Top Essential Tips for ducted air conditioner maintenance

It is true that we are blessed with comfort and convenience gifted by technology. One such blessing is a ducted air conditioner. When the days get longer and the sun seems to have more bite than usual, surely it’s a sign of summer and a sign of starting to use an air-conditioner daily.

To be precise, the ducted air conditioner isn’t cheap. We have to spend thousands of dollars to install a system at our house. Therefore, it is crucial to understand how to maintain and take care of the system to ensure they last longer. For sure, we can always trust companies like Omni Air Conditioning for any repair associated with ducted air conditioning in Sutherland Shire.

But there are certain DIYs that you can do yourself to add life to your expensive ducted air conditioner. These are the top essential tips for ducted air conditioner maintenance.

1. Change the filters

One of the most important and easiest ways to keep a ducted air conditioner in the notch position is changing filters. To ensure that the ducted system works efficiently, we need to change and clean filters at a minimum once every six months. Filters can be changed without any trouble. All we need to do is locate your unit’s filter slot, slide out the old filter and insert the new one, making a note of the direction of the airflow and which side of the filter needs to face out.

Make sure to read out the manufacturer’s instructions without fail and follow every step and instruction properly. Also, ensure that you use the right type of filter for your ducted system. For the right filter, contact the professional who installed the system or contact the manufacturer.

2. Do a little cleaning

This is the foremost thing we have to keep doing every year. No matter whether we have changed filters recently, cleaning is very important. Most of us forget or overlook cleaning the ducted system until we notice a degrade in performance.

Over time, the system will collect all the dust and debris, and this will not only affect the performance but will also make the air impure and unhealthy. Make sure all the indoor vents are clean. Next, pour a cup of bleach mixed with warm water down the drain of the outside unit to prevent mould and algae buildup. Then ensure the unit:

  • Is on a level surface
  • Doesn’t have any debris, such as leaves, dust, pollen, and twigs, clogging it up.
  • Has at least 2 feet of clearance around it
  • Has the proper amount of good-quality insulation around the refrigerant lines.

Pro tip: it is always a good idea to call a professional before summer for professional cleaning and service. If you are looking to install ducted air conditioning in Sydney, walk straight to Omni Air Conditioner.

3. Assess your Ac’s performance

After you have changed filters and cleaned the vent, it’s time to check that baby’s performance. Determine if your home is getting cooler. If the unit is quiet or making any disturbing noise and if it appears to make any noise or not delivering the desired cooling, call a professional. Omni Air Conditioning provides the best services for all types of air conditioning in Sydney.

Note: The first time when you start the system after cleaning the vent or filters, you may notice a smell. That’s simply because of the air conditioner’s way of cleaning out the dust that may settle since the last time you ran the unit. But don’t worry, it will dissipate shortly.


Perhaps after taking all the precautionary steps, the unit might stop working or is not given expected cooling or in the worst case, it’s not even blowing air, it’s time to call a professional. They can answer all the answers efficiently. Also, always make sure that you contact a well-experienced professional for ducted air conditioning installation in Sydney because correctly installing the unit is very crucial for optimal performance.
