If it is any help, let me tell you what I found while working some jobs the past month, One customer needed a gas appliance hooked up they called the gas company, when he srrived while we were there, he came in with tool box, took him about 6 minutes to attach gas line, another 5 to write up invoice, she paid $159 plus tax, no hourly rates just a flat amount.
Another job we were on an appliance repair showed up, they were there for an oven repair, the man came in looked at the oven 4 or 5 minutes at best, told the lady she needed a new oven, and presented a bill for $139 plus tax, his total time there was about 15 minutes.
Another job we were installing a line for a sump pump, when an AC repairman came to the house, he took about 5 minutes looking outside, came inside opened the air chamber and replaced a filter, the owner touted how good he was, only $279, well for 20 minutes of work that was not bad.
This friday, we were replacing smokes, and installing an outdoor light, when a plumber arrived, to replace a toilet seal, he was there for almost an hour, $290
Then the electrician shows up, diagnoses the problem, gives a free estimate and leaves with nothing.
