How do I know if I should repair or replace my furnace?
A common rule is the 5,000 rule — multiply the furnace age by the repair cost. If the number exceeds $5,000, replacement is usually the better investment. A furnace older than 15 years with a repair quote over $500 is often a replacement candidate.
What's the difference between a gas and electric furnace?
Gas furnaces burn natural gas to generate heat and are the most common in King and Snohomish County. Electric furnaces use heating elements and are cheaper to install but more expensive to operate in most of Washington. Heat pumps are increasingly replacing both.
What is a heat pump and how is it different from a furnace?
A heat pump moves heat rather than generating it — pulling warmth from outside air even in cold weather. Modern cold-climate heat pumps work well in the Pacific Northwest and qualify for significant rebates from PSE, Snohomish PUD, and the federal 25C tax credit.
Are there rebates for furnace replacement in Washington?
Yes — particularly for heat pump conversions. Puget Sound Energy and Snohomish PUD offer rebates on qualifying heat pump systems. The federal Inflation Reduction Act provides up to $2,000 in tax credits for heat pump installations. Ask your installer about current offers before signing.
Is this an exact quote?
No. This gives you a realistic local range based on homes and installs similar to yours. A specialist can confirm the exact number for your situation.
