Quietest air condition ever. I was holding my breath when I ordered this AC for a sliding glass window in our sunroom(about 350 sq ft) that was 19.25" wide (one side). Yes, we had to remove one side of the slider and install a panel above the unit. The AC fit almost perfectly and the install was easy. (They even provide little custom cut foam pieces for the top of the unitbto go between the unit and the side filler pieces). We let it set for 24 hours, as suggested in several text messages. Plugged it in and turned it on. It ran thru it's system check and started cooling. It wasn't a ghastly hot day so the temp in the room was in the mid 80s. Within 10-15 quiet minutes, the sunroom was a very pleasant 80° on it's way to 75°. When I used on a ghastly hot day, the sunporch temp was 94. It took it about 30 min to get room to a tolerable 84 with fan on low. When I increased the fan speed, it got down to 80 quickly. When you turn it on it automatically sets to 75. SO QUIET - both inside and out. The buttons and readout on the front are large and intuitive. I'll keep the instructions handy because any function other than cooling isn't intuitive. So far, all we have used is the AC, and we couldn't be more pleased. My only suggestion would be to make the bridge adjustable like on some of the other AC's that don't have the inverter technology. (We bought this unit specifically because we wanted the newer inverter technology.) It has adjustable "feet" on the outside to hold the AC in place. Because the house has vinyl siding, we put a board between the "feet" and the siding to prevent damage to the siding (especially when the temps drop.) We would buy this unit again without hesitation.

We are so pleased with Wayfair and the air conditioning unit we ordered. From the delivery, to the ease of set up, to the properly functioning unit, we are so happy with our purchase. It is ideal for our camp to make the hot, humid days so much more comfortable! Wayfair-it was "Just what we needed"! Thank you!

I love it
