About Mainstream Fluid & Air

Engineered HVAC Equipment, Built Around Your Application

Mainstream Fluid & Air is a commercial and industrial HVAC equipment manufacturer and solutions provider, focused on fan arrays, air-moving equipment, replacement coils, cooling tower systems, and HVAC controls.

What We Do

Equipment for Commercial & Industrial HVAC Systems

We manufacture and sell commercial and industrial HVAC equipment and components, including custom fan arrays, ventilation and air-handling systems, replacement heating and cooling coils, cooling tower fan systems, and HVAC controls. Our focus is on engineered equipment that fits the specific requirements of each project, rather than one-size-fits-all products.

Many of the projects we support involve existing equipment: an aging air-handling unit that needs a new fan array, a coil bank that requires replacement, or a cooling tower that needs its fan system modernized. In each case, the equipment is developed around the dimensions, airflow, electrical, and control requirements of the application.

Our Approach

Solutions Developed Around the Application

Commercial and industrial HVAC equipment rarely fits a single standard configuration. We work from the specifics of each project — existing equipment dimensions, airflow and pressure requirements, access constraints, electrical considerations, and control needs — to help identify the right equipment for the application.

Understand the Application

We start by learning about your existing equipment, facility, and project goals.

Review Requirements

Dimensions, airflow, pressure, electrical, and control requirements inform the right equipment approach.
