My wife and I had used a competitor of OSI for many years (they will remain nameless) but we are glad that we made the switch and have now been a very satisfied customer of OSI for 17 years. When you depend on heat, hot water and air conditioning it is so important that you use a company that you can depend on. OSI converted our home to central a/c over 10 years ago and today replaced our home’s original (over 70 years old) boiler with a high efficiency unit and hot water heater. Mike came to my home and explained what I n... read more

Want to post about my recent experience from OSI. Woke up this morning at 7am with no heat in my house and no idea where to start. Having a new home and no contract with any oil providers I was nervous about where to begin. A co-worker had recommended the team at OSI to help and I couldn't be happier with the experience. Mike and his team were at the house and had explained to me the in and outs of my boiler and had me up and running by 9am. I would highly recommend OSI to anyone that is looking for a professional high... read more

I have a pretty complicated 3 year old TecMar radiant heating/cooling system, 12 zones w individual thermostats. I called 3 different plumbing companies in to evaluate why several zones were not heating & each one gave me a different reason for the problem with price tags ranging from $3,000-$6,000 to repair. I finally got a recommendation from my local hardware store to call Mike Levi from OSI. He determined it was a programming problem and was able to fix the entire system by reprogramming each thermostat. He was very me... read more

After Hurricane Sandy hit, my husband had a Generac stand by generator installed so we would never have to go through that kind of a mess again (4 1/2 feet of water in basement because sump pumps obviously cannot run without electricity). My husband was meticulous with maintaining the generator. Now that he is not here, I needed someone to change the oil in the unit and make sure it was up to par. I already had the oil as well as the oil filter, so I thought I was going to have a problem finding someone to actually do the... read more

Dear Rita We wanted to thank you for your quick response to our service call. We would be remiss if we did not mention your serviceman, Andrey. When we open the door and see him, we know we are in good hands. His calm approach and patience eases our stress. He is as knowledgeable as he is kind. Andrey is respectful and neat and always acts professionally. Once again, thank you for providing us with such attentive service. Sincerely, Norma & Bob Harwood

I wanted to share with you the wonderful experience I had with you .It was Jan 22 the night of the big snow storm. I returned from work at 4;30 to find that I had no heat! I called your office and they couldn't have been any nicer. Ray came to my house about 5:00 and fixed the problem. He also changed my filters and stayed to make sure the heat stayed on. He was so nice and I really appreciated his kindness and great work. Thank you to all of you!
