Air ducts are an important part of the ventilation and air conditioning system, which has the function of bringing fresh air from the outside to the inside and exhaust air to the outside. After a period of use, the air ducts will be covered with dust, bacteria, mold, etc. This will reduce the efficiency of the system, affecting the air quality in the house.
Therefore, periodic cleaning of air ducts is necessary to ensure that the ventilation and air conditioning system operates effectively, providing fresh air and protecting the health of users.
Benefits of duct cleaning
Regular cleaning of air ducts brings the following benefits:
- Cleans dirt, bacteria, mold, etc. to keep the air fresh and cool.
- Reduce the risk of respiratory and dermatological diseases, etc.
- Helps ventilation and air conditioning systems operate efficiently and save energy.
- Increase the life of ventilation and air conditioning systems.
Time needed to clean the air duct
The frequency of duct cleaning depends on many factors, including:
- Frequency of use of ventilation and air conditioning systems: If the system is used frequently, more frequent cleaning is required.
- Environmental conditions: If the environment around the system is dusty or polluted, it needs to be cleaned more frequently.
- Type of duct: Ducts with complex structures and difficult to clean need to be cleaned more often.
Normally, air ducts should be cleaned periodically every 6 months or once a year.
Air duct cleaning methods
There are two main methods of duct cleaning:
1. Cleaning the air duct manually: This method uses manual tools such as brooms, brushes, towels, etc. to clean dirt, bacteria, and mold on the surface of the air duct. This method has the advantage of being simple and easy to perform, but is not very effective and cannot clean dirt in hard-to-reach places.
Below are the steps to clean the air duct manually:
- Turn off ventilation and air conditioning.
- Disconnect power to the system.
- Remove the dust filters from the blower and suction inlets.
- Use a broom or brush to sweep away dust and dirt on the surface of the air duct.
- Use a damp cloth to wipe away dust and dirt from the surface of the air duct.
- Reinstall the dust filters.
- Turn on the ventilation and air conditioning system.
2. Cleaning air ducts by mechanical method: This method uses specialized equipment such as air blowers, vacuum cleaners, water sprayers, etc. to clean dust, bacteria, and mold on the surface of the air duct. This method has the advantage of being highly effective and can clean dust in hard-to-reach places, but the cost is higher than the manual method.
Notes when cleaning air ducts
When cleaning air ducts, note the following:
- Wear gloves, mask, and goggles to protect yourself.
- Do not use strong detergents that may corrode the ductwork.
- Do not use machinery with too much capacity that can damage the air duct.
If you do not have experience or do not have time to clean air ducts, you should hire a professional air duct cleaning service.
