I’m very pleased thus far with this unit. The wifi and app seems to work well. I installed in a garage that can reach well over 100 degrees. It required custom install because the only window is a slider. I’m waiting to see how my electric bill compares to the bill prior to install, when I had a different unit that didn’t have the wifi and eco settings, but I’m hopeful it’ll be much lower. The dimensions listed in the manual for through the wall type install are wrong, and this should be corrected. Otherwise the unit is very quiet, and I’m hopeful it’ll last a long time.
