Hood Control Repair & Design
A properly wired commercial kitchen hood system keeps your restaurant compliant, your staff safe, and your energy costs under control. EmergenServe designs, installs, and repairs hood control electrical systems for commercial kitchens throughout the Charleston area.
Kitchen Hood Electrical That Passes Inspection
Commercial kitchen hood systems involve more than plugging in a fan. The exhaust motor, make-up air unit, fire suppression interlock, gas valve shut-off, and demand ventilation controls all need to work together, and the electrical connections between them must satisfy both NEC and local fire codes. A single miswired interlock can fail a health department or fire marshal inspection and keep your doors closed.
EmergenServe has wired hood systems for barbecue joints on upper King Street, seafood restaurants on Shem Creek, fast-casual chains in Summerville, and institutional kitchens at local schools and hospitals. We understand the specific requirements for Ansul and Kidde shunt trip connections, gas valve interlocks, and the sequencing logic that ensures make-up air balances exhaust airflow.
When a hood control panel fails and a relay sticks, a VFD faults, or an interlock stops communicating, we diagnose the electrical issue quickly and source replacement components to get your kitchen back in service. We carry common relays, contactors, and sensors on our trucks to minimize your downtime.
Kitchen hood control electrical work in Charleston is critical for the hundreds of restaurants, catering operations, and institutional food service facilities that make the Lowcountry a culinary destination. Our licensed commercial electricians understand the specific code requirements that govern commercial kitchen exhaust systems, including NFPA 96 standards for ventilation control, IMC requirements for make-up air balance, and the fire marshal inspections that every Charleston restaurant must pass before opening. We install variable frequency drives (VFDs) that reduce exhaust fan energy consumption by up to 40% compared to single-speed motors, saving restaurant owners significant money on utility bills while maintaining proper kitchen ventilation. Our hood control wiring services include demand control ventilation (DCV) sensor installation that automatically adjusts exhaust fan speed based on cooking activity, preventing the energy waste of running fans at full speed during slow periods. For new restaurant buildouts and existing kitchen renovations across the Charleston metro area, EmergenServe provides the specialized commercial kitchen electrical expertise that ensures your hood system passes inspection and operates efficiently from day one.

Charleston Restaurant Hood Control Expertise
Charleston's restaurant scene runs on demanding commercial kitchens, and every one of them depends on a properly wired exhaust hood control panel. Our electricians install and service controls from Captive-Aire, Greenheck, Accurex, Halton, and Gaylord, the manufacturers most commonly specified by Lowcountry mechanical engineers and kitchen designers. We handle everything from a simple single-fan exhaust hood in a King Street coffee shop to a multi-zone Type I hood with variable-speed make-up air at a downtown hotel.
Hood control wiring is not a job for a general electrician unfamiliar with NFPA 96, the South Carolina Mechanical Code, and the specific factory wiring diagrams that vary between manufacturers. We read the panel schematics, terminate every conductor to factory specification, label every wire, and document the system so future service is straightforward. When the health inspector or fire marshal arrives, your hood control system is ready.
Shunt Trip, Gas Valve, and Fire Suppression Integration
When the Ansul or Pyro-Chem fire suppression system over your cooking line discharges, several things must happen automatically and simultaneously: the exhaust fan must continue running, the make-up air unit must shut down, gas to the cooking appliances must close via a solenoid valve, and the electrical breaker feeding the appliances under the hood must shunt trip. We wire all of this so it works the first time, every time.
- Shunt trip breaker installation and testing
- Gas solenoid valve power and reset wiring
- Micro-switch interface from suppression panel
- Audible and visual alarm circuit installation
- Annual functional testing and documentation
- Coordination with your fire suppression contractor
VFD and Demand Control Ventilation
Modern Charleston restaurants are switching to demand control ventilation (DCV) to slash energy costs. Instead of running exhaust fans at full speed all day, DCV systems use temperature and optical sensors in the hood to ramp fan speed up and down based on actual cooking activity. We install variable frequency drives (VFDs) for both exhaust and make-up air motors, wire the sensor harnesses, and program the controllers so your kitchen runs efficiently without sacrificing capture and containment.
Energy savings on a typical 8,000 CFM hood with DCV often exceed several thousand dollars per year in Charleston's long warm-weather season, where conditioned make-up air is expensive to produce. We coordinate with your HVAC contractor and Dominion Energy SC rebate programs whenever possible.
Frequently Asked Questions
Do you wire new restaurant hoods or just service existing ones?
Both. We handle new installations for restaurant build-outs across Charleston, Mount Pleasant, and the Lowcountry, and we service existing hood control panels of every major brand. We also troubleshoot intermittent fan, light, or fire suppression issues.
Can you handle the fire suppression interlock wiring?
Yes. We wire the shunt trip breaker, gas solenoid valve, alarm circuits, and any auxiliary contacts required by your fire suppression contractor and the local fire marshal. We coordinate the final inspection so everything passes together.
How quickly can you respond if a hood goes down mid-service?
EmergenServe provides 24/7 emergency commercial electrical service throughout the Charleston area. If your hood control panel fails during dinner service, call (843) 754-1671 and we will dispatch immediately.
