Why Most Utah Homeowners Only Capture Part of the Savings
A heat pump installation in northern Utah typically runs $7,000 to $12,000 depending on tonnage, equipment tier, and whether existing ductwork needs modification. That price is what stops most homeowners before they ever get a quote. What those same homeowners rarely know is that three separate incentive programs — one from their electric utility, one from their gas utility, and one from the federal government — can be layered together.
Done correctly, the stacking approach reduces a typical $8,000 installation to roughly $3,100 out of pocket. That math changes the conversation entirely. This guide walks through each program in detail: who qualifies, how much you can get, and how to make sure no money gets left behind.
Program 1: Rocky Mountain Power Wattsmart Home Rebates
Rocky Mountain Power operates the Wattsmart program for residential customers in Utah. It is the largest single source of upfront rebates for heat pump installations, and it has a tiered structure that rewards higher-efficiency cold-climate equipment.
Base Rebate: $200 per Ton
The base Wattsmart rebate for a qualifying heat pump is $200 per ton of capacity. A typical 2-ton system for a 1,200–1,600 sq ft Utah home earns $400. A 3-ton system covering 1,800–2,400 sq ft earns $600. A 4-ton system for a larger home earns $800. These base amounts require the installed equipment to meet minimum ENERGY STAR certification and efficiency thresholds.
Cold-Climate Bonus: Up to $1,500 Additional
This is where most homeowners — and many contractors — miss out. Rocky Mountain Power offers a separate cold-climate bonus for heat pumps rated at HSPF2 (Heating Seasonal Performance Factor, second edition) of 7.5 or higher. Cold-climate rated units are designed to maintain their full heating capacity even when outdoor temperatures drop below 5°F, which directly addresses the most common objection to heat pumps in Utah.
The bonus rebate for cold-climate qualifying units can reach $1,500, bringing the total Wattsmart rebate to $2,000–$3,000 for a qualifying 3-ton cold-climate installation. Most current Daikin models — including the Aurora and Daikin Fit lines — meet the HSPF2 ≥ 7.5 threshold and qualify for this enhanced tier.
Eligibility Requirements
- You must be an active Rocky Mountain Power residential customer in Utah
- The rebate is highest when replacing electric resistance heat (baseboard heaters, electric furnace) or adding cooling to a heating-only home
- Equipment must be installed by a licensed Utah HVAC contractor
- The system must be permanently installed — window units and portable systems do not qualify
How to Apply
Wattsmart rebates can be submitted two ways: the installing contractor submits the application on your behalf (the most common route, and how Salmon HVAC handles it), or you submit directly through the Rocky Mountain Power customer portal at rockymountainpower.net. Contractor-submitted applications are typically processed within 6–8 weeks of installation completion.
Note: Rebate amounts shown are as of March 2026. Rocky Mountain Power updates program tiers annually. Verify current amounts at rockymountainpower.net/wattsmart before finalizing your project budget.
Program 2: Dominion Energy ThermWise Incentives
Dominion Energy serves natural gas customers across northern Utah, including most of Davis County, Weber County, and Salt Lake County. Their ThermWise program is primarily focused on gas efficiency, but it includes meaningful incentives for dual-fuel heat pump systems — configurations where a heat pump handles the majority of heating days and a gas furnace provides backup capacity during the coldest stretches.
Dual-Fuel Heat Pump Rebate: $300–$500
A dual-fuel system pairs an electric heat pump (outdoor unit) with a gas furnace (indoor unit). The heat pump does most of the work — typically everything above 0°F to -5°F — while the gas furnace activates as a backup when efficiency tips in favor of combustion heat. This configuration is Dominion Energy's recommended approach for Utah's climate, and ThermWise offers a $300–$500 rebate for qualifying dual-fuel installations.
Eligibility requires that you are an active Dominion Energy gas customer and that the installed system meets minimum efficiency ratings for both the heat pump and the furnace components.
Smart Thermostat Rebate: $50–$75
ThermWise also offers a $50–$75 rebate on qualifying smart thermostats. This is typically stackable on the same project as a heat pump installation. If you are replacing your existing thermostat as part of the heat pump installation — which is almost always required — this rebate is easy incremental savings with minimal paperwork.
Note: ThermWise rebate amounts and eligible equipment lists are updated periodically. Verify current amounts at dominionenergy.com/utah before your installation date.
Program 3: Federal IRA Section 25C Tax Credit
The Inflation Reduction Act of 2022 created — and through 2032, extended — a federal tax credit for qualifying home energy improvements. Section 25C covers heat pumps specifically, and it is the most valuable single incentive for most Utah households because it does not interact with utility rebates. You can claim the full utility rebate and the full federal tax credit on the same installation.
How Much: 30% of Cost, Up to $2,000
The 25C credit equals 30% of the combined equipment and installation cost for a qualifying heat pump. The credit is capped at $2,000 per tax year. On an $8,000 installation, 30% equals $2,400 — but the cap limits your credit to $2,000. On a $6,500 installation, 30% equals $1,950, which falls under the cap, so you capture the full 30%.
This is a tax credit, not a deduction. It reduces your federal income tax liability dollar for dollar. If your tax bill for 2026 is $4,500 and you claim a $2,000 heat pump credit, your tax bill drops to $2,500. If your tax liability is less than $2,000, you capture only what you owe — this credit is non-refundable and does not carry forward under current law.
