Francis Air Conditioning cleaned the coil on my AC unit. This was my first time working with them, but I knew Alex because he was the salesman who sold me the unit a couple years ago, but he was working at another company at that time. Alberto was the technician who did the work and he was a nice guy. I was OK with the price, especially because it also included a filter. I will recommend them to anybody who needs this type of service in the future.
