Oilheat and natural gas sales and service ... heating ... cooling ... plumbing ... indoor air quality ... water purification ... alternative energy solutions ... and so much more.

If it concerns your home comfort, OSI Comfort Specialists can handle it. After all, we've built our company by providing "Comfort you can count on."

Our roots may lie in the past - we've been family owned and operated for four generations, but our eyes are focused clearly on the future. That's why we now deliver "green" home comfort solutions with solar and geothermal energy systems.

One thing that hasn't changed since Morris Levi founded the company in 1936 is the way we care for our customers. Our friends and neighbors from Long Island and the five boroughs rely on us for total comfort ... delivered. We have "real people" answering the phones 24/7, so we're always there when you need us, no ifs, ands or buts!

Whether you're already an OSI Comfort Specialists client, or thinking about joining our family of satisfied customers, look around the site now to see what's new - and visit often for special online promotions, and news about latest innovations in home comfort.
