+1 to everybody. These are all great answers!

I've really been considering raising my rates as of recent. My mechanic charges $95 an hour. Now, electricians, plumbers, hvac techs,basically any building trade, I feel don't need to know as much about as much as we need to know. Auto mechanics I give credit to, they are the CIs of the auto industry. My guy gets $95 an hour, works in his garage, has his own onsite dumpster, cars get pulled in, get fixed, get paid for, leave. He orders parts, sells parts, they get delivered within 30 minutes of ordering.

I need to charge much more.

As far as stats, I'll put them in, but I call my hvac guy first to make sure I don't mess anything up.
