Commercial HVAC
Make-Up Air Unit Service Calgary
Repair and maintenance for restaurant and kitchen ventilation systems that need stable airflow, tempered air, and reliable balance.
Negative Pressure Problems
When doors are hard to open, cold air pours in, or exhaust overwhelms the space, we look at balance first.
Burner and Heat Issues
We diagnose ignition faults, burner lockouts, gas heat problems, and MAUs that blow cold when they should temper air.
Kitchen Comfort and Air Quality
Poor replacement air affects hood performance, staff comfort, and day-to-day operation in busy commercial kitchens.
Kitchen Pressure Off?
Fix the Air Balance Before the Whole Kitchen Feels It.
MAU problems affect hood performance, drafts, staff comfort, and combustion safety. We work through the replacement-air side so the rest of the kitchen can operate normally.

What We Work On
Service for the Kitchen Air Side, Not Just Comfort Complaints
When make-up air falls behind, restaurants feel it fast. Hood capture drops, cold air sneaks in through entrances, burners can misbehave, and the kitchen becomes a harder place to work.
We troubleshoot the MAU itself, the airflow relationship with exhaust, and the controls that should keep the whole system balanced during service.

Door slam, drafts, or obvious negative pressure in the building

MAU FAQs
Common Questions About Make-Up Air Service
What does a make-up air unit actually do?+
A make-up air unit replaces the air removed by kitchen exhaust and ventilation systems so the building stays balanced, safe, and comfortable.
Can poor make-up air cause restaurant comfort problems?+
Yes. Bad MAU performance can create cold drafts, pressure problems, poor hood capture, and uncomfortable conditions for both staff and guests.
Do you work on direct-fired make-up air units?+
Yes. We service common direct-fired and tempered-air MAU setups used in commercial kitchens and food-service operations.
Can you help if our kitchen has negative pressure?+
Yes. Negative pressure is one of the main reasons we get called for MAU service. We inspect the make-up air side, the exhaust side, and the control relationship between them.
