Is Your Cooling System Ready for Spring? Maintenance Tips

As the weather begins to warm up, many homeowners start switching their air conditioners back on after months of little or no use. The last thing you want is to discover your cooling system isn't working properly on the first hot day of the season.

A little preventative maintenance now can help improve your system's efficiency, reduce energy costs and minimise the risk of unexpected breakdowns during summer. Whether you have a split system, ducted air conditioning or reverse cycle system, these simple maintenance tips can help ensure your cooling system is ready for spring.

1. Clean or Replace Your Air Filters

Your air conditioner relies on clean filters to circulate cool air efficiently throughout your home.

Over time, filters collect dust, pollen and other airborne particles, restricting airflow and forcing your system to work harder.

Cleaning or replacing your filters can:

• Improve airflow
• Increase energy efficiency
• Enhance indoor air quality
• Reduce unnecessary strain on your system

Many filters can be cleaned at home, but it's important to follow the manufacturer's recommendations for your specific unit. It’s often easier and more effective to call in a professional to clean your filters.

2. Test Your Air Conditioner Before the Heat Arrives

Don't wait until the first hot day to turn your air conditioner on.

Running your system for 15–20 minutes in spring allows you to identify any issues before you'll be relying on it every day.

Pay attention to:

• Weak airflow
• Unusual noises
• Strange odours
• Warm air instead of cool air
• Error messages or warning lights

If something doesn't seem right, it's best to arrange a professional inspection before summer arrives.

3. Check Your Outdoor Unit

Your outdoor condenser unit works hard to remove heat from your home, but winter can leave behind leaves, dirt and debris that reduce airflow.

Take a few minutes to:

• Remove leaves and branches from around the unit
• Clear away grass or weeds
• Ensure at least 30 centimetres of clear space around the system
• Check for any visible damage

Keeping the outdoor unit clear helps your system operate more efficiently.

4. Make Sure Your Vents Are Unobstructed

Furniture, curtains or other household items can block air vents, making it harder for cool air to circulate throughout your home.

Walk through your home and check that:

• Supply vents are fully open
• Return air vents aren't blocked
• Furniture isn't restricting airflow

Good airflow helps maintain even temperatures while reducing the workload on your air conditioner.

5. Book a Professional Air Conditioning Service

Even if your system appears to be working normally, an annual service can identify problems before they become expensive repairs.

During a professional service, a technician may:

• Clean internal components
• Inspect electrical connections
• Check refrigerant levels
• Test system performance
• Identify worn or damaged parts

Routine servicing helps maintain efficiency, extend the life of your air conditioner and reduce the likelihood of breakdowns during peak summer demand.

6. Check Your Thermostat Settings

Before summer arrives, make sure your thermostat is operating correctly.

If your thermostat isn't accurately measuring the room temperature, your air conditioner may run longer than necessary or struggle to maintain a comfortable temperature.

Consider programming your thermostat so your system only operates when it's needed, helping reduce energy consumption.

7. Prepare for Higher Summer Demand

Spring is one of the best times to arrange maintenance because technicians are generally less busy than they are during summer.

Booking your service early means you can:

• Avoid peak-season wait times
• Reduce the risk of breakdowns
• Improve your system's efficiency before hot weather arrives
• Enjoy greater peace of mind throughout summer
