Colorado homeowners can access meaningful financial incentives for insulation and air sealing upgrades — from utility rebates to federal tax credits. The challenge is that most programs have different eligibility rules, different submission processes, and are administered by different organizations. This guide consolidates everything you need to know in one place.
Level Up Insulation Co. is a registered Xcel Energy rebate partner. We handle all rebate paperwork for projects we install — you don’t need to navigate this alone.
Xcel Energy Insulation Rebates (Denver Metro and Northern Colorado)
Xcel Energy is the largest utility provider in the Denver metro, Boulder, Fort Collins, and northern Colorado. Their residential insulation rebate program offers:
Attic insulation upgrade to R-49 or above
up to $600 rebate for qualifying projects
Air sealing combined with insulation
additional $150–$300 rebate (varies by project type)
Whole-home weatherization packages
up to $1,500 for comprehensive air sealing and insulation projects
Income-qualified households
rebates of 80–100% of project costs through Colorado Energy Assistance
To qualify for Xcel Energy rebates, the work must be performed by a registered Xcel rebate partner using approved materials, and the home must be an Xcel-served residential property. Pre-approval is required for some program tiers — we handle this step before the project starts, not after.
Black Hills Energy Insulation Rebates (Southern Colorado)
Black Hills Energy serves customers in Colorado Springs and southern Colorado. Their residential insulation rebates include:
Attic insulation
rebates based on installed R-value improvement (typically $0.10–$0.20 per square foot)
Air sealing
additional rebate when combined with insulation installation
Black Hills rebate amounts and structures change periodically. Level Up Insulation confirms current rebate availability for Black Hills service area customers during the assessment.

Fort Collins Utilities (FCU) offers some of the most generous rebates available to Colorado homeowners:
Attic insulation to R-49: up to $0.15 per square foot
Air sealing: flat rebate of $150–$300 when combined with insulation
Combining FCU rebates with Xcel rebates is not possible (you have one utility), but FCU amounts can be higher
For blown-in insulation in Fort Collins customers, FCU rebate stacking with federal tax credits can cover 25–40% of project costs in qualifying homes.
Federal Tax Credits for Insulation (IRS Section 25C)
The Inflation Reduction Act extended and expanded the residential energy efficiency tax credit through 2032. For insulation:
30% tax credit on the cost of qualifying insulation materials (not labor) up to $1,200 per year
Materials must meet applicable IECC standards — which blown-in fiberglass and cellulose and spray foam all do in qualifying applications
The credit applies to the material cost only, not installation labor
There is no income limit for this credit
Important: this is a tax credit, not a rebate — it reduces your federal income tax liability. You need to have federal tax liability to benefit. Consult a tax professional for your specific situation. IRS Form 5695 is used to claim it.
How to Stack Multiple Incentives
The most valuable approach for Colorado homeowners is stacking available incentives. A typical Denver-area attic insulation and air sealing project might look like:
Project cost: $4,200 for attic air sealing + blown-in insulation to R-60
Xcel Energy rebate: $600 credit applied to invoice
Federal tax credit (30% of material cost, ~$1,200 on this project): $1,200 off taxes
Net cost after incentives: approximately $2,400
That’s nearly 43% of the project cost recovered through incentives. This math is why properly timed attic insulation in Colorado and attic sealing in Colorado projects often deliver payback periods of 4–7 years rather than 10–15.
Rebates for Specific Services
Spray foam insulation in Colorado — Xcel rebates apply to spray foam when used for air sealing in qualifying applications. Full spray foam attic replacements may qualify under whole-home weatherization tiers.
Blown-in insulation in Colorado — the most commonly rebated service through Xcel Energy. Straightforward qualification for attic insulation upgrades to R-49 or above.
Crawl space encapsulation in Colorado — rebates vary by program. Some Xcel tiers include crawl space air sealing as part of comprehensive weatherization packages.
Attic sealing in Colorado — qualifies for Xcel rebates when performed in combination with insulation installation.
Do I need to apply for rebates before the work is done?
For most Xcel Energy rebate tiers: yes, pre-approval is required for larger rebate amounts. Level Up Insulation handles this step as part of every project — we confirm pre-approval before scheduling your installation.
How long does it take to receive a rebate?
Xcel Energy rebates typically process within 4–8 weeks of project completion and documentation submission. We submit everything on your behalf.
What if I've already had insulation installed by another contractor?
Retroactive rebate applications are generally not available for completed projects. Rebates require pre-approval or registration before the work is performed. If you’re planning future work, contact us before scheduling.
