My a/c was leaking in my basement, soaking the rugs. So I shut it off and called reliable. David called me back promptly and squeezed me in first thing in the morning. He quickly diagnosed the problem and fixed it and also showed me how to fix it again should it happen. He also showed me areas of concern in my unit and we talked about options. He was very friendly and informative. I would definitely call them for all my a/c and furnace maintenance and recommend them.
