"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."

"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

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

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.

Most installations take 2-5 days, including old system removal and setup.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.
