"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!"

"John was outstanding! He meticulously diagnosed the problem and installed the equipment after tracking it down at 2 local supply houses. He kept us informed every step of the way and worked diligently until the work was completed. This is the second time we've asked Mull Bros. to perform a service at our house. We received excellent service both times. Mull Bros. is a highly professional company that has exceeded our expectations.

"Joe and Larry were wonderful! We bought a new house that needed work, including a serious issue with how our water heater was installed (without a pressure release valve!). Joe came by and looked at it all and because the situation was dangerous he and Larry came the very next day. Their estimate was clear and the job came in at the estimate (with one small additional nal.repair they found taking a part the toilet.). They walked me through everything and made me feel at ease. These are our new go-to plumbers!!"

"Jeremy came the evening of the day I called him accommodating my schedule. It wasn't even an emergency, at least I didn't think it was. I called for a cleaning but he immediately identified a problem I didn't know I had. He walked me through the diagnostic, described and demonstrated the problem, quoted the job and when I accepted it he performed the repair. When he left my boiler was working efficiently. The boiler was working but the heated water wasn't circulating through the baseboard. I was constantly burning oil with minimal effect. It had felt drafty in the house and I was relying largely on a gas fireplace to take the chill out of the air. That's no longer the case, the house is warm. He's coming to clean the boiler Wednesday evening. I will never hire anyone but Jeremy again to maintain my boiler."

"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."

Install Boiler questions, answered by experts

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

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.
