I called Black Diamond to provide an annual inspection of my air conditioner. It had not been done in a while and my home recently sold, so I wanted to make sure everything was OK. The guy comes in and I tell him it has been leaking. His conclusion that the pipe in sweating from condensation and he wrapped a small section. It did not solve the problem and after the home inspection I was told the whole section needs to be properly wrapped. Why didn't the guy from Black Diamond do this? Then he went outside to inspect. I see him there for a little while and then he puts his stuff away and is gone. I keep looking out the front door wondering why he isn't coming in or why he is no longer by the air conditioner unit? Eventually, he comes in and give a bill. I ask if he want to put a sticker on the unit to show that an annual inspection had been done by Black Diamond. He forgot and was glad I reminded him since he tends to forget. Really? I feel like I didn't get very good service.
