"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."

"Joe and Larry were wonderful! We bought a new house that needed work, including a serious issue with how our water heater was installed (without a pressure release valve!). Joe came by and looked at it all and because the situation was dangerous he and Larry came the very next day. Their estimate was clear and the job came in at the estimate (with one small additional nal.repair they found taking a part the toilet.). They walked me through everything and made me feel at ease. These are our new go-to plumbers!!"

"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.

"Tom and his team went out of their way to help me with what turned out to be an emergency, with the potential of a dangerous situation with my furnace. They located a replacement unit and installed it the same day. Additionally, Tom is working with the manufacturer for me on a warranty issue as the unit replaced was only 7 years old I would recommend Omni highly and appreciate all the effort they extended to me."
