Short-cycling (turning on and off frequently) is often caused by a dirty air filter, an oversized furnace, or a failing flame sensor. At Lone Tree's elevation (~5,800 ft), combustion air issues can also cause short-cycling. Our technicians diagnose the root cause rather than just replacing parts.
Yes. Our licensed contractors service all heat pump brands including Carrier, Trane, Lennox, Rheem, and Daikin. Heat pumps are increasingly popular in Lone Tree because they provide both heating and cooling efficiently in Colorado's climate.
If your furnace is under 15 years old and the repair cost is less than 50% of a new system, repair is usually the better value.
