“We had purchased a wood stove to replace the one we had used for 30 years. Anthony and Leo showed up for the install and they were great. They were efficient, professional, and courteous. We had two other companies come prior for estimates and they spent most of the time boosting the original install to between 3k and 5k.... Fireworks stayed within the original estimate which was about one-third the cost of the others. These guys were great...honest... took the time to explain everything.... The whole experience was fantastic..... Thank you.....“

“A few years ago I moved my business to JJ Sullivan because of their reputation and I have not been disappointed. They installed a new furnace and the workmanship was outstanding. They respond almost immediately to any inquiry. I am often away from home but I trust them that if I need them to respond they will. Good old New England service from a family business. WAY worth the few extra dollars.“

“Great company. I literally left my old LARGER oil/service provider for them. Previous company I even had an active contract with wouldn't even return my phone calls for a safety issue. When I had an inevitable service emergency Pennywise had amazing Patty who was friendly, attentive, and did everything she could to help me and my family before I was with them! After signing the contract, the technicians were shockingly proficient, courteous, and responded quickly to my situation. I couldn't be happier with the results. If I was with my last dismal oil company for nine years, I can only say at this time that I will likely be a lifer with Pennywise.“

“I needed assistance to deal with an emergent boiler service. Fred Jordan showed up the next morning and corrected the problem in no time. He then noticed my more than 70 year old steel oil tank that was on it's last legs. He replaced the tank and really demonstrated his expertise and workmanship. The price was very fair. I highly recommend Accurate Boiler.“

“Excellent, knowledgeable plumbing and hvac pro. Came within hours of our call, investigated and solved the issuein within 1/2 hour. Charge was way below expectation. Definitely would call again, and trust his expertise and meticulous style, without question.“

“Just received my delivery today and I have to say this is the most pleasant oil company to deal with. From the woman that answers the phone to the delivery driver! Thank you

“Maus has been WONDERFUL for all our plumbing. While taking care of my grandma's property (sept 2020), the water heater went out. Called a couple other local companies but no one was as accommodating as Maus. they Did an amazing job, and I found out later they were my grandmas number one pick for plumbing! Should have asked her to begin with, hah!“
