We rely on our air conditioning systems to keep us cool in summer and warm in winter. Regularly cleaning your air conditioner is crucial to maintain efficiency and improve the indoor air quality of your home, helping to protect the health of you and your loved ones. In this blog post, we provide tips on how to clean your home air conditioning system and general maintenance tips to help keep your air conditioner running smoothly.  

Why should you clean your air conditioner?

According to Healthy Building Systems Australia, up to 50% of illnesses are a result of poor indoor air quality. Air conditioners are a paradise for bateria, mould, fungi, pet hair, dust, smoke, pathogens and viruses. By regularly cleaning and servicing your air conditioning system, you will be taking steps to improve the health of yourself and your loved ones.

Having a dirty, clogged up air conditioner system also impacts the efficiency and lifecycle of the system and increases risks of fire and critical breakdowns. Regular servicing of your air conditioner can improve system efficiency and energy-efficiency. 

How to clean air your conditioner 

Most modern air conditioning systems have self-cleaning functions. But it’s a good idea to conduct a proper hands-on clean every year to remove the dirt and dust that builds up over time. 

Before you attempt any cleaning work, ensure the air conditioner is switched off – at the wall and in the outside electric box.

Please note, the following steps are suitable for cleaning split system air conditioners. Cleaning ducted air conditioners is a more complex job that requires the help of professionals. 

The Outside Unit

  • Use a broom to remove any large chunks of dirt, spiderwebs and leaves on and around the outside of the unit
  • Clean the condenser fins (metallic blades) surrounding the unit, using a vacuum cleaner
  • Remove the fan and clean the inside of the unit with warm water

If you notice the fan blades inside the unit are bent, you can attempt to straighten them out yourself with a butter knife, however we recommend calling a professional to prevent further damage and risk of personal injury. 

The Inside Unit

  • Place an air conditioner bag under the unit
  • Remove the filters, wash in warm water and let it dry
  • Spray the coils and blades with a coil cleaner and leave for 20mins
  • Rinse off the cleaner with a water spray
  • Run the air conditioner and wait until all the water from the unit runs onto the bag

General Maintenance Tips 

After you’ve conducted a thorough clean of your air conditioner, here are a few things you can do to keep it clean and working to optimum efficiency:

  • Spray an anti-bacterial spray on all components that have been cleaned, including the filters, fan coil, drip pan and tube. 
  • Clean the unit’s drop channels with a wire or pipe cleaner to remove any obstructions

In addition, there are a number of steps you can take throughout the year to ensure your air conditioner is in tip top condition. 

Every Use

If your air conditioner has a ‘dry out’ function, run it after every use to remove moisture, prevent mould and foul odors. 

Bi-anually

Clean and/or replace the dust filters and wipe down the unit with a damp cloth to remove dust. At the beginning of summer and just before heating in winter are great opportunities to do this. When it comes time to replace the filters, make sure you purchase filters that are specifically designed for your air conditioner make and model.  

Annually 

Conduct a deep clean of the outdoor and indoor units, as outlined above.
