"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!"

"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."

Install Boiler FAQs, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

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.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

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.
