Superior Oil Co Inc is based in Millbury, MA. In a 2024 Google review, a customer wrote that their sister-in-law had her boiler serviced by the company, that it had to come back to start the boiler, and that when her heat went off she was told she needed a new oil filter and had to buy one at Home Depot for them to install, while the house was down to 51 degrees. In a 2025 Google review, a customer wrote that the company does not call, text or give a time range before coming out, and does not leave a receipt when it delivers.
If I could leave them less than 1 star I would. Zero customer service. Not a call before they come out, not a text, not a time range, nothing. When they deliver, they don't leave a receipt, call, text, nothing. It's as if customer interaction is an alien concept to them. Good way to chase away business. I don't expect an oil company to treat me like a guest at a 5 star hotel, but some minor acknowledgement and customer service could go a long way for you guys, especially in an industry where the product is the same across the board.
I received call from my sister in law who had her boiler serviced by them four days ago. They had to come back yesterday to start the boiler, I’m not sure why. Today when her heat went off last night they told her she needs a new oil filter. Now shouldn’t that be replaced when a boiler is serviced? But the best part is they told her she has to go to Home Depot and buy one, and they’ll install it. Meanwhile the house is down to 51 degrees. If I wasn’t working today I’d go replace it myself and get her a new oil supplier