Eligibility Requirements
- The heat pump must be ENERGY STAR certified (all current Daikin models qualify)
- You must own the home — renters cannot claim this credit
- The home must be your primary residence in the United States
- New construction does not qualify — this credit is for improvements to existing homes
- The credit does not expire until December 31, 2032
How to Claim It
Claim the 25C credit on IRS Form 5695 (Residential Energy Credits) when you file your federal taxes for the year the installation is completed. Save your contractor invoice showing itemized equipment and labor costs. The form is straightforward — you enter the total cost and the credit is calculated automatically. No pre-approval, no utility involvement, no coordination required.
Stacking All Three: The Real Math
Here is a realistic example using a 3-ton Daikin Aurora cold-climate heat pump installation in Davis County — a dual-fuel system paired with a new 80% AFUE gas furnace:
Sample Installation: Davis County, Dual-Fuel System
| Gross installation cost | $8,000 |
| Wattsmart rebate (cold-climate, 3-ton) | - $2,500 |
| ThermWise dual-fuel rebate | - $400 |
| IRA 25C federal tax credit | - $2,000 |
| Net cost after all incentives | $3,100 |
The $2,500 Wattsmart rebate arrives as a check within 6–8 weeks of installation. The ThermWise rebate is submitted separately and arrives within 4–6 weeks. The $2,000 tax credit reduces your federal tax liability when you file — it is not upfront cash, but it is real money.
Total incentives: $4,900 on an $8,000 installation. That is 61% of the gross cost recovered through programs that any qualifying Utah homeowner can access. The difference between $8,000 and $3,100 is entirely a function of knowing about the programs and submitting the right paperwork.
Which Heat Pump Models Qualify
Not every heat pump qualifies for every program. Here is what to look for:
ENERGY STAR Certification (Required for Federal Credit)
All ENERGY STAR certified heat pumps meet minimum efficiency standards set by the EPA. For split-system heat pumps, ENERGY STAR requires SEER2 ≥ 15.2 for 2-stage or variable-speed units, and a minimum HSPF2 of 7.5. Most current heat pump models from major manufacturers — including all current Daikin residential models — carry ENERGY STAR certification. Check the ENERGY STAR product finder at energystar.gov if you are evaluating a specific model.
Cold-Climate Rating (Required for Wattsmart Bonus)
The Wattsmart cold-climate bonus requires HSPF2 ≥ 7.5 and, in most cases, documentation that the unit maintains rated heating capacity at low outdoor temperatures. Daikin's cold-climate product line includes:
- Daikin Aurora series — rated to -13°F, HSPF2 up to 10.5, qualifies for the maximum Wattsmart cold-climate bonus
- Daikin Fit — side-discharge design for tight spaces, rated to -13°F, HSPF2 up to 10.0
- Daikin DX20VC — variable-speed inverter compressor, HSPF2 up to 10.5, strong cold-weather performance
When Salmon HVAC quotes a heat pump installation, we identify which programs the proposed equipment qualifies for and include that in the written estimate. There are no surprises at rebate submission time.
Salmon HVAC Handles the Rebate Paperwork
Wattsmart rebate applications require contractor license numbers, equipment serial numbers, installation date verification, and utility account information. Dominion Energy ThermWise has a separate application process. We manage both submissions on behalf of our customers — you receive the rebate checks directly, but we handle the filing. The federal tax credit documentation (a copy of your itemized invoice) is something you provide to your accountant or enter into your tax software directly.
Step-by-Step Application Process
- Get a written quote that identifies the specific model, tonnage, HSPF2 rating, and whether it qualifies for Wattsmart cold-climate bonus. Ask your contractor to confirm this in writing before you sign.
- Confirm your utility accounts. Wattsmart requires you to be an RMP customer. ThermWise requires you to be a Dominion Energy customer. If you only have one utility or the other, you will only access those programs.
- Schedule the installation. Both Wattsmart and ThermWise rebates are submitted post-installation — the equipment must be installed and functional before the application is submitted.
- Contractor submits utility rebates. Salmon HVAC submits both the RMP Wattsmart and the Dominion ThermWise applications within a few days of installation completion. We provide you copies of the submissions.
- Receive rebate checks. Wattsmart typically processes in 6–8 weeks. ThermWise is typically 4–6 weeks. Both come directly to you from the respective utilities.
- Claim the federal tax credit. When you file your 2026 federal return, complete IRS Form 5695. Enter the gross installation cost (before rebates). The IRS does not reduce your tax credit based on utility rebates received — you use the full gross cost to calculate the 30%.
Frequently Asked Questions
Do utility rebates reduce my federal tax credit?
No. The IRS calculates your 25C tax credit on the gross installation cost — you do not subtract utility rebates first. This is confirmed in IRS Publication 946 and has not changed under current law. Stack all programs freely.
What if I already replaced my system last year?
The federal 25C credit applies to the tax year the installation was placed in service. If your installation happened in 2025 and you have not yet filed your 2025 return, you can still claim it on Form 5695 for that year. Utility rebates have strict post-installation submission windows — if you missed the Wattsmart window (typically 90 days from installation), contact RMP directly; they sometimes allow exceptions.
Can I get these rebates on a mini-split?
Yes. Ductless mini-split heat pumps qualify for the same Wattsmart, ThermWise, and IRA credits as ducted split-system heat pumps, provided the equipment meets the same efficiency thresholds. The ThermWise dual-fuel rebate would not apply since mini-splits do not pair with gas furnaces.
What if I rent out part of my home?
The 25C credit applies only to your primary residence, but if you own a single-family home and rent a portion of it, you may still qualify for the credit on the portion of costs attributable to your personal use. Consult a tax professional for your specific situation.
