In Summerville, SC, where the local food scene is thriving and restaurants line Main Street and Highway 78, commercial kitchens work hard day in and day out. Reliable exhaust systems are essential not only for comfort but for safety and code compliance.
This week, our team at Arctic Air Inc. completed a full rooftop grill exhaust replacement for a busy restaurant in Summerville. The result was a cleaner, safer, and more efficient ventilation system designed to handle daily heavy use in the Lowcountry’s humid climate.
How We Properly Replaced a Restaurant Exhaust System
Here’s how our team completed a safe, code-compliant replacement using proven commercial methods.
Removing the Old and Preparing for the New
The unit was fully removed and the curb exposed. Years of grease buildup and corrosion were clearly visible. That kind of wear is common in South Carolina kitchens, where humidity accelerates metal degradation and grease saturation.
After removing the old unit, we thoroughly cleaned the base and inspected the structural integrity of the roof penetration.
Inspecting and Reinforcing the Curb
We closely checked the existing curb for rust or weakness. Any compromised metal was reinforced to guarantee a secure mounting point. Proper alignment and sealing are key here.
A flush, stable base ensures the fan can operate efficiently without vibration, air leaks, or exposure to the elements.
Crane Lift for Safe Installation
Once the site was prepped, we used a crane to safely lift the new upblast exhaust fan onto the roof.
Our crew guided the unit into place with precision. This step is typical for commercial-grade exhaust fans, which are too large to move manually and must be carefully positioned to avoid damage to the roof structure or the fan itself.
Final Hook-Up and Testing
With the new fan in position, our technicians secured it, reconnected the electrical lines, and completed startup testing. We checked airflow performance, motor function, balance, and duct connections.
Everything was verified to meet current code requirements and safety standards. The result is a robust, energy-efficient exhaust system that can handle the demands of a high-output kitchen.
This upgrade not only improves airflow and kitchen comfort but also lowers fire risk and reduces future maintenance issues.
The restaurant now has peace of mind knowing their exhaust system meets the demands of their operation, plus the regulations of the local fire and health departments.
