COSTWAY 9000BTU Mini Split Air Conditioner& Heater, 17 SEER2 208-230V Wall-Mounted Ductless AC Unit Cools Rooms up to 450 Sq. Ft, Energy Efficient Inverter AC with Heat Pump (Blast Series)

I had the mini split installed in my garage and it has made a huge difference. I needed something that could heat or cool the space quickly since I am not in there all the time, but when I am, I want it comfortable fast. This unit absolutely delivers.It kept the garage warm all winter, which allowed me to keep working out and doing DIY projects. Now that it is warmer, the cooling is just as fast and effective. It is also incredibly quiet.Installation was smooth. I hired a professional, but it looked DIY friendly with clear instructions. The system looks sleek on the wall and does not take up much space. I also love the smart features. It works with Alexa and has a remote, which makes it even more convenient to use.

Very satisfied easy to install my wife and I did it in an afternoon. Very quiet it exceeded my expectations. The spring weather we're having is up and down on the 80 degree days the ac works really well we've had a few nights where the temperature was 30 with frost the heat performed great 72 in my living room dining room kitchen also down the hallway to the bathroom and bedroom. I had a vacuum pump so that worked out all in all Very good system

I have a rental property that are two bedroom unit. this AC unit is absolutely worth every single penny.its light, small and easy to install. yet, it has 12000BTU (which is 1 ton in US AC slang), which is sufficient for 1000 SQFT of space in GA's hot summer.most importantly, it is QUIET. it has no more noise than a fan when its running. so you can barely feel its running.there is NO comparison to old windows AC unit, when it start, it can wake you up at night.it also has remote and phone app so you can program it, schedule it.

This unit is supposed to be able to hold a set temperature. It does not. Contacting tech support revealed u cannot talk directly to a tech. You tell the problem to a receptionist who then passes the info on. Its like whisper down the lane but worse. The responses were never in anyway helpful resulting in multiple contacts with no help at all. Finally, I sidestepped the provided customer service number and contacted Costway through their websites contact info. They responded that the unit will maintain a temp of 78 in cooling and I think 72 in heating. If that is the only temps it will automatically maintain, then that's not helpful. Mine does not automatically maintain any temp in any mode. I called an ac repair tech and he says the circuit board isn't functioning. Now we begin the process of trying to replace that. I'll add to this when I find out if the unit will maintain any set temp, and how Costway does at dealing with the circuit board.Update 10/17: Costway has no service team that could assist my AC guy in trouble shooting the problem. They also have no parts to repair the unit. They suggested submitting a warranty claim. I'll update this post.Update: Costway refunded the money after making multiple videos showing the unit malfunctioning even when the temp was off by ten degrees. They kept making excuses when it wasn’t functioning within 5 degrees of temp. They did not require me to return the broken unit.

It works well for my bedroom. It cools the whole room efficiently and the temperate is well maintained as set. And the noise is minimal, you will not notice it.Besides, the manual is detailed with sufficient instructions for the installation, though I also get a hand from my friend. Overall, it is not difficult to install it.Highly recommend it for its quality and acceptable price!

This air conditioner is amazing! First of all, it’s very quiet, and second, it doesn’t block the window, so the room gets much more natural light. My old window unit was not only noisy but also let bugs crawl in through the gaps, which was really annoying. Now the window can stay fully closed, and the cooling is fast and efficient.

Installed this mini split in my insulated garage in Colorado. Product is mainly to be used to keep my dogs warm and my garage usable in the coldest/hottest months out of the year. Very much a DIY project if you're somewhat handy and know your way around electricity, takes a day/long afternoon, only time I needed to call someone was to vacuum the lines and check them for any leaks. In the instruction manual, it says the mini split will not operate below temps of 9 degrees Fahrenheit; not the case. I fired it up this morning at 2 degrees, windchill of -8, and it ran like a champ. No problems at all, and still kicking out decent enough heat to make the garage bearable. Bought mine on sale during prime days, and for the discounted price, I'd say more than worth the investment. The app doesn't work very well at all, and I don't use it, hence 4/5 stars, but certainly not the end of the world. Time will if that statement remains true, but I'm kicking myself for not doing this project earlier, what a difference it makes!

I purchased this air conditioner looking for something both efficient and affordable, and it exceeded my expectations. It cools the room quickly, operates quietly, and was straightforward to install. It’s ideal for medium-sized spaces. Compared to other units in the same category, the price was exceptionally reasonable. I’ve been using it daily without any issues. If you’re seeking quality performance without overspending, this unit is a solid investment.
