Mainstream was founded 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 systems and equipment. Continuous, iterative product development, paired with a steady expansion of production capability and a strong culture of service, has Mainstream positioned for robust growth throughout the next decade.

We are focused on delivering expertly engineered solutions with unmatched speed and responsiveness.

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 principles that have propelled the growth of the business, and characterize what clients have come to expect from us.
