  • Good quality, heavy-duty, all parts were included and very easy to install too.
Size: 12000BTU, 115V, 20 SEER2
The media could not be loaded. My old mini-split in the garage kept leaking coolant, so I looked for a higher-quality brand. I found this one with really good specs and a nice size, and I had to give this one a try. I was not disappointed; this one has worked out great. First off, I love how easy this one was to install and with no issues too. Came with everything, the hoses, wiring, mounting brackets, and really easy-to-understand instructions too. Install was in place of another one, so the hole was already there. The hoses easily fit and connected to the outside unit easily as well. Wiring was easy, already had the outside connections, so all in all, took me just under two hours to install. Secondly, it works great. I like how it puts out the cool and is so quiet when it does it, too. It is so nice how it brings the garage to temp and keeps it at temp too. The remote control adjusts the temperature and modes and does it from a pretty good distance as well. Lastly, I really like the outside unit, which is a lot quieter than my old one, and the neighbors even mentioned it too. Also, I highly recommend testing the connections with soap water and look for bubbles. I had one fitting I did not tighten enough, and found it that way, and is a foolproof test too. No cons, it really worked out great for me, and I am very happy with the purchase. ... show more

  • Very impressed. Easy to install. Very efficient.
Size: 12000BTU, 115V, 20 SEER2
This unit works great. Quiet. Almost makes no noise. It will pay for itself in about a year. No need to cool the entire 4000 sf house with a 5 ton A/C unit when my wife and I are sitting in the kitchen nook most of the time. EZ to install. I installed mine from start to finsh in about 3 hours, not counting many trips to the hardware store. Just watch the installation video a few times. It comes with everything you need for basic installation, but I think most people would want to buy extra stuff unique to their own install. Comes pre-charged with freon. The system needs to be evacuated prior to opening the lines. Sounds complicated, but it's not. Just watch the couple minute video. It's as ez a screwing in a light blub. Orielly's auto parts rents the vacuum pump to evacuate the lines for free or just buy one on amazon for about $125. I simply plugged my unit into a regular 110volt outlet. Most video's say not to do that. This unit uses about the same electricity as a refrigerator or a space heater, or a microwave, so whats the big deal. Nothing has exploded or burnt up yet. Check the fuse rating on the outlet, mine was fine. I am planning on installing another costway mini-split in my master bedroom and maybe the garage. Highly recommended. ... show more

  • Working perfectly..... So far.
Size: 9000BTU, 208-230V, 17 SEER2
Beginning in October of 2023 I purchased eight of these units for rentals. The heat and air work perfectly. People looking for mini-splits should be encouraged. These are easy to install and work great. The price is almost a third of price I was paying locally with my contractor discount for well-known, similar size mini-splits. ... show more

  • Costway mini split
Size: 12000BTU, 115V, 20 SEER2
The product is great. It is super easy to install if you watch the video Amazon has on product listing. If you got by the directions then you will be lost. I recommend getting the wall mount for the outside unit. The unit both heat and cools great. I am super happy with it. UPDATE: 4/23/2023 The unit stopped functioning 3 days after install. I called the "customer service" number for Costway and got little to no help. The machine put up a code that they have never heard of and they wanted me to send them a video of the unit so they could trouble shoot it. While I was waiting I called all the local HVAC processionals in my city and they said they could not help me either due to the Free-on in the unit. There is little to no R-32 for sale in the states that I could find. I had a HVAC professional come out and looked at it and they said it need for Free-on and there had to to be a leak in the unit because the lines were sealed. BEWARE OF THIS UNIT. ... show more

  • Excellent AC Unit
Size: 12000BTU, 208-230V, 17 SEER2
The media could not be loaded. Loved this product and it made a world of a difference! We used this in our garage which has no insulation inside and it completed cooled down the space. The unit came in two separate boxes but it has everything you need to set it up, although my husband is very handy and good at figuring things out. It is very quiet you can barely hear that it is on. There’s also fan options which allow you to adjust the speed. We haven’t tried the heating feature yet because it is very hot out. There is a timer feature on here as well which is great. We have been turning it off at night but leaving it running for most of the day to keep the space cool. Would absolutely recommend this unit for anyone looking to cool down their space! ... show more
