5 Maintenance Tips for Ducted System Air Conditioning

The ducted air conditioning systems in your home are one of the most important pieces of equipment that you can have. They help you stay comfortable in the summer, and they also keep your home's indoor temperature at a level where it won't cause you allergies or illness. Ducted air conditioning is usually more expensive to install than regular window air conditioners, but it can be worth it if you want to get through the warm months without worrying about sweating too much or feeling like there's no way for you to get relief from the heat. And these tips by On Call Air-Conditioning & Refrigeration which provides ducted system air conditioning in Sydney will help keep your DAS unit running smoothly:

Regularly Check the Duct Leaks

A duct leak is a problem that can cause your air conditioner to work inefficiently and may even lead to a breakdown. Ducts can become damaged by insects, rodents or other pests, which can cause them to leak cool air into your home's living spaces.

To detect leaks in your ductwork, use a flashlight to check for signs of daylight coming through cracks around windows or doors (this indicates that warm air is escaping).

Then, listen carefully for sounds associated with escaping coolant from refrigerators, such as hissing noises when opening doors and rattling noises when closing them again. This indicates that warm air is being pulled out of refrigerators.

Replace Air Filters on a Regular Basis

Your air conditioning system requires a properly maintained filter to keep the air in your home clean. You should replace the filter at least once every month, but if you notice that it's dirty or clogged with dust, it's time for an upgrade.

The best way to check whether or not your filter needs changing is by using a simple test. Turn off all fans and other appliances that draw air from around the house (including ceiling fans). Next. open windows throughout the house so that there are no obstructions between outside air and inside space. This will allow any existing odours/smells/dust particles out of the way so they don't interfere with later tests; also note how warm or cool it feels compared with normal temperatures.

Keep the Unit Clean and Dry

When you're cleaning the air conditioning unit, it's important to keep in mind that it needs to be kept clean and dry. This will prevent mould and mildew from forming on the inside of the ducts, which can cause health problems for those who are sensitive to them. It will also help reduce dust build-up in your home. Dust that gets into an air conditioning system can become airborne when you turn on the fan or compressor; this could cause allergies or asthma attacks for those who already have these conditions.[1][2]

Check the Cooling Coil Regularly

The cooling coil is part of your air conditioner that pulls heat from the inside of your home and transfers it to the outdoor unit. This is where moisture collects, so you'll want to check its condition regularly.

Check for damage, leaks and debris around the coil. If you find any signs of mould or mildew on or near it, get help from a professional immediately.

Check underneath your unit for signs of water damage. This could indicate that there's been a leak in your ductwork somewhere along its length. Check around all sides of both indoor and outdoor units (including back panels) for dampness or puddles forming on floors/carpets nearby. This could mean there's been an internal leak somewhere along those lines as well.

Inspect Your Carpet and Flooring for Loose Screws and Nails

It's important to inspect the flooring for loose screws and nails. Loose screws and nails can damage the unit, causing noise and vibration. If you find any loose screws or nails, call a professional to remove them.


Ducted air conditioning units are a great way to cool your home in summer and keep it warm in winter. But they can be expensive to run, so it's important that you look after them properly by following these five tips. If you do this, then your ducted system will last longer and run more efficiently.
