Perth’s February heatwave can be relentless, with temperatures frequently exceeding 35°C. During these scorching days, your air conditioning system works overtime to keep your home comfortable. However, increased usage can lead to several common AC problems.

If your air conditioner isn’t keeping up with the heat, you’re not alone. Many Perth homeowners face AC issues during peak summer. Here’s what to look out for—and how to fix them before they escalate.

1. Insufficient Cooling

Problem: Your air conditioner is running, but it’s struggling to cool your home. There can be a long list of possible causes, however some of the main reasons are generally the simplest, clogged filters, dirty coils, poor ducting design or a failing compressor.

Solution:

    • Clean or replace air filters to improve airflow.
    • If cooling issues persist, consider air conditioning servicing in Perth to check the efficiency of your system and overall system performance.

    2. Weak Airflow from Vents

    Problem: Your AC is on, but there’s barely any airflow coming from the vents. Blocked filters, a faulty fan motor capacitor, or ductwork issues could be the cause.

    Solution:

    • Clean air filters to restore airflow.
    • Ensure a local contractor can assess zoning inside your roof space, check over condition of your ducting and make sure air leakage is tested
    • If the issue persists, air conditioning repairs in Perth can help diagnose and fix the problem efficiently.

    3. Continuous Operation Without Effective Cooling

    Problem: Your air conditioner is running non-stop but still struggling to maintain a cool temperature. This could be due to an undersized unit, dirty coils, or compressor efficiency.

    Solution:

    • Ensure your AC is the correct size for your space.
    • Clean the outdoor condenser coils for better efficiency.
    • For ongoing issues, air conditioning servicing in Perth can help keep your system in peak condition.

    4. Unusual Noises from the AC Unit

    Problem: If you hear rattling, buzzing, or grinding sounds, it could indicate loose components, a failing motor, or refrigerant issues.

    Solution:

    • Turn off the unit and check for loose screws or debris near the outdoor unit itself.
    • If the noises persist, WeztOz Innovative Air Solutions can resolve any mechanical or refrigerant-related issues, on the high amient days we find compressors and outdoor fan motors that have underlying issues will begin to show major issues.

    5. Water Leakage from the Indoor Unit

    Problem: Water pooling around your indoor AC unit usually signals a clogged condensate drain, frozen evaporator coils, or in some cases refrigerant problems.

    Solution:

    • Use a wet/dry vacuum to clear any drain blockages.
    • Indoor fan motor may have an underlying issue that needs to be rectified
    • If leaks continue, air conditioning servicing in Perth can prevent further damage.

    6. Warm Air Blowing Instead of Cool Air

    Problem: Your air conditioner is blowing warm air instead of cooling. Possible causes include incorrect thermostat settings, a refrigerant leak, or compressor failure.

    Solution:

    • Double-check that the thermostat is set correctly. You would be surprised how many people have the system on heating and wonder why its not operating as needed. If its a symbol, then choose the snowflake (Cooling sign).

    7. Rising Energy Bills During the Heatwave

    Problem: A sharp increase in your energy bill could indicate that your AC is overworking due to dirty filters, poor insulation, or an ageing unit.

    Solution:

    • Schedule air conditioning servicing in Perth to improve energy efficiency.
    • Upgrade home insulation to reduce cooling demands.
    • If your unit is outdated, upgrading to an energy-efficient model can save on long-term costs.
