I had a leak in my air conditioner and got a quote from another shop on S. Mason that the repair was going to $325. I went to this shop to see if they might be cheaper and THEY WERE! Just $85 to fix it and fill the freon. They just replaced some o-rings for me INSTEAD of the whole part, like the other guys. That was a year ago and my air conditioning runs great. This has happened again and again with them! They stay late to finish your repair and are very friendly. The place is really small but you can tell that your business matters.
