Exhaust Fan and Hood Repair for Orange County Kitchens
An exhaust system that can’t be cleaned properly, or a fan that stops mid-service, is a compliance problem and a business problem at the same time. Kitchen Guard of Orange County repairs and upgrades commercial kitchen exhaust systems: the fans, belts, motors, access panels, hinge kits and grease containment that keep a system safe, cleanable and running. Our crews already work inside these systems every week for hood cleaning, so we know what inspectors look for and what fails first.
Restaurant Exhaust Fan and Hood Repairs We Handle
- Access panel installation. Flat and curved panels for ductwork. NFPA 96 requires enough openings to clean the entire duct. Without them, sections of your system can’t be reached, and every cleaning report will say so.
- Exhaust fan replacement. Upblast and utility-set fans, sized to your hood and duct so the system pulls the air it was designed for.
- Belt and motor service. Belt adjustments and replacements, and motor replacement when a motor runs outside manufacturer specifications. Worn belts and struggling motors are the most common cause of weak draw and smoke rolling into the kitchen.
- Hinge kit installation. A hinge kit lets an upblast fan tip open safely for cleaning and service. Without one, the fan has to be unbolted and lifted, which risks damage to the fan, the curb and the roof.
- Grease containment. A separate item from the hinge kit. Containment catches the grease a rooftop fan throws off, so it doesn’t pool on the roof, damage roofing materials or run down your walls.
- Curb modifications. Adapting or raising fan curbs so replacement fans and hinge kits fit and seal correctly.
- NFPA 96 and fire code corrections. Fixing the items an inspector or your cleaning report flagged, so you can close them out.
Every repair uses UL-listed parts that meet manufacturer specifications and California codes.
Inspection Write-Ups We Fix Most Often
Whether your kitchen is inspected by the Orange County Fire Authority or a city fire department such as Anaheim, Huntington Beach or Newport Beach, the same items tend to come up:
- Duct sections that can’t be reached because access panels are missing or blocked
- Rooftop fans with no hinge kit, which makes a complete cleaning impractical
- Grease on the roof around the fan, a sign that containment is missing or full
- Exhaust fans that are noisy, underperforming or not running at all
- Damaged or missing hood filters. Our Filter Exchange program keeps a correct, undamaged set in place.
If your kitchen has been flagged, send us the report or call us. Many of these items have to be fixed before your next hood cleaning can be completed.
How a Repair Visit Works
- Assess the system. We inspect the hood, ductwork and rooftop fan, and review any inspection report or deficiency notes you have.
- Quote with photos. You get a photo-documented repair quote, so you can see the problem and what we recommend before any work starts.
- Repair. We install parts that meet manufacturer specifications and California codes, and test the fan once the work is done.
- Document it. You get a record of the work to show your inspector, landlord or insurer.
Exhaust Fan Maintenance Program
Most exhaust fan failures give warning signs long before they stop: a belt that’s glazing, bearings that run dry, a motor drawing more current than it should. Our Fan Maintenance Program catches those on a schedule for $110 per fan per month (price may vary by location).
- Quarterly visits by trained technicians
- Lubrication of the Zerk fittings on motors and bearings
- Motor casing cleaning to improve heat dissipation
- Fan belt replacement as needed, and at least every six months
- AMP draw measurement to confirm the motor is operating within manufacturer specifications
If a motor is running outside specifications, we schedule its replacement as a planned repair under warranty, before it fails on a Friday night. Motors, belts and bearings carry a lifetime warranty, effective after 30 days in the program, covering both parts and labor. If a replacement motor costs more than $400, you pay only the difference. Most motors cost between $300 and $400.

Repairs, Cleaning and Filters Work Together

Our hood cleaning crews note missing access panels, fans without hinge kits, failing grease containment and worn belts in every service report, with photos. That means you hear about a problem while it’s still a scheduled repair and not an emergency. Pairing repairs with regular hood cleaning and Filter Exchange keeps the whole system cleanable, compliant and running.
We serve restaurants, hotels, schools, hospitals and corporate kitchens across Orange County, from Brea and Fullerton to Anaheim, Santa Ana, Irvine, Costa Mesa, Huntington Beach, Newport Beach, Mission Viejo and San Clemente. Schedule a consultation or call (949) 445-1300.

A hinge kit lets an upblast fan tip open safely so the fan and the duct below it can be cleaned and serviced. Without one, the fan has to be unbolted and lifted off the curb, which risks damaging the fan, the curb and the roof, and often means the fan doesn’t get cleaned properly.
Grease containment catches the grease a rooftop exhaust fan throws off, so it doesn’t pool on the roof, damage roofing materials or run down your walls. It’s a separate item from the hinge kit. Most rooftop fans on commercial kitchens need both.
NFPA 96 requires enough access openings to clean the entire exhaust duct. Without them, sections of the duct can’t be reached, grease builds up where no one can see it, and every cleaning report has to note the areas that couldn’t be cleaned. We install flat and curved access panels to close those gaps.
We use UL-listed parts that meet manufacturer specifications and California codes. Replacement fans are sized to your hood and duct so the system pulls the air it was designed for.
Yes, and we’ll tell you up front. We focus on the exhaust system: fans, motors, belts, access panels, hinge kits, curbs and grease containment. If a problem is outside that, such as your fire suppression system or electrical service, we’ll point you to a qualified contractor.
