Types of ductless ac


Air Conditioner & Heat Pumps Indoor Units that mount flush to the wall of the room. Sleek, styling design with whisper quiet operation. Usually mounted on outside wall of the room for easier connection to outdoor unit – only a 3” hole needed to pass refrigerant tubing and communication wiring that connect the indoor ductless unit with quiet and efficient outdoor unit, in many cases located right outside of the wall. The wall mount indoor unit often could be installed on inside partition, but this complicates the installation and future maintenance. When a ductless wallmount unit is installed in such manner, the condensate drain, as well refrigeration tubing and wires could be passed inside of the partition down to the space below. If the installation should be done on first floor of the house, then the piping and wiring can be passed to the basement and then outside to outdoor unit. This also allows condensate drain to be wasted in the basement slop-sink or any other  suitable drain. More info
