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.

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)
- 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
- Insist on a Manual J load calculation, not a square-footage guess.
- Get at least three written bids before you sign.
- Ask every bidder for the same SEER2/AFUE rating so you compare like for like.
- Confirm old-unit removal, the permit and startup testing are all included.
Questions to ask Lakewood HVAC pros
The only honest way to compare is to hold every quote to one checklist. Start with these.
- 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?
Replacing the complete HVAC system — furnace plus central AC or heat pump — together. Where two homes diverge is in the details below. Grade of equipment and materials tops the list, followed by home size and complexity, local labor, and the mixed climate zone.
How much should you really budget for HVAC in 2026?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
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
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.
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.
