I bought this to add to the bedroom. The instructions were very thorough with lots of installation hints which was nice since I had never installed one by myself before. A few minor issues such as the wall layout for my model was wrong so I had to figure out where to drill the hole myself. The through the wall hole size that was shown was also a good 3/4″ too big, but that helped when installing it later since it did not quite line up right. All the components seem high quality and durable, made in china of course. Be sure to use the special refrigerant lubricant/sealer, RT201B Nylog Gasket/Thread Sealant available on Amazon, on the flange connections when installing the copper tubing, it really does help prevent leaks which are the biggest issue with these units. That is not mentioned in the instructions BTW. Once installed, the unit is super quiet both inside and outside, works fast and seems efficient. The heat function is great, can’t wait to try it this winter. Be aware that unless an HVAC contractor installs it, there is no warranty. You will need some special tools such as a calibrated digital torque wrench to the tighten the connections properly, a vacuum pump to clear the lines and possibly some copper pipe flange tools if you need to change the length. Overall it is a somewhat challenging do-it-yourself project unless you have some hvac experience and tools handy. I would recommend buy the plastic covers for the lines as shown in the picture, gives a cleaner and more secure finish. Of course the next one would be easy………

We added this device to our basement and it was a great purchase. Easy installation with the help of an electrician who helped get a power source on the outside for us and a licensed HVAC to install the unit. Runs great and quiet and the wireless feature works well so far. The basement is cool and comfortable.

The temperature is exact we use this in our dining room and laundry room which did not have regular hvac system placed. The performance is 100% if you have a trailer you could totally use this and not pay as much for a regular hvac system. Ease of use is simple as it comes with a remote. There was no damage when it arrived, this product gives value for money!

This is a quality item. Only one complaint — the Wi-Fi dongle is missing. I have emailed Cooper Hunter customer service about three days ago and have not heard back, so I will call. At this point it is too late to send it back for just on missing part. Of course, without the Wi-Fi USB flash it is usless for remote control over your cell phone.
Be aware, also, if you install yourself, that you will need a vacuum pump to finish installation. It comes recharged but the cooper lines running to the inside and outside units do not. You need a $150 AC vacuum pump to finish install. Plus you will need an additional brass, reducer fitting to attach, unless the pump you order comes with the proper fit — if not, that will be another $10. I am waiting for a pump to be delivered — I ordered one but was sent a Truck Milti Hitch. I had to return this wrong item and reorder a pump. Also, be aware, Cooper and Hunter have covered themselves with multiple warning about self-installing, saying they only authorize trained, licensed techs for installation — just so you know. But many have said that their customer service is great, all the same. We will see. If I have to buy a replacement USB dongle? That will be another $60. So far the install has been pretty straight forward, and having install one of these about 4 years ago, I am familiar with the installation process — just so you know. If you have tool skills you should be able to do it.
30 days later and this mini split is working perfectly. Nothing bad to report. A very quiet unit. Loving it, in these hot, triple digit temps we are getting as we move into summer. Perfect timing.

I purchased this .75 ton single zone system for my master bedroom which is always hotter than the rest of the house. So, this is providing supplemental cooling to a room. I was lucky to have an ideal situation of having space on an exterior wall in the room so the heat pump could be placed just on the other side, with an electrical subpanel within 10′ of the unit. So, very straight forward install. I purchased a 2 3/4″ hole saw to make a clean hole on my interior drywall, then used a small masonry bit to make a series of small holes in a circle on the outer stucco wall, being careful to create a slight downhill slope from inside to outside.
Some comments about the instructions that come with the unit:
– the description of wiring connections refers to colors that didn’t exist with the kit that I purchased. In the end, colors don’t matter a bit, just make sure the order is identical for connections 1,2,3 and ground on both sides of the control cable.
– the manual mentions in bold letters to be sure to plug the drain in the drain tray using the supplied plug on the side opposite of where the drain hose is coming out, since it is designed to support either left or right side drains. I couldn’t find any plug, so I called support. They said ignore, it’s already installed at the factory, and since I didn’t need to change it to the other side I was fine.
– the manual mentions to test your drain by removing the filter screens and pouring water into the tray. This is not obvious where to pour the water. Tech support said to pour over the evap coils. My first try I poured a little too far back and water ran down my wall. Then I poured a little close to the front and water ran out the drain line like it should, with no leaks.
– the very good news is that tech support is available. I probably waited about 5 mins on hold to talk to a tech, and they were very helpful.
Once the physical installation of the indoor and outdoor units was complete and the circuit was run, I called my HVAC friend to come over and complete the install. He insisted that we cut the stock flares off the lines and reflare the ends, as the factory ends are usually flared with too much pressure resulting in very thin flares. Sure enough, his flares were much thicker than the ones he cut off. Also, we found a piece of loose copper in one of the 5/8″ flare nuts which would have caused leaks for sure. He then made the connections and used nitrogen to test the lines to 700psi for 10 mins, then pulled a vacuum for 10 mins. Finally when he was satisfied that all air was purged from the lines he open the valves to charge the system, and it works perfectly. I had pondered doing that part of the job myself by buying a vacuum pump and gauges on Amazon but I think I’m glad that I ended up paying a pro to do it instead. There are some hazards that only someone with a lot of experience would know to look out for.
As some other have mentioned these units are unbeleivably quiet. If it weren’t for the fact that I can see the fan moving on the heat pump, I wouldn’t know it was running at all. It is really that quiet.
Hopefully this will provide many many years of comfort!
