Why Proper Fresh Make-Up Air Units Are Essential in Commercial Kitchens

Why Proper Fresh Make-Up Air Units Are Essential in Commercial Kitchens — and Why A&M Heating and Air Conditioning is the Right Choice

In a commercial kitchen, air quality isn’t just about comfort — it’s about safety, performance, and compliance. Properly installed fresh make-up air (MUA) units are critical to maintaining a balanced environment where exhaust hoods, cooking equipment, and staff can all function efficiently. Without them, you risk negative air pressure, poor ventilation, excessive heat, and the buildup of smoke and contaminants — all of which can violate code and compromise the health of your team and customers.

Make-Up Air Units: The Unsung Hero of the Kitchen

When powerful exhaust systems remove smoke, grease, and odors from a kitchen, they also pull out large volumes of indoor air. A make-up air unit replaces that lost air with fresh, tempered air from outside — preventing dangerous pressure imbalances that can cause doors to slam, hoods to fail, pilot lights to blow out, or carbon monoxide to backdraft into the space.

Without proper MUA, your HVAC system works overtime, energy costs rise, and indoor air quality suffers. That’s why commercial kitchens are required by code in most jurisdictions to have functioning and properly sized MUA units in place.
