I had another AC company come out to do a tune up. Less than 24 hours later, my AC (which previously worked fine) stopped blowing cold air. Alan came out and identified the problem immediately. The other guys had drained my freon. Alan helped me understand the issue and advised me on how to get it fixed... Without charging me a dime. I was able to get the first guys back out to fix the problem they created, but I never would have been able to do that without Alan's honesty. I will be relying on him for all my AC needs from here on out!
