How to Maintain Your Air Conditioner in Essendon’s Changing Climate

Essendon’s weather can be as unpredictable as Melbourne’s – with hot, dry summers and cool, damp winters, the climate shifts quickly and often. These changes can place significant strain on your air conditioning system, making regular maintenance more important than ever. If you're relying on air conditioning Essendon services to keep your home comfortable all year round, knowing how to care for your unit will help extend its life, improve efficiency, and lower energy costs.

Here’s a practical guide to maintaining your air conditioner so it performs reliably no matter what Essendon’s weather brings.

1. Clean or Replace Filters Regularly

One of the easiest and most important maintenance tasks is cleaning or replacing your air conditioner’s filters. Dust, pollen, and other airborne particles can clog filters quickly, especially during high-usage months.

• Split systems: Check filters every 1–2 months during summer and winter.
  
  

• Ducted systems: Schedule professional cleaning at least twice a year.
  
  

Dirty filters reduce airflow, making your system work harder and consume more energy. Clean filters not only improve performance but also enhance indoor air quality.

2. Check and Clean the Outdoor Unit

Your outdoor condenser unit is exposed to the elements, which means leaves, dust, and debris can collect around and inside it.

To keep it running efficiently:

• Ensure the area around the unit is clear of shrubs or obstacles (at least 30 cm on all sides).
  
  

• Gently hose down the fins to remove dirt buildup (make sure the power is off).
  
  

• Check for signs of rust or insect nests.
  
  

This will help maintain good airflow and prevent overheating.

3. Inspect and Clean the Coils

Both the indoor evaporator and outdoor condenser coils play a crucial role in cooling efficiency. Over time, these coils collect dirt, which insulates them and reduces their ability to absorb or release heat.

• Use a soft brush or a coil cleaner to remove dust.
  
  

• If heavily soiled, it’s best to have them professionally cleaned.
  
  

Well-maintained coils ensure the system doesn't overwork and maintains consistent temperatures.

4. Check the Thermostat Settings

If you’re using a manual thermostat, make sure it’s calibrated correctly. For better control and energy savings, consider upgrading to a programmable or smart thermostat.

Set the temperature at:

• 24–26°C in summer
  
  

• 18–20°C in winter
  
  

This helps reduce strain on the system while keeping your home comfortable.

5. Inspect Ductwork (For Ducted Systems)

Leaky or dirty ducts can drastically reduce the efficiency of your air conditioning system. If you notice uneven cooling or heating across your home, your ductwork might need attention.

• Check for visible damage, mold, or disconnected joints.
  
  

• Consider having the ducts professionally inspected and cleaned every few years.
  
  

Properly sealed and clean ductwork ensures that conditioned air reaches its destination efficiently.

6. Clear Condensate Drains

Air conditioners remove humidity from the air, and the moisture drains away through a condensate line. If this drain becomes blocked, it can lead to water damage or humidity problems indoors.

To avoid this:

• Inspect the drain line periodically.
  
  

• Use a wet/dry vacuum to clear minor blockages.
  
  

• Contact a professional if you notice water pooling or mold growth near the unit.
  
  

7. Schedule Annual Professional Servicing

While DIY maintenance is helpful, a full system check by a licensed technician once a year is essential. They’ll inspect refrigerant levels, check for leaks, test electrical components, and ensure the system is running at peak performance.

Booking your service before peak summer or winter ensures you’re not caught off guard by a malfunction during extreme temperatures.

8. Be Mindful of Unusual Noises or Smells

Squealing, grinding, or rattling noises—or musty smells—are warning signs of potential problems.

These may indicate:

• Worn-out fan belts
  
  

• Motor issues
  
  

• Mold or mildew in the system
  
  

Address these signs early to prevent costly repairs or health risks.
