Exhaust and Ventilation / 01
Document symptoms safely
Record the type of unusual noise (such as vibration, rubbing, or humming), when it occurs, how long the equipment has been running, and any changes in smoke or odor. For multiple stores, recording the store name, equipment location, and symptoms using the same fields makes it easier to compare the circumstances.
Do not touch fans, belts, blades, or electrical components while they are operating. Leave inspections that involve opening covers, operating power controls, or entering rooftops or ceiling spaces to the store manager and qualified professionals.
- Details of unusual noise, vibration, or odors
- When it occurs and the operating conditions
- Areas with weak suction
- Filter cleaning date and recent maintenance history

Distinguishing Cleaning from Equipment Repairs
Clogged filters and grease buildup can affect exhaust, but cleaning does not necessarily resolve unusual noise or restore airflow. Other possible causes may require inspection or repair, including the motor, belt, bearings, a blocked duct, or insufficient air supply.
If unusual noise suddenly becomes louder, you smell something burning, there is strong vibration, or equipment stops, do not continue operating it by force. Follow the store’s emergency procedures and contact the person in charge or facility manager.
- Clogged filter
- We check the exterior using the store's procedures, along with cleaning records and replacement timing.
- Unusual Noise or Vibration
- Record when it occurs and any changes in sound, then discuss whether the fan needs inspection or repair.
- Reduced suction
- Record the location, time, and cooking conditions, and check both air supply and exhaust.

Information to provide and costs to confirm
Please provide the store location, fan location, model number if known, symptoms, how often they occur, and any past cleaning or repair history. Preliminary surveys and work conditions may vary depending on whether work at height or on a rooftop, opening an access panel, or inspecting electrical or mechanical components is required.
Specify whether you need cleaning, inspection, or repairs, and confirm what is included in the estimate and under what conditions additional costs, such as parts replacement, may apply.
FAQ / QUESTIONS
Frequently Asked Questions
Can cleaning fix unusual exhaust fan noise?
Dirt may be a contributing factor, but there may also be causes unrelated to cleaning, such as worn or faulty parts. Record the type of noise and when it occurs, then consult a specialist to determine whether cleaning, inspection, or repair is needed.
Can I open the fan myself to inspect it?
Do not touch moving parts, electrical components, or equipment in high places while it is operating. Follow the store's safety procedures when opening or closing covers or operating power controls, and consult the person in charge and qualified professionals.
The information presented is general guidance to help organize the conditions at your store. We will advise on whether work can be carried out, the method, and the cost after confirming the equipment specifications, contract, region, and on-site conditions. In an emergency or if there is a hazard, follow the store’s official safety and hygiene procedures and the facility manager’s instructions first.
