on every quote.

What we’re seeing customers do in 2026

The smart play for most homeowners isn’t standalone window replacement. It’s a coordinated envelope project:

• Replace windows + add attic insulation = stack the CSU envelope rebate with the insurance discount
• Replace windows + heat pump = stack the CO heat pump tax credit with the insurance discount
• Replace windows + Region 2 HEAR (if you qualify) = stack everything

We help you sequence the work so the rebate paperwork lines up. It takes a little planning. The savings are real.

Let’s run your numbers

Tax credit and rebate programs change. Our job is to keep up with the latest so you don’t have to. We’ll walk through which incentives your project qualifies for, what documentation you need, and exactly how to claim everything — and you can stack the credits on top of our flexible financing options for a project that pencils out even better.
