Yesterday our ac went down and we immediately called out mike to come diagnose the problem. He came out after only a few hours and said that a wire had rubbed on a copper pipe which carried the refrigerant and that the pipe had basically burst freeing every last bit of the refrigerant that our unit needed to work. He quickly got to work after offering us a very good price on the job. He welded a new fitting on to where the pipe had the problem and secured the wire up so that it wouldn't happen again. He filled up our unit and bam had us up and running in no time at all. Our home is now back to "meat locker status" as my family calls it. I'm so happy that we called mike! My mom had him out to her place a few months ago and has been ranting and raving about how much cooler her place gets so much quicker. So I would definitely trust mike with my family and that's saying a lot.
