Rated 4 out of 5 by 4 reviewers.
Rated 5 out of 5 by Very good purchase I built a 14 x 30 addition and needed something to cool and heat the room , i went with this model after looking at all the ones that are out there . Im glad that i did it cools the room great and i have had the chance to use the heat for a few days so fare ,and it worked great ,its so quiet .that somtimes i had to look to see if its was on .. it was very easy to install, i went with the optional line set ,and im glade i did .. I hope this helps anyone looking for a unit like this . 9/14/11
Rated 4 out of 5 ontime/easyinstall The unit arrived on time and in good shape. The install took just a couple of hours. I did hire an A.C. guy in to check out the install and to make sure it was charged O.K. 12/15/12
Rated 4 out of 5 by Good value Works as expected. They could make the installation instructions more detailed. 3/10/13
Rated 3 out of 5 Nice Unit But Louder than Previous Unit This replaced a Soleus 12K unit we bought 9 years ago. The compressor failed, but during those 9 years the unit performed well and was quiet (referring to the air handler). This new unit, for some reason is bigger than the one it replaces, which causes a cosmetic issue such that it is no longer centered on the wall between the 2 windows. The original hole (necessary for the routing of the liquid refrigerant lines) created for the 1st unit could not be moved, so I had to install it there, but the overall air handler is longer, so it is no longer centered. Additionally, while the unit operates well I have noticed the air handler is not as quiet as the 1st unit we had, which is disturbing. During installation, I noticed Soleus cut corners on the quality of the unit. The original unit seemed to be built better, the new one is made more cheaply, even the backing plate/mount for the air handler is quite flimsy compared to the old one. Lastly, the outside compressor cover that houses the electrical only has one screw holding it whereas the original cover had three screws. The routing of the electrical conduit sheaths torque the cover to one side because of this. Had they put 3 screws in the cover, this would not have been an issue. It is sad to note that the Chinese units are getting more expensive, but at the expense of cheaper quality manufacturing. I can only hope I get the same length of service I got out of the last one... 6/6/14

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.
