What is a Ductless Mini-Split?

A ductless mini-split is a special type of HVAC system that provides individual comfort without requiring ductwork. These systems consist of an outdoor compressor unit and one or more indoor air-handling units, which cool the air similarly to a central air conditioner. However, each indoor unit only cools one zone of your home.

Ductless mini-splits are ideal for various spaces, including older homes without ductwork, room additions, apartments, or commercial buildings where traditional HVAC systems are impractical. They’re excellent at providing zoned heating and cooling, allowing you to adjust temperatures independently in different areas for enhanced comfort and energy efficiency.

Whether you’re retrofitting an older home, adding rooms, or seeking a space-saving HVAC option, ductless mini-splits can provide the tailored comfort solutions you want.
