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 Westland

Why full HVAC system replacement quotes vary — and how to compare them fairly
A wide spread between bids rarely means someone is overcharging; it usually means they priced different work. Below is what moves the number and how to line the quotes up.
Why a quote looks high (or low)
- One quote bundles ductwork, electrical, permit and old-unit removal; another quietly leaves them out.
- 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.
Get an apples-to-apples bid
- Require an itemized quote splitting equipment, labor, permit and add-ons.
- Confirm old-unit removal, the permit and startup testing are all included.
- Ask every bidder for the same SEER2/AFUE rating so you compare like for like.
- Get at least three written bids before you sign.
Questions to ask Westland HVAC pros
You can't judge bids side by side unless they cover the same ground; run through these with every pro on your list.
- 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?

What affects full HVAC system replacement cost the most?
Replacing the complete HVAC system — furnace plus central AC or heat pump — together. From there, a handful of specifics push the final number up or down. The biggest drivers are equipment/material grade, the size and complexity of your home, local labor rates, and your climate zone (cold).
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 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 budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
The longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
Skip the brand debate. A correctly sized system, an efficiency tier that fits your climate, and a properly commissioned install will save you more than any label ever could.
