So the technician showed up at the end of May to fix my cooling issue and spent 3 and a 1/2 hours there and he cleaned it out really good, said there were no leaks, put more freon in my A/C system, and put some sort of leak guard in my system. It worked well for 3 weeks only. I called the company back and a different technician came who was there for about the same amount of time and told me that he found a leak! My AC system was empty of freon again which means that the 1st technician never found the leak and now a few weeks after the 2nd technician came I have not had any issues. I still got charged over $300 for something that should have been fixed the 1st time. I will be calling the Better Business Bureau because they charged me again for that service call and it should not have been a charge at all because the technician that came the 1st time clearly did not know what he was doing. So why should I be penalized!!
