My AC went out on a Sunday night and, although no one could come Sunday, they called me first on Monday morning. They told me between 1 - 4 and he actually called at 3pm and came. He diagnosed the issue and fixed both the initial ptoblem as well as the real issue he found after he started back up the system. He did a thorough job and was not only able to fix the unit but to clean it and get it running optimal so it was not using as much electric. Unbeknowst to me, the reason for the electric bill to have increased so much was due to the inefficiency in the AC unit due to coils being dirty, etc. He was very personable and didn't try to up charge me for all kind of unnecessary services like most companies do.
