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 Spokane
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
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)
- 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.
- Sizing was guessed from square footage instead of a Manual J load calculation, so the equipment is wrong.
Get an apples-to-apples bid
- Get at least three written bids before you sign.
- 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.
- Insist on a Manual J load calculation, not a square-footage guess.
Questions to ask Spokane 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 Spokane?
Expect to pull a HVAC permit in Spokane — about $225 — which is already built into the estimate above, not an extra charge.
What affects full HVAC system replacement cost the most?
Replacing the complete HVAC system — furnace plus central AC or heat pump — together. Four things drive the number more than anything else — equipment/material grade, home size and complexity, local labor, and your mixed climate zone.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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
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.
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.
