What is a Mini Split System?

How does a mini split system work?

A mini split system, also known as a ductless mini-split system, operates on the same principles as a traditional central air conditioning system, but without the ductwork. It consists of an outdoor unit and one or more indoor units, allowing you to control the temperature of individual rooms or zones.

What are the components of a mini split system?

The main components of a mini split system include the outdoor condenser unit and the indoor air handler. The outdoor unit of the ductless mini split system houses the compressor and condenser, while the indoor unit contains the evaporator and fan. Refrigerant lines connect the outdoor and indoor units, enabling the transfer of heat or cool air.

What are the different types of mini split systems?

There are different types of mini split systems, including cooling-only units, heat pumps for both heating and cooling, and multi-zone systems that allow independent climate control for various areas within a building.
