Duct Free Systems

Duct free heating and cooling systems make your home's individual rooms or other small spaces more comfortable.  Remember, just like whole-home systems, the higher the SEER and HSPF ratings, the more efficient they will be.

Ductless mini splits, including ductless air conditioners and ductless heat pump mini splits, can fit in any space, even where traditional HVAC systems don't. With their virtually endless configurations, ductless heating and air conditioning systems deliver comfort with minimal visual impact. Unlike traditional central air conditioning and heating systems, ductless heating and cooling systems come in all shapes and sizes, and don’t require ducts inside your walls. These wall mounted air handlers are flexible and work wherever you need them.
