Supreme Energy is a family-owned, Weymouth-based home comfort company providing heating oil and propane delivery, HVAC installation and repair, and related energy services across Norfolk, Suffolk, and Plymouth counties. The company holds an active Massachusetts plumbing license, verified by the state registry, and says it is Mass Save certified and a Diamond Contractor Preferred dealer for Mitsubishi Electric cooling and heating equipment. The company holds a 4.8-star average from 667 Google ratings. Reviewers repeatedly praise fast emergency response: one described a technician arriving within the hour to repair a heating system that failed during a cold snap, another described propane delivered on a Sunday night within an hour of calling, and a 2026 review described new tanks installed within days after a switch from another company. One long-time customer described working with Supreme Energy for close to ten years, from oil delivery through furnace maintenance and emergency calls, and a 2025 review credited Jean by name for reliable, clean new-construction installs. A 2026 review alleged the company would not repair a boiler installed by someone else unless the homeowner also bought oil from them. A separate negative review on the company's Google page describes a dispute with a company called Quarles in Culpeper, Virginia, and does not appear to describe Supreme Energy. Supreme Energy holds a Better Business Bureau A+ rating and shows nearly 1,000 recorded permits on BuildZoom, reflecting a long, active service history; it is a well-established option for oil and propane delivery and HVAC work across the South Shore and Greater Boston.
“Honestly just a great place to work. Bosses are all very understanding of life outside of work. They will always accommodate Dr appointments or anything else that comes up. Great pto. Great benefits.”
“The industries located within the proposed overlay district include Francer Industries on Wharf Street, a private residence at 532 East St., Danubio Repair Services and Supreme Energy on East Street. Francer Industries’ owner has previously indicated he plans to sell its manufacturing building later this year. ... “Supreme Energy has been there forever,” he said. “I’d be shocked if they ever left that land and sold it. Let’s say they did. That lot is so small, you’d be lucky if you got six units of housing on that land.””
If it was possible, I would give them a BIG FAT ZERO rating. NOTE: The Quarles people in the Culpeper office were terrific people to deal with. BUT, the money grabbing very large company closed this office to "walk-up customers". I have several times to get a delivery during the 25-26 heating season. Now my tank is completely empty. Please do not think that I can't read tank gages. Having ridden USN submarines for all most 20 years. I can read tank gages. I also feel qualified to judge their customer service. At my retirement from DLA Energy. I was awarded a White House Award for teaching customer service to DLA Energy and their customers, over 800 people in 14 years. I started the account termination process today. Wonder how long it will take them to get their EMPTY tank and refund my balance????
These guys are professionals! They have taken care of my family in some serious situations! Always respectful and explaining the process! On time and knowledgeable would absolutely recommend them for all your needs!
I called on Tuesday and within and hour Jean called me back. I explained the problem I was having with the other company. By Thursday Paul & Joe came out and set up new tanks for me They were extremely helpful and kind and went above and beyond There customer service is awesome . I cannot say enough about them I would Highly Recommend Supreme Energy They genuinely care about there customers
My heating system broke down during a cold snap. Joe came out to repair it within the hour. He has over 40 years of oil burner experience and was able to diagnose and solve a complicated problem for me. The heating system now works better than it has since I moved in 8 years ago!
Tried to get them to fix a boiler that was just installed on a property we purchased. Basically said that they won’t do it unless you buy oil from us. How’s that legal? My husband got involved and they have hung up on him multiple times as he’s angry this issue wasn’t just something they could resolve as a courtesy of installing it about a month ago.
