  • Inside unit looks different wifi nit connecting
Inside unit is not like the one in the picture looks different, but it is ok. 20 SEER instead of 21 as described cools really good and is quiet. I was able to connect to Wi-Fi you need to setup as AP.

I would recommend using a tech after everything is in place. ... show more
