I have been using Air Professional Associates, LLC for over six years now, ever since they went by a different name. I recently had them come out to do a tune-up of my air conditioning unit when they found a leak in the system. They suggested some alternative solutions to the problem, but when they came back they provided me with a new solution I was pleased with, which was to replace the whole unit. It was 31-years old so it was a good idea. Their installers were excellent and I was very satisfied with their work.
