J Hanlon Oil Co is a Marlborough, MA business. A 2022 review says Johnny Hanlon has done this type of work for many years and his wife, Caroline, deals with billing. In 2023, a leaking oil tank was replaced. Johnny called back less than 5 minutes after a voicemail, showed up when he said he would and explained in detail what work would be done and when; he and his crew then showed up on time, completed the task and went through the preventative maintenance that can be done at home to keep the furnace running. In 2022, Hanlon Oil removed an in ground oil burner at a place of business in Lexington, and that review calls them timely, efficient, knowledgeable and personable. In a 2026 review, the person who picked up the phone hung up before a question could be asked, and kept hanging up on repeat calls.
The person who picked up the phone was very disrespectful, she just hung up the phone before I can ask her a question then I called back twice and she kept hanging up, when I called her with my other phone she picked up playing dumb like I didn’t know her voice . Next thing she’s laughing and she hung up again like huh . Employees like that our not good for business
Recently found myself in need of a replacement oil tank. The current one was leaking. Went on a couple of facebook pages for my city and saw John Hanlon's name more than once. So I gave a call, left a voicemail and less than 5 minutes later, Johnny called me back and set up a visit to come and see the situation. As my dad has always told me a minimum of three estimates, I attempted to scheduled a few others to come by. Two were bigger companies and one other was a local guy. The bigger companies were polite enough and they were prompt with appointment scheduling, the last was another local guy who acted like he didn't even know why I would call him for this. He promised to do some pricing and get back to me - still waiting on him...Johnny, showed up when he said he would, explained to me in detail what work would be done and when. No pressure whatsoever, but even before he left, I knew that I would be going with him. I did keep the additional appointments, so that my dad wouldn't yell at me :-). Johnny and his crew showed up on time and completed the task and then took me through the process of what had been done and preventative maintenance, I can do on my own to keep my furnace running to the best of its capability. If you are looking for a dependable, responsible, reliable and personable person to do work on your furnace or oil tank - call Johnny you won't be disappointed!
We contracted to have Hanlon Oil remove an in ground oil burner at our place of business in Lexington. Great decision! They were recommended to us by our insurance agent who had used them similarly and we couldn't have been more pleased. Johnny Hanlon has done this type of work for many years and he made it easy for us. They were timely, efficient, knowledgeable and personable. His wife, Caroline, deals with billing and she couldn't have been nicer. If five stars is as high as it goes, I'd give them six.
