Oregon: HVAC Replacement Cost Calculator

Replacing an HVAC system in Oregon typically runs $3,500 to $13,000 installed, depending on what you put in. A heat pump — the most common full-system swap in Oregon's mild climate zone 4 — lands between $6,000 and $12,000, while a straight gas furnace replacement is closer to $3,500 to $7,000. Labor in Oregon runs about 6% above the national average, with HVAC technicians earning around $32.90 an hour.

Worked example

Take a 1,900 sq ft single-story home in the Willamette Valley with an aging gas furnace and no air conditioning. The homeowner replaces the furnace with a ducted electric heat pump, reusing most of the existing ductwork but adding a new electrical circuit and pad. With one to two days of crew time and a mid-efficiency variable-speed unit, this job would land near the middle of Oregon's $6,000-$12,000 heat pump range — roughly $8,500 to $9,500. Choosing a high-efficiency variable-capacity model or needing significant duct repair would push it toward the $12,000 end.

Frequently asked questions

Is a heat pump worth it in Oregon instead of a gas furnace?

Oregon sits in climate zone 4, where winters are mild enough that a heat pump can handle most heating hours without heavy backup heat. A heat pump costs more up front — $6,000 to $12,000 versus $3,500 to $7,000 for a gas furnace — but it also provides cooling, which a furnace alone does not.

How much does it cost to add air conditioning to an Oregon home that already has a furnace?

Adding central AC to an existing forced-air system runs $4,000 to $7,500 installed in Oregon. If your furnace is also near the end of its life, replacing both at once costs $7,500 to $13,000 and avoids paying for a second round of labor later.

What does a ductless mini split cost in Oregon?

Ductless mini splits run $3,500 to $10,000 in Oregon. A single-zone unit for one room or an addition sits at the low end, while a multi-zone system covering several rooms in a home without ductwork pushes toward the top of that range.

Why are HVAC installation costs higher in Oregon than the national average?

Labor in Oregon runs about 6% above the national average, with HVAC technicians earning roughly $32.90 per hour. Since labor is a large share of any installation, that difference shows up in the final installed price — especially on multi-day jobs like a full furnace-and-AC replacement.
