An oil burner cycling on and off and a boiler leaving a customer without hot water are two problems customers describe bringing to Mahoney Heating LLC. In an August 2026 Google review, one customer says Michael replaced a boiler part when they had no hot water, praising his responsiveness, diagnostic speed and affordable pricing. Another describes an oil-burner problem and praises the response time, the technician’s knowledge and the price. Explaining the work matters to these customers, too. A reviewer writing in August 2026 says Mike fixed their heat during the winter and explained each step of the work; they also praise his communication and attention to detail. Another customer says the company explained the process clearly and checked that everything operated as it should after the work. Google lists a 5-star average from six ratings.
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!

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.
