"The Boilerman saved me on New Years Eve! I got in over my head with a valve installation on my water main and thought FOR SURE I was going to completely flood my basement. He reassured me that everything was going to be ok over the phone, arrived when promised, talked me off the ledge, and promptly fixed the problem I'd created and helped me install the valve as intended. I really appreciated his expertise, assurance, good nature, and humor. Highly recommend!"

"In October 2020, I had a gas leak and I did not even know it until I was doing annual maintenance. The first company that came out made me believe that it could not be repaired and did nothing to mitigate the issue. I thought I would have to figure out where I was going find about $10 to $20 K to replace my boilers. I could not afford that. I called Sync Mechanical for a second look. They gave me an honest diagnosis of the issue and told me where the gas leak was as well. They told me that it is repairable and laid out what my options if I wanted to do repairs or replace it and the cost as well. They talked to me about their financing options at the time. I really had options. This gave me peace of mind because the gas leak was much smaller than I was made to believe before, but Sync Mechanical took the leak seriously. They identified other parts of my boilers that needed to be replaced to avoid pipes bursting such as my expansion tanks and pressure relief valves. I agreed to get the repairs made. Sync Mechanical ordered the parts, kept me updated on the arrival time, and called me when they arrived so I can schedule a time. Sync Mechanical was also honest about their schedule when also responding to emergency calls of no hot water. I appreciated that because I was never left with false expectations. They were able to fit me into schedule even when it was very busy. It felt great going with a local professional company that were honest at every step of the way and large enough to handle multiple jobs in the Hudson Valley. I did not feel overlooked. I have been stood up by contractors twice before so it was really important to me that my time was not being wasted. The repairs were done within a day and all the old materials were disposed of by Sync Mechanical. I also received my invoice in the mail which made it easy for doing my taxes. Sync Mechanical helped me make an informed decision and also learn more about how my boilers work. I never felt like they were condescending and I appreciated their respect for family as well."

"Moved heavy boiler up difficult site. Installed in one day. Very professional and patient in detailed explanations of complex zoning issues. Prices are high in Dutchess Co. compared to other areas of NY. I generally think plumbers are a safer bet for a maintenance plan and longer lasting businesses than most HVAC companies."

"Joe responded right away and was on time for the quote and installation. The central AC was done in half a day and he and his partner cleaned up after the work was done. In addition, his cost beat Jeff Lowe's Plumbing and Heating cost by over $2,000 on a comparable unit. AC works great. No complaints."

Customers say: Quality work

"David Kappas was very responsive-- he called me on Monday and we set an appointment for Wednesday. Tuesday he called me to tsay that he would be arrive at 11am instead of 9am as he needed to finish up some work. He fixed my clogged faucet and installed a shut off valve in an effective, efficient, calm manner. I went over some other plumbing needs and he discussed each one in a sensible way. I'm planning to use him for the other plumbing projects and am awaiting his estimate."

"It was a wonderful. Dave and his crew came in removed the old equipment in one day and installed the new one. The work was completed in 2 days and that was only because my house being 75 years old modifications had to done. Dave then ran the new system to ensure it met our satisfaction. Dave is very meticulous and keeps his work area clean. When he left it was like no one had ever entered my home."

Install Boiler FAQs, answered by experts

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model.
