How often should I clean the filters in my air conditioner? How do I clean the air filters?

The frequency and type of cleaning will depend entirely on what type of system you are using whether it is ducted or split.

For a ducted system – the return air grille, which is normally located in a hallway has a bolt that unscrews. The return air grille is on hinges which will swing down, the filter inside will need to be pulled out, hosed with water the opposite way that the dust gets trapped to ensure all dust is cleaned from the filter. The recommended cleaning frequency for this is every 1-2 months depending on the use of the system.

For a split system there are two tabs on either side of the face of the unit. Gently lift these tabs up, the face of the unit will stand up, pull the filters out. Hose the filters in the opposite direction of trapped dust. This will need to be done every 1-2 months depending on how often the system is used.

For both systems, make sure the filter is dry before placing the filter back into the system.

Depending on the type and grade of your filter, consider a replacement every 3 months. These filters are not meant to last forever, especially when your AC is used on a daily basis.
