Holy Cross Energy Air Sealing and Insulation Rebate

This rebate from Holy Cross Energy helps members make their homes more energy-efficient by covering costs for professional air sealing and insulation upgrades. It’s a great way to cut energy waste, especially in electrically heated homes common in their Western Colorado service area.

Overview

Holy Cross Energy, a member-owned electric cooperative, offers straightforward rebates to encourage efficiency upgrades.

• Provider: Holy Cross Energy
• Eligible Areas: Homes in their service territory – Eagle, Pitkin, Garfield, Mesa, and Gunnison counties in Colorado
• Rebate Amounts: Up to $1,500 for air sealing + $1,500 for insulation (standard members); doubles to $3,000 each for income-qualified households (under 150% of area median income)
• Covered Improvements: Air sealing (attic, crawlspace, exterior walls) and insulation in key spots like unfinished attics (to min. R-60), exterior walls/foundation (to min. R-19), floors over garages/crawlspaces (to min. R-30), and crawlspace walls (to min. R-19)
• Expiration: Applies to projects in 2026 (through December 31, 2026)

How It Helps You

Air sealing and adding insulation can seal up drafts and keep conditioned air where it belongs. The EPA estimates these upgrades often save homeowners 15% on heating and cooling costs – or about 11% on total energy bills. In Colorado’s variable climate, this means more consistent indoor comfort year-round, lower monthly bills, and reduced strain on your heating system.

Pros

• Significant upfront savings to offset project costs
• Potential to stack with federal Inflation Reduction Act credits (like the 25C tax credit for insulation) or local Energy Smart Colorado partner rebates
• Environmental benefits: lower energy use means a reduced carbon footprint

Cons

• Requires professional work and paperwork (like blower door tests for air sealing)
• Limited to electrically heated homes

Eligibility and Application

• Key Requirements:

Real-World Examples

• A homeowner in Eagle County with an electrically heated home adds attic insulation to R-60 and seals major leaks. They could receive $1,500 back for insulation and $1,500 for air sealing – plus ongoing savings of hundreds per year on winter heating bills.
• An income-qualified family in Garfield County upgrades walls and floors. They get $3,000 per measure, cutting payback time significantly while enjoying a warmer, draft-free home.
