DJS AIR CONDITIONING & HEAT

This company came out at the request of my roofer. I was having a new roof put on and the roofer had to lift / move my A/C unit. After this lift / move my A/C unit stopped working. Dave from DJS Air Conditioning and Heat came out, got on the roof, LOOKED at my unit, and told the owner of the roofing company the problem was inside the house and not the company's. Should I have been surprised? Dave was there at the request of the roofer. Dave never pulled out a tool or touched the unit prior to making this assertion. He climbed into my attic and after some troubleshooting said the fuse had blown. I asked to see the fuse, to see if there was some kind of burn pattern on it. Dave refused to let me see it. He told me it was his property and it would cost me $100 to fix it. He then told me if I didn't pay him I would be unethical because he came there and diagnosed the problem. I didn't ask him to come, the roofer did. Dave went on to tell me that he would not show me the fuse so I couldn't go buy it and replace it myself. I don't even know how to open my A/C unit let alone know where the fuse is. So, what sense does that make? I asked him to leave. He was just rude and nasty. He didn't put my unit back together properly and left wires and things exposed. Never will I allow this man or anyone from this company into my home again - EVER. I had another company come out and diagnose the issue. They told me that the roofer could have very well caused the issue. This I already knew because my A/C unit stopped working after they touched it.
