Commercial Exhaust Fan Service

NFPA 96 requires safe access to the exhaust duct for inspection and cleaning. A hinge kit allows the fan to tilt open on its base, giving technicians direct access to the ductwork below without removing the fan entirely. Without a hinge kit, the fan must be lifted off — which is a safety hazard, slows down service, and can damage the roof membrane or the fan itself. Most fire marshals and insurance companies expect hinge kits to be installed.

Common signs include unusual vibration or noise, reduced airflow in the kitchen (smoke not clearing the hood efficiently), visible grease buildup on the fan or rooftop discharge, a belt that squeals or slips, or a fan that runs hot. Any of these can indicate worn bearings, a stretched belt, motor issues, or excessive grease loading. Addressing these early prevents costly failures and keeps your system in compliance.

We perform minor repairs on-site — belt replacement, bearing lubrication, hinge kit installation, and grease removal. If a fan needs major repair or full replacement, we document the condition with photos and provide a clear recommendation so you can get the right solution. We do not upsell replacement when a repair will restore proper function.

Yes. Every fan service includes a photo-documented report covering motor condition, belt and bearing status, airflow performance, hinge-kit compliance, and any repairs performed. This documentation is produced by PECT Designated technicians and is routinely accepted by fire marshals, landlords, and insurance companies.
