  • Low watt usage and cools great
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
Perfect for solar since full blast on 68° it uses 420 watts and fan only 80.

  • They are good.
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
Product worked well right out of the box, it was a very easy installation following the instructions included, no other material needed. Would buy another of this brand if another of my old units breaks down.

  • So far so good
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
A little more expensive than similar models, but this was the smallest one I could find, and was necessary for the opening it had to fit. It's listed dimensions were correct for the unit, but didn't take into account mount accessories. I still got it to fit with some effort. Like all new units, this took about 15 minutes to really get cold. It has since stayed very cold, and runs pretty quiet. It actually puts out a lot of cold air and should chill an area much larger than it's intended for. ... show more

  • It’s a good AC but had some issues…
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 15” wide window opening (with the frame still on). We were trying to keep the frame on so we wouldn’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 15” wide. It is 16” 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

  • Fits in a small window.
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
The bedroom windows are quite small (narrow). By leaving one of the side expander/fillers off I was able to just get it to fit in the window. It ran all of last night just fine. Fingers crossed. I've had some problems with refrigerant devices in the near past.

  • Great value for your money!
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
So far so good. Gave into this NY heatwave and purchased this air conditioner. Size was perfect for my small window. Love the digital screen and convenience of a remote control. Noise level isn’t too bad; some may think it’s too noisy but I live on a high traffic street so the air conditioner hum doesn't bother me. Cools the room quickly. Can’t speak on the energy efficiency. I was skeptical at first but it’s a great unit for the price. ... show more

  • Defective items sold via Amazon resale
Size: 5000 BTU Style: Cool Only 115V Color: Bright White
I purchased an air conditioner from Amazon – 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
