Set name: 12000BTU, 115V, 20 SEER
After I finished installing and running it, I must say that I'm very satisfied with the purchase and the quality and results achieved from this item. Using only 120 volts the system runs nearly silently, while the amount of air discharged by the vent is very significant. It took watching a few different videos to fully comprehend the task at hand, but I took my time and went step by step, making one significant exception that I thought could be helpful in colder months, so I routed the condensate drain line on the inside of our garage, and at the bottom I coupled it with some CPVC parts and ran it through the exterior wall so the drain is outside. I did this because in my experience, drain lines can freeze up solid in very cold temps, and shut down a system.....it's happened to me more than once. This way the drain is only really exposed just a few inches outside the fully insulated exterior wall, and should be able to resist freezing.......we'll see how that works out. I used a solid stainless steel support bracket which was tricky to install, since the side to side dimension is inflexible and related to the width between the legs of the outside unit with a very small margin of error allowed. It worked out fine and I was able to give it 10 inches of air space in the back to the wall, enough for proper efficiency of the unit, and also to provide a hidden "alcove" for the coil of lineset that I left intact as it came from the factory. It looks fine, especially since I ordered a "cover kit" for the exterior line set for a neater appearance. I also ordered a sleeve through the wall which I cut to length and caulked in place prior to passing the line set and communication wire through. (As I mentioned, I did not include the drain hose in that bundle) The most apprehensive part was the installation of a new 20 amp circuit at the panel box, which was quite easy after I digested the videos online that clearly depict a safe method of doing that. Using 12-2 copper wire, I fed the circuit partly through the wall, then out and down the inner wall surface before exiting outside to a non-fused quick-connect box that I picked up at Home Depot. The final challenge was to acquire a vacuum pump and manifold gauge set for just over $100.00 to fully evacuate the low pressure side to vent any moisture or unwanted gases, prior to firing up the system. It allowed for a one hour leak-check after shutting the valve at the manifold and turning off the pump after it was given 25 minutes to do it's thing. I feel that I learned quite a bit about some tools and techniques that I was unfamiliar with, but was willing to digest and understand through careful selection of "how-to" videos readily available online. Installed yesterday, it runs great and I love the way it silently moves the air flow up and down as well as from side to side with motorized vanes in the blower compartment. Finally, I can work in my fully insulated garage in comfort year round. I hope the heating is adequate, but in the last year, I found a single small space heater was sufficient to raise the temperature in my garage by enough degrees to make it warm enough to work in comfortably, so if the Split unit isn't very good at heating, as I suspect it will be, I can easily supplement the warming by a simple space heater to easily make it comfortable in winter. I would add that build quality was very good, and was surprised by the amount of pressure released from the smaller high pressure copper line tube when I readied it for connecting with the longer line set to take the line down the exterior to the condenser unit. That indicated that the interior unit's plumbing was air tight from manufacture to my installation, which shows the build quality of that piece. Similarly, the charged condenser was also airtight and with simply using hand wrenching without torque-indicator tools, the system proved easy to connect and insure proper leak free system. I would say that the only possible addition to the system that I would recommend would be to have a simple "on-board" control pad at the inside unit as a failsafe if the remote failed to work properly. But the remote works perfectly so far, so maybe that would just be a waste of resources and just raise the price. For clarity, my unit offered 12,000 BTU's and runs on a 120 Volt 20 Amp circuit. I spent about 595.00 on the Split A/C unit (incl. shipping), and 36.00 on the triangular stainless support bracket, 33.00 on the line cover kit, 23.00 on the thru wall sleeve kit, 10.00 on a 2.5" hole saw, 54.00 for the manifold gauge set, 55.00 on the vacuum pump, for a total of 806.00 (not incl sales tax)......I wasn't thrilled that shipping for the Costway unit was 99.00, but I guess it's a fairly large and somewhat heavy item to ship. (came in two pieces over 2 days apart) So, that's the story, and I'm 'stickin' to it', as they say.

This thing is awesome. Unbelievably quiet, I had to walk right up to it to verify it was running. I got it installed in the spring and we had some chilly days yet. The heating function worked great. This will take a nice load off my propane usage. Better yet, we're rolling through our second big heatwave. This unit cools the cabin down quickly and keeps it cool. It has also been very humid and this has pulled the humidity out of the cabin no problem. Cool and dry, it's perfect. Installation is not hard but the manual isn't real clear in some areas. I'd watch some YouTube videos or find someone who has done a mini split before to make sure you get it done right. It wasn't hard though. 5 stars easily.

