Easy install
Set name: 12000 BTU 230V/20 SEER2/Visio Series
Very nice unit. I'm very pleased with purchase. Seems to work perfectly although I just installed it. I'll see how great the heat works when it gets cold out

Excellent unit, works really well.
Set name: 12000 BTU 115V/20 SEER2/Visio Series
This air-conditioner has met and exceeded my expectations. It cools my room down very well in Southern California triple-digit heat. And the price is reasonable. I had some help with a HVAC pro for installation - positive pressure test with nitrogen (200 PSI) held for 30 minutes. Then negative pressure (-30 PSI) held also for over 30 minutes before I opened the refrigerant. It works like a charm. Their customer service was also responsive and helpful. I will definitely buy Cozeware again. Very happy with my purchase. ... show more

Make sure you own a vacuum pump, and hope you get a good AC, because support is crap
Set name: 24000 BTU 230V/20 SEER2/Visio Series
Buyer beware. Quality is crap as is customer service. As I was installing it I found you must have a refrigerant pump in order to install this, no where in the description is this mentioned. But OK I always wanted a vacuum pump so OK 3 hours and $150 later I'm the proud owner of a refrigerant vacuum pump. Get it to a negative pressure and complete the installation. Turn on the breaker it blows hot air and throws an F6. Open the guide and it states bad connection to the wiring, or a bad board. So I go through everything, check it all. everything is right. So I call, they are only open till 6 eastern I'm at 5:30 mountain, dang it. So just to make sure I go through everything again, I even tone out the connections through the back side of the terminal block, cause you know, maybe a bad crimp on the wire connectors. I've been doing this stuff for a long time I've seen it. I even check the wire leads going to their control board. So just to be detailed I record the voltages between legs, indoor and outdoor and compare them, no drops in voltage, everything is good. So I send a very detailed email to their service department with the troubleshooting done, voltage readings etc, along with a screen shot of my invoice. I get back an email from Sophia in the middle of the night that states I should check the wiring, and they can't find my order, I need to pdf it. WTH? So I leave work early so I can get to a position to troubleshoot it with them on the phone, When I get hold of them I am informed that they cannot help me as my case is being handled by someone on the nightshift. So I email them again explaining it all again with pictures this time and a PDF of my order. My reply is that this time they want video. Video of what? it lights up and shows an F6 on the display. She also wants me to take readings of connections that aren't there. So they are either asking me to tear the unit apart and test it live, or she has no idea what she is talking about. So here we are I have initiated as return, I will have to spend a whole day tearing the thing down packing it up and returning it. And wholes have been punched through the wall in my shop to accommodate this unit. 2 full days wasted and about 6 hours of troubleshooting and writing emails. Save yourself a lot of headache and buy a reputable brand. ... show more

Good product and good customer service. No Home Assistant integration.
Set name: 18000 BTU 230V/20 SEER2/Visio Series
This is for the 18k btu 230V unit. The cliff notes: Would I buy again? Yes. Would I recommend? Yes. Are there some issues? Yes (see the end of this review). The details: Bought this for our 2 car garage in Rhode Island where we don't have the brutally hot summers I'm used to in FL. That being said, this unit would probably be just fine down south as long as the garage doors are insulated as well as the outside walls. Installation went well and although the directions are a little thin they are OK. Be very careful about the order/color of the wires. I wasn't and did end up having a problem. Since this unit is 230v my hack brain said it doesn't matter whether it's white to white or white to black on the mains power. In regular old outlets you can reverse the two hots and it's fine since they are basically just a mirror of each other out of phase. The detail with the mini splits is they also have a signal wire and apparently the signal wire (which is DCv) uses the white wire as it's negative/neutral. Since I had the black in that position when I turned it on the indoor unit fan would come on for 30 seconds and then get an F6 error. The outdoor unit was getting power (I opened it up and checked the board and led #1 was coming on then after 30 seconds going to a 2-flash indication). I took photos of everything and sent it off to Cozeware and right after I sent them I was looking more closely and noticed my sloppy wiring on the L1/L2 being reversed. I wired them as the directions said I should have (we don't need no stinking directions!) and bam the unit came on and started working perfectly! It took my garage from 85 to 74 in 20-25 minutes. It wasn't a really hot day so I haven't seen it working hard but my portable 14k unit was fine until early afternoon (sorta) but it would lose ground on a hot day and never keep the temp below 80 by late in the day (my walls aren't insulated apparently although the doors are). What are the issues: I am an avid Home Assistant user and this thing has no native integration. This is really annoying to me but life goes on. You should apparently be able to use the Tuya integration but somehow that screws up the F/C temps and keeps flipping the unit to C when I want F. TuyaLocal just won't add it at all. My solution? I'm going to use a Cielo Breeze Max I have from our rv (no longer being used) to manage this thing and move on with my life. Cozeware: PLEASE fix it so that home automation systems like Home Assistant can talk to this thing. Just having that on your website will bring you new customers (maybe not a lot but definitely NOT having it will cost you customers). So, overall I'm happy with the unit. The customer service interaction was good. Don't bother going through the Amazon support to talk to them. 12-24 hour delay between messages/replies.. Just go to the Cozeware website where you can open a ticket and they'll generally get back to you in an hour or so in my experience. If they'd fix the Home Assistant thing I'd happily give it 5 stars. Time will tell how reliable it is. ... show more

Geat purchase. Would buy again.
Set name: 12000 BTU 115V/20 SEER2/Visio Series
Excellent product. A couple things. You'll need to either know how to run your own electrical and have a vacuum pump and the 5/16 gauge adapter as standard Refrigeration gauges dont fit (you can buy it on Amazon), it have a professional install. Once I installed it worked great immediately in cooking mode. I can also verify that hearing works well too. I accidentally had it set on 84 degrees and on auto. I walked into the garage feeling heat blowing out as the garage was 78 degrees. Make sure you pay attention to that. The app works great also. Great buy worth the money. ... show more

Excellent system
Set name: 12000 BTU 115V/20 SEER2/Enduring Series
These are so great I bought two! Easy install if you have the required vacuum to vac the line set. Don't be fooled, you DO have to vac the line set as it is not charged like the condenser is. Once installed it is fantastic at keeping any space comfortable. I also bought the line set covers separately because I wanted it to look tidy. ... show more

READ about the 16' of piping and beware! Works perfectly
Set name: 18000 BTU 230V/20 SEER2/Visio Series
Hard tine rating this. Let me tell you why. The piping to the outdoor unit was only 16 feet long! No place in the listing did I see that! I had to buy an extension kit that was almost as much money as the system. On the plus side, it functions perfectly and was easy to install if you have the proper tools. It's so efficient my electricity went down! ... show more
