Spokane, Washington: HVAC Replacement Cost Calculator

Most Spokane homeowners spend between $3,500 and $13,000 to replace an HVAC system, depending on what they're putting in. A gas furnace alone typically runs $3,500 to $7,000 installed, while a matched AC-and-furnace replacement lands between $7,500 and $13,000. Heat pumps, which handle both heating and cooling, fall in the $6,000 to $12,000 range in the Spokane market.

Worked example

Take a 1,900-square-foot two-story home on Spokane's South Hill with a 20-year-old gas furnace and an outdoor AC unit of about the same age. Because both pieces are at end of life and share the same ductwork and electrical, replacing them together as a matched system is the practical call, putting the job in the $7,500 to $13,000 range. With a straightforward basement furnace swap, existing ducts in usable shape, and no major venting changes, this home would likely land near the middle of that range — but Spokane's labor costs run about 22% above the national baseline, so quotes here tend to sit higher than what national averages suggest for the same equipment.

Frequently asked questions

Why do Spokane HVAC quotes come in higher than national averages?

Installation labor in Spokane carries a local index of 1.22, meaning labor runs roughly 22% above the national baseline, and the average HVAC technician wage here is about $37.91 an hour. Equipment prices are fairly consistent nationwide, so most of the gap between a national average and your Spokane quote comes from the labor line.

Does a heat pump make sense in Spokane's winters?

Spokane sits in climate zone 4, which means real winter heating load but not the extreme cold of the northern plains. Heat pumps run $6,000 to $12,000 installed here and cover both heating and cooling in one system, though many Spokane homeowners pair one with gas backup heat for the coldest stretches, which adds to the total.

How much does it cost to replace just the air conditioner in Spokane?

A standalone central AC replacement in Spokane runs $4,000 to $7,500 installed. If your furnace is also 15 years or older, it's usually worth pricing the pair together — the combined job is $7,500 to $13,000, and doing both at once avoids paying twice for the same labor and refrigerant work.

Are ductless mini splits cheaper than a full system in Spokane?

Ductless mini splits run $3,500 to $10,000 in Spokane, with the low end covering a single zone and the high end covering multi-head setups. They're most cost-effective for older Spokane homes without existing ductwork, additions, or finished basements and attics where extending ducts would be expensive.
