Mini Split Systems are ductless systems ideal for spaces where running ductwork is not practical or desirable. Single Zone mini splits include the outdoor unit and indoor air handler only. Copper lines and other accessories sold separately. Single Zone Mini Split Systems are great for rooms where you need extra cooling like kitchens, porches and sunrooms, upstairs bonus rooms or where equipment and electrical devices heat things up. Mini splits are economical to install and provide direct and efficient climate control with the convenience of a remote control. Mini splits are available in heat pump or air conditioning (cooling only) configurations. Mini Splits are often much more efficient than traditional split systems, and you can easily turn the system off when climate control is not necessary. These systems use environmentally friendly and efficient R-410A refrigerant. They are pre-charged.
