Ductless Services

Ductless or mini-split AC systems can be a great option for people who want to regulate the temperature inside their home or business without having to install a central HVAC system. A mini-split AC system has three primary components: an indoor handling unit, an outdoor condensing unit, and a remote control. These units are very efficient because they blow air directly into a room rather than having it distributed via ductwork.

You can count on us at D6 Air Conditioning and Heating to install, repair, or tune up your mini-split AC system. Many people choose ductless for:

Commercial offices
Garages, basements, and attics
Residential bedrooms
Home additions
Older buildings unable to accommodate ductwork
