Restaurant HVAC: Kitchen Heat, Makeup Air & Comfort

Restaurant HVAC lives or dies on balance: powerful kitchen exhaust must be matched with makeup air, while the dining room stays cool and comfortable for guests. Get the balance wrong and you get a hot kitchen, doors that will not close, and a sticky dining room — especially in New Orleans humidity.

What does restaurant HVAC have to solve?

A restaurant has two HVAC worlds: a kitchen that exhausts huge volumes of hot air through the hood, and a dining room that must stay cool and dry for guests. The kitchen exhaust must be balanced by makeup air measured in CFM, or the whole building goes negative-pressure.

When should you design the kitchen and the room separately?

  • Design dining-room cooling for crowd load at peak seating, not empty square footage.
  • Size makeup air to the hood exhaust so the kitchen breathes and stays workable.
  • Control dining-room humidity so guests feel cool, not clammy, on a busy Saturday.

Failure modes in restaurant comfort

  • Exhaust without makeup air: doors slam or will not open, pilot lights struggle, comfort collapses.
  • Undersized dining cooling: a full room overwhelms an AC sized for the floor plan alone.
  • No humidity control: humid makeup air makes the room sticky even when it is cool.

Proof

New Orleans dining rooms pack people in, and the kitchens run hot year-round. The restaurants that stay comfortable are the ones whose exhaust, makeup air, and dining cooling were sized together with a real load calculation — not bolted on piecemeal.

Frequently Asked Questions

Why won't my restaurant doors close?
Almost always negative pressure: kitchen exhaust is removing more air than makeup air replaces. Adding or correcting makeup air fixes the door pull and improves comfort.
Why is my dining room hot when it's full?
Each guest adds heat. If cooling was sized for an empty room, a full house overwhelms it. We size dining-room cooling for peak occupancy.
How much makeup air does my kitchen need?
It depends on your hood exhaust CFM and local code. We measure exhaust and design makeup air to balance it, keeping the kitchen workable and the building neutral.
