An air conditioning system is one of the most important assets to the modern home in South East Queensland, especially with our long, humid summers. Whether it’s a split system or a central ducted AC system throughout the home, the efficiency of the equipment is vital for in-home comfort and air quality.

 

Like all machinery, regular maintenance and upkeep are crucial to ensure optimum performance. Poorly maintained systems lose efficiency over time while reducing the air quality in the home, leading to higher energy bills and expensive repairs.

 

While professional servicing should be completed annually, there are some simple maintenance steps you should complete between visits. We’ll walk you through these steps and provide further information on preventative servicing.

What a Professional Service Entails

There are many items your service technician will cover in their detailed report, including findings and recommendations.

Specific items we cover include:

End User Servicing Tips

The Return Air Filter

The most important maintenance step for the end user is to ensure that the return air filter is kept clean. On your split system, this is behind or above the front cover. On your ducted AC system, this is within the return air grille where the air is drawn in. Always take note of how the filter came out to ensure it is returned correctly. If you are unsure how to access your filter, we’re happy to walk you through the process. 

When cleaning the filter, always inspect for tears in the filter or clogging that cannot be removed. This is normally a sign it’s time for a filter replacement. For washable filters:

The System Controller and Thermistors

Ensure your controller and any thermistors have operating batteries. The main controller often has a built-in thermistor; ensure this and any individual sensors are always open and not covered. Remove any controllers and thermistors before painting and clean any dust off them.

 

Don’t ignore maintenance warnings! Get them actioned as soon as they appear. Call us if a professional visit is required

The Outdoor Unit

There are some simple steps to ensure your outdoor unit doesn't cause system issues.

A common issue is geckos; although efforts are made, no unit is completely sealed. Keeping mothballs or silverfish repellent in your ODU can help keep critters out.

How Often Should You Complete a Professional Service?

Residential ducted and split air conditioning systems should be serviced annually. We recommend routine servicing before winter heating begins.

During summer, the unit processes a high volume of water, which can lead to mould build-up and potential drain issues. We want the coil cleaned before heating starts, as a hot coil with mould can reduce air quality—often perceived as a musty smell in heating mode.
