Years ago, I had an air conditioner emergency, and I called the first name in the book. That was A STAR Air Conditioning, and I have been using them ever since. The last time that they came out, it was just for the routine service, but they ended up having to flush out the line, too. From the person who answers the phone, to the people who show up to do the work - and these people have changed over the years - all of them have been polite, considerate, friendly and competent! And, they have given me excellent service!
