Commercial HVAC
Repair and maintenance for restaurant and kitchen ventilation systems that need stable airflow, tempered air, and reliable balance.
When doors are hard to open, cold air pours in, or exhaust overwhelms the space, we look at balance first.
We diagnose ignition faults, burner lockouts, gas heat problems, and MAUs that blow cold when they should temper air.
Poor replacement air affects hood performance, staff comfort, and day-to-day operation in busy commercial kitchens.
Kitchen Pressure Off?
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
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.
Common Symptoms
Kitchen feels cold, smoky, or hard to keep comfortable
Door slam, drafts, or obvious negative pressure in the building
MAU fan runs but heat does not come on
Burner lights inconsistently or locks out
Hood exhaust performance drops during busy service
Airflow sounds wrong or the unit vibrates excessively
MAU FAQs
A make-up air unit replaces the air removed by kitchen exhaust and ventilation systems so the building stays balanced, safe, and comfortable.
Yes. Bad MAU performance can create cold drafts, pressure problems, poor hood capture, and uncomfortable conditions for both staff and guests.
Yes. We service common direct-fired and tempered-air MAU setups used in commercial kitchens and food-service operations.
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.
