Ductless mini split systems are increasingly popular in Northglenn for homes that lack existing ductwork, room additions, garages, and basements. At 5,280 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.
Northglenn's housing stock is primarily 1960s-1980s construction, making it one of the north metro areas with the oldest HVAC systems. Many homes still run original furnaces that are 30-40 years old — well past their safe operating life. The city's flat terrain provides no wind protection in winter.
