It's particularly noted for its quiet operation and the ability to fit in small spaces, making it versatile for different room sizes.

  • Good Quality
It's only been a month but most days have been hot ones and this seems to have no problem keeping our double wide mobile home cool, it has been cooling the kitchen, dining and living room areas making them very comfortable despite poor insulation of the trailer and manages to satisfy the unit. Now the question is how long this unit can continue operating on this level, I will update in a few months - good or bad. I believe we made a good choice with this product. Time will tell. Do like that the remote control can control temperature versus the thermostat in the unit, that way the whole area gets cool and not just the area around the unit. Noise level is normal as it is a window unit , you do hear it running as expected nothing crazy & you can't expect it to be whisper quiet and still do it's job, it is a good size unit. ... show more

  • Affordable and lightweight
Size: 5,0000 BTU Style: Cool Only 115V Color: Clean White
Good air conditioner for bedroom. I was looking for something lightweight and this fits the bill. I have a similar size GE and it looks identical to this. Works great and we run the fan on low speed since itโ€™s a little noisy on high.

  • Just Right!
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
I needed a tiny window unit to supplement my central a/c in an upstairs bedroom. The windows were so small. I've had it about 2 years and it still works great. I haven't noticed much change in my electric bill and last summer it was on constantly upstairs. It cools great and is no louder than most window units. It doesn't weigh much so it's not stressing my window frame. My daughter slept great snuggled in a thick comforter while it was cold at nights. I was concerned because it wasn't a name brand I was familiar with,but it's been through 2 hot summers and still works great! I couldn't ask for a better price or product. It's not easy finding one so small. I would recommend this and buy it again. ... show more

  • Itโ€™s a good AC but had some issuesโ€ฆ
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
Its a good little AC unit. But a couple of issues. I have small horizontal slider windows in the basement part of my house. It was really hard to find an AC unit that would fit a 15โ€ wide window opening (with the frame still on). We were trying to keep the frame on so we wouldnโ€™t have to worry about filling in so much gap space. It is important to note that the width in the image is wrong. It is NOT 15โ€ wide. It is 16โ€ just like the depth. We ended up just having to remove the entire window frame to make it fit. But in removing the entire window frame it left a big a gap on the sides that we had to cover with wood. The packaging is not the greatest. There was a big dent on the side and the grill in the back of the unit was somewhat smashed. The little lines on the grill were all crooked where they had been smashed. When I bought this item it was non-returnable from the seller. It is loud but it does cool. I have to turn it off at night because it is so loud. On the plus side I like that it has a timer feature. It has many modes such as cool and eco. I usually use cool mode. The eco mode was really annoying because it would constantly come on and off and the noise was loud. It gets the job done but if I had known we were just going to have to remove the window frame anyways I would have bought another brand. ... show more

  • GREAT AC!
Size: 18000 BTU Style: Cool Only 230V Color: Bright White
Should've wrote a review long ago. I will make it short. This AC does all it claims to do and it is great! Blows out very cold air and has for over a year or more now! It is so worth the money and even in the extreme southern heat where I live it's GREAT!

  • Defective items sold via Amazon resale
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
I purchased an air conditioner from Amazon โ€“ sold by Amazon Resale. The item arrived defective. The item was ordered May 2nd and installed late June. The cooling does not work and the on/off button does not turn off. I had to unplug the item to turn it off and it then made a long hissing sound. This item was NOT tested and should never have been sold. I attempted to initiate a return and 2 mailing labels were created but with incorrect addresses. After calling customer service, I was assured that UPS would pick up the item only from the location it was shipped to. However they arrived at the wrong location to pick up the item. After yet again calling customer service and speaking to the supervisor of returns of bulky / heavy items, she informed me that the system would not allow her to generate another return label and that she could not help me. I lost $200 on a defective air condition sold by Amazon resale. ... show more

  • I'd buy it again
Size: 6000 BTU Style: Cool Only 115V Color: Bright White
The only thing I found weird about it was the remote control doesn't seem to work properly with the unit itself, but I probably need to read the directions more. It works great, installation wasn't bad.... And I love the fact that it has a built-in dehumidifier. I tried that on a very humid day and that actually helped a lot ... show more
