I had a blown 3 amp fuse in the A/C unit, a fuse that costs about 50 cents in any hardware or auto parts store. I am a senior and only recently bought the home, and was not confident enough to try to check inside the A/C unit myself. Antonio was gracious and took only 5 minutes to find the fuse. He charged me $140 for this. For a 5 minute fuse replacement. I am glad for the repair, but I'd call another person next time and hope for a glimmer of compassion. It's only 73 outside today, it wasn't even urgent.
