Kitchen Ventilation & Make-Up Air in Burbank, CA
Magnolia Park restaurants often occupy older buildings with kitchens added or altered over time. In valley heat, poor make-up air makes the cooking line unbearable and drags conditioned air from the dining room. Davinci Mechanical looks at exhaust fan output, make-up air operation, and space pressure together, adjusting or repairing the pieces that are off. Scrubbing hoods and ductwork is a different specialty from the air balance and ventilation work described here. Magnolia Boulevard kitchens often need a creative solution because roof space and wall openings are limited.

How kitchen ventilation & make-up air work plays out in Burbank
Walk down Magnolia Boulevard on a hot evening and the symptoms are visible from the sidewalk: a front door propped open because it is too hard to pull, a dining room that feels drafty, cooks working in a kitchen that is ten degrees hotter than it should be. The cause is almost always the same. The exhaust hood was upgraded for a bigger cooking line at some point, the make-up air never kept pace, and the kitchen now runs deeply negative, pulling conditioned air out of the dining room and hot outside air in through every gap. Burbank's heat turns a balance problem into an operations problem.
The buildings fight back. Magnolia Park storefronts have shallow, shared roofs with little room for a make-up air unit, limited wall area for intake louvers, and alleys that are already crowded with condensing units. Studio commissaries have heavy cooking lines inside buildings that were designed for other uses, and the make-up air competes with the building's general ventilation. Hotel kitchens near the airport share systems with ballrooms and lobbies. The work is to measure what the hood exhausts, what the make-up unit actually delivers, and the resulting space pressure, then correct fan speed, make-up unit operation, dampers, and interlocks.
The target is a kitchen slightly negative to the dining room, a hood that captures, and a door that opens normally, with the readings and settings recorded in the DaVinci Portal. This is airflow and balance work, not hood or duct grease cleaning, and we say so at the start so expectations are clear. The kitchen ventilation page and the restaurants industry page describe the usual fixes for small-footprint kitchens.
Burbank's climate and what it does to this equipment
Burbank sits in the San Fernando Valley, and the valley holds heat. Summer days regularly reach the upper 90s and into the 100s during heat waves, with warm nights that limit equipment recovery. The marine layer that cools coastal cities rarely reaches this far, so cooling seasons are long and intense. Santa Ana winds add dry air, dust, and fire-season smoke that load filters and coils. In these conditions, rooftop condensers and chillers work close to their limits more often than elsewhere in the county.

What a kitchen ventilation & make-up air visit includes, and the problems we most often find
- Walk the kitchen during or near service to see what the building actually does
- Measure exhaust and make-up airflow, temperatures, and building pressure
- Inspect fans, belts, motors, dampers, burners, and controls
- Repair or adjust, then re-measure to confirm the balance
- Document results and flag items for the hood-cleaning and fire-protection vendors to handle
- Make-up air that is undersized or off, pulling conditioned air from the dining room
- Exhaust fan belts and bearings worn, cutting airflow below what the hood needs
- Kitchens running negative, causing hard-to-open doors, drafts, and burner issues
- Make-up air units with failed burners or controls during cold or hot weather
Kitchen Ventilation & Make-Up Air in Burbank: questions we get
Our Magnolia Park kitchen has no roof or wall space left for a make-up air unit. Are we stuck?
Rarely. The first step is to check whether the exhaust is running faster than the hood actually needs, because many were set at full speed by default and reducing excess exhaust can restore balance with no new equipment. If more make-up air is genuinely needed, options include a compact tempered unit on a rear wall, a sidewall intake with a smaller fan, or a transfer-air path from adjacent space. We measure first and propose the least invasive option that holds the numbers.
Our hotel kitchen near the airport makes the lobby drafty when the line is cooking. Is that a kitchen problem or a building problem?
Both, and they have to be solved together. A hotel kitchen hood pulling more air than its make-up unit supplies draws air from the nearest big volume, which is often the lobby or ballroom corridor, and the building's general air handler then fights to keep up. We measure kitchen exhaust, make-up supply, and the pressure relationship to adjacent spaces, then correct the kitchen side first. If the building air handler also needs rebalancing afterward, we document exactly what changed so the building engineer can follow.
Do you clean hoods and ducts?
No. Hood and duct cleaning is a separate specialty. We handle the mechanical side: exhaust fans, make-up air, and HVAC balance.
Why is my dining room hot when the kitchen is running?
Often the make-up air is not matched to the exhaust, so the kitchen pulls conditioned air from the dining room. Measuring airflow and pressure shows where the balance is off.
Can you replace a make-up air unit?
Yes. We size to the hood's exhaust requirement, coordinate permits, and handle rigging and controls.
