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.

5.0 out of 5 stars it’s good but be very careful

Double check or triple check your connectionsBuy the sealant for the connections and use itIf your R32 leaks out it’s hell on wheels to get more to replace itit’s EPA controlled and you have a professional A/C technician come to fill it costing more than a new unit

5.0 out of 5 stars It simply works

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.

1.0 out of 5 stars circuit board did not control temp from day 1

l.n. · October 15, 2024

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.

5.0 out of 5 stars Worth the money

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

5.0 out of 5 stars Much better than a window unit! Totally worth it!

We purchase this a little over a month ago and absolutely love it! It's cooling a 14'x35' area of our home. It is super quiet, you don't even know it's there. The outside unit is so smaller than our 1.5 ton HVAC unit that died and friend and family have really been impressed by it.

4.0 out of 5 stars Very efficient

S.w. · June 4, 2025

Has worked very good just a little hard for a normal dryer, I looked it over and hired a professional and glad I did. They put in a shut off and everything to make it look profesdional

5.0 out of 5 stars Good value

V. · May 19, 2025

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!

Very pleased with this unit. Super quiet.

After several attempts and because the unit would still not power on Cost Way suggested we contact a local company to resolve the issue and offered a partial refund to cover for the repair. There was a small wire that was damaged and after being repaired I am pleased to say that our unit works like a dream. Cost Way support was fast and efficient with their response and I would recommend this company to provide your AC needs.

Great units and support

I'm speaking on two units I just installed over the past two weeks so this isn't a full "reliability over time" review.As described, the units arrived in two boxes each (the indoor unit with it's bits in one box and the other bits in the outdoor box).Since the units are economically priced and the performance ratings seem quite good, and I only need heat in the shoulder seasons before I switch to full on wood heat (vs the $$$ electric forced air), they seemed to fit the bill. The heating comment is based on the notes that these will work down to -10C (14F). I don't know if that means the units will cease to work or if they will lose efficiency, time will tell.With all that, I decided to do the install myself. Here is where you learn about vacuum pumps, gauges and oil (another ~$200), electrical cutoffs, codes, etc. Did my research before I ordered and the work involved seemed to be straight forward, including running 12/2 wire and conduit (and a new breaker / etc).Following various install videos and a chat with an HVAC buddy of mine, I quickly determined the best approach and took it, and here's what I learned:- the 2" hole required is going to be a tight fit, so when wrapping with the vinyl, make it tight. If one goes larger than 2", note that the wall cap cover isn't going to fit (as it's 2") and the larger hole will require more filling.- the drain hole in the bottom of the outdoor unit is 25 mm, and if you cannot drain directly out, you will need some extras for it (note the size). I installed my units onto a wood deck so I didn't want the water just running wherever so I did this bit of extra, and here is where you need to know the size, which is in the manual- One has to remove all the plastic protective shipping covering from the indoor head to get the tape off, which has to be done to install the com wire. Make sure to take care when handling afterwards to not mark up the plastic.Once the connections were made, line sets torqued to spec, vacuumed for 15 minutes and vacuum leak checked via gauge, everything in place and electrics connected, only then I opened the valves to release the R32 gas and pressure checked all the fittings again for leaks ( with a 50/50 soapy water solution).Verifying no leaks, time to throw the power. LEDs lit up and with some batteries in the remote, I had the unit pumping out heat within minutes of turning on the main power.The units so far work as planned. The heat stability in the house is better than ever (haven't had to cool with them yet, may update after next summer). They are very quiet, even the outdoor units are near impossible to hear inside, and outside it's mostly a whirring fan sound.Now, why the support comment? One outdoor unit arrived in a damaged box, which I didn't notice until after the delivery guy was long gone. When I opened the box, I noticed that the unit had a considerable dent on the business end (connectors / electrics / control unit). I contacted Costway via the Bolo contact process, complete with explanation and photos of the box and the unit, and in less than 24 hours they had a new outdoor unit on it's way. If I could complain about anything it would be the nearly two weeks to wait for the new unit (same time to get the original one). However as I was not intending to install them right away (and I had one good unit to install currently) and Costway DID CHECK to see if the time to receive it was OK, and it was so I'm not faulting anyone.So far so good, and time will tell. At this stage I'm recommending my friends and family to consider these units as I now know what is involved for the install, and they work well (they are quiet and throws heat, cooling shouldn't be an issue, and reasonable to install with what's provided).

Perfect AC, awesome price, good quality!

We got this installed in our new house, we have the same units in our apartment rentals and they work well! It says it can heat, but it has to be over 0 degrees in order for the heat to actually work. As for the AC it works perfectly, and we did buy it again! We had to have it installed, so I would plan that ahead and ask for pricing. The unit itself is at a great price!

Happy with it so far

M.B. · April 19, 2025

Very happy with the product. I did a self install, and it went very smoothly. Ive had the unit for a month and so far it heats my 400 sq foot tiny home with no problems at all. Not sure how it will do in the really cold weather, but when it hit 0 degrees celsius, it kept my place nice and warm. I used the AC for the first time yesterday, and i had to shut it off, it worked to good. I did by a vacumm pump so i could do the whole install on my own, and i do recommend this product.

Très bonne qualité
