“John is by far the most experience technician I have work at my house. When he does a job he does it right. He's worked at my past and current home and I wouldn't call anyone else. I recently was away on business and he came right over to help my wife fix the heat issue. I'm very grateful I can call on him.Service: Heating system maintenance“

“I’ve been using this great family business for so many years now and I wouldn’t trust anyone else! They've serviced and repaired my over 35 year old HVAC system for so long, and I finally decided to replace it. They did such a great job, so seamless and efficient and I couldn’t be happier with the results!“

“Had to get a new woodstove and have a chimney rebuilt. I've used Four Seasons for chimney cleaning for years and they are always reliable and honest. Each crew arrived on time each of the three mornings. They took great care in the removal of my dear old stove and were very mindful of my gardens etc. as they worked. The stove and chimney are gorgeous! Can't recommend them enough. Ten stars in my my book!“

“You don't find out about a company when everything goes well, you find the true character when there is an issue. John and team do premium quality work and stand by their work and equipment. I recommend this company with enthusiasm. We have used them at 3 different homes as we have moved.“

“When my mother became ill almost a year ago, I became her Conservator and was completely overwhelmed with managing her estate and healthcare while working and taking classes full time. I didn’t even think to check the oil tank regularly but when I stopped by to check the mail it was freezing in the house and I realized the oil ran out…in the middle of winter. I called Plymouth Oil and without hesitation, they came right out, restarted the tank and filled it. My parents have been with Plymouth Oil for decades and the owners truly take care of their customers, no matter what time of day or night services are needed. The owners are wonderful people who have gone above and beyond to help my mom after my dad passed, and continue to help me now that she’s no longer in the house. Thank you Jessica and Chet! Edy“

“I just had my water heater, furnace and heat pump serviced by Marcus. Super impressed with his work. He was friendly, explained everything thoroughly before he began, and gave updates throughout the process. He was honest and knowledgeable and I will be using JP Parks for all my future needs. Highly recommended!“

“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.“

“Attn: Nick and Bob -
Your employee Bob came out to our house today (Feb 2026) and was an absolute pleasure to work with. We had run out of gas last night and were smelling gas and he came out to check the lines, pressure, etc and restart the pilots.
He was knowledgeable, professional, respectful, personable and patient. He took the time to explain and didn’t ‘mansplain’.
Thanks again to Bob and ‘Mitchell’
Nina and John“

I reached out to request an immediate service of my grandfathers boiler, which had no oil and therefore, no heat.

The technicians who were dispatched to me worked very quickly and were exceptionally friendly.

Thank you guys!“

“I’ve been a loyal customer of Dal Fuel for over a decade, and I’ve consistently received prompt and reliable service. Over the years, they’ve installed a new oil tank and a new boiler, and they always go above and beyond to ensure that the work is done to my satisfaction. Dave is incredibly responsive, even in emergencies, and he’s also very thorough with his work and fair with billing. In fact, there have been occasions I’ve expected a bill and he didn’t send one. I’d be lost without him and his team.“

“Mr. Martinelli and Margaret are close to angels you will ever meet. Years ago when I didn't have hot water for 5 years he helped me with a hot water heater knowing I couldn't afford one I didn't even have running water in my kitchen because I had no kitchen. I couldn't keep up with the house repairs because of no money. Unfortunately after my husband died and my mom at the same time I lost everything and eventually my house and became homeless but I will always remember how he was there for me and Margaret Mr. Martinelli is a strict person but with a big hearrt.

Mr. Martinelli if you are reading this I want to thank you for all you done. God bless you! Narda Castro“

“I have been rehabilitating historic houses for the past 15 years--and in that time, I have used many service professionals for a wide range of repairs and installations. I can honestly say that this plumbing company is the very best I have ever dealt with. The plumber was immediately available, prompt, friendly, communicative, and very competent. His experience and skill were top-drawer and he completed tbe repairs quickly and checked them thoroughly. I was very pleased with the very fair price I was charged--and thrilled to know this wonderful plumber would be available for future work.“
