A Ductless Mini Split system is an Air Conditioner or Heat Pump system that has an outdoor unit and in door unit. The outdoor unit looks similar to a typical outdoor AC unit. The indoor unit is mounted to a wall or ceiling. The system uses no ductwork and instead has a wall or ceiling mount unit in every room. When not maintained properly, and/or installed improperly, Ductless Mini Split systems can have a very short life span. If properly maintained, ductless mini split systems can last 20+ years.
Proper maintenance is vital to getting a long life out of your ductless Mini Split system, as well as the highest level of efficiency possible. A ductless mini split system that has not been serviced in years will cost MUCH more to operate, and or may not operate at all.
