Rebates and tax credits in Oklahoma

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 Oklahoma that names HRVs or ERVs. Your electric and gas utilities are still worth asking: search “[utility] HRV rebate” and “[utility] ERV rebate”.

Ventilation rebates that don’t name HRVs or ERVs

Usually ENERGY STAR bath or kitchen fans. Ask the program whether a balanced system qualifies before counting on it.

• Home rebates: bathroom ventilation fan

  Public Service Company of Oklahoma (PSO) · PSO residential customers

  $10

  'Must be ENERGY STAR Certified.' Bath fan only.

  Ventilation, not HRVs or ERVs by name

Federal home energy rebates

Federal money that Oklahoma 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.

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.

State tax credits

We didn’t find a Oklahoma 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 Oklahoma it’s run by Oklahoma Department of Commerce, through local nonprofit and Community Action Agency providers serving all 77 counties. Households at or below 200% of the poverty level; measures include insulation and air sealing, plus energy-related health and safety measures..

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

• PSO's $10 rebate is for an ENERGY STAR bath fan (ok5). No Oklahoma program was found that names HRVs or ERVs.
• Oklahoma Natural Gas lists only gas heating system rebates, with no insulation, air sealing or ventilation rebates (ok7).
• OG&E's older Home Energy Efficiency Program page (oge.com/wps/portal/oge/save-energy/residential/heep) opened but held no program details; use the Efficiency Programs page instead (ok3).
• State tax: the Oklahoma Tax Commission was not checked. A third-party site says no Oklahoma state tax credit or sales tax exemption applies to heat pumps (homeenergybasics.com, June 11, 2026; not official); other measures not addressed (ok8).
