"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!"

"It went very well. They were the first and only plumbers to respond to the project. It was just before the 4th of July and the appointment was made for Tuesday the 6th. I was called that morning by them to see if they could come earlier because they had finish the job before me. I said yes and they arrived 20 min ahead of time. First thing that was done was examining what I had purchased. When that was okay the old toilet was removed. The flange needed to be replaced. I had figured that since the toilet was very loose on the floor. We discussed options and possible problems with each step. I was quoted a range of cost above the quote of project. It seemed very reasonable. When it was done the low numbers of both quotes were used and I was charged $529 which word for me. All trash was removed and the area was left very clean. We were able to discuss next steps I was thinking of for that bathroom. I was giving some very good advice. Excellent work! I recommend them and I will used them again when they he time comes"

"Advanced Mechanical Services (AMS) went out of their way to get our new oil tank installed and the old one removed in the winter. We were experiencing issues with our old tank where our oil company could not fill the old tank. AMS worked closely with us to install the new tank quickly. They kept us in the loop and were on time on installation day. The installers were professional, kept us informed and did an excellent job. In addition, they cleaned up after themselves. We also use them for our annual furnace cleaning. They always do a great job and have come out on emergency calls a few times over the past 25 (or more) years. I highly recommend them."

"Juan was great to work with. He efficiently cleaned and serviced our Gas Boiler. He provided some education about the capability and also noted we had a great boiler that was maintaining strong water pressure and temperature. Great service. Price was appropriate for non-emergency level work! I would easily use them again."

"I had a furnace installed 20 years ago. Since then it has been serviced by four (4) well-known Oil companies. To my dismay, not one could figure out why my furnace would get DIRTY as often as it did. It even plugged up within a year. Cleaning after cleaning ($$$ spent). I became very frustrated. Based on a friends recommendation, I called Cromwell Energy. I was amazed at the professionalism of the entire team. When Lou and Rich assessed the furnace they referred to the manufacturer and was advised that the burner that was originally installed and since replaced by another company was not the correct one to begin with! They corrected the problem and I have been trouble-free since. Thanks guys. I wish more companies would provide this type of service. You've got my business and I have since referred them to other family members who are just as pleased as I am. Keep up the good work! Your loyal customer."

Install Boiler questions, answered by experts

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

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.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.
