Awesome window AC unit
The AC is working excellently — thank you! Just one note: it makes a weird noise when turning on and off. It only lasts for a short period, and it’s not a problem for me, but I wanted to mention it.

Installed a 18000 BTU Vario Mini Split. All went well with the installation. YouTube videos really helped. My question for support was with using the Remote vs App. I set the temperature on the App and also on the Remote. The Remote seemed to override the App but support let me know the unit takes the last command sent. So if I put the temp at 73 on the Remote and then use the App to set the temp at 75 the unit will be set for 75 but the Remote will still show 73 and vice versa.

Install was easy. Connections for spiral wound refrigerant lines was very easy and kink free due to the spiral winding on them. Very nice feature.
