Is a heat pump worth it in Snohomish?

This one's marginal in Snohomish: it only clears if you stay long enough. $3,500 is what Snohomish would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $318 saved annually, for a payback of roughly 11 years. It's a genuine toss-up here — Snohomish's numbers don't point clearly either way.

How cold Snohomish actually gets

Snohomish has a real but manageable winter — 4489 heating degree days a year against a 65°F base — and summers rarely ask much of an air conditioner, at 200 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 18°F, against a record low of 12.9°F. That puts the seasonal coefficient of performance at 3.13 for the recommended cold-climate unit. Snohomish needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. Climate figures trace to the nearest NOAA station, SNOHOMISH CO (PAINE FD) AP, 8.8 miles from Snohomish.

Snohomish's running-cost comparison, in dollars

Electricity use for heating alone comes out to about 3,632 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $543 a year. The gas furnace it replaces burns roughly 47 Mcf a year at 17.62 per Mcf here, for a running cost near $861 a year (electricity here runs 14.27¢/kWh). Buy it outright, not incrementally, and payback stretches to 42.4 years; over 15 years the net position sits $1,273 ahead.

Electric resistance heat in Snohomish, compared

Plenty of homes in Snohomish heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Snohomish's answer improves. About $1,116 a year comes back this way, enough that the 7.2-year payback clears the $8,000 premium comfortably within the equipment's life.

Where Snohomish ranks in this dataset

Snohomish lands at position 1213 out of 3206 cities on heating severity (coldest is 1), and 3083 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Deciding what's next in Snohomish, WA

Snohomish, Washington is home to about 10,534 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Snohomish, nothing is lost by holding off until the current equipment genuinely fails.

Ask a local HVAC contractor for a quote before committing either way.

More on how this number was built

The methodology guide walks through exactly how Snohomish's 3.13 seasonal COP and the rest of this page's numbers get built. Snohomish's 18°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
