Rebates & incentives in Oregon
The largest 2026 HVAC incentives target heat pumps; other equipment mainly qualifies for utility efficiency rebates.
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.

Cheapest time for full HVAC system replacement in Eugene
Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
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)
- Equipment tier isn't matched — a 14.3 SEER2 bid will always undercut an 18 SEER2 one for the "same" job.
- Brand, warranty length and whether startup/commissioning is included all move the number.
- One quote bundles ductwork, electrical, permit and old-unit removal; another quietly leaves them out.
Get an apples-to-apples bid
- Get at least three written bids before you sign.
- 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.
- Require an itemized quote splitting equipment, labor, permit and add-ons.
Questions to ask Eugene HVAC pros
Level the field before you choose — ask each bidder the same questions and watch how the answers differ.
- 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?

Do I need a permit for full HVAC system replacement in Eugene?
Most Eugene jurisdictions require a HVAC permit for this work. Budget roughly $225 for the permit; it is already included in the estimate above.
What affects full HVAC system replacement cost the most?
Replacing the complete HVAC system — furnace plus central AC or heat pump — together. Where two homes diverge is in the details below. What should you watch? Equipment or material grade, the home's size and complexity, local labor rates, and your mixed climate zone — in roughly that order.
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 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 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
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.
If there's one takeaway, it's this: sizing and install quality decide whether an HVAC system performs, not the badge on the box. Get the load calculation right, match efficiency to climate, and take the rebates on offer.
