Key Takeaways

Keeping your air conditioner clean is key. It helps the machine work better and keeps the air in your home clean. Before you start any DIY cleaning, always turn off the power to ensure safety.

This simple step can stop accidents.

Cleaning your air conditioning unit often improves its work and cuts down energy costs. Also, it stops dust and other nasty stuff from blowing into your room. So, get a soft brush, a gentle cleaner, and a cloth ready for this task.

Make sure to check everything carefully before turning the power back on after cleaning. This way, you know all parts are safe and set right for running smoothly again. Billy Aircon knows keeping things simple yet thorough makes for happy homes with fresh air.

Method 1: Cleaning Aircon Filters

Cleaning your aircon filters is crucial for keeping the unit running smoothly. It saves energy and avoids unnecessary repair costs. Here’s how you do it:

  1. Turn off your air conditioner before starting.
  2. Gently remove the filter from its slot.
  3. Check for dust and dirt buildup. If the filter looks dirty, it needs cleaning.
  4. Use a soft brush or vacuum cleaner to remove loose dust from the filter.
  5. For a deeper clean, wash the filter with mild soap and warm water.
  6. Rinse thoroughly until the water runs clear.
  7. Let the filter dry completely in a shady spot before putting it back.
  8. Replace the air purifying filters yearly as they cannot be washed.
  9. Plan to clean your filters before cooling or heating seasons start.
  10. Inspect and clean every 2 weeks during high-use periods.

At Billy Aircon, our experience shows that homes with pets or in dusty areas might need more frequent cleaning. Following these steps ensures your air conditioner works well and keeps your air clean.

Method 2: Cleaning the Aircon Condenser and Coils

Cleaning the aircon condenser and coils improves your unit’s efficiency. It ensures your air conditioner works well without extra strain.

  1. Turn off the power to ensure safety before you start.
  2. Remove debris from around the outdoor unit. This lets air flow freely.
  3. Use a vacuum cleaner with a soft brush attachment to gently remove dust and dirt from the coils.
  4. Spray the coils with a no-rinse coil cleaner or mix mild detergent with water for a DIY solution.
  5. Wait for the foam to lift the dirt off for about 15 minutes if using commercial cleaner; if using homemade, gently cleanse with a cloth.
  6. Rinse the coils with water if you used detergent—skip this step for no-rinse cleaners.
  7. Check the fan blades for dirt build-up; clean them with your vacuum’s soft brush.
  8. Straighten any bent coil fins using a fin comb for better airflow.
  9. Allow everything to dry completely, at least 30-60 minutes, before turning the power back on.

This method keeps your air conditioning system running smoothly, saving money on bills and avoiding costly repairs.

Method 3: Sanitizing and Deodorizing the Aircon Unit

Sanitising and deodorising your aircon unit keeps the air fresh and clean. This task ensures a healthier environment in your home. Here’s how to do it:

  1. Turn off and unplug your AC unit to ensure safety.
  2. Use a vacuum with a soft brush attachment to remove dust from the interior components.
  3. Mix equal parts of water and white vinegar into a spray bottle for a homemade coil cleaner. This solution kills mould and bacteria without damaging your system.
  4. Spray the vinegar solution onto the coils and wipe them gently with a soft cloth. Avoid using harsh chemicals that can corrode your coils.
  5. Clean the drain pan using the same vinegar solution to prevent mould growth.
  6. Pour a cup of the mixture down the aircon’s drain line to clear any clogs and eliminate odours.
  7. For cleaning remote controllers, remove batteries first, then wipe them down with a sanitising solution or household alcohol to kill germs.
  8. Natural deodorisers like baking soda can be placed near the intake vents to help absorb odours continuously.
  9. Consider using commercial aircon sanitising sprays designed for AC units if you prefer not to make your own cleaner.
