Home Warranty Sent them
I was having trouble with my air conditioner and the Home Warranty Company sent them out. The first time they came out,i told them the unit seemed to be struggling. They serviced the unit or oiled the compressor and said everything was fine. Less than 30 days after that, my unit stopped working. I called Home Warranty back and complained. They sent them out again. This serviceman seemed more knowledgeable. He went up in the attic and told me what was causing the problem. He blew out the stopped drain. He then cleaned the unit and it has been working better and cooling much better since. He was much more thorough than the first serviceman that they sent.
