A ductless mini-split is like a conventional air conditioning system that can both heat and cool but does not require duct work within your home. These systems are great for sun rooms, bonus rooms, basements, garages, and new renovations. The ductless mini-split systems require minimal penetration to the exterior of your home. They are safer than using a window unit because they do not provide access into your home. These energy efficient systems come in various sizes to fit your need and save you money all year long.
