I loved my other Costway mini split so much that I bought a second one. The first one I use in my living room and the second one is in my dining room. They work amazing and the cost is better than any other brand I have looked at. Ian planning on buying more for my bedrooms.

I bought a Costway mini split for my living room. It is wonderful. It works great. My husband was able to install it in a day. It is an amazing product. The cost was well below other competitors so at first I was unsure about it. I am so happy that I decided to get this air conditioner and heater.
