What changes the price
- Furnace size (BTUs) from a Manual J load calculation
- Efficiency: 80% vents through the existing flue; 96%+ condensing needs PVC venting and a drain
- Ductwork, return air, and gas line condition
- Attic, crawlspace, or tight-closet installs
- PPRBD permit and required code updates
Altitude & Front Range context
Gas furnaces lose roughly 4% of output per 1,000 feet of elevation, so a furnace at 6,035 ft must be derated and sized for real output — not the sticker BTU. That's why we never size by square footage alone.
When to call a pro
- Your furnace is 15+ years old or needed repairs the last two winters.
- Rooms heat unevenly or bills keep climbing.
- You want an exact, upfront quote — estimates are free.

What size furnace do I need at 6,000+ feet?
It depends on your home's square footage, insulation, windows, and layout — not a rule of thumb. Gas furnaces lose output at Colorado Springs' altitude, so Strong Heating And Cooling runs a Manual J load calculation and sizes for derated output. See our high-altitude furnace sizing guide for the details.
How long does a furnace or AC install take?
Most straightforward like-for-like furnace or AC replacements in Colorado Springs are completed in a single day. Jobs that need new venting, ductwork changes, or a full system swap can take longer; we give you the timeline with your upfront quote.
What's the best furnace or AC brand for Colorado?
Installation quality and correct sizing matter more than the logo. Strong Heating And Cooling services all major brands — including Carrier, Trane, Lennox, Daikin, Goodman, Rheem, and Mitsubishi Electric — and recommends equipment that is properly rated and calibrated for high altitude.

Furnace Replacement Cost in Colorado Springs
Local Furnace Replacement Cost Done Right
Furnace replacement cost in Colorado Springs depends on three things: the efficiency of the furnace you choose, the venting and gas work your home needs, and whether the ductwork can move the air the new equipment is rated for. Our installed prices start at $4,500 and include equipment, labor, permit, and haul-away.
Old furnace replacement in older neighborhoods often adds flue or combustion-air work, while newer Powers and Northgate homes are usually a straight swap. Either way you get one number before we start — not an hourly surprise afterward.
Repair Or Replace?
When To Replace A Furnace
15+ Years Old
Most gas furnaces last 15–20 years. Past that, efficiency drops and parts get harder to source.
Rising Gas Bills
Burning more fuel for the same comfort means the heat exchanger and burners are past their prime.
Repeat Repairs
Two or more repairs in a couple of seasons usually costs more than putting that money toward a new furnace.
Cold Or Uneven Rooms
Rooms that never warm up often point to a failing or badly sized furnace, not just a closed vent.
Cracked Heat Exchanger
A cracked exchanger is a carbon monoxide risk. We red-tag it and replace it — never patch it.
Short-Cycling Or Loud Operation
Banging, rumbling, or constant stopping and starting is a furnace near the end of its life.

What Drives Your Furnace Replacement Price
