Quick answer
Restaurant HVAC in Miami covers dining room cooling, kitchen make-up air that replaces air pulled out by exhaust hoods, humidity control, and fast repair of rooftop and split systems. The most common problem is negative pressure: kitchen exhaust pulling more air out than the system brings in, which drags hot humid air through the doors.

Restaurants are some of the hardest spaces to cool in Miami. Cooking equipment adds heat, full dining rooms add heat and moisture, and doors open constantly. On top of that, kitchen exhaust hoods pull large volumes of air out of the building every minute they run.
That exhaust air has to be replaced. When make-up air is too low or not conditioned, the building goes negative: doors are hard to open, hot air rushes in around every gap, the kitchen is sweltering and the dining room never cools. It looks like an AC problem, but adding tonnage alone does not fix it.
We look at the whole balance: rooftop or split system capacity, the make-up air unit, the exhaust, and how they interact. Then we fix what is broken and recommend what will keep it working.
