"Bruce and Bill of Williams and Associates Mechanical Contracting recently removed and replaced my 18 year old oil fired boiler and added an indirect fired water heater. I had been saving for this project for over a year and had been geeking out in my avid research (Thanks Internet!) of products available, reviews and costs, as well as the reputation and reliability of local heating and plumbing contractors. I knew what I wanted, I just needed to stay within my budget and find a contractor I could trust. It is therefore, my pleasure to let others know, on the same web review sites that I referred to, how overwhelming pleased I am to have worked with Bruce Williams and his team. They skillfully removed and installed the heating system in a day, took pride in their work and took the time to explain the new system and to fully answer all my questions. Bruce and Bill clearly like what they do for a living, have great people skills and work very well together. I was able to get the very best of products and still come well under budget. I cannot thank these guys enough! Honest, Professional and Reliable! My dusty, unfinished basement with my new Viessmann boiler, Carlin burner and HTP indirect fired water heater is now my favorite part of the house!"

"Ocean State Air Solutions did a great job with our new Central Air Conditioning Unit installation. They came out in the spring to give us several different quotes for different types of air conditioning options, from wall units to central air with ventilation. They talked us through the pros and cons of the different systems and units. We decided to go with the Mitsubishi Electric unit with central air installation. The installation happened a few weeks later. The installation took 5 business days, and involved the installation of new ventilation in the attic with ducts in the ceiling. At the completion of the installation, Ocean State Air Solutions turned on the system and walked me through the operation of the system to ensure I understood how to operate. I recommend their services and would use again."

"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"

"Paul provided estimates for the 2 types of tanks I was interested in. Once tank type was decided on, a date for work was set. Paul and his team showed up on time and the job was completed in a timely manner. The quality of work and product are excellent. Work area was left completely clean. I am very pleased with the job done and would highly recommend New England Tank Service. Thanks again Paul!"

"Very well: the ducts were filled with dust, dirt, and construction debris and now they are clean and shown to be so with their air duct camera. The technician was friendly, professional, and knowledgable. I'd highly recommend hiring them right after buying a house, especially if it is new construction. Also, if you have new filters on hand, they will install them for you after they are done. They have transparent pricing, you can pay online in advance, and I received a discount for doing so in April."

"All three jobs went great. For the water heater replacement Lewis came to my house at a convenient time for me, removed the heater changed out the rotted pipes and installed a new one with warranty. The price was great too. This job was time sensitive and he made me a priority to get it done. For the bathroom tub drain unclog he was very professional and did a great job. My garbage disposal was leaking and I came home to a pool of water in my cabinet and on the floor. Lewis came out quickly to resolve the issue for me. He replaced everything under the sink and showed me what he was doing each step of the way. I think that he is a great plumber if you want to get quality work and learn about each job too."

Install Boiler FAQs, answered by experts

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

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. 

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.
