"I hired this company to check an error code on my water heater. They informed that the anode rod needed to be replaced or I could just replace the entire water heater. They gave me several quotes including $4800 to replace just the anode rod or $4500 to replace the whole water heating unit, but wouldn't show me pricing details. I told them to move forward with the repair and afterwards he could walk me through the details of the pricing. They charged my card for $4127 plus tax. I asked to see an itemized invoice and was told I would be sent one when the technician completed his notes. I later received a one line item invoice for $4127 plus tax for a 50 gal electric water heater replacement, several photos, and nothing more. I looked up the retail cost of my new water heater and it is only $825. The average cost in my area is $1000-$2300 for installing a replacement water heater of its size and kind. This company will overcharge you. I?ve filed with the AG for price gouging. "
