2026 Arizona Insulation Rebates & Incentives Guide: Efficiency Arizona HEAR, UniSource, and What Changed After the Federal Tax Credit Expired

Rebate and tax-credit information for home insulation changes fast, and a lot of what's floating around online — including on some contractor websites — is out of date. If you're planning an insulation project in Show Low or the wider White Mountains for 2026, here's the current, honest picture: what's actually available, what expired, and what to verify before you count on a specific number.

The federal 25C tax credit has expired — don't count on it

For several years, the federal Energy Efficient Home Improvement Credit (Section 25C) let homeowners claim 30% of qualifying insulation and air-sealing material costs, up to annual limits, as a tax credit. That credit expired after December 31, 2025. If a contractor, article, or ad tells you a federal tax credit applies to your 2026 insulation project, that information is out of date — it does not currently apply. We'd rather tell you this plainly than let outdated marketing set an expectation we can't deliver on.

What is actually available: the Efficiency Arizona HEAR program

The statewide Efficiency Arizona HEAR (Home Energy Assistance Rebate) program is the real, current rebate path for a 2026 insulation project. It's a federally funded program administered at the state level, offering home energy upgrade rebates of up to $14,000 depending on household income and project scope. Within that program, insulation, air sealing, and ventilation work is specifically eligible, with a rebate ceiling of up to $1,600 for that category of work. Funding is income-tiered: lower-income households can have a larger share of eligible costs covered, while middle-income households typically see a partial-coverage rebate rather than full coverage.

A genuinely useful feature of the HEAR program is that it's explicitly designed to stack with UniSource Energy Services utility rebate programs, rather than forcing you to choose one or the other. That means a well-planned project can potentially draw on both a state-administered HEAR rebate and a UniSource program at the same time.

UniSource Energy Services

UniSource Energy Services provides natural gas service to Navajo County, including a local Show Low office — a meaningful local detail, since Show Low is not a propane-only market the way some more rural White Mountains communities are. As a regulated utility, UniSource periodically runs efficiency and weatherization-related programs; the HEAR program's design assumes these can stack with state funding. Ask directly about current UniSource programs when you're planning a project, since program availability shifts.

Navopache Electric Cooperative

Navopache Electric Cooperative is the electric provider serving Show Low and much of the surrounding region. We were not able to independently verify a specific dollar-amount insulation or weatherization rebate directly from Navopache, so we won't invent a figure here — that would be exactly the kind of unreliable claim this guide is trying to correct. What we can say confidently: it's worth asking Navopache directly about any current energy-audit or weatherization-assistance programs, since member-cooperative offerings do change, and there's a reasonable chance that broader regional weatherization-assistance programs serving Navopache's territory extend to Show Low members as well.

Why this matters more than it might seem

Insulation upgrades are one of the highest-return home improvements available almost anywhere, but that return gets meaningfully better when part of the cost is offset by a rebate you actually qualify for and correctly apply to. The mistake we see most often isn't homeowners missing rebates entirely — it's homeowners planning a budget around outdated information (an expired federal credit, a rebate amount from a different state or program, or a figure that was accurate a year ago but has since changed) and then feeling misled when the real number comes in different. Getting current, accurate information before you budget is the whole point of this guide.

How to make sure your project actually qualifies

A few practical steps protect you here. First, confirm the current Efficiency Arizona HEAR program status and your household's income tier before assuming a specific rebate amount — program funding and windows can change. Second, ask any contractor you're considering to show you where their rebate claims come from, rather than taking a marketing number at face value. Third, keep documentation of your home's insulation condition before and after the work — most rebate programs require this, and a contractor who builds it into the project (rather than treating it as an afterthought) makes the difference between a smooth rebate claim and a denied one.

The honest bottom line for 2026

If you're planning a Show Low insulation project this year: the federal tax credit is gone, don't budget around it. The Efficiency Arizona HEAR program is real and currently active, with insulation and air sealing specifically eligible and funding tiered by income — verify current status before finalizing numbers. UniSource programs may offer additional stacking value, and it's worth asking Navopache about weatherization assistance directly. We build every quote around current, verified program information — not outdated marketing claims — and we'll walk you through exactly what applies to your specific project.
