Mainstream began in the early 90’s as a family business in north Jersey, manufacturing coils and other HVAC components. Over the past two and a half decades, Mainstream has grown and evolved into one of the leading manufacturers of air handling equipment on the east coast, and as our capabilities have expanded, we have come to be known as one of the most agile, creative solutions providers in the industry.

Our mission here at Mainstream is to become our clients’ most trusted supplier by delivering expertly engineered solutions faster than anyone else.

We aim to become a leader in the market for engineered fluid and air equipment. We believe we can do this by understanding both our customers’ needs and the principles that apply to those needs better than anyone else, and providing innovative solutions to those problems.

Mainstream’s core values of knowledge, innovation and integrity are the guiding principles that have been fundamental to the growth of the business, and characterize what our clients have come to expect from us.
