I cannot speak more highly of Fong and Sullivan. I had a water leak that ended up being due to a…read moreclogged condenser in my HVAC/AC unit which was located on the roof. They already came highly recommended, but when I reached out, they were SO nice. They came out as quickly as they could (most companies told me 2-3 weeks!) but they called me several times to give me updates as to whether they could try to get to me even sooner than my scheduled appointment which was only 1 day after I called! Joe and Corey were truly amazing - firstly, they were incredibly communicative about their ETA. When they arrived, they did a thorough diagnosis of the HVAC unit and even took the time to explain exactly what they were doing and why. They took care of the issue with ease and made a lot of recommendations to prevent future damage. They also offered to look at some of the other AC parts and my AC filter just to make sure I was maintaining everything properly - a service they did not need to do or take more time for. They ended up staying just chatting about best practices and were just about the friendliest repair people I have ever dealt with. I own two properties and have been through SO many bad or iffy contractors and repair people so it's such a relief to find reliable and high quality service providers. I will use Fong and Sullivan every time I have an issue and cannot recommend Joe and Corey enough.

They are responsive and knowledgeable, taking the time to answer my questions and also giving me very practical advice on how I could save money going forward (even against their own interest). Their pricing is reasonable (and somewhat lower than most other HVAC companies I contacted when bidding out the work), and I have already recommended them to a neighbor who is looking for an honest assessment of some more serious HVAC issues.

I used Dempsey Energy about six years ago when we bought our home to evaluate our furnace. They…read morewere sent by American Home Shield. The furnace did need to be replaced, and they did great work. We paid about $3K for necessary modifications, which we expected since the furnace was already in rough condition. More recently, I had a leak in my basement from a burst pipe. I contacted Dempsey Energy and left a message requesting service for the next day. When I called the following morning, they scheduled a technician to arrive between 12-5. Mike came that afternoon and was very pleasant. He explained that our pipes should be replaced and showed me the difference between the old and new materials. He emailed an estimate for the work, and there was no pressure to proceed. I appreciate their honesty and professionalism. From the dispatch team to the technicians, everyone has been courteous and professional

Most recently, I lost my heating system 3-4 days before our first major winter storm this year. I had moved out of Mass. and into RI but called them anyway in hopes that they serviced my area. They were at my home that same day! I was given three different price and system options in their proposal. I was grateful to have a choice that could potentially fit my budget. Needless to say I was up and running again in time for the snowstorm! This is not the first time they were able to get me out of a jam. Briggs will always be my company. They have proven themselves over and over again with me. I would highly recommend them to anyone. Actually I did! My daughter is now a customer as well! Thank you Briggs! Nancy Gray

Our old unit was under warranty, but we still had to pay for labor. I asked over and over again for the paperwork for the new warranty that they never producted. The new unit was installed 2/1/25. In December of 2025 we had the same problem with the new unit! I called Briggs Mechanical. They sent out 2 different men, they weren't able to figure out the problem and told me they would have to contact the manufacturer and have them come out and look at the unit. I hsve left 2 messages and no one has every called me back. My thoughts are 1, they're waiting until 2/1/26 the year anniversary that they installed the unit and therefore I may not have a warranty or 2, they just don't have the knowledge to fix the problem. Bottom line .. stay away from Briggs Mechanical. Oh, and the owner Mike, he can talk the ears off a brass monkey with his BS.

However, as soon as you need a maintenance call you learn to why. They have a large staff and come right out when you have a problem. They can handle anything from routine work to replacing the entire boiler and have an excellent plumber on staff as well. They come by once a year for a tune up on the boiler. They monitor oil levels and auto deliver as needed. In 9 years, I have never come close to running out of oil or had to think about it. For everyone shopping solely on price, I recommend you consider how important service is, especially when you need an emergency call.
