6 tips to keep your air conditioner cooling as it should

30 January 2017

 A poorly maintained air conditioner needs to work much harder to keep the home cool during the hotter months, particularly after running a reverse cycle air conditioner throughout winter. Over time, a significant volume of dust accumulates on the filter. If left uncleaned, the build-up can clog the indoor unit and reduce air flow, diminishing the performance of the air conditioner.

 Here are six tips to ensure your air conditioning system performs at its best.

1. Clean the dust on the filter

Use a vacuum cleaner, or wash the filter with mild detergent and warm water. Allow the filter to dry thoroughly before replacing. Refer to the manufacturer’s operating manual on how to access and remove the filter from the indoor unit.

2. Keep the outdoor unit free from debris and obstructions.

Like with indoor units, debris can build-up on the outdoor unit fins, restricting airflow. This can cause the compressor to work harder, leading to higher energy usage and increased running costs.

3. Clean the indoor unit grilles.

Dust also accumulates along the grilles of the indoor unit. Gently vacuum along the grooves or wipe with a damp cloth for efficient air flow.

4. Have the air conditioner professionally serviced

Have this done periodically by a licensed air conditioning technician. A professional service every one to two years, depending on usage, ensures the system operates as smooth as possible. 

5. Use built in programmers and features to reduce energy output.

On particularly hot days, use program timers to start the air conditioner before the temperature gets too hot. Switching the air conditioner on during the hottest part of the day means it needs to work much harder and takes longer to cool down the home. Many air conditioners also have a clever human sensor feature which automatically switches the system to energy saving mode when no movement is detected within the room for 20 minutes.

6. Don’t be tempted to set the temperature too low.

Selecting the coldest setting will not cool the home faster, and can instead put pressure on the system. Fujitsu recommends setting the air conditioner above 23 degrees Celsius to create a comfortable environment whilst minimising energy consumption.
