Comprehensive Air Conditioner Maintenance Guide for Melbourne Homeowners

February 13, 2025

Keeping your air conditioner in peak condition is essential for Melbourne homeowners, especially with the city’s unpredictable weather patterns. Regular maintenance ensures your system runs efficiently, improves indoor air quality, and extends its lifespan. At Legacy Trade Services, your trusted electrical and air conditioning partner in Melbourne, we understand the importance of proper air conditioner upkeep. This guide will walk you through essential maintenance tips to keep your unit performing at its best.

Air Conditioner Maintenance

Why Regular Air Conditioner Maintenance is Important


Neglecting air conditioner maintenance can lead to:

  1. Reduced efficiency results in higher energy bills.
  2. Poor indoor air quality due to dust and mould buildup.
  3. Increased risk of breakdowns and expensive repairs.
  4. A shorter lifespan for your air conditioning system.


By following a consistent maintenance routine, you can ensure your unit operates smoothly throughout the year.


How Often Should You Maintain Your Air Conditioner?


Melbourne’s climate varies throughout the year, meaning your air conditioner needs regular attention. Here’s a basic guideline:

  • Every 1-2 months: Clean or replace filters.
  • Every 6 months: Inspect and clean the outdoor unit.
  • Annually: Schedule a professional service with Legacy Trade Services.
  • As needed: Address any unusual noises, odours, or performance issues.


DIY Air Conditioner Maintenance Checklist


While professional servicing is crucial, there are simple maintenance tasks you can do yourself to keep your unit in top condition.


1. Clean or Replace Air Filters

Dirty filters reduce airflow and strain your system, leading to higher energy consumption. To maintain efficiency:

  • Check filters every month, especially during peak summer and winter seasons.
  • Clean reusable filters with water and mild detergent.
  • Replace disposable filters as recommended by the manufacturer.


2. Keep the Outdoor Unit Clear

The outdoor condenser unit can become clogged with leaves, dirt, and debris, impacting its performance. To prevent this:

  • Regularly remove leaves and dirt from around the unit.
  • Trim nearby plants or bushes to allow at least 60 cm of clearance.
  • Gently hose down the unit’s exterior to remove dust buildup.


3. Check for Unusual Noises or Odours

Strange sounds or smells can indicate potential issues. Look out for:

  • Grinding or buzzing noises: Could mean loose components or motor problems.
  • Musty odours: May suggest mould buildup inside the unit.
  • Burning smells: A sign of electrical issues requiring immediate attention.
  • If you notice any of these, Legacy Trade Services can diagnose and fix the problem.


4. Inspect the Thermostat

An inaccurate thermostat can cause your system to work harder than necessary. To ensure proper function:

  • Check that the thermostat settings match the indoor temperature.
  • Consider upgrading to a programmable or smart thermostat for better energy efficiency.
  • Replace batteries if applicable.


5. Ensure Proper Airflow

Blocked vents and registers can strain your system. Improve airflow by:

  • Keeping furniture and curtains away from vents.
  • Cleaning dust from vents with a vacuum or duster.
  • Ensuring doors and windows are properly sealed to maintain indoor temperature.


When to Call a Professional for Air Conditioner Maintenance


While DIY maintenance helps keep your unit running efficiently, professional servicing is essential for a thorough check-up. Legacy Trade Services offers expert air conditioning maintenance in Melbourne, ensuring your system remains in top condition.


A professional service includes:

  • Deep cleaning of coils and internal components
  • Refrigerant level checks and top-ups if needed
  • Electrical and mechanical inspections
  • System performance testing


It’s recommended to schedule a professional air conditioner service at least once a year, preferably before summer, to ensure peak performance.


Energy-Saving Tips for Melbourne Homeowners


Besides regular maintenance, you can improve your air conditioner’s efficiency with these energy-saving tips:

  • Set your thermostat to an optimal temperature: 24–26°C in summer and 18–20°C in winter.
  • Use ceiling fans: Helps distribute cool or warm air more effectively.
  • Close blinds and curtains: Reduces heat gain during hot days and retains warmth in winter.
  • Avoid excessive use: Turn off the system when not needed to save energy.
