Best boiler installation pros near Manchester, 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!"

"Outstanding service and professional installation!!"

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

"Joe and his crew did an excellent job installing new boiler and indirect hot water system. I made the decision to convert to gas and replace my 21 year old oil fired boiler. Everything went along smoothly and professionally. Joe kept me informed every step of the process and job was completed on time. I would definitely recommend."

"Bertram was very professional and very careful with bringing in and taking out old and new boiler. When coming in and out layed cloth to protect flooring etc I highly recommend him. I was given several quotes in a timely manner and he was very honest and helpful in helping me to make my decision to have him install the bolier. Will recommend him to friends and family."

"Outstanding service. I called because my boiler was leaking and the after hours technician responded within 30 minutes of our call. Our coil plate and gasket were rotted and bolts had snapped and we decided that we would replace the boiler because ours was 16 years old. We spoke with the owner and sales manager the following morning and were told that they would be happy to replace the boiler if that is what we wanted to do but they felt our boiler could be repaired at a fraction of the cost and no where near the end of it's usable life. So we decided to go for the repair and they were right, it worked like a charm! So instead of a $9,000 boiler and indirect replacement, we spent $472 and my boiler was up and running the next day. We have used Advanced Mechanical Services for our conversion from oil to natural gas and for our air conditioning installation. They have always been very professional, courteous, prompt and their pricing has always been competitive. I would highly recommend them."

"Very professional installation. Was done in a timely fashion and the crew was very professional and clean. Huge difference in the comfort of our home now."

"HIGHLY recommend! needed a kitchen faucet replaced. sent in request on home advisor at 730am. got a call at 8am to confirm time table and also a rough quote for the work needed. got a call at 830 from Ed that he was coming in 30min. Work was completed perfectly in less time than quoted and price was under initial quotes which i appreciate. I had a quote from aiello at 7am for over $1000 more than this job. I bought my own faucet for this saving some money, but ultimately saved $1000 paid $220 for visit and work completed. ABSOLUTELY recommend Ed and this company for any needs."

"Joe went out of his way to ensure our heat was back on, this company really cares about its customers. Hard to find these days, Great Service!!"

"Did not seal the inside of the new vent. It took weeks to get the permit number from them to schedule the inspection."
