I must of said this 100 times, service calls are not the same as scheduled jobs, and the dispatch fee, comes nowhere near covering the cost of dispatching an electrician.
When our washer had problems, we called for service, they gave us a date with a 9AM to 5PM window, they also put a $90 charge on our credit card, before responding to the call, no credit, no response, they know eniough from years of service experience what it takes to run a service business.
The day of the service call I happened to be home, when the tech arrived, he came in and went to the basement, checked the machine, and wrote up a repair quote, I would not have to pay another call fee, if I accepted the repair work. He was there a total of less then 15 minutes. I asked him how many of these calls do you usually do in day, he said it varies, but between 6 and 8
Now remember these are appliance techs, not electricians. Where talking about a real business that generates income, and is able to weather the changing market place, not someone working for a paycheck, with no means of building a business with assets. Bottom line an efficent service company needs to produce cash flow and profits, to continue in business.
