The technicians were professional, always on time, and kept everything extremely neat and clean. Anytime I had a question, they took the time to explain things clearly and made the process easy to understand. They stayed on schedule from start to finish, which made the project smooth and stress-free. My wife works from home, and the team was very respectful and kept noise to a minimum so she could continue working without interruption. Overall, an excellent experience and definitely a five-star company. The office staff was also fantastic and very helpful with the loan process and paperwork.

This is a follow-up from my review of ThermOil of Watertown, MA on December 11, 2025…read more ThermOil called me on Saturday March 14, 2026 at 4:09pm from their number of 617-926-0779 and left me a voicemail to call them back to talk which I returned their call. They asked or should I say they told me to me to remove my review of them from yelp because it was bad for their company. I said "Why"?, that's my review of what I went through with dealing with you. The individual told me that he knows my next door neighbor and that we met, he was referring to a party that my neighbor had and had most of her colombian friends over. I responded "What does that have to do with anything"? He went on to say that I said my water heater was not leaking or broken so I told him that I was making a customer call for service and you people never, ever returned my calls. He told me they were busy with "No Heat calls" and I said every company was busy in Massachusetts and I am not talking about the service staff out in the field, I'm talking about the office staff not returning my many calls to them. He told me that they were busy too! I told him that they were too busy to call a customer back? He asked me again to remove my review of them which I responded "NO" it's my honest review of what I went through with ThermOil and told him about my awesome service dealing with 128 Plumbing and Heating in Wakefield, MA. And I went on to tell him that this phone call to me is only going to make a worse review of ThermOil. He responded "So you are not going to remove your review of our company" and I told him again "NO" and he hung up. Well, if I get a knock on my door and some guys from ThermOil tell me they are here to change my mind about my review of their company, I will let you know, lol. This is not Colombia and what tactics they do down in that country do not work well here in the USA. And you know if he said to me that they would do a free service to make it up, things would be different but he stuck to his intimidation tactic. Oh well, they "Live and Learn" in this day and age.

They also promptly returned my 11PM on a Saturday phone call when the burner stopped and smoked when I restarted it. They came out to check it out just to be safe the next morning. Maybe the moral here is that I should replace my 25 year old burner. If they weren't so good, I probably would have had to by now.

I had to operate his…read moretablet for him and repeatedly point out that the information he was looking for wasn't on the unit's label while he constantly told me he wasn't very familiar with Lennox systems, even though I called them because they are a Lennox dealer. I ended up having to help him through checking everything. I eventually got an "estimate" that included overpriced repairs that cost as much as replacing the unit. It had a digital "signature" on it that just was the tech writing NA. I never actually signed anything. Nothing they sent me mentioned anything about late fees, but considering I was done with this company and couldn't get them on the phone reliably to pay I mailed a check. The check was never cashed, and I tried calling a couple times over the last year. Now almost a year later they email me telling me I have a years' worth of late fees because they never cashed the check. I finally was able to call during the day (not always easy for me). I got a person who again told me the person I needed had already left for the day. I told them if they wanted to be paid they needed to take the card over the phone right now. She agreed. Then told me the current balance. I refused to pay the late fees and told them I would authorize only the original balance. She put me on hold while she checked and then blind transferred me. The person answered like they had no idea who I was. I explained the situation again (very frustrating) and he knew exactly who I was and already had the information. He stated they have several ways to pay, except apparently those ways aren't check since I tried that. And none of the mailed "invoices" I received provide any payment information, terms and conditions, or anything but the current balance and how many days late it was. Just "Past Due - Please Remit" and an address along with a return envelope. But I had already tried that. This person claimed to be willing to take the payment, but when I rejected the late fees he claimed he needed to investigate and would get back to me. I told him I am not available during the day and he scoffed at me. I gave him one final chance to accept the payment without late fees right then or I was going to stop even attempting to pay as my life doesn't revolve around a waste of time diagnostic service with a technician that didn't know what they were doing. It shouldn't be this hard to pay them. The late fees should have never existed if they just cashed the check I sent or had ever provided me with payment instructions. other than "Please Remit", a return envelope, and an address. I will never use these people again. Everything with them is a clown show. Can't get straight answers, can't get things properly diagnosed. Can't get trained people. Can't even pay their bill. AVOID AT ALL COSTS!!!!
