Why Exhaust Hood Maintenance Matters
Neglecting your commercial exhaust hood system isn’t just an inconvenience — it’s a serious safety and compliance risk. Here’s why regular service is essential:
- Fire safety — Grease buildup in hoods and ductwork is one of the leading causes of commercial kitchen fires
- Health code compliance — Chicago and Illinois health inspectors check ventilation systems during routine inspections
- Indoor air quality — A properly functioning exhaust system removes smoke, heat, grease particles, and cooking odors
- Energy efficiency — A clean, well-maintained system operates more efficiently and reduces energy costs
- Equipment longevity — Regular maintenance extends the life of motors, fans, belts, and other components
- Insurance requirements — Many insurance policies require documented maintenance of kitchen ventilation systems

Frequently Asked Questions
How often should commercial exhaust hoods be cleaned?
NFPA 96 guidelines recommend cleaning frequency based on cooking volume: monthly for high-volume operations like 24-hour kitchens, quarterly for moderate-volume restaurants, semi-annually for moderate-volume kitchens, and annually for low-volume operations. HiTek can help you determine the right schedule for your kitchen.
Can you help us pass a health or fire inspection?
Yes. We can inspect your exhaust hood system, identify any issues, and perform the necessary repairs or maintenance to help ensure your kitchen passes health and fire inspections.
What is a makeup air unit and why does my kitchen need one?
A makeup air unit (MAU) replaces the air that your exhaust hood removes from the kitchen. Without adequate makeup air, you get negative pressure issues — doors that are hard to open, poor exhaust performance, and uncomfortable conditions for staff. Proper makeup air balance is required by code and essential for your system to work correctly.
Do you install new exhaust hood systems?
Yes. HiTek Mechanical handles new exhaust hood installation for restaurant build-outs, kitchen renovations, and equipment upgrades. We work with you to design and install a system that meets code requirements and fits your cooking operations.
How do I know if my exhaust fan motor needs replacement?
Common signs include the fan not turning on, running slowly, making grinding or squealing noises, or tripping the breaker. If your kitchen feels smoky or hot even with the hood running, the fan motor may be failing and should be inspected by a technician.
