How to Choose the Right Exhaust Hood for Your Restaurant (Without Overbuying)

Choosing the right commercial kitchen exhaust hood is one of the most important decisions you’ll make when building or upgrading a commercial kitchen. The right system helps keep your kitchen safe, comfortable, and code-compliant, while the wrong one can lead to wasted money, failed inspections, or costly changes later.

This guide walks through how to select the right exhaust hood for your restaurant without overspending or overcomplicating the process.

 

Start With Your Cooking Equipment

The type of food you cook determines the type of hood you need.

  • Grease-producing equipment such as fryers, grills, and ranges typically requires a Type 1 hood.
  • Heat or steam-only equipment such as ovens, steamers, and dishwashers typically requires a Type 2 hood.

If even one appliance produces grease, you’ll need a Type 1 hood. This is where many buyers accidentally underbuy, or overspend later by upgrading unnecessarily.

Hood Size Matters, But Bigger Isn’t Always Better

Exhaust hoods should extend beyond the cooking equipment to provide proper capture and coverage.

  • 6 inches past the equipment on each side
  • 12 inches beyond the front edge

Buying an oversized hood may seem safer, but it can:

  • Increase exhaust airflow requirements
  • Raise makeup air costs
  • Add unnecessary installation complexity

The goal is proper coverage, not excess size.

Right-sizing a commercial exhaust hood means matching all three main factors — hood type, hood design, and exhaust rate — to the actual demands of the cooking equipment. Overbuying on CFM increases equipment cost, raises energy consumption, and requires a larger makeup air system to compensate. Underbuying creates capture failures, grease buildup, and inspection problems. A properly specified hood delivers the performance the kitchen needs without unnecessary overhead.

Understand What’s Included in a Commercial Hood System

A complete exhaust hood system often includes:

Understanding these components upfront helps prevent surprise costs later.

Do You Need Makeup Air?

In most cases, yes. Makeup air replaces the air removed by your exhaust hood. Without it, your kitchen can experience:

  • Negative pressure
  • Poor hood performance
  • Increased HVAC strain

Most local codes require makeup air for commercial kitchens.

Ventless Hoods: When They Make Sense

Ventless hoods can be a great option when:

  • Equipment is electric
  • UL 710B requirements are met
  • Roof access is limited

They’re popular in food trucks, ghost kitchens, and leased spaces, but they’re not a universal solution.

Avoid Common Buying Mistakes

Common issues include:

  • Choosing the wrong hood type
  • Underestimating airflow needs and CFM rating
  • Forgetting fire suppression requirements
  • Not planning for code inspections

Working with knowledgeable suppliers helps avoid these pitfalls.
