"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!"

"The Fellowship Team recently installed a new boiler system for me and the experience was flawless from start to finish. Replacing a primary heating system is a major investment, but this team made the entire process stress-free. The installation was incredibly clean. The technicians routed the new piping with surgical precision, ensuring everything was tidy, secure, and easy to access for future maintenance. Since the install, my home reaches the target temperature much faster than before, and the unit runs so quietly I barely notice it?s on. I?m already seeing the benefits in my lower monthly energy bills. The crew arrived on schedule, was sure to not damage anything, and clearly explained how to use the new digital thermostat before they left. They treated my home with genuine respect. It is rare to see this level of dedication to quality. If you need a reliable, high-performing heating system installed by pros who actually care about the details, look no further. Highly recommended"

"I had what I felt was an emergency situation. An outside water faucet was not closing and shutting off properly. Spewing water onto my patio area. Nick was here within an hour and not only fixed the problem but installed a new plumbing fixture that is amazing., I can work it without any discomfort with my old lady hands. There is also extra protection from freezing in the cold winter months. I will call him again and refer his company to all my friends."

"we had many problems with a burnham high efficiency system installed in 2009. We called NEBWs and Steve came down. He is very informative, courteous and attentive to our concerns. Within a week we had a new SlantFinn boiler installed and the installation was immaculate. Very neat and organized presentation. Experts in their fields, true professionals and reasonably priced. High recommend"

Install Boiler questions, answered by experts

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

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

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.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.
