Why rebuild air handlers?

Greater Accessibility
Mainstream’s components can be manufactured to fit through the tightest openings and spaces, minimizing rigging requirements without compromising performance.

Minimal Downtime
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.

Cost Saving
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

Short Lead Time
Expedited production cycles are available on almost all components, and in some cases, lead time can be reduced to a matter of days.

Designing New Life into Your Old Air Handler In many cases, an existing air handler can be retrofitted with new components to achieve longer life and better performance at a much lower cost than total unit replacement. As a manufacture of Custom Air Handling Systems focused heavily on the retrofit and replacement market, Mainstream is able to offer design assistance, quality components, and technical support throughout the retrofit process.
