How energy-efficient are ductless heating systems compared to traditional units?

Ductless mini-splits are more energy-efficient than traditional central heat because they avoid duct losses and let you heat only the rooms you use. They deliver warm or cool air directly into zones with individual thermostats. This zoning reduces run time in unused areas. There is no energy loss from long duct runs found in forced-air systems. Compact indoor units offer flexible placement. These systems are ideal for add-ons and garages in Novato and across Northern California.[0]
