Rebates & incentives in Washington
HEAR liveHeat pumps qualify for the largest 2026 incentives — this is the equipment state and utility rebate programs are built around.
- 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.

Cheapest time for heat pump installation in Sammamish
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 heat pump installation 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.
- 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.
Get an apples-to-apples bid
- Confirm old-unit removal, the permit and startup testing are all included.
- Require an itemized quote splitting equipment, labor, permit and add-ons.
- Get at least three written bids before you sign.
- Insist on a Manual J load calculation, not a square-footage guess.
Questions to ask Sammamish 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?

Do I need a permit for heat pump installation in Sammamish?
Expect to pull a HVAC permit in Sammamish — about $250 — which is already built into the estimate above, not an extra charge.
What affects heat pump installation cost the most?
Installing an air-source heat pump that provides both heating and cooling. From there, a handful of specifics push the final number up or down. 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?
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 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 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 most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
