Vermont: HVAC Replacement Cost Calculator

Replacing an HVAC system in Vermont typically runs $3,500 to $13,000 installed, depending on the equipment you choose. A gas furnace replacement lands between $3,500 and $7,000, while a heat pump generally costs $6,000 to $12,000 and a matched AC-plus-furnace system runs $7,500 to $13,000. Vermont sits in climate zone 6, so heating capacity drives most equipment decisions here, and local labor rates run about 4% above the national average.

Worked example

Take a 1,900 sq ft two-story home in central Vermont with existing ductwork and an aging gas furnace. The homeowner replaces the furnace and adds central air in the same visit, a job that falls in the $7,500 to $13,000 AC-plus-furnace range. Because the ducts are already in place and only minor sheet metal transitions are needed, this project would land near the middle of that range, roughly $9,500 to $10,500 - moving toward the $13,000 end if the home needs duct sealing, a new line set run, or higher-efficiency equipment sized for zone 6 winters.

Frequently asked questions

How much does a heat pump cost to install in Vermont?

Heat pump installations in Vermont generally run $6,000 to $12,000 installed. Ducted whole-home systems sit toward the top of that range, while smaller or simpler installations land closer to $6,000. Ductless mini splits are a separate category and start around $3,500.

Is a ductless mini split cheaper than central air in Vermont?

A single-zone ductless mini split can start around $3,500, which is below the $4,000 low end for central AC. But multi-zone mini split systems reach up to $10,000 in Vermont, so once you are conditioning several rooms the price gap narrows or disappears entirely.

Should I replace my furnace or switch to a heat pump?

A gas furnace replacement is the lower-cost path at $3,500 to $7,000 installed, versus $6,000 to $12,000 for a heat pump. In Vermont's climate zone 6, heat pumps need to be sized and selected for sustained cold-weather heating, which pushes many installs toward the upper half of the range. Some homeowners keep the furnace as backup heat rather than removing it.

Why does HVAC installation cost more in Vermont?

Vermont's labor index sits at 1.04, meaning installation labor runs about 4% above the national average, with HVAC technicians earning around $32.24 per hour. Zone 6 heating loads also mean larger or cold-climate-rated equipment, which adds to the equipment side of the bill.