I bought the 18,000 BTU (220V) mini split for my shop. The shop is 1,000 square feet, has insulated walls, but no drywall or insulation on the ceiling. It is open to the attic, so I don’t have the most efficient insulation in the shop. That being said, this unit works very well and keeps my shop comfortable on even the hottest days. It routinely gets into the high 90’s where I live and this little unit seems to be up to the task of cooling my shop. It is so quiet that I can’t hear it running from the other side of the shop. It’s quiet, but it also puts out a lot of air flow. The build quality is better than expected and so is the performance. I was able to DIY this project having very little experience with home HVAC systems. First was the electrical. I located the units as close as I could to the breaker panel in my shop so I didn’t have to run a lot of wires. I used 14/3 romex and installed a disconnect box outside that feeds power to the outside unit. Here is the disconnect box I used. It was about $25- https://www.amazon.com/dp/B000H5YAD6?ref=ppx_yo2ov_dt_b_fed_asin_title Mounting the inside unit is easy with the included cardboard template for marking the holes/drilling. The bracket for hanging the inside unit is included, but you do not get a bracket for the outside unit so if you want to hang it on a wall you will need to buy a bracket or make one yourself. I used this bracket that cost about $35- https://www.amazon.com/dp/B07B77C8T6?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 You will need a holesaw to make a pass-through in the wall for the refrigerant and between unit electrical wires, as well as the drain. I did my drain separately for a number of reasons that aren’t important here. Once both units are mounted you have to run the wiring and the refrigerant pipes between the two units. Be careful when bending the larger copper refrigerant line because it will kink fairly easily when you are not being careful. I ended up removing the insulation and using a bender that would normally be used for bending steel electrical conduit. I already had that and you might not need it if you are patient and work slow. Bends in the larger copper tubing need about at least 6’-7” radius to avoid kinking. Once you are happy with the large line, the smaller line will easily conform to the same shape because it is less prone to kinking on bends of the same radius. Probably the most intimidating aspect of the install was the need to evacuate the air from the system after completing all of the plumbing. I thought I could rent a vacuum pump and gauge set from Autozone, but I wasn’t able to make that work because the fittings are incorrect. Not finding anything that would work for rent locally, I just bought a vacuum pump and gauges from Amazon for about $120 - https://www.amazon.com/dp/B079JJSFQW?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 With the correct vacuum pump and gauges, I was able to easily apply a vacuum for 15 minutes until it was completely evacuated. Then I buttoned everything up, flipped on the breaker and hit the power button on the included remote control. The unit hummed to life and started blowing cold air in seconds. I did have a small issue with one of the plastic components that was included in the system. I called the support telephone number on a Sunday afternoon and was able to speak to someone right away. Even being hard of hearing, I had no trouble understanding the nice lady with a faint accent. She asked for my order number and told me they would be in touch within 24 hours. Later that day I got an email from them asking me for a photo of the problem. I sent the picture and then the next day they emailed me again saying that the part is on the way to my address and it should be there in 12-15 days. The part actually arrived in 6 days and everything is fixed and operating smoothly. I don’t give out 5 star reviews unless I feel the company really deserves 5 stars. In this case, the customer service after the sale was so good, they earned more than 5 stars. Great company, and they stand behind their products.

So far (It's only been running a couple days) this thing is awesome! I bought the 12k btu 115v unit for my garage, which is concrete block, and uninsulated. I work on projects some summers and I die in the heat. I use a torpedo heater in winter, but I'm excited to try this for heat, but with no ceiling and open rafters, I may not get much, but that okay too. Install was a breeze with the right amount of videos (I over prepared) watched. I borrowed a vacuum pump from Autozone and used my own old R134a manifold set to vacuum it out, and it held the vacuum for one hour. I did purchase more UV resistant tape (I have the extra copper tubing coiled up horizontally under the unit which is mounted on a wall bracket), the tubing hider kit for the wall, a 3" carbide hole saw, and a 7/8" carbide bit for the electric run through the concrete wall. Install time and it was hot outside, really hot. But I worked slow and all my by myself. Drilled the holes, ran the electric. I did have someone help me mount the unit indoors as the line set is long and needed someone outside to guide it while I hung the unit indoors. The hardest part was probably coiling the extra line under the unit so I didn't cause an oil pool in the lines. Well it was 87* and about 50% humidity the day I turned it on. All the thermometers in my garage read 90 or greater. Within an hour it was 74* and dry and my garage, and it maintains that even if I briefly open the garage door (my only ingress/egress). Now projects out in the garage only require a tiny bit of planning to turn the unit on, and go out about an hour later. I usually use the timer function so I don't forget to turn it off. Yes, you will need some tools you may not have, yes, there are good videos to show you how to do it, but take your time, and it's a relatively easy install for any DIY person. Good luck!

