Replacing What Kitchen Exhaust Removes

Commercial kitchen exhaust hoods remove massive volumes of air—often 1,000+ CFM per hood. Without makeup air replacing what’s exhausted, your building fights negative pressure that affects everything from door operation to HVAC efficiency.

Unit Types for Commercial Kitchens

  • Direct-Fired Units – Most energy-efficient heating for large volumes.
  • Indirect-Fired Units – When exhaust products in airstream aren’t acceptable.
  • Electric Heat Options – For facilities without gas service.
  • Cooling Capable Systems – Summer comfort in hot kitchen environments.

Why Makeup Air is Non-Negotiable?

  • Code Compliance
    Most jurisdictions require makeup air when kitchen exhaust exceeds specific thresholds. We ensure your installation meets all mechanical code requirements.
  • Proper Exhaust Function
    Negative pressure restricts exhaust hood performance. Adequate makeup air lets your ventilation system work as designed.
  • Doors That Actually Work
    Extreme negative pressure makes entry doors nearly impossible to open. Makeup air eliminates this common restaurant frustration.
  • HVAC System Protection
    Without makeup air, your dining room HVAC works overtime pulling unconditioned outside air through every crack. Controlled makeup air reduces this waste dramatically.

We Works like our own

Installation Configurations

Adding makeup air to operating restaurants without disrupting business requires careful planning and execution. We coordinate installations around your schedule.

Rooftop Mounting

Most common for new construction and adequate roof access

Sidewall Applications

When roof space is limited or unavailable

Curb Adapters

Matching units to existing roof penetrations during replacement

Ductwork Distribution

Efficient delivery to kitchen areas needing makeup air

Common Kitchen Problems We Solve

  • Excessive Negative Pressure – Doors slamming, difficult entry, uncomfortable drafts
  • Cold Kitchen Environments – Unconditioned outside air infiltrating during winter
  • Hot Spots Near Cooking Lines – Inadequate makeup air allowing heat buildup
  • High Utility Bills – HVAC systems compensating for uncontrolled infiltration

Integration with Exhaust Systems

  • Interlock Controls – Makeup air automatically activates when kitchen exhaust runs
  • Proportional Response – Multiple speed operation matching exhaust volumes
  • Time Delays – Preventing pressure surges during startup and shutdown

Balancing Building Pressure

Proper makeup air doesn't just serve the kitchen—it affects the entire building. We design systems that maintain slight positive pressure in dining areas while adequately supplying kitchen zones.

Maintenance Access and Serviceability

Filters need changing, burners need cleaning, and controls require occasional adjustment. We install makeup air units with maintenance accessibility in mind.

Quick Service and Fast Casual Applications

High-volume quick service restaurants have unique makeup air demands. We understand the equipment densities and operational patterns these concepts require.
