  • Phone controlled temperature- So Cool!!!
This mini split is working wonders for me. It does a really good job of cooling our area and I love that it can also heat it. It did take a little bit of work to install the thing but thanks to some nice helpers we got the job done. I like that you can control it with the remote, but of course eventually we will lose that and luckily we can also control it with our phones. The noise level is impressive, not disturbing normal conversations. Overall it does a good job and exceeds our expectations. I’m happy. ... show more

  • Heater does not work
The heater does not work really at all and constantly turns off after anywhere from 10-60 minutes randomly?? It is 28 degrees outside and I can’t get an insulated room warmed up. The room is only half the size it’s rated for and I just can’t get it any warmer 45 degrees. All electrical and install was done by professionals and both claim it’s a bad unit!! So now I guess I’m out all that install money x2 🥴 ... show more

  • Well worth the price!
Easy to install and very happy with the performance. Heats and cools Great! Nice looking unit! Make sure you use a vacuum pump to evacuate the lines before you open the service valves! Good value for the money.

  • Indoor unit mounting is garbage
Amendment to my original post: This install has been problematic but finally successful. The bracket issues were resolved and fortunately there was no damage from falling off the wall. I found out later that my helper had actually caught the indoor unit before did any damage. We added some small brackets to the wall above the unit to keep it from moving up and falling. On the bracket add additional screws as close to the top and bottom of the bracket to help reduce its flexibility. They recommend at least five screws to mount the bracket I have thirteen. Had trouble pulling a vacuum but a nitrogen test found a leak on the low side that Nylog Blue resolved, so all fittings are now sealed with Nylog. Once the system is up and running the next issue is connecting to WiFi. Instructions are bad and useless. QR codes are all invalid. Was able to manually connect the low grade app to the unit. It has been quite the task getting this unit mounted and working but it is working and seems to be doing a good job so far. Original Post: The small and very easily bent bracket does a terrible job of holding the unit snug to the wall. One wrong move with the lines on the outside will cause the whole indoor unit to fall off the wall. The indoor units outer shell does not come off at all (which is strange) so installing to the small bracket is quite a challenge especially with the copper lines installed. It turns out to be a guessing game if it's mounted properly. Instructions were obviously written by a lawyer since it's at least 75% warnings and the rest is vague on wiring having to cover multiple units without clarity. (I've removed the snarky remarks since they don't help anyone.) ... show more

  • Poor instructions and no mounting template for evaporator.
Instructions are very poor in the enclosed booklet. Sentences are not structured correctly into English from the Chinese company. The QR code that is supplied does not function correctly. Comes up with an error code. Installed and functioning as designed. So far so good. Just a DIY person but successfully installed and functioning. ... show more

Really great value and easy to install. Love that it's precharged with freon. I bought vacuum kit with pump,guages,hoses and low pressure adapter. Great for DIYer's. Installed in my daughter's house right before cold spell she's loving it. House is warm and don't have to use the electric heaters. Took old heater out planning to put port hole window where hole is.

  • control the temperature remotely from my phone.
The media could not be loaded. I recently installed the COSTWAY 18000 BTU Mini Split Air Conditioner & Heater, and it has exceeded my expectations! The WiFi-enabled feature is a game-changer, allowing me to control the temperature remotely from my phone. It cools my entire living space efficiently, and I can really feel the energy savings with its 21 SEER2 rating. The sleek black design blends perfectly with my modern decor, and it’s quiet, even at full capacity. Highly recommend this unit for anyone needing a reliable and energy-efficient solution for larger spaces!" ... show more
