For what it is worth. E.C> in Mass.
Usually the general service call:
$125.00 service call, includes two men, a stocked truck and the first 15 minutes on site.
Emergency call:
2.0 hour minimum = $250.00. if it goes over the 2.0 hours than 1/2 day rate and if it goes over 1/2 day than full day rate.
I have been on calls to reset a tripped gfci. Five minutes, okay mr./mrs. customer is there anything else you would like done? I have taken out the trash or whatever else for the remaining ten minutes. I don't care what I do. I quoted you a price for 15 team minutes and that is what you'll get.
