Lone Tree is home base for Mission Mechanical, so when your furnace acts up here, you're calling neighbors. Whether you live in RidgeGate, near Park Meadows, or just off Lincoln Avenue, our techs know these homes and how hard Colorado winters can be on a furnace. Our mascot, Kodiak the bear, is a Lone Tree local too.

Furnace not heating? Call (720) 390-0699. Our office is open Monday–Friday, 8 AM–5 PM, and 24/7 emergency service is available after hours and on weekends.

Signs Your Furnace Needs Repair

  • Cold or lukewarm air from the vents
  • Short-cycling (turning on and off every few minutes)
  • Banging, squealing, or grinding noises
  • Uneven heat or a sudden jump in your heating bill
  • Carbon monoxide alarm sounding (leave the home and call 911 or your gas utility first)

What We Fix

We service all HVAC equipment, whatever the make, including:

  • Igniters and flame sensors
  • Blower and inducer motors
  • Gas valves and burners
  • Control boards, limit and pressure switches
  • Thermostats and wiring
  • Condensate drains and airflow problems

If repair doesn't make sense for an older furnace, we'll say so plainly. If you replace, financing is available. Mission participates in the Xcel Energy rebate program and Colorado Power Ahead, so ask us what may apply to your new system.

Local Furnace Help for Lone Tree Homes

Lone Tree sits at roughly 6,000 feet, higher than Denver. At that elevation there's less oxygen for combustion, so gas furnaces need to be set up and adjusted for high-altitude operation. A furnace that isn't tuned for elevation can burn inefficiently, trip safety switches, or wear out parts early.

We serve homes across Lone Tree on both sides of I-25: RidgeGate West, newer homes in Lyric at RidgeGate east of I-25, and established neighborhoods such as Heritage Hills and Acres Green. If you're near Sky Ridge Medical Center, the Lone Tree Arts Center, Bluffs Regional Park, or the Lincoln and RidgeGate light rail stations, you're right in our backyard.

Big temperature swings are part of life here. A mild afternoon can drop into a single-digit night, so furnaces cycle more often. Dry air, dust, and seasonal wildfire smoke also clog filters faster than many homeowners expect.

Lone Tree ZIP codes we serve: 80124 (west of I-25) and 80134 (east of I-25, a ZIP Lone Tree shares with Parker).

Furnace Repair FAQ

Do you offer emergency furnace repair in Lone Tree?

Yes. We offer 24/7 emergency service. Our regular office hours are Monday–Friday, 8 AM–5 PM, and we're closed weekends for routine appointments. If your heat goes out after hours, call (720) 390-0699.

How do I know if my furnace needs repair or replacement?

If your furnace is under about 15 years old and the repair is reasonable, repair usually makes sense. If it's older, needs frequent repairs, or a major part like the heat exchanger has failed, replacement may be the better value. We'll give you an honest recommendation either way, and financing is available.

Does the altitude in Lone Tree affect my furnace?

Yes. At roughly 6,000 feet, there's less oxygen for combustion, so gas furnaces need to be properly set up for high altitude. Incorrect setup can lead to poor efficiency, safety shutoffs, and shorter equipment life.

What should I do if I smell gas?

Leave your home right away, don't flip switches or use your phone inside, and call your gas utility or 911 from a safe place. Once the utility says it's safe, call us for repairs.

Do you serve both sides of I-25 in Lone Tree?

Yes. We serve Lone Tree homes west of I-25 in 80124 and east of I-25 in 80134, including newer homes in RidgeGate's east side.
