(SERVICE OVERVIEW)

Professional Exhaust Fan Installation Services

An efficient exhaust system relies on a properly sized and correctly installed exhaust fan. In commercial kitchens, code dictates the use of upblast exhaust fans that discharge grease vapors vertically away from the roof surface. These fans must be mounted on a secure roof curb and equipped with a safety hinge kit.

Whether you are building a new commercial kitchen, upgrading your ventilation system, or replacing an old, inefficient fan, Crossaire delivers turnkey installation services. Our technicians verify airflow requirements, size the fan to your kitchen's cooking volume, install mounting equipment, and ensure full fire code compliance.

(CRITICAL HYGIENE & SAFETY)

Why Professional Installation is Essential

Installing a commercial exhaust fan requires specialized knowledge of structural curbs, electrical systems, and fire codes. Here is why you should trust certified professionals:

Code-Approved Upblast Fans

Building codes require exhaust fans to discharge grease upward and away from the roof. We install approved upblast fans that meet all safety standards.

Safety Hinge Kit Setup

NFPA 96 requires exhaust fans to be hinged to allow cleaning and maintenance without damaging the fan base or roof surface. We install heavy-duty hinge kits.

Rooftop Leak Prevention

Exhaust fans must be mounted on a flashed, weather-tight roof curb. Professional installation ensures a leak-free seal that protects your building.

(SYSTEM WARNING SIGNS)

When to Replace Your Exhaust Fan

Consider replacing your existing rooftop fan if you notice any of these persistent signs of wear or failure:

Frequent Motor Breakdowns

If you are replacing motors or capacitors multiple times a year, the fan housing is likely worn out.

Severe Casing Corrosion

Rusted or warped fan housing causes air leaks, vibration, and dangerous grease leakage onto the roof.

Excessive Vibration Noise

Structural damage inside the fan assembly causes permanent wobbling, shaking, and noise in the dining room.

Outgrown Kitchen Capacity

If you add fryers or charbroilers, your current fan may lack the CFM capacity to pull the increased smoke.

Old, High-Energy Fan

Replacing a legacy belt-drive fan with a modern direct-drive ECM fan significantly reduces monthly energy costs.

No Safety Hinge Installed

Fans lacking hinge kits cannot be legally cleaned, prompting inspectors to demand system retrofits.

(HOW WE WORK)

Our Step-by-Step Process

We employ a meticulous, structured process to ensure safety, efficiency, and zero mess left behind:

CFM Airflow Calculation

We evaluate your hood length, appliance type, and duct layout to determine the required CFM and static pressure.

Curb Preparation

We construct the roof curb over the duct opening, ensuring a liquid-tight seal with flashing and roofing cement.

Hinge Kit Retrofitting

We pre-install a heavy-duty hinge kit onto the curb base to allow the exhaust fan to tilt back safely.

Exhaust Fan Positioning

The new upblast fan is hoisted to the roof and secured to the hinged curb framework.

Grease Drain Drainpipe

We install a grease drainpipe and rooftop grease collection box to catch grease runoff before it hits the roof.

Electrical Wiring

We wire the motor to the disconnect switch, verifying correct rotation direction and voltage connections.

Airflow Balancing

We test the fan operation, verifying that the make-up air system balances correctly and the hood draws strong suction.

Frequently Asked Questions

Got questions about Kitchen Exhaust Fan Installation schedules, compliance, or logistics? Find detailed answers below:

If your fan housing is rusted through, the fan wheel is warped, the unit shakes violently due to structural damage, or the fan motor fails repeatedly, replacement is the more cost-effective option. Upgrading also ensures compliance with modern codes.

An upblast fan is a roof-mounted unit that discharges air vertically. A utility set is a larger, belt-driven fan housed in a protective cabinet, typically used for long duct runs or high-static pressure requirements, and can be mounted on the ground or roof.

NFPA 96 mandates hinge kits. Without them, cleaners must lift the heavy fan off the duct opening to clean the ductwork, which can damage the fan housing, pinch electrical wires, or tear the roof membrane. Hinging allows the fan to swing open safely.

Exhaust fans are sized based on CFM (Cubic Feet per Minute) requirements, which are calculated using the hood's length and the type of cooking equipment (light-duty vs. heavy-duty charbroiling). Static pressure of the duct run is also factored in.

A typical fan replacement takes 3 to 6 hours. Installing a new curb and running new ductwork can extend this timeframe. We schedule our work to minimize kitchen downtime.

Yes. Our technicians mount and connect the fan to the local rooftop disconnect switch, verify motor rotation, and ensure the electrical system meets local safety codes.
