What affects your Washington HVAC rebate amount?

Your electric utility
Pacific Power (WA), Puget Sound Energy (PSE), Seattle City Light and other participating utilities each run their own rebate tiers. The same equipment may qualify for different amounts depending on your utility.
Current heating fuel
Homes heating with oil or propane typically qualify for the highest heat pump rebate tiers. Your current fuel type is one of the most important eligibility factors.
Whole-home vs. partial-home scope
The whole-home rebate path — where the heat pump replaces all or most of the home's heating — typically carries the highest rebate. Partial or supplemental installations qualify for lower amounts.
System size and equipment certification
Larger systems earn larger rebates in most programs. Equipment must meet efficiency thresholds verified by an AHRI or similar certification.
Income qualification
Income-qualified households may access enhanced rebate tiers or additional assistance. Contact your utility to confirm documentation requirements.

What to check before signing an HVAC quote in Washington

Does the quote include the equipment certification number (AHRI or program-specific)?
Does it list your specific utility and your current heating fuel?
Does it state whether the rebate is for a whole-home or partial-home installation?
Does the quote confirm the rebate is from Pacific Power Wattsmart and not a made-up figure?
Are savings assumptions documented (fuel price, electricity rate, system efficiency)?
Is a home energy assessment required first, and if so, has it been scheduled?
Have a quote already?
Check for rebate claim gaps, missing equipment documentation, and red flags before signing.

Frequently Asked Questions

What HVAC rebates are available in Washington?

Washington homeowners can access HVAC rebates through Pacific Power Wattsmart for heat pumps, insulation, air sealing, and heat pump water heaters.

Can I stack Washington rebates with the federal tax credit?
