Rebates & incentives in Washington
HEAR liveThe largest 2026 HVAC incentives target heat pumps; other equipment mainly qualifies for utility efficiency rebates.
- Washington Home Energy Rebates (HEAR) ↗WA Dept. of Commerce
$8,000+ toward a heat pump for eligible households; more when stacked with utility rebates.
Status: Washington's HEAR launched for income-qualifying households; stacking with utility programs can exceed $10,000.
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 Kirkland
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
Big gaps between bids come down to scope far more often than greed. This breaks down the levers and how to force a like-for-like comparison.
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.
- Brand, warranty length and whether startup/commissioning is included all move the number.
Get an apples-to-apples bid
- Get at least three written bids before you sign.
- Insist on a Manual J load calculation, not a square-footage guess.
- 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.
Questions to ask Kirkland 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?

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 mixed climate zone.
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
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.
The efficiency-first case
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
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.
