Super quiet on the inside and the outside inverter also. Very pleased with the overall look and of course it feels great! I can’t wait to come back and share more great news in the winter !!
18K dual-zone unit works great - indoor evaporator units are nice and quiet and put out lots of cold air. The outdoor condenser unit is also nice and quiet. You can barely hear the compressor running - the fan is very quiet, but it is louder than the compressor! These mini-splits are the way of the future! Installation of the 240VAC power and gas tubes was very easy. I would buy this again in an instant. The 2 zones are on 2 different floors; zone 1 is about 750 square feet, and zone 2 is about 900 square feet, and this keeps both zones cool just fine. The Della video in this listing is a great summary of the installation steps.
Installed this unit in a rental a couple of months ago. We live in the northeast, so we have extreme temperatures, both hot and cold. Even when the temperature was around zero degrees Fahrenheit, this unit still kept the apartment at 74 degrees with no problem. It wasn't difficult to install. We did have a professional come and take care of the refrigerant. We are happy with the purchase.
Installed everything myself (with the help of my wife). Very easy to follow instructions. Love the way it heats and cools. Haven't got to the hot summer days yet, but will post information if anything changes! Thanks Della!
I never installed a mini-split system before, this was a DIY project for me and it was a bit harder than I expected but well worth it. For the smaller 1/4in line set, the manual gives a torque value of 15 - 20 newton-meters but torquing it to 20 newton-meters keeps breaking the flares, so the highest I could torque it to was 17 newton-meters. This dual zone 12 + 12 18K BTU system is blowing cold air in scorching Arizona, only time will tell how it holds up but so far it's a great value for the price.
Working very well. The condenser is so quiet you don't know it's running. Inside the fans are barely noticeable. Did great during cold weather and is cooling nicely.
I recently purchased the 208-230V Cools Up to 1100 Sq. Ft Wifi Multi Zone Mini Split Air Conditioner and I'm thoroughly impressed. The quality of this unit is exceptional, which is evident from its sturdy build and efficient cooling capabilities. Installation was a breeze with the included 16ft Installation Kits, and I had it up and running in no time. The noise level is impressively low, barely noticeable even when it's running at full power. Additionally, the temperature it achieves is exactly what I needed - it cools my space quickly and maintains a comfortable environment. The multi-zone feature is a game-changer, allowing me to cool multiple rooms with ease. If you're looking for a top-notch, fast-working, easy-to-install air conditioner, I highly recommend this model.
