Restaurant hood systems are critical for maintaining a safe, clean, and efficient kitchen. Designed to remove smoke, heat, grease, and odors, these systems protect staff, ensure regulatory compliance, and promote healthy air quality. However, as with any commercial kitchen equipment, hood systems can experience performance issues that compromise safety and efficiency. In this guide, we explore common hood system problems, offer practical solutions, and highlight the professional services available from Bestech—San Jose’s trusted provider for commercial restaurant appliance repair and maintenance.
Over time, grease accumulates in hoods, filters, and ductwork, reducing system efficiency and increasing fire risk. Regular cleaning is essential to prevent dangerous buildup and ensure compliance with fire safety codes.
Clogged filters, undersized systems, or blocked ducts can result in insufficient ventilation. This leads to a smoky kitchen, uncomfortable working conditions, and poor indoor air quality. Proper system sizing and routine maintenance are key to resolving ventilation issues.
Loud or unusual noises may be caused by worn-out fan bearings, loose components, or motor problems. Addressing the root cause of the noise improves comfort and extends the lifespan of the unit.
The fan is the core of any ventilation system. Electrical faults, motor wear, or physical obstructions can stop the fan from working, severely limiting the system's effectiveness.
Problems with wiring, control panels, or power supply can cause system failure or safety hazards. Immediate inspection and repair are crucial to maintain safe operations.
Look for signs of wear, loose components, grease buildup, or damaged filters. Inspect fan motors, ducts, and panels for any visible signs of malfunction.
Grinding or rattling noises could indicate mechanical wear, while hissing sounds might point to airflow leaks. Identifying the sound source can help narrow down the issue.
If your system struggles to remove heat and smoke, airflow may be compromised. Poor airflow can signal a clogged filter, fan issue, or duct blockage. An airflow meter can help measure performance.

Clean filters, ducts, and hood interiors regularly using approved degreasers. Schedule professional deep cleaning quarterly or according to usage.
Check components like motors, fans, and electrical systems every few months. Professional inspections should be conducted at least once per year.
Always operate the system during cooking and follow manufacturer usage guidelines. Avoid overloading the system beyond its rated capacity.
1. Why won’t my hood system turn on?
Check for tripped breakers, motor issues, or control panel errors. Inspect the power source and consult error codes if available.
2. How often should my system be serviced?
Cleaning schedules depend on usage. Monthly for solid fuel, quarterly for high-volume, and semi-annually for moderate use. Grease trays should be emptied at least monthly.
3. What causes loud operation?
Noises may indicate failing motors, worn belts, or loose components. Tighten, clean, or replace parts as needed.
4. Why is water leaking from the hood?
Condensation buildup or clogged drains can cause leaks. Improve ventilation and inspect the drainage system.
5. What causes poor ventilation?
Clogged filters, blocked ducts, or a faulty fan can restrict airflow. Clean or replace affected components.
6. How can I increase system efficiency?
Clean regularly, inspect airflow, and upgrade outdated parts with energy-efficient replacements.
7. Why isn’t smoke being properly extracted?
An undersized hood, dirty filters, or failing fan may be to blame. Assess each component and replace as needed.
8. What if my hood isn’t up to code?
Schedule an inspection to ensure NFPA 96 compliance. Upgrade suppression systems and ventilation as required.
9. How do I prevent grease buildup?
Clean filters frequently, degrease interior surfaces, and follow a consistent cleaning schedule.
