Best boiler installation pros near Ellington, CT

"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.

"I had a great experience with Alex and Tyler. WB Dickenson was on time and able to service my home right away. They also were able to order me special parts and installed them the same day they were delivered. I will be using this company in the future."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

"It got done, unfortunately required a full system replacement."

"I took off work. The technician arrived said they were not qualified to work on Combi-tankless boilers; though I had explained over the phone when making the appointment; the Combi boiler I had, and the code e352, that I couldn't maintain heat. The boiler shutting down, and I worked nights; so please don't arrive before noon. Upset, I bleed the system myself and refilled going by the Navien manuals I had. The code e352 was gone. The psi was lower, the boiler didn't shut off. But psi was still a little high above 30. Hurley and David could only reschedule for the next day 12Pm to 4PM. Getting up (sleeping in because I work nights) I had 3 phone calls from 9:30am on, Hurley and David saying they were unable to reach me. That additional frustration got ironed out. A technician was sent. His name is Macauley. He immediately knew I needed an expansion tank and replaced same. The price was high, but his professionalism and communication skills made all the difference. And the psi normal"

"The tech JohnP was very knowledgeable and was the to change the tank filter before performing the boiler cleaning & maintenance."

"Overall experience was professional and very good. Although it took some time to get details nailed down and to get the installation scheduled, once a date was set, the Combustion Mechanical Services team was well coordinated, efficient and worked as cleanly as could be expected considering the job. It should be noted that since our boiler failed in late spring, with no heating requirements we were clear that there was no real rush for the install and that we were flexible. If there is one area where there may be an opportunity for improvement, I would recommend that system head loss calculations for each installation be done routinely by CMS as the original pumps specified for the job could be considered marginal for our application. As a Mechanical Engineer, I would rather pay a little more up front for pumps that are well-suited for the job than risk having a pump fail early (at an inconvenient time) because it does not quite have the power needed to easily do the job. Overall an excellent job with which we are very satisfied. I would highly recommend Combustion Mechanical Services and especially Steve Cole to anyone interested in a high-quality professional job."

"Never received quote for the service. They contacted me ask for a picture of the old boiler which I sent but never was contacted by them again."

"Beacon did a great job at installing a new American standard air handler and compressor unit. My was past it’s life span. They kept the work area clean and quickly installed new unit. Huge difference in performance. Jason at front office helped me throughout process. Kevin and guys did nice job installing and educating me on new system. Everyone was very easy to work with. And extremely professional."
