What Is a Mini Split Air Conditioner?
Many homeowners in the U.S. are switching to air conditioner mini split systems because they’re energy-efficient, quiet, and easy to install.
A mini split air conditioner is a ductless cooling system that includes an indoor air-handling unit and an outdoor compressor.
Unlike a central air conditioner, a ductless mini split air conditioner does not require ducts — it delivers air directly into each room.

How Does a Mini Split Air Conditioner Work?
A mini split works by transferring heat between indoor and outdoor units using refrigerant lines. The system uses inverter compressors to maintain steady temperature without large power surges.
This technology keeps your home cool in summer and, with a heat pump, warm in winter.
