Rebates and tax credits in Missouri

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

Money toward an HRV or ERVOther states
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 Missouri 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 Missouri 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.

Home Electrification and Appliance Rebates (also called HEEHR)

Not launched yetVentilation not confirmed

On June 17, 2026 the Missouri Department of Natural Resources said it is waiting on federal approval of its applications and the receipt of funds, and was seeking a contractor to design and run the programs. No launch date is given. Missouri calls this program HEEHR (High-Efficiency Electric Home Rebate). The documents give heat pumps as an example and do not list insulation, air sealing or ventilation.

Who qualifies: Low- to moderate-income households (no figures stated).

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.

  • Pay As You Save (PAYS) weatherization rebates

    Ameren Missouri · Ameren Missouri customers taking part in tier 4 of the PAYS program

    Ceiling/attic insulation $0.20 per sq. ft. (blown-in cellulose, starting at R-20 or below and raised to at least R-38). Air sealing $0.06 per sq. ft. (must achieve at least a 20% leakage reduction).

State tax credits

We didn’t find a Missouri 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, insulation and, where needed, ventilation at no cost to households that qualify by income. In Missouri it’s run by Missouri Department of Natural Resources, through 18 local weatherization agencies.

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

  • Missouri's June 2026 contractor solicitation says the program scope may change "because of the evolving guidance originating from USDOE." [s_mo_rfp]
  • In May 2026 the U.S. Department of Energy changed the rules for these federal rebates. States that had not launched must match the new rules before launching. [s_doe_pn262, s_naseo_faq]
