Ladder
The ladder helps you in reaching the ducts. If you are the one who is cleaning the units, you should buy a ladder or borrow from a friend. You can also rent or make your own (using timber) ladder. The ladder that you use should be able to reach the area that you are interested in. It should also be sturdy and well put together.
Brushes
Brushes used should be long-handled and with very stiff bristles. Bristles serve the purpose of agitating dust and debris so that they can be sucked up into a vacuum. For ideal results you should ensure that the brush you use is of the right size and properly fits the duct so that the bristles have full contact with the sides of the duct.
If you consider buying the brushes, you should remember that there are some that are manually operated while others are powered by electricity. If you don't have money to buy new brushes, you should use the ones that you use in scrubbing pans and pots. While these will give you perfect results, they are not ideal for big jobs.
Vacuums
There are two types of vacuums that you can use: the first one fits over the opening of the ducts and creates a negative airflow that prevents agitated contaminates from contaminating the air in the office or home. The second type of vacuum has a long hose that is easy to push through the duct coils and sharp turns.
The vacuums are usually fitted with HEPA filters which aid in ensuring that the exhaust air doesn't contaminate the air quality in the home or office.
Pressure washers
These are only necessary when you want to clean ducts in a room or office that has not been used for a long time. It's also wise to use the tools when toxic contaminates have spread through the ventilation ducts. Experts also recommend that you use the tools when your home has been affected by floods or another natural disaster.
Conclusion
These are the tools that you need to clean your air ducts. When cleaning you should be very cautious in order to avoid injuring yourself.
