"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."

"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."

"Went very good, came in first thing in the morning and cut out old system and by late afternoon my new system was piped up and running"

"The technicians were clean, professional and punctual and did the job as was planned."

"I have the Total Mechanical Systems Total Comfort plan. It is wonderful I purchased the Comfort Plan when we installed our HVAC System. This is a great service plan for a reasonable rate. You get check ups on your HVAC, electrical, and plumbing systems.,You also have access to repair services, electricians, and plumbers at a discounted rate. Great overall plan to maintain your home or condo. Recently I had my annual Furnace/HVAC check up. The technician, Marquez, was professional, knowledgeable, and pleasant. Marquez really knew his stuff and explained to me how my furnace works and what the telltale signs are that I might need repairs. Fortunately I have not needed any repairs thanks to their great maintenance plan!"

"Excellent work on new HVAC (A/C & Furnace) install. A little pricey, but worth the peace of mind."

"I had a furnace installed 20 years ago. Since then it has been serviced by four (4) well-known Oil companies. To my dismay, not one could figure out why my furnace would get DIRTY as often as it did. It even plugged up within a year. Cleaning after cleaning ($$$ spent). I became very frustrated. Based on a friends recommendation, I called Cromwell Energy. I was amazed at the professionalism of the entire team. When Lou and Rich assessed the furnace they referred to the manufacturer and was advised that the burner that was originally installed and since replaced by another company was not the correct one to begin with! They corrected the problem and I have been trouble-free since. Thanks guys. I wish more companies would provide this type of service. You've got my business and I have since referred them to other family members who are just as pleased as I am. Keep up the good work! Your loyal customer."
