"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"

"Removed and disposed of old cast iron baseboard in kitchen (to make way for sliding patio doors) then supplied and installed copper piping & fittings to re-connect remaining baseboard. Chris and team always do a good clean job and I like the ease of doing business."

"John and his team are gems! A 15 year old tank went on Father?s Day weekend and John jumped in with excellent customer care! Limped the tank along for use till a new larger more efficient tank could be installed a few days later. No more cold showers for this busy family of 6! Thanks as always John!"

"I noticed my hot water heater was leaking so I called Modern Mechanical. They got here the same day, removed my old water heater and installed a new one! They even took the time to show me how to setup the app on my phone so I can monitor it. I truly always receive the best service from Modern Mechanical, never disappointed!"

"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"

"Very professional and efficient. The work was completed within a week of first contacting them and the job was finished within two hours of them arriving at our house. They were straight forward and honest about the work that actually needed to be performed and the final cost was less than what had been originally estimated over the phone. They cleaned up well and the finished installation looks excellent and is free of defects. I highly recommend this company."

Install Boiler FAQs, answered by experts

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.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

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. 

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.
