Bill Trombly Plumbing Heating Cooling Electric

I called Bill Trombly on a Friday night because my hot water heater stopped working.  I started to pull the thermal coupling out to see if that was the issue.  As soon as I pulled the unit, I realized I had never seen anything like this unit before and called for help.  The representative walked in and looked at the unit and said he couldn't do anything.  He then charged me $125.00 for the trip.  The following Monday I received a phone call from the office and they quoted me over $400 to fix the burner unit (which included the burner, thermal coupling, pilot, and igniter.  I thought this seemed high and called the hot water heater company direct and was able to obtain a new part for $119.  It took me 16 minutes to change it out and put the new one in.  I understand companies need to make money, but that much for something that would have taken them less than 16 minutes is unbelievable.
