★★★★★ 5.0 Bob Rallis · Feb 2026

I recently had an issue with my heating system, but after a quick and helpful phone call with their team, we were able to resolve it remotely. Everything is running perfectly again! I highly recommend their services. They were willing to make the hour drive to my house if problem wasn’t solved

★★★★★ 5.0 Sue W. · Nov 2023

We recently renovated our home, and had the immense pleasure of working with Angelo and his team at ThermOil to design and install both heating and cooling systems. We were consistently impressed by the character of the employees (honesty, integrity, humanity), their evident skill and commitment to doing a good job, and their capacity for patient and effective problem-solving. I am beyond grateful that we had the opportunity to work with them, and that we have such a reliable partner for annual maintenance, etc. going forward. I recommend them without reservation as a great value!

I’ve been a customer with Thermoil for the last 25 years, always had the best service anytime there was a question or problem they were there to solve it. So naturally when I decided to do the massave rebate program for the mini splits, I chose Thermal oil. And I’m glad I did. Their technicians were amazing. They were always on time, extremely neat and clean, every time I had a question they made sure they answer it properly and put me at ease, most importantly, they kept to their schedule from start of the project to completion of project, and because my wife works from home, they respected the fact that she was around, made sure they were quiet, and she continue to do her job properly from home with no interruptions. Just overall amazing definitely a five star Company. PS I can’t leave o

I called Angelo when my furnace failed the other day. He came the next morning and two days later his crew removed the old furnace and installed a new high efficiency unit. So responsive and professional and very reasonably priced. They did a terrific job. I highly recommend them.

★★★★★ 5.0 Anthony Fonte · Jul 2023

I had a great experience with Angelo and his team who replaced my air conditioning system. They were knowledgeable, efficient, and dedicated to customer satisfaction. The installation went smoothly, and the new system works perfectly. I highly recommend them for any air conditioning needs.
