Which utility serves you
Rebate eligibility tracks which utility services your address — not which city you live in.
- MidAmerican Energy serves Iowa City, Coralville, the bulk of North Liberty, and Tiffin. Provides both electric and natural gas for most addresses. EnergyAdvantage rebate program covers both.
- Eastern Iowa Light & Power Cooperative (EILP) serves rural Johnson County and parts of Linn County outside MidAmerican territory. EILP runs their own rebate program with similar categories.
- Alliant Energy serves Cedar Rapids and parts of Linn County. Their PowerHouse program covers similar categories.
- Iowa City Municipal: Iowa City does not operate its own electric utility; service is MidAmerican.

How to apply
Equipment rebates (HVAC, water heater, etc.)
- Confirm the equipment you're considering qualifies — check the model number against the MidAmerican qualifying products list (your contractor can confirm).
- Complete the install. Get a detailed invoice showing model number, AHRI certification number, install date, and total cost.
- Submit rebate application — either you or your contractor can file. Most corridor HVAC firms file as a courtesy and may pre-discount the rebate from your invoice.
- Application reviewed in 4–8 weeks. Rebate check mailed to homeowner.
Insulation and air sealing
- Schedule a MidAmerican-recognized home energy assessment (or use a participating insulation contractor).
- Have the assessment identify qualifying improvements.
- Complete the work with a participating contractor.
- Submit pre/post measurements with the rebate application.
Smart thermostat
Simplest rebate. Buy a qualifying smart thermostat ($150–$300 retail), install it, log into your MidAmerican online account, submit a photo of the receipt and the installed unit. Often delivered as a bill credit within 30 days.
Stacking with federal IRA tax credits
This is the biggest financial lever in the program — utility rebates and federal credits stack.
Federal Section 25C (Energy Efficient Home Improvement Credit)
30% of qualifying improvements, with category caps:
- Up to $2,000/year for qualifying heat pumps or heat pump water heaters
- Up to $1,200/year for envelope improvements (insulation, doors, windows), with sub-caps
- Up to $600/year for high-efficiency gas furnaces or AC
- Up to $150/year for a home energy audit
The IRA credit is calculated on the gross install cost before utility rebates. A $10,000 heat pump install with a $2,000 MidAmerican rebate still earns a federal credit on the full $10,000 (30% = $3,000, capped at $2,000). Net cost: $10,000 - $2,000 (rebate) - $2,000 (credit) = $6,000.
Federal Section 25D (Residential Clean Energy Credit)
30% of qualifying clean energy installs with no annual cap — primarily solar PV, solar water heating, and geothermal heat pumps. Battery storage paired with solar also qualifies. Carries forward to future tax years if you can't use it all in one year.
HEEHRA (state-administered IRA program)
The federal IRA also funded a High-Efficiency Electric Home Rebate Act (HEEHRA) program administered by state energy offices. For income-qualified households (under 150% of area median income), this can cover up to $8,000 for heat pumps, $1,750 for heat pump water heaters, plus electrical panel upgrades and wiring. Iowa's program status varies; check the Iowa Economic Development Authority for current launch status.
Install cost: $10,000
MidAmerican rebate: −$2,000
Federal 25C credit (30% of $10K, capped at $2K): −$2,000
Net cost: $6,000 (40% saved)
EILP and Alliant programs
If your service is Eastern Iowa Light & Power or Alliant Energy instead of MidAmerican, the categories are similar but specific amounts and qualifying equipment lists differ. EILP runs a member rebate program with heat pump, HVAC, and smart thermostat rebates. Alliant's PowerHouse covers a similar slate. Check directly with your utility for current offerings.
Common mistakes to avoid
- Buying before verifying eligibility. Equipment must be on the qualifying list at the time of purchase. The list updates as federal efficiency standards change.
- Losing the AHRI certificate. AC and heat pump rebates require an AHRI matched-system certificate showing the outdoor unit and indoor coil. Your installer should provide it; save it with the invoice.
- Missing the deadline. Rebate applications typically must be submitted within 90 days of install. Don't sit on the paperwork.
- Assuming the contractor filed. Some contractors say they'll file and don't. Confirm and follow up. The check goes to the homeowner, so MidAmerican needs your account info.
- Forgetting the federal credit. The tax credit is filed with your annual return on IRS Form 5695. You need the receipt and the equipment manufacturer's qualification statement.
Worth the bother?
For HVAC replacements you were going to do anyway, the answer is unambiguously yes — the rebate is free money for paperwork you'd already be filling out. For envelope upgrades (insulation, air sealing) the rebate often funds 30–50% of the project cost and pays for itself in 1–3 years of reduced utility bills.
The smart thermostat rebate is the easiest: $50–$100 back on a $150–$300 device that pays for itself in heating/cooling savings within 1–2 years anyway. If you don't have one yet, it's the lowest-effort efficiency upgrade in your house.

Frequently asked questions
Which utility serves my address?
MidAmerican Energy serves most of Iowa City, Coralville, and North Liberty. Eastern Iowa Light & Power serves rural Johnson and Linn County. Check your bill or use the utility's service-territory lookup.
How do I apply?
Most rebates are post-install: complete the work, submit application with invoice and AHRI certificate, receive check in 4–8 weeks. HVAC contractors typically file on your behalf as a courtesy.
Can I stack with federal credits?
Yes. Utility rebates do not reduce federal IRA tax credits. A heat pump install can earn the MidAmerican rebate, the 30% federal credit (up to $2,000), and qualify for state programs simultaneously. The federal credit is calculated on gross install cost.
What are the biggest rebate categories?
Cold-climate heat pumps ($1,500–$3,000+) and geothermal ($2,000–$5,000+) are the largest. High-efficiency furnaces $300–$800. Heat pump water heaters $300–$700. Insulation by area or set amount. Smart thermostats $50–$100.
Are these amounts current?
Approximate for 2026. MidAmerican adjusts amounts annually. Verify current values at midamericanenergy.com before counting on specific figures.
