MITCHELL FUEL IS ABSOLUTELY NOT TO BE TRUSTED WHEN IT COMES TO RELIABLY FILLING A TANK AN AUTO DELIVERY. I have had 3 run-outs in the last 1214 months. Additionally, when my propane furnace kept overheating it took six plus weeks to diagnose and solve. When I called to request an adjustment for fuel usage, no response. read more

I have passed this location on lower Federal Rd in Danbury many times and never noticed it. I always thought it was just the heating oil truck location. Great price for gas, multiple pumps. They have a small convenience store located next to the pumps. I really liked the Digital Touch screen which showed you the price and how many gallons. read more

See all

The service is amazing, and the food is excellent -- homemade, fresh, and outstanding. I am returning customer. My another (fourth) big celebration is coming. I trust this place. The owner is very polite and professional in his communication with customers. He always meets my requests without pushing his own priorities. The prices are very reasonable, and the atmosphere is cozy, family-oriented, and pleasant. I highly recommend this place for a family or friends dinner, as well as for larger events. Thank you to the Golden Leo team for an excellent job! read more

I've only been a customer for 6 months after switching from another provider and it's really nice to see the difference. Deliveries that actually come with no issue and no required calling or follow up. Maintenance people that are curteous and take pride in their work. A service number that actually picks up the phone. 5 stars I plan to be a customer for a long time. read more

So I 100% recommend Mitchell for all your gas, propane and heating oil needs including fuel and equipment. Why? Dee and her team of professionals are awesome and their prices great. I used brand X for 12 months and totally over paid until I found Dee and Mitchell. If you don't talk with them you will be missing out on establishing a great relationship that goes far beyond the initial sale. read more

We have used Mitchell for years! Mario was here today to fix our system. What a nice guy! Very professional and quick!

Terrible customer service; the reps have unprofessional phone demeaner, and deliveries are always late and require tons of follow up. No receipt is every left when fills are made. We paid for a fuel delivery and 3 days later still have not received it with no explanation! This is unacceptable especially in 15 degree weather. The weather was an issue last week but the roads and driveways are now cleared. An apology and thank you for being a customer would go a long way- but this company doesn't give those! read more

When a major problem with our 45 year old oil furnace was discovered (leaking heat exchanger) we had to replace the entire system; we also switched from an external a/c unit to a heat pump. We had been using Burke Energy since 1977, and discovered that while in late August 2025 Burke was charging $4.48/gal for the heating oil, Mitchell was charging $3.29/gal, and several other companies were also in that range. We went with Mitchell, and they came the day after the new system was installed to inspect. We're now with them for heating oil, and also for propane to run our generator. Top notch people. read more

I cannot say enough good things about the service I get from Mitchell. I have a very labor intensive heating and cooling system (3 AHUs, high efficiency boiler, ducted and under-floor climate control systems). I have an annual service contract with Mitchell for the heating system. Had a repair scheduled for today which became very involved due to the complexity of my system. Mario, Chris, and Steve spent the afternoon making everything right. I was very impressed with their work. And, as always, they were very professional and pleasant to interface with. Great people to work with. Highly recommend. read more

Got my Furnace serviced by Mitchell Oil & Propane. Ruben the Technician was Professional, Technically Terrific & Respectful. As a matter of fact from when I call the office, I was handled by Jonell who is always there for me as is Joe V the Delivery Driver who has never left even a teaspoon of Oil on my driveway. I strongly recommend this company, Joey Barca, Southbury, CT read more

We recently lost heat in our office and call Mitchell per our service contract. We were given a window of time for which the tech would respond and, since our staff had to work in a less-than-favorable temperature, we performed some rudimentary troubleshooting. We found that the boiler's ignitor had failed, and we called Mitchell to provide this information. We were treated professionally, not talked down to, and assured that if they had the part in stock the tech would bring it with him. They did and he did. We had our boiler back and working soon after his arrival. We truly appreciate the service and professionalism. read more

Great family run biz with caring service. They go out of their way to make things right and always with a smile on their face.

Previous customer they would show up for confirmed appointments on time. the issue is they overcharge on everything from propane to service. like most small company's they are entrenched with family members running the company. They need to hire Some new blood . read more

After my Yelp review Mitchell did in fact reach out to try to come up with a resolution. Since the work they said was done was not complete I had asked for the bill to be dropped in which I got a written response of "My goal is to get this bill off your account entirely" from Tim. I had asked for a written resolution but they would not do this and only offered to speak on the phone which I repeatedly said I did not have any interest in. Low and behold after that I receive a new bill in mail with an additional fee attached read more

We were without heat, we called Mitchell Oil who ordered our new boiler and installed it immediately. There was constant communication.They showed up on time, the work was done properly. Another great job ! I feel the term 'customer service' has, at times, lost its meaning. You restored my faith in businesses taking care of their customers. Thank you John Busch and Mario you were just wonderful. This is why we are long term customers. Denise S. read more

Been relying on Mitchell for over 25 years now. Honest and dependable. Their servicemen are polite. Their budget people work with you on pricing. Never run out of fuel. When my burner failed in the past they showed up to fix it within a couple hours. Honestly couldn't ask more. read more

