I always have a positive experience with Supreme Energy and I want to add the name of Sharlene W. to the list of employees who serve the company with distinction. It is obvious that Supreme customer service is taught by example!

Relationships matter in business just as much as getting a great price. With Supreme Energy I know I am getting both. You don't have to take my word for it - call them up and find out for yourself.

I just want to let Juan's manager know what a great person he is! He is wonderful, professional and respectful! When I opened the door, he introduced himself and asked if he could come in. Within minutes he resolved the problem and he communicated it all to me. I'm very happy with Supreme. What a wonderful company!

Rutherford, NJ

Your technicians, especially Miguel are great and I've never had a problem. I also want to recognize your technician Leo for being very honest and explaining everything that needs to get done. Brad is also very good at explaining things. The customer service staff are always very friendly and helpful. You have a wonderful team of workers and the President of the company, Ms. Fineman is doing a great job running the company. I have recommended your company many times and will continue to do so.

I would like to express sincere gratitude to Brad, who worked on the installation of my air conditioning unit back in 1986! It continues to function today as perfectly as it did back then. The unique custom-made commercial-type air-handler still looks original. Burt Hope, my family, and I are quite proud of you and your work!!! Sincerely, a very grateful client of yours.

Dejana Truck and Utility Equipment

Johnny and Leon go above and beyond to fix all of the problems. One of their supervisors also showed up to help sort out the problem and bring additional parts that they needed. They worked all day without complaining just to make sure that my heat was working. Great team work and great job! Thank you so much.

The technician was excellent! He was courteous, professional, and fast. Eddie is one of the reasons why I stay with Supreme Energy. Please thank him again for me.

Union, NJ

On September 25 your service technician Jose arrived at my house to perform an annual boiler maintenance procedure and assess the system's efficiency. This individual was obviously familiar with the entire task at hand. He moved carefully and quickly. He was clean and orderly. His tools were at hand and he worked with full knowledge of the job at hand. In addition, I watched him and asked questions simply out of curiosity. He answered said questions and was very courteous. Jose is a diligent employee, a very nice guy and an asset to the company.

Paterson, NJ

I just wanted to say what a great service I received from your technician Leo Colon! Leo did a great job fixing an issue I've been having with my furnace since Monday, March 13, 2017. He was courteous and professional and did a great job! I would recommend him for future heating services. Thank you!!

Jim - Secaucus, NJ

I've always had a positive experience. Waits have rarely been long. The service technician Miguel has always been very prompt, polite and professional. He gets right to work and always explains what he did in the regular maintenance. He was done within two hours from first arrival to leaving the house.

Montclair, NJ

I am very pleased to be a customer of Supreme Energy's. When you have a family, it is nice to know you can count on them 24/7, and a live person answers the phone! I was previously a Keil customer. When I was without heat, I would have to wait until the next morning for service. Thank you Supreme for being there for me and my family!

Judith - Ridgefield, NJ

Your technician did a wonderful job. He cleaned my unit so well and was so clean, and cleaned up after himself.

Maria, - West New York

Thank you Mike, the salesperson, and the service technicians who put in a boiler at my house. The Plumbing inspector from the borough examined it and said the quality of work was exceptional. Many companies skimp on the materials and overall quality, but this was a job well done. Thank you Supreme!

Bill - Fort Lee, NJ

I wanted to let you know that I called Supreme Energy last week to get a freon charge for my AC. The woman I spoke to was so nice; she gave me an appt for first thing the next morning. Eddie who came to my house was great, very friendly and knowledgeable.

Marjorie - Florham Park

I'm very pleased with your technician, Gan. He has been at my home a few times. He takes his shoes off before coming in, and he is very good and always cleans up after himself.

Ramon - Linden

The (boiler) install looks picture perfect. The install crew was outstanding. 5 stars in my book. Thank you!

North Arlington, NJ

I wanted to tell you that Leo that installed the hot water heated did a beautiful job--a nice, neat job--and he's also a gentleman. Some people complain about something, but I wanted you to know that I'm very, very satisfied.

Robert, Bayonne

Robert from Bayonne

We have worked with Supreme Energy for years. They are excellent. They know what they're doing. They are thorough, responsive, meticulous and very lovely people. I wouldn't use anyone else. I highly recommend them to all my friends and family.

Chatham, NJ

I go back to 1968 when the oil company was (called) Blondel - then Mitchell, and now Supreme Energy; all wonderful years of service. My wife and I wish Supreme Energy all the best!

Verona, NJ

Just wanted to drop you a line to let you know how happy I am with the boiler installation. Rob and the two Leos are the best team of guys who have ever worked at my house. Professional, knowledgeable and patient with my never ending stream of questions, they did a great job. I especially want to single out big Leo who came by today to troubleshoot a leaking water issue and a thermostat issue and resolved them both. He truly impressed me with his knowledge and varied skillset. I've been a customer for 25 years and one of the reasons I remain a loyal customer is the service I've been provided by your entire team and especially these three gentlemen. Great work guys!!!

