  • COSTWAY 18,000 BTU Mini Split Air Conditioner,
Style: 18000BTU, 208-230V, 21 SEER2
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. ... show more

  • Awesome unit.
Style: 23000BTU, 208-230V, 21 SEER2
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. ... show more

  • Affordable HEATING AND COOLING!
Style: 12000BTU, 208-230V, 21 SEER2
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 We chose mini splits because the house we bought had outdated baseboard heating and no central AC.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! ... show more

  • Absolutely worth every penny. Don't get fooled by being one of the "cheapest" units.
Style: 12000BTU, 115V, 22 SEER2
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. ... show more

  • Short lived
Style: 23000BTU, 208-230V, 21 SEER2
This unit was fairly easy to install, though you will need a vacuum pump to install it. It heats and cools very effectively. I have two big complaints about it though. Firstly it is extremely inaccurate about what the room temperature is. It will be set to cool to 70 but it will not decide it is 70 until a thermometer on the other side of the room is reading about 63. This is extremely annoying because you have to babysit it or else the room will be about 10 degrees warmer or colder than you want it. Second off the app to control this thing is absolutely garbage. It refused to let me create an account I had to have someone else set it up. It is also such a no name app that the only function it surfaces through Google Home is turning the unit on and off. No temp or mode controls totally worthless. It also does not support Home Assistant with a lot of bridges and hackery to make it work. Overall consider finding a better unit. *UPDATE* a few months later the unit is now constantly throwing the P5 code which seems to be related to over temp protection when heating. Checking the indoor unit with a IR thermometer shows the fins are only about 75f so definitely not over heating. Definitely spend your money elsewhere. ... show more

Style: 18000BTU, 208-230V, 21 SEER2
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!!! ... show more

  • Best mini splits I've installed so far at 1/3 the price.
Style: 12000BTU, 115V, 22 SEER2
Amazing units! I purchased two of these 12000BTU 22SEER units in August. They performed very well at !00*F and are performing great today at -3*F. I cant believe this is producing heat at this temperature and using only about 1000W to do it. The electric radiant heater this replaced uses 1500W and couldn't keep up. This mini split has no problems at sub zero temperatures. I've had other brands of mini splits that were triple the price and didn't perform nearly as well. ... show more

  • It works very Well! Efficient quit unit. Have had it for 3 weeks now with no issues.
Style: 23000BTU, 208-230V, 21 SEER2
The ac is ice cold and the heater is hot! It works quickly and it is quiet. The puddy is under the condenser as well as the flange for the hole. You might need more insulation tape and other items for installation that are not included. The wifi is not user friendly. I was not able to set it up yet. It blows super cold and super hot. It is not a loud condenser. It was heavy but not impossible. If you are not handy do not install this yourself. The instructions are very general and not specific to the unit in the box. Price was great for the performance. It looks sleek! ... show more
