What Is a Mini-Split?

A mini-split is a heating and cooling system that doesn’t use traditional air ducts.

Instead, it has:

  • A wall-mounted indoor unit
  • A small line connecting the two

Since no ductwork is required, mini-splits are perfect for garages, workshops, and home additions.

A ductless system offers several advantages:

  • Energy efficient
  • Quiet operation
  • Easy installation
  • Individual temperature control
  • Compact design
  • Low maintenance

Instead of cooling the entire house, the system only cools the garage, helping reduce energy consumption.
