"Jonathan and his guys did excellent work for me in replacing my boiler. I had submitted several bids to different contractors and Jonathan gave me the best price. The guys that came to my house to install my new boiler and replace my old boiler were very professional and clean. I had two problems (a water leak and cold room) since the boiler was installed. I called Jonathan recently and he sent his guy right over and fixed both problems. I highly recommend his company. I would definitely use them again."

"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."

"David and his crew were great! They were very communicative on what the issue was and responsive to my questions and calls. I had a pipe dug out and replaced in my yard by then. Will definitely hire them again if anything else happens. Would highly recommend to anyone looking for work done correctly."

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."

"David did a wonderful job replacing my 31 yr. old oil fired boiler+water heater from start to finish.He designed a high efficiency system,removed the old system and replaced everything including valves and controls.He even installed a "HEAT MANAGER Module" to make it even more efficient! He also connected my new basement zone into the system. The workmanship is excellent! The price was VERY reasonable.He was a pleasure to work with and I HIGHLY RECOMMEND HIM!!!"

"They're okay. They're supposed to notify us when they put oil in but they don't always do that. That's not good but they're a good company. They come out two times a year. They're pretty professional."

Install Boiler FAQs, answered by experts

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.
