The short answer
$4,500–$8,500
Installed price for a typical Seattle-area home. Simple swap-in-place sits low; high-efficiency condensing units with new venting sit high. Electric furnaces run $2,000–$6,500.

What moves the price
Efficiency tier
An 80% furnace burns a dollar of gas for 80¢ of heat; a 96% condensing unit wastes almost nothing — but needs PVC venting and a drain, which is real install work.
Staging and blower
Single-stage is on/off. Two-stage and modulating furnaces with ECM blowers cost more and feel better — steadier heat, quieter, cheaper to run.
Venting and code
Replacing like-for-like is simple. Changing efficiency class means new venting, condensate, sometimes gas-line tweaks — all visible in the quote, never after.
Size
Bigger is not better — an oversized furnace short cycles its way to an early grave. We size to the house, not the brochure.

Quick answers
Is 95% efficiency worth the premium?
On a Western Washington heating season, usually yes over the furnace’s life — roughly 15% less gas than an 80% unit, and utility rebates often apply to high-efficiency equipment. We run your actual numbers at the quote.
Furnace or heat pump?
Our mild lowland winters are ideal heat pump territory — and a heat pump adds cooling. If your AC is also aging, one heat pump can replace both. We price whichever paths make sense for your house.
How long does replacement take?
A straightforward swap is one day. Venting changes or duct modifications can add a second. You’ll know the timeline with the quote.
