Mahoney Heating LLC is a small heating-repair operation run by Mike Mahoney, working on oil burners and boilers for homeowners. All five reviews on file came in during one week this August, each describing the same kind of call: a heating system down and Mike getting it working again. One customer's oil burner kept kicking on and off; another had no hot water until Mike swapped a part on the boiler. Reviewers describe him as responsive, quick to diagnose the problem, and clear about what he did and why — one mentions he'd fixed their heat earlier in the winter at what they called an excellent price. There isn't much to go on yet — five reviews, all posted the same week this August, and no other source to compare against — so it doesn't yet cover a wide range of jobs. What's there is consistently positive on price, communication, and getting heat back on fast. For oil burner or boiler troubleshooting and repair, the reviews describe a responsive, detail-oriented technician homeowners would call again.
Mike is great! So nice and diligent in his work, great communication and very accommodating.
He fixed my heat back in the winter, and was excellently priced. He was great to communicate with and very detail oriented with his work. Mike was able to explain all the work he did, every step of the way. Would recommend!
Mahoney Heating LLC exceeded my expectations with their professionalism, knowledge, and attention to detail. From the initial communication through completion of the work, everything was handled efficiently and with a clear focus on quality. The work was done properly, the process was explained clearly, and they took the time to make sure everything was operating as it should. It’s refreshing to work with a company that takes pride in what they do and genuinely cares about providing excellent service. I would highly recommend Mahoney Heating LLC to anyone looking for a dependable, knowledgeable, and professional heating company. I wouldn’t hesitate to use them again for any future heating needs.
I had an issue with my oil burner kicking on and off. When I called Mahoney heating I was met with great customer service, response time and very knowledgeable tech when they came. Was very happy with the service as well as prices and now know who to call for all my oil heat needs. HIGHLY recommend Mahoney heating.
Michael came out and replaced a part on my boiler when I had no hot water. He is very responsive and can help diagnose issues quickly. Affordable pricing as well. Would recommend.
