"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."

"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

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.
