                  Love ac/heater
                  [This review was collected as part of a promotion.] It is good enough for our vacay cabin in pocono. Ac and heater and ac both works good and it is very company modern looking design. Goes anywhere..

                    AMAZING SYSTEM
                    [This review was collected as part of a promotion.] The box that came is HUGE! Make sure you have a good amount of space in your living space to put this! It is very strong! It does both heating and cooling as well as dehumidifying! A room warms/cools fairly quickly and it is AMAZING

                      Didn’t work with our setup/window. We weren’t able to return it because it was past the 5 day return day. Now we are stuck with something that we can’t use. We still have to find something that will work and pay hundreds more.

                      Much bigger than anticipated
                      [This review was collected as part of a promotion.] When I saw mobile AC, I for sure thought that meant it could easily move from room to room without the hassle of being tied to a window. Unfortunately this needs to vent through a window in order to work properly. That might not be a negative for many, but for the tight space we were hoping to use this in (a bedroom), it’s a bit disappointing. As for the actual features. its large size will cool multiple rooms or a very large space quickly. The smart functions are a great bonus! It is heavy and sturdy, making me feel confident this will last a long time. It arrived in a box almost as big as a washing machine! It’s a big machine, with a lot of power! Perfect for the summer heat!

                        Lot's of water!
                        I've had it less than a week. I have never seen an ac unit produce so much water! The compressor shuts off and runs fan only until it's emptied. Meaning the room never gets a chance to cool down. Running it on dehumidifier fills up a 2 gal pitcher in one hour. (I hooked the hose to outlet valve and just let it run.) Running the air on 75°, I've had to empty the tank every 20 minutes or so. It beeps and compressor turns off when full. I'm in Alabama, I know humidity is high, but dang! It will not turn on compressor until you empty the tank. Returning. I'll settle for a window unit that will empty outside!
