Jasinski Fuel Service is a Harwinton fuel and heating company, and its owner, Johnnie Jasinski, has been quoted by a local paper on how customers watch their heating budgets. A 2025 customer who had absolutely no fuel on a very cold late evening said they called multiple companies and no one would come, but Jasinski came that night. That customer said that afterward the company reached out and came promptly whenever the fuel ran low. The company's website describes oil, propane and natural gas fired boiler, furnace and water heater installs and repairs, central air conditioning, ductless mini-split and heat pump work, and oil tank installs and removal. A 2025 customer whose system would not start after an oil delivery from a different company said Johnnie told them exactly what tools and equipment they needed and what to do to fix the problem. A 2024 customer with a commercial building said the company identified the problem on an older furnace, found replacement parts that were retrofitted to work with it, and replaced the thermostat at no extra charge. A 2024 customer said the company repaired their furnace and was punctual and courteous. A 2024 customer wrote that they showed up on time, made repairs and left the place clean, and called Dana very knowledgeable. It holds 4.9 stars from 42 Google ratings and an A+ grade from the BBB. A BBB review praises its furnace service but calls its oil delivery horrible and says weather was given as the reason oil was not delivered.
“At Jasinski Fuel Service in Harwinton, owner Johnnie Jasinski said customers are similarly watching their wallets, particularly those living on fixed incomes.”
great company
On a very cold late evening when I had absolutely no fuel, I called multiple companies and no one would come. However, Jasinski fuel not only came that night, but has had the most professional and kindest attitude moving forward. Now, every time I’m running low on fuel, they reach out to me and come promptly. I truly appreciate the kindness and flexibility of this company. They really make you feel like family.
Great experience today! Thanks Johnnie, you were so helpful! We ran out of oil and our system was down for a couple days so no hot water or heat. We had another company deliver oil today, but the system still would not start right up. I called Johnnie as I know he is pretty great at solving issues as long as I’m able to articulate it to him. He was able to tell me exactly what tools and equipment I need and what to do to rectify the problem! To me, having people like Johnnie that can solve an issue with a phone call and a brief description is rare! That man has some serious knowledge!!
I have been using Jasinski for multiple jobs at a commercial building we own and they have provided exceptional service. I would highly recommend them for their customer service and the quality of their work. On a recent job I had at my building, they identified the problem on an older furnace, found replacement parts which were retrofitted to work with the existing furnace, and got an excellent outcome. And they even replaced my thermostat at no extra charge. I consider people to be knowledgeable when they say, "I'm not sure but I'll find out." And then they do just that. Highly recommend for our HVAC needs!
We recently had Jasinski Fuel Service repair our furnace, which is now working great! They were punctual, courteous and very professional. I would highly recommend them.
