ac ducts

If you’ve bought an air conditioner (AC) but this is your first time using this machine, then you might not know that it needs to be cleaned regularly. This is especially the case if you have a ducted system. Since ducts are prone to dust and mould, it’s also best to clean your ducts on a regular basis in order for them to work efficiently and to avoid any blockages.

Signs your ducts need a clean 

If you’re unsure about what you should be looking out for, here are the signs that your ducts need cleaning.

  • As mentioned, if you see any mould, you should definitely clean your ducts.
  • If you see any dust particles or waste being released into the air.
  • If you’ve noticed a bad smell coming from your ducts. This can be a sign of insects or rodents invading your unit.

If any of these signs occur, the following preventive measures will help to keep your AC ducts clean.

Regularly change your air filters

Air filters should be changed on a regular basis, and if they become clogged, they should be replaced immediately. If your air filters are dirty, it will fail to filter out any airborne particles and they will continue to circulate within your home. Therefore, it is recommended that your air filters are replaced every 3 months and washed twice a month. However, if you have any pets, it is recommended that your air filters are changed every 2 months. Whenever you check your ducts, make sure that your air filters are in place with no gaps to let air escape.

Clean your drain pans and your evaporator coil

When water is condensed, it can accumulate in your AC ducts, which can encourage the growth of mould. Therefore, it’s important to drain your pans and thoroughly clean your your evaporator coil. The evaporator coil is also known as a cooling coil and your pans are located underneath it. If you’re experiencing mould elsewhere, our article on How to Get Rid of Mould might be helpful.

Seal your supply ducts

If your home is being renovated or under construction, you should make sure that your supply ducts are sealed. If they’re not, dust can enter and settle in your ducts.

Clean your home regularly 

To make sure that not a lot of dust builds up in your home, you should clean it regularly. You should also pay more attention to where dust particles might gather, such as your carpets or your rugs, and ensure that you hoover them on a regular basis.

Make sure you’re keeping your ducts dry

As mentioned in our article about getting rid of mould, moisture can lead to mould growth. Therefore, it’s important to control the moisture in your home. For example, looking for any leaks and fixing them.

Maintain the in-duct humidity

Some units have in-duct humidification equipment. If your system has one, it should be used appropriately to maintain the moisture level. It’s a good idea to read through any manuals or instructions to see if there is a moisture level recommended by the manufacturer.

Seal and insulate

Make sure that you seal and insulate any areas of your home that don’t have an AC unit. This will prevent condensation, as well as moisture from entering your ducts, avoiding mould growth.
