Common Questions About Furnace Installation
How much does a new furnace cost in Fort Collins?
A gas furnace that meets Colorado’s 2026 NOx standard costs about $7,000 to $10,000 installed in Northern Colorado. Your price depends on the furnace size and efficiency, plus any ductwork your house needs. Lion Care Club members take 15% off equipment replacements. Our 2026 furnace cost guide breaks the numbers down further.
What does Colorado’s 2026 ultra-low NOx furnace standard mean for Northern Colorado homeowners?
Beginning January 1, 2026, new covered gas furnaces sold or installed in Colorado must meet the state’s ultra-low nitrogen oxide (NOx) emissions standard. In Northern Colorado, a compliant gas furnace typically costs about $7,000 to $10,000 installed, depending on equipment, installation requirements, and the home.
How long does a furnace installation take?
Most furnace swaps finish in one day. Switching to a heat pump or adding new ductwork can add a second day, and our technician will tell you the timeline before you sign.
Do I need a permit to replace my furnace?
Yes. The City of Fort Collins requires a mechanical permit for every furnace install, at $65 per heating appliance plus tax. Our office pulls the permit and schedules the inspection, so you never have to visit the building department.
Should I get a heat pump or a gas furnace?
A heat pump heats your home in winter and cools it in summer, which makes it a strong fit when your air conditioner is also aging. Some Fort Collins homeowners pair a heat pump with a gas furnace for the coldest nights, a setup called dual fuel. Our technician prices each option so you can compare them side by side.
What warranty comes with a new furnace?
Most furnace makers cover parts for 10 years once you register the unit. Register it before the manufacturer’s deadline to keep that coverage. Lion adds the Happy Neighbor Guarantee on top of the manufacturer’s coverage.
