Ductless Heat Pumps Why Buy a Ductless Heat Pump? According to ENERGY STAR®, nearly half of the energy used in your home goes to heating and cooling. Ductless heat pumps offer a convenient energy-efficient alternative to conventional heating and cooling systems. Instead of using bulky ductwork, ductless heat pumps use an indoor unit connected to an outdoor unit via refrigerant lines, which are easy to install! According to ENERGY STAR, ductless heat pumps provide many benefits: Allowing for Different Climates for Each Room. Each indoor unit can provide customized heating and cooling — adjustable through wall consoles, remote controls and smart phone apps — in each conditioned space. Cutting heating costs in half compared to conventional electric heating systems. Because they transfer instead of generate heat, ENERGY STAR certified ductless mini-split heat pumps use 60% less energy than standard home electric resistance-based heating systems. Cutting cooling costs by 30% compared to conventional room air conditioners. ENERGY STAR certified ductless min-split heat pumps use more sophisticated compressors and fans that can adjust speeds to save energy.
