Make-up Air Systems

Balanced air for
commercial spaces.
Make-up air systems replace air exhausted by commercial kitchen hoods and industrial ventilation — maintaining pressure, comfort, and code compliance.
What Is a Make-Up Air System?

When commercial exhaust systems remove air from a building (kitchen hoods, industrial ventilation), that air must be replaced. Without make-up air:

Doors become hard to open (negative pressure)

Exhaust systems work inefficiently

Drafts and comfort issues occur

Energy costs increase

Code violations may result

Make-up air units bring in fresh outdoor air, condition it (heat or cool), and deliver it to the space — maintaining balanced pressure and comfort.

FAQs

Is make-up air required for my restaurant?

Yes. Ontario Building Code requires make-up air for commercial kitchen exhaust systems. We ensure your installation meets code requirements.

Can make-up air be heated?

Yes. Make-up air units can include heating (and sometimes cooling) to condition incoming air before it enters the space.

How do I know if my make-up air system is working properly?

Signs of problems include: doors hard to open/close, drafts near the kitchen, exhaust hood not capturing smoke effectively, or comfort complaints.
