Melbourne doesn’t give you much warning when the heat arrives. One week it’s 18 degrees, and the next there’s a heatwave. By the time you realise your air conditioner West Melbourne isn’t up to the job, you’re already three days into 40-degree temperatures with a system that’s struggling. Preparation is straightforward. Here’s what to do and when to do it.
Do It in Spring, Not on the First Hot Day
The first hot day of the year is the worst time to discover a problem with your air conditioner. Service technicians are fully booked. Every other household in West Melbourne and Melton is in the same situation. The wait can be days.
September and October are the right months. The system hasn’t been under load for months. This is when you want to know if there are issues, not when you’re sweating through them.
Step 1: Clean or Replace the Filters
Start here. A clean filter is the foundation of a well-performing system. After winter, filters are typically dusty from idle periods and any heating use. Remove, clean, and fully dry the filter. If it’s damaged or can’t be cleaned effectively, replace it. This is something most homeowners can do themselves and takes about ten minutes.
Step 2: Clear the Outdoor Unit
Walk outside and take a proper look at your condenser unit. Over winter and spring, debris accumulates. Leaves, grass clippings, seeds, and soil can restrict airflow through the fins. Remove any debris from around the unit, clear at least one metre on all sides, and check that no vegetation has grown into the unit from underneath. Gently rinse the exterior fins with a hose — not a high-pressure washer, which can bend the delicate aluminium fins.
Step 3: Check the Condensate Drain
Find the drain outlet and make sure it’s clear. If it’s been idle for a season, algae and mould can start to build up in the drain line. A blocked drain at the start of summer will cause a leak inside the unit at some point during the season. You can run the system briefly and check that water is draining from the outlet as expected.
Step 4: Test the System Early
Don’t wait until you need the system to find out if it works. On a cool day in October, run the system for 30 to 45 minutes. Check for:
- Adequate airflow from all vents
- The system reaching the set temperature within a reasonable time
- Any unusual noises on startup or during operation
- Any smells, particularly musty odours suggesting mould on the coil
- The outdoor unit operating without unusual vibration or noise
If anything seems off, you have time to get a technician out before the heat arrives.
Step 5: Book a Professional Service
A self-check covers the basics. A professional service covers everything else: coil condition, refrigerant level, electrical connections, motor performance, and a full system test. At New Image Heating & Cooling, our pre-summer services across West Melbourne and Melton include a thorough inspection of all major components. We’ll tell you honestly if anything needs attention.
Step 6: Prepare the House, Not Just the System
Your air conditioner’s performance is only as good as the environment it’s working in. Before summer:
Service the ceiling fans. Make sure they’re running in the correct direction for summer (anticlockwise when viewed from below) and that they’re clean and balanced. Ceiling fans working alongside your air conditioner can let you raise the thermostat by a couple of degrees without losing comfort.
Check door and window seals. Draught strips on external doors and window seals wear over time. A simple draught test — holding a lit incense stick near door edges on a windy day — will show where air is moving. Draught-seal strips are inexpensive and make a real difference to how well a room holds temperature.
Assess your window shading. West-facing windows without external shading are a major source of summer heat load. Roller shutters, awnings, or shade cloth over west-facing windows make a significant difference.
Think about insulation. If your home gets extremely hot very quickly on summer mornings, ceiling insulation may be inadequate. Hot ceilings radiate heat downward and make your air conditioner work against a constant heat source from above.
Step 7: Have the Number Ready
Know who to call before something goes wrong. When your air conditioner Melton stops working at 2pm on a 42-degree day, you don’t want to spend time searching for a reputable local company.
Conclusion
Getting your air conditioner ready before summer can help you avoid unexpected problems when the weather gets hot. A professional service gives you peace of mind that the main parts of your system are ready for the warmer months.
The earlier you prepare, the more time you have to fix any issues before the first major heatwave. If your air conditioner is due for a service or you have noticed something unusual during your checks, now is a good time to get it looked at.

Frequently Asked Questions
When is the best time to prepare my air conditioner for summer in Melbourne?
September or October. This gives you time to book a service, get any parts ordered, and have repairs completed before the first serious heat of the season.
Can I do the pre-summer preparation myself, or do I need a technician?
Homeowners can clean filters, clear the outdoor unit, check the drain, and do a basic system test. A professional service covers the components homeowners can’t safely access themselves — refrigerant, electrical connections, coil condition, and motor performance.
How long does a pre-summer air conditioner service take?
Most residential services take between one and two hours depending on the system type and what’s found during the inspection. New Image Heating & Cooling will give you a time estimate when you book.
My air conditioner passed the basic self-check. Does it still need a professional service?
A self-check confirms the system starts, cools, and doesn’t have obvious faults. A professional service identifies issues developing beneath the surface — worn components, borderline refrigerant levels, coil build-up — before they cause a failure.
What happens if I skip the pre-summer service and the system breaks down in summer?
In peak summer, service bookings fill quickly and wait times extend. You may be without cooling for several days. Parts for older systems may need to be ordered. Pre-summer servicing eliminates this risk.
