Product overview
Inverter Technology - Inverter technology changes AC power to DC, allowing the compressor inside your condenser to speed up and slow down. This allows the system to self-adjust BTU output based on demand. As the weather changes, so will your system output.
Learning Condenser - Equipped with advanced sensors, this condenser monitors air temperature inside and outside, overall system performance, duct pressure, and refrigerant temperature. During the initial startup, it enters a learning mode to optimize efficiency for future operation by continuously gathering and storing critical data so future startups and run cycles will be at max efficiency.
Size for Cooling - The self-adjusting inverter design allows the condenser to change its output based on cooling demand, keeping you cool and comfortable. For optimal performance, pair the ACiQ-30-AC unit with the ACiQ-30-ACL coil.
With an efficiency rating of 15.2 SEER, the variable output ACiQ-30-AC will keep you comfortable across a wide range of conditions. Use our handy size calculator BTU Calculator to determine the demand for your home. This system can operate anywhere from 12,000 BTU to 30,000 BTU without short cycling.

If your existing condenser has reached the end of its life or isn’t keeping up with your cooling needs, ACiQ’s inverter AC-only models are an excellent replacement choice. They’re designed to fit standard line sets and connections, making the switch seamless and straightforward—no complicated retrofitting required.
With their improved efficiency, lower noise, and reliable cooling, ACiQ inverter models bring modern comfort and energy savings to your home without the hassle of a full system overhaul.
ACiQ inverter models offer all the benefits of advanced variable-speed technology at a price that competes with traditional condensers—no high upfront cost to worry about. Plus, the improved efficiency means you’ll save more on your energy bills month after month, making it a smart investment that quickly pays for itself.
Every ACiQ condenser features a variable inverter twin rotary compressor, lowering wear and increasing performance. Compare specs against other brands in the same price category, and you will agree, ACiQ is the best value.


ACiQ AC-only inverter units arrive pre-charged with R410A refrigerant, supporting up to 25 feet of lineset. This means faster, easier installation—saving time and money while providing reliable, efficient cooling.

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!
