The chart below shows a comparison of annual home heating fuel costs based on the most recent infor-mation obtained from suppliers in Snohomish County. The chart also shows that electric heat pumps continue to provide a very cost-effective heating source. (Electric costs based on PUD residential billing rate of 10.4 cents per kilowatt-hour.)
The costs are based on the space heating needs for an average single family home. Individual consump-tions can vary significantly, depending on thermostat settings, air leakage, house construction, and other factors.

Stellar service provider. I got multiple in-home quotes. Bill was not the least expensive, but he told it all to me straight. He gave me the pros and cons of all decisions and didn't try to upsell me on anything. Price-wise, he was on the higher side. But his competence and candor gave me all the peace of mind I needed to go with him over the others. Finally, when I wanted something tweaked with how they installed my furnace, he scheduled a crew member to come out and make the change I wanted, free of charge. It was only an additional hour of labor, but it's more than enough to get me on here writing a review. You won't be disappointed with Cascade.