Updated review after a week of observation: The flare joint threw out the copper pipe while its still very tight for a very small movement of the line! All refrigerant blew up! This is a manufacturing defect or design issue. The flare joint is supposed to hold the mechanical small movement stress and allow if required bending of copper pipe but not just blowing out copper pipe line out! I am returning it. Good review after installation: I think its value for money. The most affordable system! One thing I did not observe is this model is 53 DB for noise, I did test after installing with noise meter, it was 45 dB, lower than the product documentation! However I noticed that the new 115V mini split from Costway is 23dB! I got confused and thought all are 23 dB, else I would have ordered 115V mini split only. This model seems old launched in 2017 or 2018, thats why noise level is 45 dB against product documentation of 53 dB. Documentation to install is good, just higher font for labels will make it more readable. Costway also had youtube official video to install which helped, however vacumming was trickly and steps are not clear. Before connecting the lines to outdoor unit, one should ensure the vaccum pump is really sucking from lines. To make sure first connect vaccum pump to to service line before connecting other side of line from indoor unit. Turn on vaccum pump, put your finger other side and ensure its sucking. Now connect the lines and flare properly. The heating side: After installing I tested cooling, it was faster, however when I tested heating, it took few minutes to start heat pump. Not sure if it is normal. I will observe for few more weeks and write more reviews. Overall the product seems to be promising with great price and more value for money. Considering the low price I would rate it 4 to 5.

Installed for the last 3 months. 12,000BTU 120v version. Has tons of heating capacity down to 37 degrees and then still heats down to 3 degrees F in Ohio able to keep two rooms at 70 degrees in a 100 year old house right now at night. That’s the max it can do in this extreme cold. But that’s plenty. Whisper quiet. Great value. The install matters the most. Must vacuum down the lines. Tons of heating capacity down capacity above 37 but diminishes under that yet still does heat. Cooling power is great. You can’t set it any lower than 60 degrees if you want to use it for keeping things from barely freezing. Good overall build and design. Can’t really beat it for the price. Pre charged. Buy $200 in tools and watch YouTube videos and do it yourself. No it’s not as good as a Mitsubishi hyper heat but it’s also 75% cheaper. Nothing arrived damaged or missing. The manual is worthless for installing. It’s generic. Use YouTube. Not good for those who want precise temp control. This fluctuates between 3 degrees of the set point. I didn’t get the WiFi version. This doesn’t really ramp up or down in small intervals. 100%. It works in steps like off or 25%-60%-100% and you cannot dictate what logic it uses for output. You can only set the fan speed. Mode. And temp. It decides the rest. For this price you simply can’t beat it. Even if it dies in a few years. Still a deal. Update: 9 months in I had a support issue and Costway mailed me a part ASAP and sent an instruction video quickly. 10/10 customer service. Ended up being my a small mistake on MY install and not their product at all! Fixed and away we went! Mini split has been cranking away at 100% all summer in 100 degree heat flawlessly with no break.

It's a great unit. I was extremely surprised by how silent it runs. Remote is quick to adjust temperature and nice they include batteries for remote. I had plenty of lineset and wire for my area I wanted it. This is installed in my enclosed trailer shop build running off a pure sine wave inverter and lithium batteries. Luckily I have a friend with all the hvac tools so install was a breeze. We had to cut the lineset by about 2-3.5 feet and reflare the ends to make it fit the way we wanted which was easy. Vaccum and nitrogen test went great. We had a small nitrogen leak but realized we over tightened the ends. Loosened them up and all good. We had to go through some metal plate and that cut up the insulation so I had to buy some more and reinsulate but that was easy. The fan clicks off for a while periodically when temp is reached but the inside unit is still pumping cool air. It made my shop a wonderful place to be even in 85 degree outside weather. The only reason I knocked off a star is the remote information is lacking. I still don't understand what the auto mode does. You can't set a temp in auto and can't use the temperature sensor on the remote in that mode. So I have just left it in cool but then you cant adjust fan speed in that mode which is odd. I may have to call company and ask because it makes no sense. But it does cool and I turned it on heat one night and I was sweating profusely after a few minutes. So that works well! I wish I would've bought a wifi unit but this does work very well. Well worth the price!

I am a licensed hvac contractor in NC, this unit is excellent, pulled a 1 hour vacuum an over kill, opened ports and it has been running for 3 months cooling my 16x16 shop warehouse. I would compare this to a much higher end unit like Mitsubishi in performance. I do not know the long term of it, but I can say out of the box installed perfect, runs very little time keeping my unit cool. 73 degrees f at 100 degrees outside, that’s a 27 degree drop in temperature, awesome. I did heat los heat gain calculations and 9000 Btus was right size. This unit is out performing my expectations of a 20 degree drop in temperatures. Excellent unit!
