Outdoor Air Conditioner

Outdoor Air Conditioner

Inverter (Variable Speed Compressor)

Instead of shutting off once the desired temperature is reached, an Inverter compressor continues to operate at low speed to maintain that temperature. The air conditioner is quieter to operate and uses less energy than conventional ACs, which cycle on and off.


Shuts down the indoor fan to prevent cold air from being blown into the zone. Removes frost from outdoor coil when the outdoor temperature is low.


A self-troubleshooting function that makes it easier to diagnose malfunctions, reducing service labor.

Auto Operation

Provides three levels of comfort from which to choose. Temperature and fan speed will set automatically.

Auto Restart

Automatically restarts air conditioner to programmed setting when the electricity comes on after a power failure.

Gold Fin™ Anti-corrosion

All DFS system outdoor air conditioner coils have a corrosion resistant GoldFin™ coating standard from the factory. GoldFin™ will promote sustainable efficiency and coil life by helping to prevent corrosion caused by everyday pollutants.

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.
