Wall Mount Indoor Air Conditioner

Fan Features
Natural Air Flow

Air is directed downward in heating mode and angled upward during cooling mode so the room feels more comfortable, faster.

Ultra Quiet Operation

The cross-flow design of the indoor fan creates an ultra-quiet, yet powerful air flow into the room.

4-Way Auto Swing

Louvers will automatically move up/down and left/right to maintain a uniform room temperature.

Surge Cool/Heat

Allows quick cooling/heating. In this mode, the air conditioner will operate at 100% for 30 minutes to cool/heat the room rapidly.

Dehumidifying Mode

The system will adjust set point for maximum dehumidification.

Sleep Mode

Auto Restart

Auto restart function allows system to resume with previous settings in the event of a power shutdown. (Power supply must be restored.)

Self-Cleaning Indoor Coil

Warranty Info

Warranties on mini split air conditioners only include parts and do not include labor. The licensed HVAC Technician who installs your air conditioner should always provide you with a labor warranty (preferably for at least a full year to compliment the manufacturers' parts warranty).

AJ Madison will only finalize a Mini Split (Ductless Split System) purchase with an authorized HVAC Technician. AJ Madison recommends the installation of a mini-split system to be performed by a trained and qualified HVAC technician with the proper knowledge and background. A trained technician will be able to judge the best location for the air handling (evaporator) unit and also the correct size for the area the unit will heat and/or cool. For assistance with all your technical needs please contact our technical department at

Should you experience an issue during the installation or the initial startup of a unit please do not contact the manufacturer. You should have the technician that installed your system contact either AJ Madison or the manufacturer. We cannot accept any service or warranty calls from anyone but a licensed HVAC technician. We have a full technical support team available to help you throughout the installation process.

AJ Madison, Inc. cannot be held liable for improper installation and operation of any product purchased from our company. Should a warranty issue arise in which parts will need to be replaced, an installation receipt will be required along with your AJ Madison sales receipt. Failure to provide a receipt or invoice may result in the warranty not being honored.
