While ductless mini-split equipment can have a higher upfront cost than central HVAC equipment, you will experience multiple cost-saving efficiencies throughout its lifespan: The U.S. Department of Energy found that duct losses can account for more than 30 percent of HVAC-related energy consumption. Duct losses don’t occur with mini-splits. With zoned heating and cooling, you can turn off or turn down units when you aren’t in a certain zone. Ductless systems’ longer lifespan means you don’t need to replace them as often.
