"Bruce and Bill of Williams and Associates Mechanical Contracting recently removed and replaced my 18 year old oil fired boiler and added an indirect fired water heater. I had been saving for this project for over a year and had been geeking out in my avid research (Thanks Internet!) of products available, reviews and costs, as well as the reputation and reliability of local heating and plumbing contractors. I knew what I wanted, I just needed to stay within my budget and find a contractor I could trust. It is therefore, my pleasure to let others know, on the same web review sites that I referred to, how overwhelming pleased I am to have worked with Bruce Williams and his team. They skillfully removed and installed the heating system in a day, took pride in their work and took the time to explain the new system and to fully answer all my questions. Bruce and Bill clearly like what they do for a living, have great people skills and work very well together. I was able to get the very best of products and still come well under budget. I cannot thank these guys enough! Honest, Professional and Reliable! My dusty, unfinished basement with my new Viessmann boiler, Carlin burner and HTP indirect fired water heater is now my favorite part of the house!"

"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."

"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."

"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."

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