The remote control for this unit is great. It even has a button to turn off the display on the unit. That’s a great feature for a bedroom if you prefer to sleep in total darkness.The noise level on this unit is pretty low compared to the power it puts out. If you have a problem with noise there is most likely an issue with the way it was mounted. Mine has plenty of insulation between the unit and the wall sleeve on all sides and that keeps the metals from clanging together.It’s not really the easiest unit to install just because there are a lot of things to consider and if you don’t install these professionally you may spend hours just researching which wall sleeve works best with this unit. You also need to be sure the sleeve and the unit slope down toward the outside of the building. I initially installed the sleeve level with the unit tilted back, but because the sleeve was level all the water was standing in the bottom of the sleeve and eventually seeping out the front. I had to pull it all out and redo everything with the sleeve tilted back at an angle that would allow it to drain.Once it’s properly installed this has made my largest room my most comfortable room. It keeps the room around 70 all day in August without having to work too hard. That’s the main reason I bought it. Because it performs its main task so well and because the remote is so good I would give this five stars overall.

This was a replacement for a 20+ year old inefficient through the wall AC unit. We decided to upgrade to an AC unit with heat as that large room was often chilly. I am totally satisfied with the cooling and supplemental heating abilities of this unit. Very heavy so it was a 2-person install but the associated sleeve made the installation easy and looks professional. Very happy with the purchase!

I gave the warmth one star because I bought this product in the beginning on summer. So not sure how well the heat works A/C is great. It does make noise but nomorw than any other wall unit I've owned

Quiet Cool is Cool, but not quiet. The machine runs and cools very well. However, the name is a misnomer. It is not quiet, it is very loud. If you seek a quiet machine than don't buy it. Emerson Loud Cool.

Fits into the old LG A/C sleeve. Quiet but also provides nice white noise.So far my only issue is that the morning, sunlight comes right through part of the inner A/C grill, even though my husband completely sealed the outer perimeter with black caulk. Thus, all that we spent on blackout window coverings is partly going to waste. I will call Emerson about this to see if they have heard about this and have a solution.UPDATE: March 2020: Starting to turn itself off whether it’s on Fan or Cool. Made sure the TIMER wasn’t engaged. No strange noises or smells or malfunctioning — it just STOPS — THEN IT RESTARTS ON ITS OWN...

I replaced the old unit from an apartment after it stopped working. The build and design of this unit is great. The remote control features are a nice bonus in addition to the what appears to be a built in surge protector on the end of the power cord. After several months of usage, no complains.
