Furnace Installation
New furnace installation built for Colorado winters. High-efficiency systems, expert installation, and warranties you can count on.
About This Service
Colorado winters demand a furnace that runs reliably at -10°F. We install high-efficiency gas, propane, and electric furnaces sized exactly for your home and Denver’s elevation. Our installations include proper venting (especially critical at altitude), gas line work, and combustion air calculations.nnWe partner with Trane, Lennox, Goodman, and Carrier — and we pull permits, run a combustion analysis at startup, and educate you on filter changes and operation. Most furnace replacements take 1 day.

Frequently Asked Questions
Common questions about furnace installation in Colorado.
Can I get a quote for a new furnace in Colorado?
Yes — every quote is free and includes proper sizing for your home and altitude. Pricing varies by efficiency, fuel type (gas, propane, electric), and brand, so we always assess on-site. Schedule a no-obligation estimate today.
What efficiency rating is best for Colorado?
For Colorado homes, 95–96% AFUE high-efficiency furnaces hit the sweet spot. They qualify for Xcel rebates, noticeably reduce gas usage, and pay back the efficiency upgrade through lower monthly bills.
How long does furnace installation take?
Standard furnace replacement (same fuel type, same location) is a 1-day job. Conversions (electric to gas, or relocations) take 1.5-2 days.
Do I need a permit for furnace replacement in Denver?
Yes — Denver, Aurora, Lakewood, and most Colorado cities require a mechanical permit and inspection for furnace replacement. We handle this for you.
Will a new furnace lower my heating bills?
A 96% efficient furnace replacing an older 80% unit typically cuts heating bills by 15-20%. Combined with smart thermostat installation, savings can reach 25-30% in Colorado's long winters.
