Local Furnace Expertise

A Furnace Sized for Your Home and Altitude

A new furnace performs best when the equipment, airflow, venting, gas pressure, and controls are designed as one system. We evaluate your home and existing installation instead of simply matching the old model number.

Options include an 80% AFUE two-stage variable-speed furnace, a 96% AFUE variable-speed condensing furnace, and a 98% AFUE modulating furnace. We explain comfort, efficiency, venting, and budget tradeoffs clearly.

When to Consider Furnace Replacement

  • The furnace is 15 years old or older
  • Repairs are becoming frequent or expensive
  • Heating bills rise without a clear reason
  • Rooms heat unevenly
  • The heat exchanger or major component has failed
  • You want quieter, steadier, more efficient comfort

Colorado Springs High-Altitude Guide

What Makes Furnaces Different at 6,035 Feet

Sizing a Furnace for Colorado Springs Elevation

Furnace capacity is published at sea level. At 6,035 feet, output drops roughly 4 percent per 1,000 feet, which means a nominal 80,000 BTU furnace delivers meaningfully less usable heat here. We perform a load calculation based on your square footage, insulation, window area and orientation, ceiling heights, infiltration, and duct layout, rather than matching the model number on the old unit. Oversizing is the most common mistake we correct: an oversized furnace blasts, satisfies the thermostat quickly, shuts down, and leaves cold rooms and noisy cycling behind.

Efficiency Levels and What They Actually Cost to Run

An 80% AFUE two-stage variable-speed furnace sends about 20 cents of every fuel dollar up the flue but costs the least to install and reuses many existing metal vent systems. A 96% AFUE condensing furnace recaptures exhaust heat and requires PVC venting and a condensate drain, saving a meaningful amount over a long Colorado heating season. A 98% AFUE modulating furnace adjusts its flame in small increments so the house holds a steady temperature instead of swinging, which is what most homeowners actually notice day to day. Installed pricing starts at $4,500.

Venting, Combustion Air, and Code in El Paso County

Replacement is not just swapping a box. Condensing furnaces need correctly sloped PVC intake and exhaust with proper termination clearances from windows, doors, and grade, plus a freeze-protected condensate path. Orphaned water heaters left on an oversized flue after a furnace upgrade can backdraft, so the common vent must be resized. All work is permitted and inspected through the Pikes Peak Regional Building Department under license #26745, and we perform a combustion analysis at startup to verify the furnace is burning cleanly at altitude.

Dual-Fuel: Pairing a Heat Pump With Your New Furnace

Colorado Springs has a long shoulder season where outdoor temperatures sit in the 30s and 40s. A heat pump moves heat efficiently in that range, and your gas furnace takes over below the changeover point when gas becomes the cheaper fuel. The result is lower operating cost across the year plus whole-home air conditioning from the same outdoor unit. Heat pump systems start at $6,500 and complete heating and cooling systems start at $10,400 installed.

Colorado Springs Homeowners Recommend Strong

"I can’t recommend these guys enough. They really took care of me at the moment that I needed it they helped me arrange financing for a new furnace and Jesse came to work on my furnace area and he is a charmer. You will love these guys and you can’t be having veterans work on your equipment. If the Air Force had a saying like the Marines I’d use it right now."

"Could not be happier with the service I got from Strong. I got a full heating and ac install in a house that never had AC. From Asia’s help scheduling, Steve’s advice on maintenance and Riley’s immaculately clean work installing the system it was a great experience . It all runs great and the price was way better than any other estimates I got. Highly recommend using them!"

Frequently Asked Questions

How much does furnace replacement cost in Colorado Springs?

Our current furnace installation pricing starts at $4,500. The final price depends on size, efficiency, venting, electrical work, duct modifications, and site conditions.

What is included in the $4,500 starting price?

The starting installed price includes equipment, standard labor, taxes, and fees. Final pricing is confirmed after a free in-home evaluation.

How long does a furnace replacement take?

Many straightforward replacements are completed in one day. Venting, duct, electrical, or access changes can require more time.

Do you offer furnace financing?

Yes. Financing options are available for qualified homeowners, subject to approval and current program terms.

What furnace efficiency is best for Colorado Springs?

Three levels cover most homes here. An 80% AFUE two-stage variable-speed furnace is the budget-friendly choice where an existing metal flue works well. A 96% AFUE condensing furnace cuts fuel use meaningfully over a long Colorado heating season. A 98% AFUE modulating furnace adjusts output in small increments for the steadiest temperatures and quietest operation.

How does altitude affect furnace sizing and BTU output?

A furnace loses roughly 4 percent of its rated output for every 1,000 feet of elevation, so a unit rated at sea level delivers noticeably less heat at 6,035 feet. Sizing by the old model number instead of a load calculation is the most common reason replacement furnaces underperform in Colorado Springs.

How long does a furnace last in Colorado?

Most gas furnaces here last 15 to 20 years with annual maintenance. Long heating seasons, dry air, and heavy cycling during temperature swings mean Colorado furnaces generally age faster than furnaces in milder climates.

Do I need new ductwork with a new furnace?

Usually not, but we inspect it. Undersized returns, crushed flex runs, and leaky joints choke airflow and will make a new furnace short cycle. If we find a restriction, we show you the measurement and quote the correction separately so nothing is hidden.

Should I replace my furnace and air conditioner at the same time?

If both are near the end of their lives, replacing them together is usually less expensive than two separate jobs and guarantees the blower and coil are properly matched. Our complete system packages start at $10,400 installed.

Are furnace rebates available in Colorado Springs?

High-efficiency gas furnaces and heat pumps frequently qualify for utility rebates. Programs change each year, so we confirm what your specific equipment qualifies for during your free in-home estimate.

Is a heat pump a better choice than a furnace here?

For many Colorado Springs homes, a dual-fuel setup pairing a heat pump with a gas furnace gives the lowest running cost: the heat pump handles mild weather, and the furnace takes over in deep cold. We will price both options so you can compare.
