Local guide
How heat pumps work in Seattle
An air source heat pump in Seattle typically starts around $9,800 installed, including the unit, cylinder, controls and commissioning. A full conversion can cost more where radiators or pipework need upgrading.
Because a heat pump runs at lower flow temperatures than a boiler, the survey is the most important part of the job. Installers measure room-by-room heat loss, check radiator sizes and look at where a hot water cylinder can go — in Seattle that usually decides whether the quote is realistic.
Ask every installer for the modelled running cost at your actual tariff, not just the efficiency figure, and confirm what happens to your existing boiler or heating system once the pump is in.

Local incentives for Seattle homeowners
30% federal tax credit
The Residential Clean Energy Credit covers 30% of solar, battery and heat pump costs through 2032, with no cap.

Many states add cash rebates, property-tax exemptions and low-interest financing on top of the federal credit.
Net metering
Most states credit you for surplus solar you export to the grid, offsetting evening and winter usage.
Heat Pumps in Seattle: common questions
Do I need to replace my radiators?
Not always. Many homes only need two or three oversized radiators swapped, and the heat loss survey shows exactly which ones.
Is a heat pump noisy?
Modern units run at a similar level to a fridge from a few metres away. Siting matters, so installers position the unit away from bedrooms and boundaries.
Can I keep my boiler as backup?
Some systems are designed as hybrids, but most grant schemes require the boiler to be removed or decommissioned, so confirm this before signing.
How much does a solar system cost in the US?
Most residential systems land between $12,000 and $22,000 before the 30% federal credit, depending on system size and state. A typical 7kW system in a sunny state pays back in 7–9 years.
What does accredited mean on this directory?
Every installer marked as verified has supplied a NABCEP certification number that our team checks against the public register before the badge is granted.
How long does installation take?
Most residential installs are completed in one to two days on site, with permitting and utility interconnection adding two to eight weeks depending on your city.
Do I need a new roof before installing?
If your roof has less than 10 years of life left, installers will usually recommend replacing it first so the array does not need to be removed later.
