Most Seattle homes still heat with a gas furnace. Most of those homes would be more comfortable, pay less per month, and qualify for thousands of dollars in rebates if they switched to a cold-climate heat pump. Here's the case.
Seattle's climate is almost ideal for heat pumps
The single biggest drag on heat-pump efficiency is extreme cold — below about 5°F, even the newest cold-climate units start losing capacity. Seattle's winter low averages 28°F. We rarely see sustained cold below 20°F. That puts us right in the sweet spot where a modern variable-speed heat pump operates at peak efficiency essentially all year. The same unit cools your house in August. One system, both jobs.
The IRA tax credit is real money
The Inflation Reduction Act's 25C tax credit covers 30% of the install cost of a qualifying heat pump, up to $2,000. Stack that with PSE's heat-pump rebate (currently $1,200) and Washington State's HEEHRA program for income-qualifying households (up to $8,000), and a $14,000 install can land under $7,000 out-of-pocket.
We submit every rebate on your behalf. The federal credit you claim on your taxes the year after install; the PSE and state rebates we file directly.
Power bills go down, not up
Modern variable-speed heat pumps run at 200-300% efficiency on most days — meaning they deliver 2-3 watts of heat for every 1 watt of electricity. A gas furnace tops out at 98% efficiency, and that's the high-end models.
For an average Seattle home, switching from a gas furnace + window AC to a single variable-speed heat pump cuts monthly bills by $40-80 in summer and roughly breaks even in winter. Over a 15-year system lifespan, that's $7,000-$15,000 saved.
The catch
If your home has poor insulation, leaky ducts, or single-pane windows, a heat pump will struggle to keep up on the coldest mornings. Before quoting an install, we do a Manual J load calculation, a duct review, and a quick infrared scan of the building envelope. If we find a problem that'll hurt heat-pump performance, we tell you up front — either let's fix it first, or stick with the gas furnace.
Who should not switch yet
If your gas furnace is less than 10 years old and running well, the math on replacing it now is hard to justify. We'll tell you that honestly. Sometimes the right answer is "wait five years."
