"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."

"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."

"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!!!"

Install Boiler FAQs, answered by experts

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
