That’s about what our company charges. It may take 1 or 2 hours to diagnose before they either have it fixed if it’s something minor or know what the problem is and can discuss possible solutions if it’s something big. We start billing when we receive the job ticket to start driving over to your house, so if it’s a half hour drive then they will only have half hour to set up tools and troubleshoot before that first hour is completed.
As far as the breaker goes, mentioned above, if it has tripped then there is something wrong. It should never trip under normal operation if everything is working correctly. Let the tech know if you reset the breaker or attempt any repairs before they get there. Don’t be too proud to admit a mistake if you made one. We look for clues when we are diagnosing problems and if you start changing things without telling us then it makes it harder to troubleshoot and can in some instances lead to a miss diagnosis. We are there to fix your problem and appreciate every bit of information you can tell us, no matter how insignificant you think it may be, to help us get the repair done as fast as possible. Let the tech put the pieces of the puzzle together to determine the required repair.
