Product overview
ACiQ Platinum air handlers can be used with any ACiQ Multizone condenser or the Platinum Single Zone condenser to create a highly efficient Hyper Heat system. This air handler can handle small to medium sized rooms using adaptive technology to constantly monitor and maintain your ideal temperature no matter what the weather outside.
The ACiQ-09W-HH-MD air handler includes a soft LED display on the front of the unit, giving you information at a glance. The display shows the room's temperature by default, but it can also show temperature setpoint changes and mode changes. To ensure your unit runs properly throughout its lifetime, the display will also show any error codes from its self-diagnosing control board, which can be switched off if desired. The included smart remote can show these notifications on its built-in LCD display as well.
ACiQ is WiFi ready! The wall mounted air handlers come with everything you need to control your home's heating and cooling via smart device (iOS or Android) from anywhere in the world. ACiQ is also compatible with Amazon Alexa and Google Assistant.
Please note that in order to function, this air handler must be installed with a condenser and other installation equipment, available at an additional cost if not already included in this product bundle.

Traditional wall-mounted air handlers are the most popular ductless choice due to low cost and ease of installation. Wall mounted units are located high on an outside wall, with refrigerant lines and condensation drain hose exiting the back through a 3" wall penetration. Return air is brought in through vents in the top of the unit, and cooled or heated air exits the lower front through a sweepable louver. Wall mounted air handlers are WiFi compatible and can be controlled by the free NetHome Plus app or by voice assistants such as Alexa or Google Home.
In addition to the handheld or wired remote that is already included, wall mounted units are WiFi ready, and can be controlled from anywhere with a free app on your tablet or smartphone.


Every ACiQ system is precision engineered to quickly achieve set temperature and hold it there, no matter what the weather is outside. With whisper quiet indoor and outdoor units, ACiQ never intrudes on your peace and quiet.

So, so extremely happy with my mini split system. My boyfriend had it installed in just a couple of days and didn't seem to struggle with directions. He did watch several how to videos online and I think that helped a lot. The only issue we encountered was bot understanding that some "master" valve (??) needed to be opened for a setup with multiple indoor units. The directions didn't clarify that and the indoor units weren't blowing cool air at all. I went to the website to send a help chat at almost 9 pm, thinking I'd get a response in the morning. However I recieved an auto generated AI type response based on what I said the problem was. The response gave specific troubleshooting ideas to check and that's what actually gave us the answer as to what was wrong! It was kind of amazing, actually! The system is up and running and saved us during some extreme heat temps! Never looking back, so worth it!!!!
We installed our Mr. Cool Mini Split in an area of our home that is either too hot in the summer or too cold in the winter. Its made a huge difference so far this summer and we are looking forward to seeing how it does this winter when it gets cold out. Its very quite in the room its installed in. You can barely hear it running. So far very happy with it. The install was not bad at all just had some help with the electrical as it is an older house and we were not feeling very confident about doing that ourselves. Over all very pleased with our purchase and will most likely be buying another for our office building.
Certainly the pre-charged lineset takes a lot of the guesswork out of the installation. I chose to torque my connections, and yes you can use an automotive Torque wrench. You have to weld an old socket on the end of an open ended wrench and keep the modified wrench at 90 degrees to your torque wrench handle, then set 35 ftlbs on the torque wrench and 20 for the small connection. made a custom rack to run my linesets on as shown in the photo.
Did not use Mr. Cool, but ordered Daikin through Chill Mini-Splits. All communications were excellent. When we had a sudden problem arise, Devin was able to help us out immediately and was great! Now that they are installed, we are so happy with the quality of the product. Would highly recommend!
Not too hard to install and works wonderfully! Customer service /tech support was soooo helpful and friendly when I couldn’t get the app to work. We got it figured out though!
