Kitchen Ventilation & Make-Up Air in Glendale, CA
Glendale restaurants range from compact spaces along Brand to larger food-hall style operations near the Galleria. Hot weather makes air balance more noticeable, since a kitchen with poor make-up air becomes unbearable quickly. Davinci Mechanical reviews exhaust fan output, make-up air units, and space pressure together so the kitchen, dining room, and neighboring tenants are not fighting each other. Hood and duct cleaning stays with a separate contractor, since this is balance and ventilation work.

How kitchen ventilation & make-up air work plays out in Glendale
The complaint usually arrives in July. A restaurant on Brand Boulevard or Honolulu Avenue in Montrose calls because the cooking line is unbearable, the front door is hard to open, and the dining room feels like it is being pulled toward the kitchen. The hood runs, but it is not capturing; smoke rolls out at the edges. In most of these kitchens the exhaust fan was upgraded at some point and the make-up air never was, so the kitchen runs at negative pressure and drags conditioned air out of the dining room and hot outside air in through every gap. Glendale's heat makes the imbalance obvious in a way a cooler city would hide.
The buildings make it harder. Older storefronts along Brand and Glenoaks have shallow roofs shared with neighbors, limited wall area for intake louvers, and sometimes residential units above that constrain where a fan can sit. Food-court and restaurant-row tenants at the Galleria and Americana share building exhaust and make-up systems with landlord rules about what can be changed. The work is to measure what the hood is exhausting, what the make-up unit is actually delivering, and what the space pressure is doing, then correct the pieces that are off: fan speed, make-up unit operation, dampers, or interlocks.
A good result is a kitchen that holds a slight negative pressure relative to the dining room, a hood that captures, and a front door that opens normally, with the readings and settings recorded in the DaVinci Portal. This is air-side work; hood and duct grease cleaning is a separate trade and we say so up front. The kitchen ventilation and make-up air page and the restaurants industry page describe the common fixes.
Glendale's climate and what it does to this equipment
Glendale is warmer than the coast, with hot, dry summers shaped by its position against the Verdugo Mountains and the edge of the San Fernando Valley. Summer afternoons regularly reach the 90s, with heat waves that go higher, and nights offer less relief than coastal cities. Santa Ana winds bring dry air, dust, and fire-season smoke that clog filters and coils. Hillside and foothill conditions also deposit leaves and debris in outdoor equipment, and long cooling seasons make efficient airflow essential.

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 Glendale: questions we get
Our Montrose restaurant has no roof space left for a make-up air unit. What are the options?
Several, depending on the building. A sidewall intake with a tempered make-up unit, a smaller unit mounted on a rear wall or over a service alley, or a transfer-air approach from adjacent space can all work when the roof is full. We also look at whether the existing exhaust is oversized for the actual cooking line, because reducing excessive exhaust can bring the space back toward balance without any new equipment. The right answer comes from measuring first.
The landlord at our Galleria-area restaurant says the make-up air is a shared building system. Can we still fix our kitchen?
Usually yes, within the landlord's rules. Shared systems often have per-tenant dampers, interlocks, or fan controls that have drifted, and verifying the tenant side of the system is normally allowed. Where the fix requires a change to the building system, we document the measurements and the proposed change so the landlord's engineer can approve it. Having the numbers on paper tends to move that conversation quickly.
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.
