How to Clean an Air Conditioner

Learn effective ways to clean an air conditioner to improve its efficiency and prevent breakdowns.

Learning how to clean an air conditioner can increase its efficiency, prevent breakdowns, and prevent mould, mildew and other allergens from entering the home. Often, air conditioners, whether they are window units or central air systems, are not maintained for months or even years. This can subject the machines to moisture, degradation, and a terribly foul smell of mould and mildew. Follow the steps below to effectively disinfect and clean an air conditioner.

Clean the condenser

  • Vacuum the outside fins to remove debris that blocks the air flow.

Remove the fan and clean the inside fins with a disinfectant cleaner like Dettol® Disinfectant Multi-Use Hygiene Liquid.

Clean the indoor unit

  • With central air systems, a clean air conditioner works best when it also has a new furnace filter. Prevent pollutants and allergens from entering your home with a new filter regularly.
  • Vacuum the blower compartment.
  • Clean a clogged condensation drain with a stiff wire or bleach solution.

For window units

Knowing how to clean an air conditioner that sits in the window saves as much money as cleaning your own central air system.

A disinfected, clean air conditioner will allow for a fresher smell, safer environment, and will help your family remain healthy all year.
