Air Conditioner

Have you heard about ductless split or mini-split air conditioning systems? A mini-split system is a cooling system that allow you to control the temperatures in individual rooms or spaces.

Mini-split systems have two main components — an outdoor compressor/condenser and an indoor air-handling unit. They usually require only a three-inch hole through a wall for the conduit. This conduit houses the power and communication cables, copper tubing, and a condensation drain line, linking the outdoor and indoor units.

Mini-split systems are not only great solutions for whole home or new constructions but make good retrofit add-ons to houses with “non-ducted” heating systems. They can also be a good choice for room additions where extending or installing distribution duct work is not possible. Mini-splits are also great for energy efficient new homes that require only a small space conditioning system. A ductless system is a very economical cooling solution for a smaller area or a space without existing duct work.
