"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"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.

"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."

"I needed quick service on a 45 year old hot water boiler in a 1938 house I recently purchased. While I could get the pilot light lit, nothing I did could get the boiler to fire (water was circulating).
On Wednesday I contacted Pelletier Mechanical as Gary (the owner) had been out giving me estimates on the various repairs and modifications I wanted to make. While Gary was out of the office training (again), Laura his admin arranged for Bill to come out on Friday. She provided an estimated cost (right on) and a 2 hour window.
Bill showed up on time and after a brief discussion get right to work. Bill spent about 15 mins. systematically determining why the flame would not light. He discovered that there the gas was not making it to the main control valve. He reset the safety shut off valve and the problem was solved. He then checked all the radiators to make sure that hot water was making it through out the house. After we determined that the upstairs radiators were not getting hot, Bill checked the water pressure and determined that the pressure was insufficient to fill the upstairs radiators in "real time". He suggested that the culprit was the 45 year old water valve and pressure release valve which being cast iron tend to corrode and clog in time. He proposed a replacement solution and priced it out, and offered to pick up the parts and replace the valves that afternoon. I decided to wait a few weeks so I could consider replacing the entire boiler.
While we were waiting on the boiler to come up to heat, Bill and I walked through the basement looking at the existing plumbing, tracing the water flow path and discussing the possibility of replacing the hot water tank with a tankless unit. (The hot water run is about 60-65 feet from HW tank to kitchen, bathrooms, etc.) Bill, like Gary, is knowledgeable and informative.
I will have Pelletier Mechanical back to do more work on the house."

"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."
