I don't have a problem at all paying $120 - $150 for fully burdened labor. Employing people is expensive.
Me either… if and when they give detailed rationale for the cost.
When an hvac person can’t provide a comprehensive basis of why it costs what it costs… or an electrician chargers thousands of dollars to have three guys out for not even two hours, and doesn’t even pull the permit…. That’s just thievery. But they have you in a corner so they can.
In the HVAC example I bought tools and did my own install. Easy. In the electrical example, I know I’m not qualified to handle mains power on an un-protected line. So I had to pay. Unhappily.
On the contrary… when I go to get auto body work done, they break out the job to the 6 min timeframe and task. When I get repairs, they quote a time to do it and a price on the parts. While the auto body and shop rates are vastly different for no good reason, they are at least open about what they’ll do and how long it will take.
