So far so good
I just received my unit yesterday so I can’t say too much about it. It did arrive as scheduled, the delivery person was helpful and courteous. It was carefully packed so there was no damage. It was also very easy to unpack, I just cut the plastic straps and lifted the box off the unit. I purchased it for my 35-foot fifth-wheel RV to reduce the utility costs. I keep it parked in a resort on the Kentucky River full-time. I was surprised at how sturdy the panel that goes in the window was and after a few adjustments to make it fit the rounded RV window, it installed perfectly. It was easy to set up and get running using the controls on the unit. I have not been able to connect it to the internet yet, it won't work on 5g and we have Starlink 5g, so I'll need to work on that. Also, the control panel on the remote is in Chinese and the instructions don't tell you how to change languages. I set the unit controls on automatic and 70 degrees and it has functioned perfectly. It switches from cool, heat, and fan as needed keeping the camper at 70 degrees. I will note that the outside temperature has been fairly mild so far. It is incredibly quiet. It will need some kind of vented cover on the outside, it's kind of exposed. I had to empty the evaporator tanks a couple of times and I find the three outlets confusing and possibly unnecessary. The lower pan seems to collect all the extra water and is so close to the floor that it is impossible to empty it without lifting the unit. After flooding the dining area twice I finally attached the hose to the bottom outlet and drilled a hole to continually drain it outside regardless of what mode I am running it in. I'll update this review after I use it through some more demanding weather and after I get a utility bill.December 28, 2022 update:I have used it through some mild and extreme winter weather. It starts to struggle under 40 degrees outside but does produce some heat into the mid-thirties. At that point, I switched to my propane furnace and set the unit on “dry” to keep the humidity under control. In Kentucky, we usually have temperatures high enough to run it during the day, and only use propane at night when I keep it cool inside for sleeping. I figure the unit has saved me about $100 a month in heating costs. Propane is very expensive in the area where I live. We are two miles past the boonies.October 21, 2023 Update:Well, I've used it for over a year, and it is on almost 24/7 and has never missed a beat. We have had some very hot weather this summer, and I have set it at 72 degrees on auto and just let it run. An RV is basically a metal box sitting in the sun and it keeps it cool all summer long. It did struggle a little when the temperature was over 100, but the ceiling fan on high made it tolerable. My electric bill in 2022 for August was $144, we had higher temperatures this August (2023) and my bill was $89. By my calculations, this unit has paid for itself in one year in lower utility costs. It does make some unusual noises as it cycles through, and can be a little loud at times, but it is still much quieter than the roof unit that came with the camper. I could not be happier with this product and definitely would recommend it.

Third party purchases are risky.
I purchased 2 and less than 6 months cold weather started in NY and I went to use the heater. The heater worked two or three times then nothing. I called Amazon and they refused to honor the warrantee and directed to call Cooper & Hunter. Cooper & Hunter refused to give me a refund because I it was purchased through Amazon. Amazon also refused to give me a refund. Cooper & Hunter replaced the defective unit. Now the other units from my original purchase is not working. I've been trying to reach out to Cooper & Hunter as calling Amazon is baseless. Hopefully they'll make things right, or at best, offer an alternative. As for the replacement unit I received, the box was damaged. I still have not taken it out of the box. I would not make another purchase of this product for the reasons stated. I would have preferred my money back.

Works great! Fitting details not quite accurate though.
First off, the unit performs great cooling off my 24 x 24 insulated garage. With all of the doors closed on a 93° day, it took about an hour and a half to drop it down to 74°.When it is catching up, it’s not the quietest unit, but it does get reasonably quiet once it is at your set temperature. Everything ramps down, both compressor and fan if you have it set to Auto. I am extremely pleased with the performance since my last air conditioner was a 14K BTU as well but was a single hose and on similar 93° days, it would struggle to keep it at 80° and would run all day long.My only con for this unit was that it stated 19.5 or 20 inch window fitting width (as well as 6 inch height) but what I received was around 26 inches wide with 10 inch height. I was able to make this work easy enough just by cutting down the main bracket where the hose attaches using a jigsaw. Tablesaw or Skil saw would probably make a straighter line than my jigsaw skills were able to make though. (:Also did not receive the vertical adapter initially, however the vendor did ship that to me pretty quickly for free after I contacted them which was a promising first impression on their support.However, the problem I have with the adapter is the fact that there’s not enough room with my sliding window to be able to use it. Picture attached. Also not really sure why the adapter has such a long divider piece sticking out the end between where you connect it to the window bracket and then protrudes out towards your screen by about one and three-quarter inch.Likely the issue is because this is a garage window versus a house window, but I did not realize any of that prior to ordering so maybe this will help someone else make the decision. But again, I made it work as it is without too much of a problem. You can make pretty much anything fit if you have a Dremel, jigsaw or other tools available.Overall, extremely satisfied. Took off one star just because of window mounting inconsistencies between the description and what was received but also due to the limitations of the vertical adapter not coming with it initially and also not being deep enough likely for some window installations people will have.
