You don’t have to tear apart your home to get intelligent cooling. An electric ductless mini split installation is the perfect solution for adding air conditioning to homes that aren’t compatible with traditional HVAC systems or window units.

Ideal for additions, finished basements, sunrooms and bedrooms, Ductless mini split units are gaining popularity for their ability to provide an unlimited number of climate zones via remote control, as well as their remarkably quiet and extremely efficient operation. Ductless mini split installation is quick and easy, making it ideal for the many home situations where a ductless air conditioner is needed.

How it Works

Similar to traditional air conditioning units, a ductless air conditioner operates with two main components: an outdoor compressor/condenser and an indoor air handler. However, true to their name, mini splits differ from traditional heating and cooling systems by operating without ductwork. Rather, an electric ductless air conditioner system delivers air directly to different zones in your home through a small conduit that connects its indoor and outdoor units. The indoor components of a mini split system require minimal installation work and can be mounted anywhere that has access to electricity.

Why Ductless Mini Split Installation?

Multiple Climate Zone Controls

A ductless mini split system allows you to create and control multiple climate zones in your home. Many models can pair up to four indoor units to one outdoor compressor, with each one being controllable for optimal comfort via individual thermostats.


Because ductless air conditioners operate without bulky ductwork, they are less susceptible to leaks that account for up to 30% of energy consumption in traditional systems. This makes mini split systems up to 40% more efficient than conventional HVAC.

Ease of Installation

For many homes with space constraints or plaster walls that don’t allow them to fit larger ductwork used in traditional systems or window units, ductless mini split installation is a flexible, minimally-invasive alternative. The small, simple connections from outdoor to indoor units mean homeowners have choices when it comes to the interior design of their system.

Installation Costs

Due to their more intricate design and need for a trained professional, the initial setup costs of a ductless mini split system are typically higher than that of window units or other non-traditional air conditioning systems.
