In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Nice couch for the price
Color: Black, Size: 7 Seat, Color: Black, Size: 7 Seat
Nice and firm I was able to put it up by myself in about three hours. It is really cute The material is soft. I really like it. It was super easy to put together. It came in 4 different boxes, I was worried because people said they got the boxes on different days luckily, I got the whole couch the same day and put together that night. I’m happy with this purchase. Can’t wait to sit on it and watch TV. I just wanna give it a few days to let the seat cushions recover.

Love the storage and pull-out
Color: Dark Grey, Size: 7 Seat, Color: Dark Grey, Size: 7 Seat
The size is great and fits nicely in the corner without feeling too bulky, but still has plenty of seating. The dark grey color looks clean in person and matches my space really well — not too light, not too dark. The pull-out part is honestly one of my favorite features. It slides out pretty smoothly and turns into a big lounging area or bed. I’ve already used it to relax and watch TV and it’s really comfortable. The storage compartment is also bigger than I expected — I can fit blankets and a few extra things in there easily, which helps keep everything more organized. Comfort-wise, I’d say it’s medium-firm. Not super soft like a cloud couch, but still comfortable enough for everyday use. The cushions seem to hold their shape pretty well so far. Assembly took a bit of time and it’s easier with two people, but overall it wasn’t too complicated. Once it’s set up, it feels pretty sturdy. If I had to nitpick, the cushions do shift a little after sitting for a while, so you may need to adjust them occasionally. But for the price, I think that’s pretty normal.

very nice for the money
Color: Dark Grey, Size: 5 Seat, Color: Dark Grey, Size: 5 Seat
Very comfy. The color is perfect. The back pillows do shift when leaning against them but a throw pillow or two helps comfort. The material is soft. And it was fairly easy to assemble with 2 people.
