Fort Collins, Colorado: HVAC Replacement Cost Calculator

Replacing an HVAC system in Fort Collins typically runs $3,500 to $7,000 for a gas furnace alone, $4,000 to $7,500 for central air conditioning, and $7,500 to $13,000 for a matched furnace-and-AC pair. Local labor runs about 10% above the national baseline, with HVAC technicians in the area earning around $34.29 an hour, so installation time is a meaningful share of your quote. Fort Collins sits in climate zone 5, where cold winters push most homeowners toward heating capacity first and cooling second.

Worked example

Take a 1,900-square-foot two-story home in southeast Fort Collins with a 20-year-old gas furnace and an outdoor AC unit that both need to go. Because the ductwork is intact and the equipment sits in an accessible basement mechanical room, a mid-efficiency matched system would land near the middle of the $7,500 to $13,000 range for an AC-plus-furnace replacement, roughly $10,000. Adding a higher-efficiency variable-speed furnace, a new line set, or electrical upgrades would push the same job toward the $13,000 end.

Frequently asked questions

Is a heat pump worth it in Fort Collins winters?

Heat pumps in Fort Collins run $6,000 to $12,000 installed, which is more than a standalone gas furnace at $3,500 to $7,000. In climate zone 5, most homeowners who go this route pair the heat pump with backup heat for the coldest stretches, so ask contractors to quote the full system rather than the outdoor unit alone.

Why are Fort Collins HVAC quotes higher than national averages?

Labor in the Fort Collins market runs about 10% above the national baseline, and local HVAC technicians earn roughly $34.29 per hour. Since a full changeout is typically a one- to two-day job for a crew, that wage difference shows up directly in your installed price.

How much does it cost to just replace my furnace in Fort Collins?

A gas furnace replacement alone runs $3,500 to $7,000 installed in Fort Collins. Simple swaps of a similar-capacity unit in an accessible basement fall toward the low end, while high-efficiency condensing models that need new venting and a condensate drain push toward $7,000.

What about a home addition or a room without ductwork?

Ductless mini splits run $3,500 to $10,000 in Fort Collins, with single-zone systems for one bonus room or finished basement at the low end and multi-zone setups covering several rooms at the top. They are usually cheaper than extending ductwork, and they provide both heating and cooling from the same unit.
