Rebates & incentives in Michigan
HEAR liveThe largest 2026 HVAC incentives target heat pumps; other equipment mainly qualifies for utility efficiency rebates.
- Michigan Home Energy Rebates (HEAR) ↗Michigan EGLE
Roughly $7,000–$8,500 toward a heat pump for eligible households.
Status: Michigan's HEAR program launched in 2025–2026 for income-qualifying households.
The federal 25C tax credit (up to $2,000 for heat pumps; $600 for high-efficiency AC or furnaces) and the 25D credit ended December 31, 2025 under the One Big Beautiful Bill Act — neither is available for 2026 installs. The remaining federal help is the IRA Home Electrification & Appliance Rebates (HEAR): up to $8,000 toward a heat pump for households under 150% of area median income, paid at point of sale where a state has launched its program.
Verified July 2026. Rebate budgets deplete and program windows change fast — confirm current amounts and eligibility with your utility and the DSIRE database before you budget. Costadia does not administer these programs.
Cheapest time for full HVAC system replacement in Novi
Demand for HVAC work falls off a cliff in the shoulder months, and contractors discount to keep their crews booked. Wait for a 100-degree day or a hard freeze, though, and you're paying emergency rates for a system that just quit.
Why full HVAC system replacement quotes vary — and how to compare them fairly
Two contractors can price the same job thousands apart. Almost always it's the scope each assumed — here's what drives the gap and how to close it.
Why a quote looks high (or low)
- Sizing was guessed from square footage instead of a Manual J load calculation, so the equipment is wrong.
- Equipment tier isn't matched — a 14.3 SEER2 bid will always undercut an 18 SEER2 one for the "same" job.
- One quote bundles ductwork, electrical, permit and old-unit removal; another quietly leaves them out.
Get an apples-to-apples bid
- Require an itemized quote splitting equipment, labor, permit and add-ons.
- Ask every bidder for the same SEER2/AFUE rating so you compare like for like.
- Insist on a Manual J load calculation, not a square-footage guess.
- Get at least three written bids before you sign.
Questions to ask Novi HVAC pros
A fair comparison starts with identical questions. Ask each contractor the following before anything gets signed.
- 1Did you run a Manual J load calculation to size the system, or estimate from square footage?
- 2What AFUE/SEER2 rating is this unit, and what's the payback vs. the next tier up?
- 3Is removal of the old equipment, the permit, and startup testing included in the quote?
- 4Will my existing ductwork and venting work as-is, or is repair/resizing needed?
- 5What's covered under the labor warranty vs. the manufacturer's parts warranty?

Worth knowing first: replacing the complete HVAC system — furnace plus central AC or heat pump — together. Price swings mostly come down to equipment or material grade, the size and complexity of the home, local labor, and the cold climate zone.
How much should you really budget for HVAC in 2026?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
The budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
The efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
The longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
The brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
