Roughly $1,000–$5,000+ per heat pump depending on size and type; more for income-qualifying homes.
Status: NYS Clean Heat is delivered through your utility; income-qualified households can stack the state's HEAR rebate.
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.

Why full HVAC system replacement quotes vary — and how to compare them fairly
Two bids for the “same” job can differ by thousands. Usually it's scope, not greed — here's what moves the number and how to get an apples-to-apples comparison.
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
- Insist on a Manual J load calculation, not a square-footage guess.
- Ask every bidder for the same SEER2/AFUE rating so you compare like for like.
- Require an itemized quote splitting equipment, labor, permit and add-ons.
- Get at least three written bids before you sign.
Questions to ask Brentwood HVAC pros
Comparing quotes is only fair when they cover the same scope. Ask every bidder these before you sign.
- 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?
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?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
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 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.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
