Winter Maintenance Tips for Your Ducted Air Conditioning System

​

As the weather starts to cool down, your air conditioning system may be the last thing on your mind. Regular maintenance not only keeps your system running efficiently but handles the colder months ahead.

Why Winter Maintenance is Important

Winter maintenance is key to preventing unexpected breakdowns, improving energy efficiency, and making sure your system works at its best when you need it most. By taking a few simple steps now, you can avoid costly repairs down the line, extend the lifespan of your system, and ensure your home stays comfortable throughout the colder season.

Clean or Replace the Filters

Your air conditioner’s filters play a critical role in maintaining air quality and system efficiency. Over time, filters accumulate dust, dirt, and other debris, which can clog them and reduce airflow. This increases energy consumption, puts extra strain on the system, and can even cause premature wear and tear.

To ensure smooth operation, clean or replace the filters at least once a year, and more often if you have pets or live in a dusty area. Keeping your filters clean will help your air conditioner run more efficiently, reduce energy bills, and will improve your indoor air quality.

Maintaining Around the Outdoor Unit

Your ducted system’s outdoor unit needs adequate airflow to work efficiently. Leaves, dirt, branches, and other debris can easily block vents and restrict airflow, causing your system to work harder than necessary. This not only increases energy consumption but could lead to mechanical issues if not addressed.

Be sure to clear leaves and debris from around the outdoor unit before the cold arrives, helping it work more efficiently. This simple task helps your system run more efficiently and can make future maintenance and servicing easier. If your outdoor unit is located near a fence, wall, or other obstruction, consider installing air diverters. These can help redirect air flow, making the system more efficient by allowing both cool and warm air to circulate properly.

Controller Settings

As the weather cools, take a moment to ensure your air conditioner is switched to heating mode and set to an optimal temperature—around 20°C to 23°C is ideal for winter.

If you’re still using a traditional controller, consider upgrading to a smart thermostat or using a mobile app for remote control. This allows you to adjust the temperature from anywhere, and many smart systems even learn your routine and adjust the temperature accordingly, helping to optimise energy use and reduce unnecessary heating costs.

Schedule a Professional Service

While cleaning your filters and clearing debris can be handled by homeowners, there are some system components that require professional attention. It’s a good idea to have a qualified technician service your system before winter to make sure it runs smoothly and keeps you cozy throughout the colder months.

A professional service will involve a thorough inspection of the entire system, including checking refrigerant levels, testing electrical components, and cleaning parts that are hard to reach. Technicians can identify issues that could affect your system.

How Often Should Your Ducted System Be Serviced?

Ideally, your ducted air conditioning system should be serviced every 12 months to ensure it operates efficiently and avoids unnecessary breakdowns. However, if your system sees heavy use or is in a dusty environment, it might benefit from more frequent check-ups. Cleaning the filters every 1-3 months is a good idea, especially if you have pets or allergies, as this will keep the airflow strong and the air quality high.
