Air Ducts & Kitchen Hoods Cleaning

Air ducts are the channels that carry cool or warm air inside buildings, and they are a vital part of central air conditioning systems. Over time, these ducts accumulate dust and dirt, affecting air quality and reducing the efficiency of the HVAC system. Over time, air ducts can contain a variety of contaminants, such as dust, mold, bacteria, pollen, and even dead insects. In certain environments, such as restaurants and factories, oils and smoke may also accumulate inside the ducts, making cleaning more complex.

Air ducts are cleaned using advanced techniques such as high-pressure air vacuums, rotating brushes, and fog-based disinfection devices. In some cases, robots equipped with small cameras are used to reach tight areas inside the ducts.

A kitchen hood consists of several parts, including metal filters that absorb grease, carbon filters that reduce odors, the fan that pulls air, and ventilation pipes that carry fumes outside. Due to daily cooking, grease and oils accumulate inside the hood and filters, leading to clogging and reducing suction efficiency. If the hood is not cleaned regularly, it may become a source of unpleasant odors, and grease buildup increases the risk of kitchen fires.

Kitchen hoods are cleaned using grease-dissolving products, and the metal filters are disassembled and soaked in hot soapy water to remove accumulated grease. The internal fan and ventilation pipes are also cleaned to ensure smooth airflow.

Benefits of a regular air ducts and kitchen hoods cleaning

Cleaning of air ducts and hoods is essential for maintaining air conditioning efficiency and indoor air quality. Over time, dust, grease, dirt, mold, and bacteria accumulate inside these ducts and hoods, potentially causing health issues and reduced system performance. If you're experiencing weak cooling, high electricity bills, or respiratory issues, the main cause may be clogged or contaminated air ducts.

When should you clean your air ducts and hoods ?

Every 6-12 months for regular maintenance and optimal cooling.
Every 3-6 months if you live in a dusty area.
If you notice musty odors or increased allergies.

After construction or renovation work, as dust and chemicals can settle inside the ducts.

Risks of neglecting kitchens hoods & air ducts cleaning

Declining indoor air quality

Accumulated dust and contaminants release harmful particles into the air, causing allergies and respiratory problems.

Increased electricity bills

The more pollutants inside the system, the more effort it requires to function, resulting in higher energy costs.

Reduced cooling efficiency

Clogged ducts force the air conditioning system to work harder, leading to higher energy consumption.

Pest infestation

Air ducts can become a breeding ground for pests and rodents, adding further hygiene concerns.

How is the kitchens hoods & air ducts cleaning done?

Inspection and Assessment

Before cleaning begins, a detailed inspection is conducted using specialized cameras, checking:

The level of dust and dirt accumulation inside the ducts.
Any leaks affecting system efficiency.
Signs of mold or bacteria growth.

Dust and Contaminant Removal

High-powered vacuum machines remove built-up dust and debris.
All vents and fans are cleaned to prevent airflow blockages.

Air filters are emptied and cleaned to maintain fresh airflow.

Disinfection and Sanitization

Safe, non-toxic disinfectants are used to eliminate germs and bacteria.

UV-C light technology can be applied to sterilize the air and prevent microbial growth.

Final Performance Testing

Airflow is tested to ensure clean and unobstructed circulation.

The process of air system cleaning

1. Air Ducts Cleaning
2. Kitchens and Restaurant Hoods Cleaning

Cleaning air ducts is an advanced process that requires specialized equipment and professional techniques to effectively remove dirt and contaminants. Here are the key steps that our professional team follow to clean air ducts:

Our technicians begin by inspecting the entire HVAC system, including ducts, filters, fans, and heat exchangers, to determine the level of dust and debris buildup. Inspection cameras are used internally to reach deep areas inside the ducts.
A high-powered industrial vacuum is connected to the ducts to create negative pressure, preventing airborne particles from spreading during cleaning. This process helps suction dust and debris directly from the ducts.
Then, specialized cleaning tools are inserted into the ductwork, such as rotating brushes to dislodge stuck dirt, compressed air systems to push out debris from corners, and disinfectant solutions (if necessary) to eliminate mold and bacteria.
Additional system components are cleaned to ensure optimal performance, including coils and fans to improve airflow, drain pan to prevent water blockages, and air registers and vents to remove accumulated dirt.
After cleaning, a final inspection is conducted to ensure all contaminants are removed. Air quality measurement devices are used to verify improved ventilation and reduced pollutants.

Cleaning a kitchen hood is essential for maintaining ventilation efficiency, reducing fire hazards, and improving air quality in both commercial and residential kitchens. Our expert technical team performs the following professional kitchen hood cleaning technique:

The team will start with disconnecting the power source to the exhaust system for safety during cleaning then covering nearby appliances to protect them from falling grease and dirt. Filters, fans, and any detachable parts are to be removed to facilitate deep cleaning.
Secondly, industrial degreasers will be sprayed on the interior and exterior surfaces of the hood, allowing the cleaner to sit for a few minutes to break down stubborn grease deposits. The team will use heavy-duty brushes or scrapers to remove stuck-on grease.
Filters will be soaked in a hot water and degreaser solution to dissolve grease buildup and then a stiff brush or abrasive sponge will be used to scrub the filters and remove dirt.
After cleaning, all parts will be rinsed with hot water to remove any detergent residue. Filters and fans should dry completely before reinstallation to prevent moisture buildup and mold growth.
Filters and fans will be reinstalled, ensuring they are securely in place. The team will turn on the hood to verify that it operates efficiently without blockages or unusual noises.

Why is cleaning kitchen ducts and hoods important?

Kitchen ducts are ventilation systems designed to remove smoke, steam, grease, and odors from the cooking area. These ducts are connected to kitchen hoods, which are the large ventilating units located above cooking equipment (such as stoves, ovens, and fryers). The hoods capture and filter the contaminated air, which is then expelled through the ductwork.

Cleaning kitchen ducts and hoods is essential for maintaining a clean, safe, and healthy environment in restaurants and commercial kitchens. Over time, grease, dust, and food particles can accumulate inside these systems, creating fire hazards, health risks, and reducing the overall efficiency of the ventilation system. Regular cleaning of exhaust systems ensures optimal performance, prevents potential fire accidents, and promotes better air quality in the kitchen.

Fire Prevention

Grease buildup inside kitchen ducts and hoods is one of the leading causes of fires in commercial kitchens. When exposed to high temperatures, grease can ignite, causing dangerous fires. Regular cleaning reduces this risk significantly.

Improved Air Quality

Unclean hoods and ducts can lead to poor air circulation, causing unpleasant odors, smoke, and fumes to linger. Cleaning ensures fresher air and promotes a healthier environment for kitchen staff and customers.

Preventing Pest Breeding

Grease and food buildup in ducts and hoods provide an ideal environment for pests such as ants, cockroaches, and termites to breed. The accumulated grease serves as a rich food source for these pests, helping them thrive and spread. Regular cleaning of the kitchen ducts removes these organic materials, reducing the chances of pest infestation.

In addition, food remnants and grease in ventilation systems emit odors that attract pests. These smells can lure insects like flies and cockroaches. Regular cleaning reduces these unpleasant odors, making the kitchen environment less attractive to pests.

Compliance with Health and Safety Regulations

Restaurants are required by law to maintain proper ventilation systems. Failure to clean ducts and hoods regularly may lead to violations and penalties. Keeping your system clean ensures compliance with health and fire safety standards.
