They charged me $350 to replace a $10 thermocoupler. It took the guy less than 20 minutes to diagnose and replace it. I was in a time crunch so I had to pay it. Two other plumbers told me later that they do they same job for under $200 and $150 respectively. I talked to ""Roger"" on the phone and he just hemmed and hawed about the price. I will NEVER call them again. I suggest you call someone else.
