Thank you for the reply Army Judge.
Today I request an invoice and noticed they charge me 1.5 hours of labor for a total of $180, just to look at the water heater. It's understandable if they drain the tank which take about 45 minutes for this one(been there and done that). It took technician 1.5 hours because he did not know what kind of water heater he is looking at. I had already informed the company what type of water heater it was when I set up the service call.
It only took me 45 to an hour online before I made an appointment with this plumbing company for me to research what type of water heater that I have. The online research told me that almost all the time the reason a water heater stops producing hot water is heating elements and thermostat need to be replaced. When I called plumber I ask how much it will cost to replace the heating elements and thermostat they quoted me a price $250 and $1190 for a new water heater.
After 1.5 hours of mostly TALKING on the phone his diagnosis was that the cause might be heating elements and thermostat might be broken. Replacement will cost $500 and might not solve the problem and so it would be much better just replace the whole tank which will cost $1190. When I had said company quote me over the phone $250. He said $250 is only the cost of materials. I checked the material cost at Home Depot and Lowes and found it for only $35. Even their cost of $250 material fee won't bring up the cost to replace the heating element and thermostat to a total of $500. I asked him how he could justify the cost of the materials to be $250 when I told him that Home Depot and Lowes has it for $35. He excused himself, without having us sign anything and left.
Over a month later they charged me $180 for 1.5 hours of looking at my water heater. Typed invoice did not even have the name of the company and address on the invoice. Is the invoice even valid? How do I know which company that I am paying? This company is sneaky, dishonest, and like to take a advantage of the situation. how could I trust them even I paid in full, I am afraid they would find a way to bill me for something else. What can I do to cover myself? Should I ask them to include the name of the company, address and license number on the invoice? This is corporate, I even see invoice on sole ownership has letter head. what else do I need to ask to include in invoice? Please help!
