New A.C. unit installed in may 2016 stopped blowing cold air shortly after. Reliance guy came out and topped up the refrigerant and it seemed to work, into this summer when it blew warm air again. Two more guys came out on two separate appointments, then finally Joe Green came out and diagnosed the problem and ordered the part. Reliance the sent out yet another person who did not know what to do with the part. It wasn't until Joe was finally sent round again that my A.C. was fixed. So basically not very impressed with Reliance as the installation of the unit was faulty from the start and no one seemed to know or want to know what the issue was, with the notable exception of Joe who spent several hours working on it. If I could rate his work separately I would give it 5/5. But not Reliance as a whole.
