OSI Comfort Specialists: Comfort You Can Count On!
See what a difference four generations of experience can make
Here in the New York City area, we’re used to seeing all kinds of businesses come and go. You discover a perfect date-night restaurant, only to find it replaced with a gastropub a few months later.And when it comes to heating oil and HVAC services, you’ve likely seen a bunch of those businesses disappear suddenly. Some of your neighbors have likely called their usual heating oil or HVAC company needing delivery or a no-heat emergency service call only to find the number disconnected.
This is where OSI Comfort Specialists stand head and shoulders above the competition here in Nassau County and Queens. We’ve been taking care of your neighbors since Morris Levi founded the company in Rockaway Beach in 1936.
Since then, everyone at OSI Comfort Specialists has been dedicated to upholding Morris’s work ethic and his belief that we are in business to be neighbors helping neighbors.
