Best boiler installation pros near Wolcott, CT

"Yes, one day install conversion from tank electric to tankless gas with water softener"

"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. 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."

"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!!"

"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."

"Perfect as I expected and more. East Coast installed a central air system and a ductless heating and calling system in my house. They were much affordable than their competitor."

"I worked with several contractors to identify the best solution and price for my new boiler/tankless water heater. Chad was patient and thorough in his explanation of my options and costs. He installed a high efficiency system in 2015 that has worked flawlessly. We NEVER run out of hot water. The space in the basement has been cleared with the elimination of the old boiler and stand alone hot water heater and best of all.... my propane gas usage is 1/3 the amount it has been in previous years. Chad did a beautiful job on the installation. His work is meticulous and I've often told my friends/neighbors it is a work of art. He also helped me with the rebates and finance options available. I could not have asked for a better contractor. Chad was responsive, on time and left my house better than he found it. He removed the old equipment and even helped me by installing a new double filtration system for my well which he configured much better than the previous single filter. Based on this install and level of service, I would give Chad the highest possible recommendation."

"Very positive experience. They responded immediately when I sent the request. The gentleman who called asked me questions about my current setup and had a technician out promptly. The quote was reasonable and the job was completed in one day. Staff were friendly. Happy customer!"
