Are ductless air conditioners more energy-efficient than central AC?

Yes. Ductless mini-splits are more energy-efficient than many central AC systems. They have no ducts, so there are no duct losses. Zoned heating and cooling lets you condition only the rooms you use. Multiple indoor units can connect to one outdoor system, each with its own thermostat. Installation is easier and does not require modifying your home. Regular maintenance helps keep efficiency high and manufacturer warranties intact. This approach works well for homes in Novato and San Rafael.
