Exhaust Fan Services & Maintenance

Fan inspection, cleaning, and upkeep

A starved or unbalanced fan reduces capture at the hood and lets smoke and heat linger on the line. We clean fan blades and housings, check belts and bearings, and review rooftop grease containment.

Routine fan service extends equipment life and supports the NFPA 96 system clean you already schedule for the hood and ducts.

Upblast fans on restaurant roofs collect grease that can drip onto the roof membrane. Containment and cleaning protect both ventilation performance and the building envelope.

• Upblast and inline fan cleaning
• Belt and bearing checks
• Rooftop grease containment review
• Recommendations when repair or replacement is safer than another clean

Part of a complete exhaust program

Fan work pairs with hood and duct cleaning so the whole system moves air and stays documentation-ready. Ask for a free evaluation if you are unsure whether the fan, ducts, or hood is the bottleneck.

Operators across Raleigh-Durham-Chapel Hill often combine fan service with a hood clean on the same after-hours visit to reduce rooftop trips and keep documentation in one packet.

Signs your fan needs attention

Excessive vibration, belt squeal, weak capture at the hood, or grease pooling under the fan curb are common triggers for service.

We will tell you when cleaning is enough and when a worn bearing or warped wheel needs a different trade—so you are not paying for cleans that cannot restore performance.
