Ductless Split Systems Air Conditioning
No ductwork No problem. Incredibly quiet, sleek and energy-efficient, ductless split systems are the smart way to cool rooms without ductwork-even those without windows or exterior walls. And new for 2011, high-efficiency 115V models with Inverter Technology!

Why choose wall-mounted
If you have one or more rooms without exterior walls or windows, a wall-mounted ductless split system will work beautifully. The indoor air handler is sleek, unobtrusive and quiet. You need only a 2" clearance from the ceiling, so you'll have lots of placement options. All systems come with a remote control, so even units high on the wall are easy to operate. There's also an optional wired, wall-mounted controller for models over 18,000 BTU.

Product Reviews
Rated 4.7 out of 5 by 6 reviewers.
Rated 5 out of 5 by I should have buy this unit a long time ago for some items the french guide translation isn't too good so I had to refer to the english one to be sure about the instructions. 5/24/12
Rated 5 out of 5 Mini Split AC I was fearful of ordering this on line. It came on time and was easy to install. The service was very good. You will not even realize the ac is on except that the room is cool. We love it and everyone who has come to see it flips at how quit it is. It looks fine on the wall. 5/9/11
Rated 4 out of 5 by Smart Purchase I bought this unit for a room that was an addition to my house. The original house HVAC could not handle the additional space. I installed this 9000btu unit with the short line kit in approximately 6 hours...not including trips to the hardware store. Installation was fairly easy once you overcome cutting a 2-1/2 inch hole in an exterior wall. You will need a vacuum pump to draw down the refrigerant lines. It was well explained in the instuctions. I would suggest a wall bracket to mount the outdoor compressor. It helps the aesthetics. I would also suggest a conduit for the refrigerant lines, electrical line and drain line. Also for aesthetics. The room cooled immediately and maintained temperature. The compressor is quiet. Make sure the drain line is always draining downward. This unit removes a lot of moisture from the room. 7/3/12
Rated 5 out of 5 by Super Efficient Unit - DIY beware While I'm no All American Handyman, I am fairly skilled at most home projects. This one, however, took quite some time and left me scratching my head at several times with the included instructions. Top challenges: 1) Running the line set is challenging if you are running through walls and ceiling space. If at all possible go with the shortest run possible. The 35' line set is a bear to work with. 2) Line set connection says to use some sort of oil between the connections. Still to this day after googling around, I don't know what this is and forgoed it. Seemed no to make a difference. 3) The drain hose from the indoor unit to outdoors was a challenge to figure out. My suggestion (and what I used) was a dishwasher drain hose. This has the rigidity needed no to bend. I also moved the drain side so that it ran straight into the wall. After reading the instructions you get a fear about draining to outside if you live in a cold weather climate. My recommendation is that this is better than draining to a crawl space which can attract termites and cause mold. Keep in mind the 1/4" drop every foot for proper water flow. 4) When you buy a pump and hose set to pump down the line set, you will need a 3/8 R410a adapter. Nowhere is this clear in the instruction manual and it isn't a part your local mega home improvement center will sell. 5) When you get everything installed and first turn it on, it takes several minutes for the unit to get up to speed (warming or cooling air at a very low speed). I thought the unit was broken and flipped the breaker because I thought nothing was happening. THE UNIT RUNS EXTREMELY QUIET and at low speeds most of the time. 6) Remote only works when aimed at the unit. It's infrared, not RF. So with it mounted on the wall, you'll need to remove it, aim it at the unit then put it back. More of a training issue for others in the house. Hopefully the notes here will help others as they install their units. 12/11/12

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
