Ductless mini split systems are increasingly popular in Lone Tree for homes that lack existing ductwork, room additions, garages, and basements. At 5,850 feet elevation, mini splits have an advantage over gas equipment — no combustion adjustments needed, and the heat pump technology works efficiently in both heating and cooling modes. We install single-zone ($3,000-$5,000) and multi-zone ($5,000-$8,500) systems from top manufacturers. Every installation includes proper mounting, electrical connections, refrigerant line installation, and commissioning.
Lone Tree's elevated position at 5,850 feet and modern construction (mostly built 2000-2015) means high-efficiency systems are common but now approaching their first major service intervals. The area's large homes (many 3,000+ sq ft) require properly sized 4-5 ton systems.
Our technicians serve all Lone Tree neighborhoods including RidgeGate, Heritage Hills, Carriage Club, Lone Tree City Center. Whether you're in a newer development or an established neighborhood, we have the expertise and licensing to handle your HVAC needs.
