Sal and Ruth Mazzaro of Lynbrook are appealing.
The Mazarros say they were somehow classified as a commercial customer.
The PSC says they should have been scrutinizing their bills and rate brochures over the past 41 years.
The Mazzaros said their son discovered the error when he happened to examine the bills in March.
"Hidden somewhere on top they show whether you're a commercial or residential. We never looked at it. So, my son came one day, he says, 'How come you're paying commercial?' I say, 'I don't know. I guess it's what I should be paying.' He said, 'No, you're residential.'," Sal Mazzaro told WCBS 880 reporter Sophia Hall.
National Grid says it "will continue to follow practices outlined by PSC rules and regulations."
