Style: 12000BTU, 115V, 20 SEER2
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.

Style: 18000BTU, 208-230V, 19 SEER2
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.

Ok it has been just a little over 1 year and I can say that this product is amazing. Easy to install I did the install myself and no leaks, the heat and ac work perfectly, and i didnt see a huge change in my electric bill. The filters are easy to clean and the hoses are simple to vaccum yourself. Its super quiet and im impressed with it. Highly recommend.

Style: 12000BTU, 115V, 20 SEER2
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.