I woke up to no hot water. Ugh. Im a renter and my landlord needs to approve the service and any charges that a repair company makes. I emailed The Mitchell rep I had communicated with in the past, Stephanie, knowing that they needed permission to do work. It was around 7:30am. I informed her of the problem and provided the landlord contact info again. By 9:30 am she had communicated with the owner and got permission and arranged for a service call. By 10:30am they arrived. By 1:30 pm the problem was fixed. Communication was great. The customer service was exceptional, and they made this repair quick and easy. Very pleased all around. read more

Wow, what an unexpected pleasant surprise, an honest and responsive oil company. After dealing with 3 or 4 other companies in the area, I'm so happy to have found these folks! read more

Mitchell has just completed conversion of our house from an oil-based system to propane -- installing (1) a new Frontier EK-1 furnace, (2) a hot water tank with indirect heating from the furnace, (3) three 100-gallon propane tanks outside with piping to the furnace; and (4) hot-water baseboard heat in our basement. We are very happy with the process and the result. The salesperson, Tim came promptly to our house and took only a few days afterwards to provide a detailed quote. Tim then answered our many follow-up questions and made a couple of adjustments to fit our requests. The work proceeded on the dates Tim indicated and according to Tim's estimate. Tim also came on-site as the work began to ensure things were in order. Throughout the installation Tim was constantly available and very responsive -- working to handle various small requests and ensure our satisfaction. To handle the various parts of the installation and removal of our old oil tanks at least 10 workmen come to our house at various points -- both Mitchell employees and contractors. All were all thoroughly professional and did excellent work -- we are very happy with how the system now functions. We are also very happy with the Mitchell financing department who worked efficiently and politely to get billing and other things setup. We considered many companies before selecting Mitchell, and as these comments suggest, we are highly satisfied with our choice. read more

Mitchell is an excellent company to do business with. We have propane delivered for our fireplace, which is our preferred main source of heating. Their service is the best! Their prices beat the competition. They will Not lock you into a contract. The delivery workers and technicians are the most efficient and polite. The staff I've spoken with are intelligent and very focused on customer satisfaction. Their billing system is flawless. CHOOSE MITCHELL FIRST so you don't have to endure what I previously dealt with, with a different company: Beware of other companies around CT that lock you into a contract, have bizarre written bills and staff who, when you speak to them on the phone, are confused and unable to explain the bills. read more

On 4/26/I7, I requested a service call for our central air unit and got a same day appointment. They were able to fix the problem in a quick and professional way. We use Mitchell for our oil and propane but now will include our central air system. Thank you Mitchell! read more

I had a problems with Mitchell initially but once I had a supervisor involved things started working out much better. I used to have trouble getting rates and pricing in writing but I am noticing an improvement with this and am crystal clear now. In the past, the "gas guy" did not speak to the "oil guy", but since getting a supervisor involved, I no longer hear "that is not my job description". Indeed if you go up the food chain you will get great service at Mitchell because there are people there who care. read more

Great experience. Even though we weren't a customer they came to help with our furnace. They guy was very friendly and quickly got it running again. We'll be switching our business from Kaufman over to Mitchell. read more

Mitchell Fuel has caused me many problems over the past several years. Firstly, last year they neglected to tell me they couldn't get up my driveway with their truck in a snowstorm so I ran out of propane! This year their prices have increased tremendously. I was paying off my bill and made a payment two weeks ago and then another today. I have one more payment to go and they refuse to deliver any propane unless I pay in full each month! In addition, they never leave me any indication of the amount of fuel delivered even though I have asked them to do that quite a few times! They have no heart or compassion and their communications skills are terrible. I am hoping to change to another company as soon as I can. read more

Maybe a good company, but don't bother calling if you need service asap and have never worked with them before. Otherwise..."we can open an account for you and schedule a visit in 3 weeks..." read more

Wow just moved to Danbury and coworker recommended this company! Stellar service! This summer is hot and you have humidity in Connecticut! Not used to it! My condo is so cool with the air conditioner they installed! 5 stars. Quick fast efficient service! Thank you Mitchell! read more

Mitchell Oil is an awesome company!!! I have been a customer for 12 years and always received top rate service. They service our HVAC and pool heater and deliver our heating oil and propane gas. Their technicians are very knowledgable and highly qualified, and their customer service can't get any better. They recently installed a new boiler in our home and their work was timely, neat and very professional. I received estimates and detailed information on 3 different boilers prior to making my selection. Whenever I've had heating or a/c problems, a technician would come the same or next day! And their prices are fair and reasonable. I highly recommend this company for all your heating and cooling needs! read more

We recently had a problem with our oil burner and though we were not currently a service customer of Mitchell, they were willing to come out on a Saturday evening and repair our oil burner. As a result they will get our oil delivery and oil burner service business because it's clear that they have a very customer centric attitude which is hard to find these days. read more

I have been a faithful customer of Mitchell's for years. My advice to you is to request Kevin. I believe he is their top technician. I have never had additional problems after he fixes whatever need be, but have had some additional problems when other guys come to my house to do the job. Kevin is the man and he knows what he's doing! read more

Great customer service for several years I was a customer. Great pricing, came out during emergencies when I needed them, and even when we were moving away, promptly and closed my account and took my final tank reading for the lawyers on the day we had scheduled, no issues. A+, I recommended them to the new buyers as well. read more
