Get matched with top boiler installation pros in Cromwell, 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!"

"Timely, accommodating, and professional. Highly recommend Mull Bros. 75 years in business says it all! Wonderful staff and installers!"

"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!!"

"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."

"Precise HVAC was wonderful. I actually was going to get more quotes but after working with their salesperson I decided to not even bother. They answered all my questions and made suggestions for things I didn't know about. I'm not even sure I care if I got a better quote or not. With Precise I know that they cross the t's and dotted the eyes and I don't have to worry about missing something."

"Technician arrived on time for appointment. Greg was wonderful!!!! Explained his process and patiently answered all my questions. Excited to have local business to maintain our boiler services."

"Excellent response time to no heat on an extremely cold day. Eventually replaced boiler & heating system; knowledge and craftsmanship best I've hired. Great value for the work and level of service provided. Highly recommend this company."

"The technicians were clean, professional and punctual and did the job as was planned."

"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."

"Did a good job once they sent the right tech out. Was a minor miscommunication with dispatch to start but they got it corrected and the technician was great. "
