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.

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)
- Sizing was guessed from square footage instead of a Manual J load calculation, so the equipment is wrong.
- One quote bundles ductwork, electrical, permit and old-unit removal; another quietly leaves them out.
- 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
- Ask every bidder for the same SEER2/AFUE rating so you compare like for like.
- Get at least three written bids before you sign.
- Confirm old-unit removal, the permit and startup testing are all included.
- Require an itemized quote splitting equipment, labor, permit and add-ons.
Questions to ask Dearborn Heights HVAC pros
Before you pick, make each contractor answer the same things — gaps in their replies tell you as much as the price.
- 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?

How much should you really budget for HVAC in 2026?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
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.
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.
