"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!"

"Mull Brothers gave us an estimate on installation of central air conditioner in our old home. Their price was slightly higher than some competitors (although not by very much), so we didn't end up using them. However, I was very impressed with Mr. Mull's visit. He was knowledgeable and thorough, and gave me great information without using any high-pressure sales tactics. I will probably contact them again in the future for my next project.

"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."

"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."

"From start to finish with my project Gary and his team were helpful, responsive, knowledgeable, and professional. Gary considered all of my heating/ac/humidity concerns, took full measurements of my condo, system and energy calculations, and recommended three good options of Bryant electric split heat pump systems. I ended up choosing the most efficient top of the line model as I was replacing a 25+ year old unit. I felt that the price was fair and even if I could have found a slightly lower price, I was very comfortable hiring Pelletier based on Gary’s initial follow-up, professionalism and thoroughness when quoting my job. They also went the extra mile when doing the installation under terrible weather conditions. I’m very pleased with the end result. I have no hesitation in recommending Pelletier."

"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."
