We have been doing work with them for a few years now. They go back and forth with paying on time and not. This time around I am waiting on $6,000 and I am beginning to get collections against the company because I can't pay my bills. As a contractor you are out that money until they pay you. Being out thousands and having to wait months is unacceptable. I would hope other contractors avoid them. They tell some customers with parts that are wasted that they're going to fix the problem, and don't for months. They bought 15 or so heaters from me and then the last one doesn't include converting to in door stack, so I have to bill the home owner? Lot of BS going on with them. I hope I get paid this winter.....
