Air Conditioning Maintenance: Keep Your Melbourne Home Cool and Efficient

Melbourne summers are getting hotter and longer. Your air conditioning system needs regular maintenance to run efficiently, keep energy costs down, and avoid breakdowns on the hottest days when every technician in Melbourne is booked solid.

Signs Your AC Needs Attention

Don't wait for a complete breakdown. These warning signs indicate your system needs servicing.

• Reduced cooling power that takes longer to reach your set temperature
• Unusual or musty odours when the system starts running
• Higher than normal energy bills without a change in usage patterns
• Strange rattling, clicking, or buzzing noises during operation
• Water leaking from the indoor unit or ice forming on any component
• Uneven cooling between rooms or hot spots in previously comfortable areas

Monthly DIY Maintenance

These simple tasks take less than 10 minutes and significantly impact your system's performance.

• Clean or replace air filters. This is the single most important maintenance task and the most commonly neglected
• Clear any debris, leaves, or vegetation from around the outdoor unit. Maintain at least 300mm clearance on all sides
• Wipe down indoor unit vents and the return air grille
• Check that the condensate drain line is clear and draining freely

Annual Professional Service

A professional service annually ensures your system operates at peak efficiency and identifies potential issues before they become expensive problems.

• Deep clean of indoor evaporator coils and blower assembly
• Cleaning of outdoor condenser coils which affects overall system efficiency
• Refrigerant level check and top up if needed
• Thermostat calibration to ensure accurate temperature control
• Electrical connection inspection for safety and reliability

Ducted System Maintenance

Ducted air conditioning systems require additional duct cleaning every 2 to 3 years. Dirty ducts circulate dust, allergens, pet dander, and mould spores throughout every room in your home. Clean ducts improve air quality and heating and cooling efficiency simultaneously.

When to Consider Replacement

Air conditioning units typically last 15 to 20 years with proper maintenance. If repair costs exceed 50% of replacement value, or efficiency has dropped significantly despite servicing, consider upgrading to modern inverter technology which uses up to 40% less energy.

Book AC maintenance before summer arrives and avoid the rush.
