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 methodical and determined to make sure it was running perfectly and easy for me to make inividual room changes. While he was working on the system he also found that the original installer had not put the Weil Mclain burner in to code, it was unsafe and he reinstalled it properly. Mike is extremely proffessional, knows his stuff, is proud of his work and goes out of his way to be as helpful as possible. On top of that he always wears a smile~I can't praise Mike & OSI enough!

My family and I have been using these guys on multiple properties for half a decade and pretty much no problems. Never came close to running out of oil. Pricing was good. Always diligent on maintenance and always professional staff from billing to their techs.

Had OSI for oil delivery service. Their driver overfilled my oil tank. Landed up with oil in the basement and outside in the soil. Driver left and never reported it. They never notified and my family came home to smell the oil. I had to call the DEC to get OSI to do anything about it.
