Mainstream - Custom HVAC Solutions


Mainstream's involvement with custom air handling systems allows us to offer a full range of components for retrofit or repair of built-up air handling units. Mainstream's components can be manufactured to fit through the tightest openings and spaces, minimizing rigging requirements without compromising performance.

Downtime is kept to a minimum and units can be re-built in phases during off-hours without service disruption because components are designed to easily integrate with existing systems. Save 40% or more over new air handling units by replacing only the components necessary to improve your air handler's performance while preventing costly shut-downs or interruptions to production.

Expedited production cycles are available on almost all components, and in some cases, lead time can be reduced to a matter of days. The following are products that Mainstream sells:
