"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.

"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."

"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."

"Pete, Jake and Jeremy and a couple of other workers from Cool Heat Mechanical did a great job on installing 3 central air conditioners and air handlers at my house over a 3 day period. They were neat, clean, on-time and did an excellent job installing the American Standard A/C and air handlers. The units are running great and improved my energy efficiency tremendously over my older units. Pete is extremely knowledgeable with his profession of installing A/C and heating systems. His pricing is excellent as well. We are also using them to install a new heating system within the next few weeks. We initially met with Dave who reviewed their products and gave us the pricing for the job. Dave made an excellent presentation of all their products and did not use any high pressure selling tactics. He offered some nice financing options through EnergizeCT that I was not aware of as well. I did have multiple vendors competing for the job and found that Cool Heat Mechanical was the most knowledgeable and had the best products and pricing in my area. I did a fair amount of research and this company is the one to use for your heating and cooling needs. I highly recommend Cool Heat Mechanical for your HVAC requirements."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."
