I bought this unit for a bedroom over my garage. It moves a lot of air and keeps the room warm or cool when need. However, it has an annoying rattle that appears to come from the vent. I have tried to quiet it by stuffing small pieces of cardboard between the gaps.

This AC/Heat unit was bought for a tiny house. It doesn't heat well enough to warm even close to the unit. The AC worked pretty well this summer. The unit just went out. It was only 1 year & 1 mo old. It glowed and then stopped working. Save your money - don't buy this thing.

I purchased this window air conditioner to replace a similar unit already installed. This new one is quiet, has additional features that the old one did not have, and is functioning perfectly. The instructions were beyond adequate.

Over the years, I have grown to like this brand. My first product was a LG TV, and it lasted over 10 years, until lightning hit it. Ended up getting another one, and it is as good, or better. Now, to the AC. At first, it seemed to be a little loud, mainly when the compressor came on.

We bought this unit to replace one just like it that we had for about five years. This unit, like the one before it, works just as it was described. A simple cleaning of the filter and unit maintains it working. It easily changes from AC to Heat and in our Texas weather, that is pretty often.

Great heater!! We haven't had to use the AC yet but this puts out a lot of heat and get our room toasty warm in a few minutes. Great buy :)

Bought this unit for a 16x30 unfinished cabin that I’m living in while working on it. I have insulation on all the walls but ceiling is unfinished. I’m on a prepay account right now and this unit has cut my bill in half and is very efficient in keeping it cool even in the Texas heat!!

I installed through the wall to heat and cool a small house. works perfectly ! I am impressed how quiet running it is.

I bought this unit to keep team members safe during the heat that Texas always delivers during the summer. This unit was enjoyed by hundreds of our team members to help from experiencing heat exhaustion and it worked great.

Keeps our small house comfortable even on the coldest nights. Haven't tried it during the summer yet.
