Bought this in August of 2024. Have used it steadily for 1.5 years now. Cools and heats a 900sqft open shop. It does a good job. I have not had any issues with it what-so ever. Installation was not too hard. The Install direction are just okay - but I managed. My unit is 208-240V. For the cost - it was really a bargain. I would recommend to anyone that is a DIY type person. Having a HVAC tech install it would have really upped the affordability. So far - it has been a good unit. My thanks to the supplier/vendor for the reasonable price and quick shipping.

Works flawlessly, rapidly cools 20'X40' w/12' ceiling bedroom and maintains temp with no problem. I seldom run it below 73F but tested down to 69F. Texas hasn't gotten over a 100F yet this year, but not expecting it to struggle to maintain temp. Well packaged, well reinforced internally to prevent damage -- zero shipping damage -- this is extremely important. Purchased another brand (starts and ends with T) that was very poorly packaged/fell apart and missing parts, worried if it was going to work. Can't hear outside unit when in use, indoor unit could be a little quieter but still very quiet (I'm looking for absolute silence when sleeping). Came with everything you need to install. This is an unsolicited review -- I absolutely hate Vine reviews.

Bought the 12,000 btu in January for a renovated 460 sq ft garage apartment. It’s May and still going. Be sure and clean the filter frequently. Super quiet. Works like a champ! My a/c guy originally said to get Mr. Cool, but has changed his tune. Now prefers these a lot. Charged us $400 to put it in. We already had the electrical in place because my son’s an electrician. Very affordable home improvement. Simple to operate. We bought two more, one for the 385 sq ft master bedroom, same BTU’s cause it’s the west side of an older home, and a 9,000 BTU for our 160 sq foot music shed. That one arrived without a filter cover. Called Costway customer service. Kathy was friendly even while sick. They sent cover. Took about 10 days. Finally got to turn on the shed’s mini split. Then after a week it wasn’t cooling. A/C guy came and charged the line. May have a leak in the line set. Not sure yet. Should know before too long. They didn’t find one. He said Costway would send another unit if it stops cooling again. It might be in the blower area the a/c man said. Even with the inconvenience, it’s been relatively painless overall considering the cost of the mini splits. Highly recommend.

It has performed great for a couple of months. I was concern that the noise from the outside unit would be high because we set it right outside on our bedroom . To my surprise, the outside unit is almost silent. We've had multiple 100+ degree weather almost all month and the unit has preformed great! we keep it at 74. Anything lower makes the room too cold, yep is that good. The only downside, is the remote. The instructions are not very clear specially when trying to set the timer. That is is the only down side. But other than that, we are very happy with the purchase so far. Installation was standard, meaning nothing different from every other unit, brand or size. For the installation you will multiple additional tools. but again, this goes for every other unit regardless of the brand etc. The air flow form the inside unit is great. The noise is similar to an standard fan. Overall, very happy with the quality of the unit.

-100 stars. ordered a 2 head unit thru costway, 3 ton system. FIRST unit kept freezing up and showing fault codes. after multiple emails with "tech support" (which takes minimum of 24 hours to get a response of which the response is very vague and gives little to no actual technical information for me to trouble shoot) they decided it was a sensor issue. Sent me new sensors, same issue. Fault codes and no working unit. Then they offered to send me a replacement unit. (after implying the original unit was not installed properly, I've been in HVAC for 42 years, it was 100% installed properly) The new unit arrived with damage so I swapped the parts out with the old unit. New unit ran for approximately 2 weeks until the outdoor temps dropped below freezing. The bottom 4-6" of the condenser does not defrost during the defrost cycle. The ice continues to build on the condenser unit it stops making heat. " tech support" informs me that this is normal operation and I should manually defrost the unit. manual defrost does not defrost the bottom 4-6" of the condenser any more than the normal defrost mode. After sharing the below pics with "tech support", they told me they were going to have a team come to the job location. However, when I asked a time frame for their arrival and if they wanted the unit completely defrosted before they got here, they informed me that the team had to return to their country and offered me $300 as a commercial gesture and told me to keep the unit! I replied that this was far from satisfactory and I wanted a complete refund as well as the $300. I received a reply that they forwarded my request to the proper team and to wait 2 business day for a reply. It has been 7 days with no response, and I've sent a second email request with no response after 2 days.

I bought the 18k 21 seer unit. It works great, nice and quiet, easy to install. I would give it five stars. However the remote t-stat is not accurate, I have to set it at 84 degrees do it to maintain 76 in the space I'm cooling. no instructions on how to use the remote. Also the circulating fan on the inside unit doesn’t cycle off. I’m using this unit to cool my garage while I’m out there, so no big deal. However!!!

We’ve had these in for about two months. We chose mini splits because the house we bought had outdated baseboard heating and no central AC. Our house is 1200 sq feet and we purchased two of these. (One for the end of the hallway and one for the main living area. They are AWESOME. SO affordable for us as first time homebuyers. The installation wasn’t hard once you get the hang of it. My husband did these with some help. You do have to know your way around wiring and using a hvac vacuum. We are in the North and it’s gotten into the 20’s so far and they’ve done great. The remote doesn’t do much beyond change the temperature it seems. However I should mess with it some more. I’ve barely seen a difference in my electric bill!!!! Which is amazing. Since we have one at the end of the hallway to keep all the rooms warm/cold, I do tend to run a box fan just to keep the air flowing better down the hall. You can’t hear the indoor unit running. We are really happy to have found these. These DO come with “whips” to connect to the disconnect box outside and they do seem decent quality. We already had our own so used those. The drain hose seems flimsy so you may want to use your own pvc pipe. Thanks for reading!

The install and set up was a breeze due to the detailed instructions and it has a video walk through instructions as well. I love the unit and it performed perfectly until the schraeder valve, used for pulling a vacuum, failed leaking the R32 refrigerant Freon out slowly causing the unit to quit heating or cooling due to low refrigerant. I’m in contact with cost way now trying to resolve the issue. I do not blame the manufacturer because it is a small valve that is common failure point on all units not just theirs.
