Top 5 Signs Your Commercial Kitchen Hood Needs Cleaning

A well-functioning kitchen exhaust system is essential for maintaining a safe and efficient commercial kitchen. However, recognizing when your kitchen hood needs cleaning can be challenging, especially with a busy day-to-day operation. To help you determine when it’s time for professional hood cleaning, we’ve compiled a list of the top 5 signs that indicate your commercial kitchen hood needs attention.

  1. Grease Buildup

One of the most apparent signs that your commercial kitchen hood needs cleaning is visible grease buildup. When you inspect the hood, filters, and ductwork, you may notice a thick layer of grease and grime. This accumulation not only poses a fire hazard but also reduces the efficiency of your exhaust system. If you see grease buildup, it’s time to call a professional hood cleaning service to ensure your kitchen remains safe and compliant with local and national regulations.

  1. Unpleasant Odors

A properly functioning kitchen exhaust system should effectively remove cooking odors, smoke, and steam. However, if you notice lingering smells in your kitchen even after the exhaust system has been running for some time, this could indicate that your hood needs cleaning. Grease and grime buildup in the hood and ductwork can trap cooking odors, creating an unpleasant environment for your employees and customers. A thorough hood cleaning will help eliminate these odors and maintain a fresh and clean atmosphere in your kitchen.

  1. Reduced Airflow

If you observe a reduction in the airflow of your kitchen exhaust system, it may be time for a hood cleaning. Reduced airflow can result from clogged filters or grease accumulation in the ductwork, which can hinder the proper functioning of the exhaust fan. This can lead to poor air quality in the kitchen, causing discomfort for your staff and potentially affecting the quality of the food prepared. A professional hood cleaning service can restore your exhaust system’s airflow, ensuring a healthier and more efficient kitchen environment.

  1. Frequent Smoke or Steam in the Kitchen

An effective exhaust system should quickly remove smoke and steam generated during cooking. If you notice persistent smoke or steam in your kitchen, it could be a sign that your hood and ductwork are not functioning correctly. This issue may be due to grease buildup, clogged filters, or malfunctioning equipment. A thorough hood cleaning can help resolve this problem and improve the overall efficiency of your kitchen’s ventilation system.

  1. It’s Been a While Since Your Last Hood Cleaning

If you can’t remember the last time you had your kitchen hood cleaned, it’s probably overdue. The frequency of hood cleaning depends on the type of cooking equipment used and the volume of cooking. For example, high-volume cooking operations like 24-hour diners and fast-food restaurants may require monthly cleaning, while low-volume cooking operations like churches and seasonal businesses may only need annual cleaning. It’s essential to consult with a professional hood cleaning company to determine the appropriate cleaning schedule for your specific kitchen and ensure compliance with local regulations.


Regular hood cleaning is crucial for maintaining a safe, efficient, and healthy commercial kitchen environment. By recognizing the signs that your kitchen hood needs cleaning, you can proactively address potential issues and ensure your kitchen remains compliant with fire and health codes. If you notice any of the signs mentioned above, don’t hesitate to contact a professional hood cleaning service. They will help you maintain a safe and efficient kitchen, protecting your business and the well-being of your employees and customers.
