I have been a loyal Engel customer for years. I will not call them again and I suggest you do the same.
They told me the water heater the installed in my house is an energy efficient one and it entitles me to a PECO rebate. They were not honest with me, because PECO told me that this particular model does not qualify for the energy efficient category.
They lied and they also over charged me. They have relocated from a Philadelphia location to a suburban one and I guess they want to overcharge customers to make up for their moving expenses.
