COSTWAY 12000 BTU Wifi Enabled Mini Split Air Conditioner & Heater, 22 SEER2 208-230V Inverter AC Unit Cools up to 750 Sq. Ft, Energy Efficient, Heat Pump (Black, 12000BTU, 208-230V, 22 SEER2-WIFI)

The media could not be loaded. I needed a product that was easy to install and powerful enough for my garage. This mini split is better than I had hoped for. Installation may require a professional but was relatively easy for a do it yourselfers. I purchased the optional bracket from costway and it is also easy to install. I also purchased a non fuse disconnect, 220 line and a hvac evacuation vacuum. The install went smooth and the system works flawlessly. The unit has heat, AC, dry and auto modes. I turned the unit on AC and it is very quiet. You car barely tell it is running. Quiet but very powerful. My garage was finally cool for the summer and I look forward to being able to be comfortable regardless of the season. This is a great value for the money. I used the hvac vacuum to test the system for leaks and it was a perfect seal on my first attempt. Be sure to consult a professional if you do not have a basic knowledge of installation.

There are a good many mini split “how to” videos available on line; some better than others. I recommend looking at as many as possible because none encompass all of the possibilities (good or bad). When you watch those videos you will see the packaging, the carton inventories, and then steps of procedure. So far there is little to take issue with but in the procedures video you will see the connection of the line set near the evaporator which is the first line set couplings. Post coupling you will be instructed to UV Tape the coupled line set and move toward the coupling of the line set from the evaporator to the compressor.DON'T DO THAT.After connecting the line set to the evaporator, UV Tape the line set from the evaporator to about 8” from the line set to evaporator connection ( or whatever space you think you will need to work on those connections). If this is taped all the way to the compressor before the connection at the compressor is established and the line set is vacuumed you will have to cut your way into it to check those couplings in the event there is an indication of for a leak. Since it is a UV Tape spiral any cut and forced opening to allow room for re-torquing those connections will be sloppy and probably lack having the integrity of the rest of the wrapped line set. I suggest wrapping the line set about 8” below the coupling and wrap to the end of the line set.I have to express a measure of disappointment regarding the manufacturer’s DYI marketing approach as contradicted in operating manual notations as necessarily being installed by a trained professional; can’t have it both ways COST WAY.The change of disposition is because there are at least four catastrophic results that are very possible: you could blow your head off, you could be electrocuted, you could suffer frost bite, you could be blinded, and you could be fined thousands of dollars. A meager mention of the need for an R-32 Vacuum Pump is lacking and in need of a fuller explanation. An R-32 Vacuum Pump is designed to prevent sparks near the refrigerant. Adapters are not the answer to be able to use a vacuum pump that is not R-32 compliant.When I vacuumed my line set I had a leak. At this point I have a real problem because I know the evaporator line set is reliable but I can't be sure about the line set couplings I made. How do I determine where the leak is if all I have to work with is a vacuum pump? I can't see a leak. Maybe if my hearing was better I could hear the leak but sadly, my hearing is failing. Should I roll the dice and tighten all connections and risk opening the refrigerant valves? If I do but didn't tighten the connections enough I now have refrigerant leaking into the atmosphere. Now, I will need to call an HVAC technician and that means I have lost the DIY cost savings.At this juncture I elected to purchase an adjustable torque wrench and a nitrogen cylinder and gauge set. Nitrogen under 150 lbs of pressure makes a leak audible and I did not want to risk releasing the refrigerant without being absolutely certain the gas would be contained. The leak turned out to be the connection of the compressor. I made the correction and opened the valves for the flow of the refrigerant. Saving THE FYI advantage is important but more importantly is please of mind; knowing there is no leaks.The unit is nicely made, light, and unbelievably quiet. Once the power was turned on it performed as designed with one exception; WiFi readiness. More on that later. I installed the remote controller/thermostat batteries and read the controller instructions to find illustrations that didn't look like my controller. Confusion is never helpful when attempting to do something that is new. I am already uncertain of how to proceed and I have illustrations that don't seem to be for my application. Looking for a way to a happy ending, I encountered more confusion regarding QR Codes. The QR Codes are smaller than a US Postage Stamp and they are arranged in a block of 12 or more and I have to find the one that I need. I’m 78. My eyesight is failing! Is Cost Way only interested in the youth market? No one seems to care if the directions published are readable for ALL markets. The “right” QR contained the same information as I had already read in the manual. I set the temperature and the space immediately cooled to the point it was uncomfortable. The unit is faster and blows colder than the house system so I had to reduce it to find my comfort zone. It works well and I am happy with the evaporator and condenser.The WiFi instructions are wanting. Connecting has been very challenging. Remaining connected is even more of a challenge. I don't understand why a well written, photo guided, and proofread instruction sheet is so difficult to accomplish. I am struggling with several Chinese manufacturers because of this issue. It isn't helpful to try to make one set of directions fit many different production models if disregards, and exceptions cloud the directions. In my career I have not found experienced English proficient technical writers to be expensive. Adding the cost of competent translators and/or technical writers to the cost of the product will amount to a fraction of the lowest measure of exchange. If I have to struggle to scan at codes smaller than a stamp at least make sure it produces information that is useful. I have connected once for about 80 seconds. I am “off line” at present.CORRECTION: I am on line and WiFi is working.I like the product and I would purchase it again.

I recently move into a new apartment and the place didn’t have any ac. So like any others I looked online and found this, it was great cooling and works really well. It doesn’t have any leaking and works fast too, for its price it was honestly the best you can get. Not to mention that it’s not loud and the remote is easy to use. Also super easy to set up and get working.

I bought 2 of these, one 18k btu and one 24k, both had missing items.The 18k was missing all of the hole trim and putty.The 24k model was missing the hole trim piece and had a dent in the top of the outdoor unit. Neither comes with a template for the indoor install wich makes the install more lengthy and tedious.Build quality seems good but only have a few weeks time on the 18k unit. Seems to heat good been to cold to accurately test cooling but seems to work, cold air is coming out at about 45 degrees.

The media could not be loaded. I've installed this AC yesterday for my grandfather bedroom and it looks and works great. The installation took me a few hours, which wasn't too bad and all necessary parts were included. The only issue I encountered was with the connector for the main tube to the indoor unit, you need to be very careful when rolling it (I almost scratched the tube). The brackets are good quality and weren't too difficult to install on the wall. The outdoor unit comes with a cover for the connections, but I wrapped them with my own stuff for extra protection and would recommend to do it same. Overall, I think its pretty good deal for the price.

Great system, HVAC contractor, in bham al, I will be installing this brand in the future

Very cold, the pipes were not long enough for the insulation. But overall it is a very cold air conditioner.

Once installed it was fairly easy to figure out the remote and operation of this item. Seems to be safe, effective and efficient! Heats up quickly. Will try the cooling method once Winter weather is over.
