"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"Bertram was very professional and very careful with bringing in and taking out old and new boiler. When coming in and out layed cloth to protect flooring etc I highly recommend him. I was given several quotes in a timely manner and he was very honest and helpful in helping me to make my decision to have him install the bolier. Will recommend him to friends and family."

"Outstanding service. I called because my boiler was leaking and the after hours technician responded within 30 minutes of our call. Our coil plate and gasket were rotted and bolts had snapped and we decided that we would replace the boiler because ours was 16 years old. We spoke with the owner and sales manager the following morning and were told that they would be happy to replace the boiler if that is what we wanted to do but they felt our boiler could be repaired at a fraction of the cost and no where near the end of it's usable life. So we decided to go for the repair and they were right, it worked like a charm! So instead of a $9,000 boiler and indirect replacement, we spent $472 and my boiler was up and running the next day. We have used Advanced Mechanical Services for our conversion from oil to natural gas and for our air conditioning installation. They have always been very professional, courteous, prompt and their pricing has always been competitive. I would highly recommend them."

"I received a phone call almost immediately after requesting service for my boiler. I was scheduled for the very next day, and the work that was done was done quite well. Greg, the service tech who came out, explained to me what he was doing as he was cleaning my boiler. I highly recommend using this company!"

"I really enjoyed having the work done by East Coast. They were professional, and when I had questions, they took the time to answer them, even if it meant calling in someone else, or coming by on another day to demonstrate some of the features of the system. In my book, East Coast goes above and beyond the contract to really provide customer satisfaction."

Install Boiler questions, answered by experts

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

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.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.
