Product overview
Inverter Heat Pump - The ACiQ-36-EHPB 3-ton central inverter heat pump utilizes inverter technology to convert AC power to DC, allowing the compressor to adjust its speed. This enables the system to modify its BTU output based on the current demand, providing efficient and adaptable performance throughout varying weather conditions.
Intelligent System - Equipped with advanced sensors, this system monitors indoor and outdoor air temperature, duct pressure, refrigerant temperature, and overall system performance. During the initial startup, it enters a learning mode, optimizing future operations for maximum efficiency by collecting and storing data.
Adaptive Sizing - With its self-adjusting inverter design, the ACiQ-36-EHPB can be sized based on your heating needs. Standard heat pumps may cause discomfort during summer when sized for heat, but this unit automatically adjusts to function like a smaller unit, ensuring ideal cooling performance without excess humidity.
Boasting an efficiency rating of 16.9 SEER2, the ACiQ-36-EHPB provides versatile comfort across a range of climates. Reliable comfort with variable output that eliminates short cycling for lasting efficiency. Use our size calculator BTU Calculator to determine the demand for your home.

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!
