 The Comfort Aire wall mounted ductless mini-split heat pump systems (heating and cooling) are designed to be whisper quiet. The design keeps operational sound outside with the condenser while the indoor air handler remains much quieter. The sleek appearance of the indoor air handler blends with any decor. These systems are ideal for locations where it is too expensive or impractical to install ductwork, or where window air conditioning units cannot be used. They are easily installed in bedrooms, sun rooms, offices, arena skyboxes, and historical buildings.


  • Whisper-quiet operation
  • Attractive wireless remote control
  • Dehumidification mode reduces water vapor
  • "SLEEP" mode provides suitable sleeping environment
  • Timer which can be used to save energy
  • Auto operation adjusts fan and mode to maintain the selected room temperature
  • Three minute time delay at start protects the compressor from short cycling
  • Auto restart reverts to programmed setting after a power failure
  • Uses environmentally friendly R-410A refrigerant
  • Simple installation requiring a hole in the wall less than 3 inches in diameter for connections between the indoor and outdoor sections
  • Hot start prevents discharge of cold air during heat mode.


(Note: These heat pumps will not operate in heating mode when outdoor temperature is below 19.5 F degrees.)

Complete your system by selecting a line set from the "Accessories" tab above.  Line sets come in 15 foot, 35 foot, and 50 foot lengths.

Inside air conditioning systems are liquid/gas refrigerant. There are two types of this refrigerant available for use, R-22 (more commonly known as Freon), and a newer alternative R-410A.

An air conditioning system does not consume refrigerant, but reuses it. As long as there are no leaks in the refrigerant circuit, there is no need to ever add more refrigerant to an air conditioning system.

Although R-22 is an effective refrigerant, if it is released into the atmosphere it can contribute to the depletion of the Earth’s ozone layer. The EPA has mandated the phasing out the use of R-22. It is being replaced by R-410A.

As of 2010, manufacturers are required to make all new air conditioners with R-410A. However, R-22 is still available for sale in existing pre-2010-manufactured equipment, and for use in servicing existing R-22 equipment. By 2020, R-22 will no longer be manufactured, but will still be recycled and available for sale.