East Hanover, NJ

I am writing to thank you for all that you have done to oversee the installation of the of the above-ground oil tank. Your knowledge and willingness to answer any questions I had put my mind at ease and made the experience very positive. In addition to your great service, I want to thank Leo and Frank for the work they did installing the tank. They were very friendly and worked diligently. Also, they took the time to clean up before they left. I will be more than happy to recommend you and your company to anyone I know who is in need of a service that Supreme Energy, Inc. provides. Thank you again for everything.

Honesty, Integrity, and Trust - I know I can always expect that from my energy consultant. It is a pleasure doing business with Supreme!

Service technician was very efficient. An excellent annual maintenance visit. Thanks for 60 years of service.

Bloomfield, NJ

It's the end of the season and I just wanted to tell you that I've been very pleased with your service this year--just like all the other years I've been with you.

John - Jersey City

I want the owner and the tech manager to know what a great job your tech did. He was very clean and very pleasant. He took his time and did not rush.

Salvatore - Bloomfield

I am so delighted with Supreme's installation of my oil tank. Rob figured out a clever way of getting around the narrow access to my basement, your sales support team got my permits through quickly, and Leo C. and Jamel did a wonderful job on the installation--taking pains to locate the tank exactly where it need to be by code and still look good even though it's just a basement. They cleaned everything impeccably before they left. And I think they are the first and only workmen I've had in my house who remembered to turn off the lights. Thanks for everything, Supreme.

Rose - Denville

I called Supreme Energy because my boiler wasn't working. I'm so happy and impressed with the quick response - my problem was handled swiftly and the new equipment looks great. The servicemen, Leo and Vinny, were neat and professional. Thank you Supreme!

Ed - West New York, NJ

I wanted to give praise to a few of your employees who have helped me out tremendously in the last couple of weeks. This all started with call to the Debbie [in customer service]. She was delightful. Well, you all are. Everyone I speak to is wonderful. Dealing with Supreme Energy has been good, really good.

MaryAnne - Jersey City

I wanted to acknowledge the five star work that Leo performed on my furnace on May 16. Leo took the time to explain the service he completed and discuss ways to continue maintaining the efficiency of the furnace. In addition, he cleaned the furnace better than any other technician. Thank you Leo!

Stephanie - Union, NJ

I want to let you know that when I had a new hot water heater installed I had to get it inspected by the fire department. The fire inspector said it was done perfectly; and it was one of the best installations he had ever seen. I want to send special thanks to Leo, your installer and Larry, your salesperson. I want to thank Supreme Energy for doing such a wonderful job and for always helping me if I need you!

Berkeley Heights, NJ

Your service is the best and the men who work for you are great. I have been a customer for over 40 years and I just wanted to thank you for being such a good company!

West Orange, NJ

Your driver, Anthony, is such a nice man and very polite.

Fred from Montclair

I want to let you know that your service people are excellent and wonderful! Abel Guzman, who has been to my property before, came this morning and adjusted the water flow on my boiler - which was installed by Supreme, of course! I've been a Mitchell Supreme/Supreme Energy customer for 35 years. I just want to say again that Abel is just wonderful and I'm glad that he's a part of the Supreme Energy team. Thank you so much!

Liz - Springfield, NJ

We are new customers of Supreme Energy and former customers of Tullo Oil. I have to admit, I was shocked and sad when hearing that Tullo had been sold, but I have been so impressed with Supreme Energy! Our first instance was when the heat would not go on the night before Thanksgiving. We had a house full of relatives coming over the next day and there was a lot on my mind. We called Supreme and a service tech showed up within an hour and reconnected a loose wire. The second instance was when I called on December 26 and spoke to Zoraida. Even though it was a holiday, she was happy to help me with my problems. We had a lovely conversation, she resolved my issue and she asked if there was anything else she could help me with. This was great! Customer service with a smile! What a concept. The third time was March 14, the day of our winter snow/ice/sleet storm. The company actually called to see if all was okay. This was amazing to me! I can't believe the company reached out like that. Thank you for making the transition seamless and pleasant. We look forward to being long-time loyal customers. I appreciate and respect your values. I cannot say this about most companies we deal with these days. It is how I grew up and how things should be. Keep up the good work! It truly is a pleasure doing business with you.

Jersey City, NJ

I had my central AC tune-up scheduled. I received a call to let me know the technician was on the way. The tech actually arrived on time!! He was extremely professional and I was provided a detailed review of my central air conditioning unit. I've been a Supreme Energy customer since 2013 and highly recommend their services!!!

Roger - Hawthorne, NJ

I have been using Supreme Energy for approximately 30 years during which time I have always received excellent service. The technicians have always been prompt, courteous, friendly and professional. Whenever an unexpected problem occurred, it was corrected in a prompt and efficient manner.
