We called the company to request for a leak check because there was oil residue on our AC. They advised the tech will come out to check and then recommend what is needed. The tech came out and we asked for a leak check which was not done properly and then we have video and audio recording of the tech stating all leaks are fixed and then he put freon in the system. We still have a leak and the company is saying that the freon is not covered under warranty even though we paid $450 for freon that leaked out because of their negligence and improper service repair. They then said they will send out a tech for a second look but still wanted to charge us for the leak check and to refill the freon. I have a lot of evidence that this was a poor service and even have their own tech saying they hired a bunch of new guys that he has to continuously go behind to fix their errors but yet they have no ethical morals to repair and admit fault. I emailed the whole issue to them but they refuse to do what is right. I would like a refund of the service charge and a refund for the freon that leaked out since they didnt fix the issue. This is not the first time they diagnosed an issue wrong. They replaced our fan in our brand new central ac when that wasnt even the issue and we have 3 or more home visits for them to properly diagnose that. Their argument is that the leak is no in a different area which means you didnt do the proper diagnosis that we requested to begin with. It is your techs fault and we need to be covered under the warranty of you not fixing the issue. I can provide any audio/video proof to show the facts and not the lies of the company. Oh and the tech that came out for the second look left our ac taken apart and not properly mounted to the wall. He said he had to leave now so he didnt even fix what he took apart and had a poor attitude and said he left because his boss told him to leave and he has to listen to his boss.
