They work fine but they only read in Celsius pretty silly to sell something like that in American market. Really disappointed with that reached out to technical support and nothing they can do.

We bought this COSTWAY 18k Dual Zone Mini Split for our houseboat, because floating on water should feel relaxing… not like surviving the Arctic or a sauna. This system absolutely delivers. My boyfriend installed the entire setup himself. I’d like to note that the amount of cursing was surprisingly low, which tells me the instructions were decent and the parts actually made sense. That alone deserves applause. We’ve used both the AC and the heat, and they are both fantastic. The AC gets ice cold (like “do I need a hoodie?” cold), and the heat is cozy enough to forget you’re literally on a boat. Both zones work quickly, evenly, and quietly...no rattling, no drama. The remotes work great, are easy to use, and respond instantly. My only complaint: everything is in Celsius and apparently I now live in Europe. You can’t change it to Fahrenheit, so be prepared to do some light mental math or just press buttons until it “feels right.” Overall, this unit works incredibly well, looks clean, runs quietly, and has completely upgraded our houseboat life. If you’re on the fence, don’t be. If your partner is installing it... bring snacks and moral support. Highly recommend! Photo note: I wanted to include pictures of the actual mini split unit, but unfortunately I don’t have any on hand yet (houseboat logistics 😅). I did include a photo of the remote, mostly because I was desperately trying to figure out how to switch it from Celsius to Fahrenheit (spoiler: you can’t). The unit itself looks exactly like what’s advertised. Next time I’m out there, I’ll grab some photos of the installed system and update this review.

Had it installed and did great for summer. Air conditioner was good. Heated seems to make noises out of head unit. Turn off and back on seems to work but noise is not nice. Installed in a 16x40 tiny home. I have had it i stalled for a couple months now, and seems to work good other than noise.

This is the third mini split I put in and I’m not satisfied with it. But this is the first cost way and unhappy with the product. Code P7 Sometimes the unit works good on one interior air handler and the other one doesn’t I would not recommend it

Hooked up in a red iron steel building. Does a great job, looks good super quiet. Don't know how long this thing will last but it is doing a fantastic job. So far i definitely recommend especially for the price.
