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.

Q:
How much refrigerant is required at installation?
A:
The unit comes pre-charged with refrigerant, so there is no need to add additional refrigerant during installation unless the line set is extended beyond the standard length. In that case, you may need to add refrigerant to compensate for the longer line set.

However, it is recommended to have a professional certified technician install the unit due to the complexity of the installation process. Improper installation may result in the product not functioning properly.
