Experience true individual comfort. Ductless Mini-Split systems
are the perfect solution to a variety of installation challenges.
Ductless Mini-Split units eliminate the use of ductwork, allowing
installers the ability to place these units in locations that were
previously considered impractical or impossible due to
additional ducting and cost associated with installing a regular
unit. Ductless Mini-Splits consist of two parts, an outdoor unit
and an indoor unit, similar to regular split units, but much
smaller in size. The outdoor and indoor units are connected to
each other by refrigerant and electrical lines. They run together
with a condensate drain line through a small hole in an exterior
wall, generally 3 inch in diameter or less. In addition to
eliminating the need for ducting, another great advantage of
Ductless Mini-Split systems is true zone control. The indoor fan
coil unit is dedicated to the room being conditioned, allowing a
temperature and humidity level to be kept in a specific room,
separate from the rest of the house or building.
