2026 Northern Arizona Insulation Rebates Guide

One of the most common questions we get from homeowners in Flagstaff, Prescott, Sedona, and Williams is some version of, "Is there any money out there to help pay for this?" It's a fair question, and the honest 2026 answer is more nuanced than a lot of insulation marketing makes it sound. This guide lays out what's actually available across Northern Arizona right now, what changed at the utility and federal level, and where to look before you assume a rebate applies to your project.

UniSource Energy Services: air sealing and insulation rebate

UniSource Energy Services (UES) provides natural gas across Coconino and Yavapai counties, including Flagstaff, Prescott, and Sedona. Through its published rebate program, UES offers 50% of installed cost up to $800 for combined air sealing and insulation work, for homes built in 2005 or earlier, completed through a UES-participating contractor. This is the single most broadly applicable rebate across our whole service area, since it isn't limited to Flagstaff city limits — it follows UES gas service territory.

• Rebate: 50% of installed cost, up to $800, for combined air sealing and insulation work.
• Eligibility: homes built in 2005 or earlier.
• Requirement: work completed through a UES-participating contractor.
• Coverage area: Coconino and Yavapai counties, including Flagstaff, Prescott, and Sedona.

City of Flagstaff Weatherization & Energy Rebate Program

The City of Flagstaff runs its own Home Weatherization and Energy Rebate Program on a fiscal-year funding cycle. The FY26-27 cycle runs July 2026 through June 2027, and offers up to $2,000 for a primary-source heat pump, or up to $1,500 for a non-primary heat pump, on a sliding income scale. This program is built primarily around heat pump upgrades, but it's explicitly designed to pair with insulation and weatherization work — a well-insulated, air-sealed home gets more out of a heat pump upgrade, and the same weatherization project that qualifies you for a UES rebate can be part of the same overall energy-improvement plan.

• Funding cycle: FY26-27, July 2026 through June 2027.
• Rebate: up to $2,000 for a primary-source heat pump; up to $1,500 for a non-primary heat pump.
• Structure: sliding income scale — the exact rebate amount depends on household income.
• Best used alongside insulation and air-sealing work, not as a standalone insulation rebate.

What Happened to APS Rebates

APS (Arizona Public Service) is the electric utility across most of this service area. In 2026, APS eliminated all of its residential energy-efficiency rebates, including insulation and weatherization incentives. If you've seen older marketing referencing an APS insulation rebate, treat it as out of date — we do not promise or advertise APS rebates for any 2026 insulation project, because that program no longer exists.

What Happened to the Federal Tax Credit

The federal 25C and 25D Energy Efficient Home Improvement Credits expired December 31, 2025. They are not available for insulation or weatherization work installed in 2026. If a contractor or a website promises a federal tax credit for a 2026 installation, that claim is out of date — plan your budget around the state and utility programs above instead, not a federal credit that no longer applies.

A Realistic Checklist Before You Assume a Rebate Applies

• Confirm whether your home was built in 2005 or earlier and whether UES provides your gas service — that determines eligibility for the 50%-up-to-$800 UES air sealing and insulation rebate.
• If you're inside Flagstaff city limits, ask about current FY26-27 Home Weatherization and Energy Rebate Program funding status and the sliding income scale before budgeting a specific dollar amount.
• Do not plan around an APS insulation rebate — APS eliminated all residential efficiency rebates in 2026.
• Do not plan around a federal 25C or 25D tax credit for a 2026 installation — those credits expired at the end of 2025.
• Get a written scope and cost estimate for the insulation work itself before applying to any program, since most rebate applications require project details up front.

Why This Still Matters Even Without a Guaranteed Rebate

Even setting incentives aside, under-insulated attics, walls, and crawlspaces cost Northern Arizona homeowners real money every winter, whether you're heating with natural gas in Flagstaff, propane in the rural county areas, or an electric heat pump anywhere in the service area. Rebates can meaningfully offset the upfront cost of fixing that, but the underlying case for the work — a warmer house, lower heating bills, fewer cold floors, less ice-dam risk — holds up on its own, with or without a check from a program.

We can't process rebate paperwork on a program's behalf, but we can give you an honest scope and cost estimate for the insulation work itself, which is usually the first thing any rebate program asks for anyway. Call 844-967-5247 or email josh@contractorschoiceagency.com and we'll walk your home in Flagstaff, Prescott, Sedona, or Williams and tell you where the insulation dollars — rebate or not — will do the most good.
