Commercial Kitchen Exhaust — Cold Freeze Technologies NJ

Type I vs. Type II kitchen exhaust hoods — what NJ code requires

Type I hoods are required over cooking equipment that produces grease-laden vapors: fryers, griddles, ranges, char-broilers. They require a grease duct, a listed exhaust fan, and fire suppression rough-in. Type II hoods handle heat and steam from equipment that doesn't produce grease vapors — ovens, steamers, dishwashers. NJ code follows NFPA 96. We file the correct permits, install to code, and coordinate with the fire suppression contractor for the suppression system inspection.

Makeup air — what it is and why it can't be skipped

A Type I exhaust fan pulling 2,000 CFM out of a kitchen has to get that air from somewhere. Without a makeup air unit, the replacement air comes from the dining room — pulling cold air in winter, creating pressure differentials that make doors hard to open, and defeating the hood's ability to capture grease vapors. Makeup air units supply tempered outside air directly into or near the hood. We size both the exhaust and the makeup air together.

Kitchen exhaust installation — from quote to final inspection

We start with a kitchen equipment list to size the CFM correctly. We pull the permits (mechanical, and potentially fire alarm depending on municipality). We install the hood, duct, and exhaust fan. We coordinate with the fire suppression contractor for the rough-in. Final inspection with your municipality. Most NJ restaurant kitchen exhaust installations run $8,000–$24,000 depending on hood size and duct run length.

"Most contractors do refrigeration OR HVAC. We do both — plus ductwork fabrication, kitchen exhaust, warehouse ventilation, and industrial-scale cooling. One call, one crew, one licensed contractor who stands behind the work."

Common questions about commercial kitchen exhaust

How much does commercial kitchen exhaust installation cost in NJ?

A typical restaurant hood + exhaust fan + makeup air installation: $8,000–$24,000 fully permitted and installed. Pizza shops with a single-deck oven at the lower end. Full-service restaurants with multiple cooking stations at the higher end. We give a fixed price after seeing the kitchen layout and equipment list.

Do you install fire suppression systems in kitchen hoods?

We coordinate and rough-in for fire suppression but don't install the suppression system itself — that requires a separate fire suppression contractor license. We manage the rough-in during our installation so the suppression contractor can complete their work cleanly.

What are NJ code requirements for commercial kitchen exhaust?

NJ follows NFPA 96, which specifies CFM ratings, duct materials (16-gauge minimum for Type I grease ducts), listed fans, and fire suppression requirements. Local municipalities add requirements on top of state code. We pull the right permits and install to the correct standard.

Can you replace or repair an existing kitchen exhaust system?

Yes — fan replacements, hood repair, makeup air unit replacement, and belt/bearing service on existing exhaust fans. If your existing system is undersized or non-code-compliant, we can scope a replacement or modification.
