Replace your unit's air filter on a regular basis, at least once a month. The opening that holds its filters can be opened by unscrewing several of its screws.

Swing its door after unscrewing all its screw and its filter will slip out. Measure its filter opening and purchase a filter that is similar in size. A new filter can then be placed replace.

Disable and disconnect the power that supplies the energy to the air conditioner before you start working on any of its parts.

Inspect its fan if it's making any noise. Debris that gets into this area can potentially get caught on its blade and can cause it to bend. When this happens, your air conditioning unit might not work efficiently anymore and can lead you to an expensive repair.

Clean the external covering of the unit. Dust off leaves and dirt that might cling to its outer fins and straighten any bent fins. Bent fans can restrict the entry of air flow which can ultimately affect an air conditioning unit's performance.

Check the unit if it still keeps a proper level. During over-time functions, air conditions can un-level too like any regular appliances, thus reducing its efficiency and effectiveness.

Finally, lubricate its fan motors to complete the maintenance.
