Terrible Installation.Wanted to install equipment his easy way and not as discussed. Reused refrigerant lines and didn't flush. Didn't purge or vacuum the refrigerant lines. Cut freon refrigerate lines and leaked into atmosphere. This is illegal. Didn't connect humidifier to a usable water connection. I had to layout the route for exhaust installation because he said he couldn't install it there. Wanted to install the AC unit on a patio stone and not on the wall bracket I paid for. Not a professional installation at all. Never have them back into my house again. Very poor or unqualified tradesmen.
