Rebates and tax credits in Arizona

Federal tax credits ended for work done after 2025. What still helps pay for fresh air in Arizona is below, checked October 19, 2026. Programs change and money runs out, so check each one’s own page before you buy or sign.

HRV or ERV, in plain words
  • Fresh in, stale out Two fans swap stale indoor air for outdoor air all night, and can supply a closed bedroom.
  • Keeps much of the heat The two streams pass through a core, so winter air comes in warmed. An open window can’t.
  • HRV or ERV? HRV: heat recovery ventilator (heat). ERV: energy recovery ventilator (heat and some moisture).
  • Not a purifier A purifier cleans the air you have but brings none in, so CO2 stays put.

Measure first: you may not need one.HRV vs ERV guideUnits we’ve reviewed

Money toward an HRV or ERV

Programs that pay toward the unit itself. Some take the money off at the distributor, so ask whether an installer’s price already includes it.

We didn’t find a program in Arizona that names HRVs or ERVs. Your electric and gas utilities are still worth asking: search “[utility] HRV rebate” and “[utility] ERV rebate”.

Federal home energy rebates

Federal money that Arizona runs. HEAR has a category for “insulation, air sealing, and ventilation” worth up to $1,600 for households under 150% of area median income; each state decides what counts as ventilation. ENERGY STAR’s table for HEAR says this category requires ENERGY STAR certification, and ENERGY STAR’s U.S. criteria for ventilation cover fans, not HRVs or ERVs, so ask the program whether an HRV or ERV counts before relying on it. HOMES pays toward whole-home upgrades modeled to save energy.

OpenVentilation category

Efficiency Arizona, run by the Governor's Office of Resiliency, says "Applications are still being accepted, but must meet the new program guidelines," and lists "Insulation, Air Sealing, Ventilation: Up to $1,600." It doesn't name HRVs or ERVs. Reservations under the old rules closed August 28, 2026, and the new rules from September 1 no longer pay for switching fuels.

Who qualifies: As reported in the news: households below 80% of area median income (AMI) may get up to 100% of eligible costs, and households at 80% to 150% of AMI up to 50%, subject to each rebate's limit.

Air sealing and insulation

These programs are more common than ventilation rebates, and sealing a house is often what makes it need planned fresh air. If a program is sealing yours, ask whether it requires ventilation afterward and whether it pays for it.

  • Insulation Rebate and Duct Repair and Sealing Rebate

    APS (Arizona Public Service) · APS residential customers

    Insulation: $250. Duct repair and sealing: $250.

    No other conditions are stated on the rebates page. The same page says the Home Performance with ENERGY STAR checkup, smart thermostat and AC upgrade rebates are no longer available as of January 1, 2026; it gives no end date for the insulation and duct rebates.

    Ventilation not mentioned in what we read

  • SRP Insulation rebate (attic insulation with air sealing)

    SRP (Salt River Project) · SRP residential electric customers in single-family homes, apartments or condos (not new construction or mobile homes)

    Up to 75% of professionally installed attic insulation, up to $600, taken off the invoice

    Must use a participating SRP Insulation program contractor who is BPI-certified and licensed in Arizona. Attic only; existing insulation below R-19 brought to R-38. Insulation must be combined with air sealing unless documentation shows it is not needed. No ventilation requirement is mentioned.

State tax credits

We didn’t find a Arizona tax credit for ventilation, air sealing or insulation, and couldn’t confirm there is none.

Low-income help

The federal Weatherization Assistance Program can pay for air sealing and insulation for households that qualify by income. Your state energy office can say who runs it.

Before you sign

  1. Don’t start work yet. Many programs need pre-approval, a participating contractor or a test first, and work begun early often can’t qualify.
  2. Write down your electric and gas utilities. Rebates usually follow the utility, not the town.
  3. Read the conditions: a listed contractor, a qualifying model, your heating fuel, income limits, and install and claim deadlines.
  4. Ask each installer whether any discount is already in their price, and who files the paperwork.
  5. Get it in writing: each rebate, who applies for it, and what happens to the price if it’s denied.

Worth knowing

  • Efficiency Arizona changed for the new federal rules. News reports said gas-to-electric swaps had to apply by August 1, 2026, August 28, 2026 was the last day to reserve a rebate under the old rules, and from September 1, 2026 there are no rebates for switching from gas to electric and insulation and air sealing may be required with heat pump projects. Reservations made in time could still be installed and paid later. (s3, s4)
  • Under guidelines revised in September 2026, a home with gas heat can replace only the air conditioner with a qualifying heat pump and keep the gas furnace; there is no rebate for removing or replacing the gas heater. (s5)
  • Two older state pages are out of date: one says rebates were to begin in 2024, and an undated news page says Efficiency Arizona was paused during a federal funding freeze. Later news reports describe the program running in 2025 and 2026. (s1, s2, s3)
  • Southwest Gas's 2026 Arizona residential rebates cover low-flow showerheads, clothes washers and ENERGY STAR windows ($1.00 per square foot, natural gas heat required). No insulation, air sealing or ventilation rebates are listed. (s8, s9)
