5 Reasons to Clean Your Air Conditioning Ducts

5 Reasons to Clean Your Air Con Ducts

Air conditioning. It’s a luxury we rely on to remain comfortable in the hottest and coldest months of the year. As the Australian Government’s Energy website suggests, the air con can account for between 20 to 50 percent of energy use (depending on climate zone) in homes across the country. But as Peter Parker (aka Spiderman) learned; ‘with great power comes great responsibility.’ So too does great responsibility exist with owning an air conditioner.    

For homeowners with ducted air conditioning, the importance of keeping those ducts cleaned is crucial. There are numerous reasons why it’s vital to maintain clean air con ducts; let’s look at them in more detail.

But First, A Ducted Air Conditioning Refresher

Let’s look at how ducted air conditioning works to better understand the importance of why they need to be regularly cleaned. 

Ducted air conditioning systems feature two main units, one located indoors and the other outdoors. The indoor component draws in air via a return duct. Warm air in your home moves through the return duct and is cooled by the external compressor during warmer months. A fan inside the ducted air conditioner pushes and cools your air over a series of refrigerant pipes. Chilled air is transported back through the home via your roof’s air ducts.

Conversely, warm air is absorbed from outside during colder months as the process effectively works in reverse. Additional zone controls and temperature settings mean you can have tailored climate control.

The Importance of Maintaining Clean Air Conditioner Ducts

As the heated or cooled air is distributed through your home by the ducts in the ceiling, ensuring they stay clean is of utmost importance. This is for a number of reasons. 

Your Home Will Be Cleaner

Air conditioner ducts collect all sorts of impurities including dirt, dust and pollen among others. These impurities can be blown throughout your house, leaving piles of dirt and dust if left to build up. Having your ducts cleaned will reduce these buildups that can then be blown throughout your home. 

Your Home Will Be Healthier

In addition to leaving unsightly messes through the house, these buildups of dirt, dust and pollen can trigger allergies. Unfortunately, these allergens can result in anything from asthma symptoms to skin rashes, eye irritation, nausea and more. 

Mould spores can also grow in air conditioning ducts. They can cause long lasting respiratory issues if left to grow and spread throughout the home. Regular duct cleaning will reduce the likelihood of these mould spores being spread by your air conditioning system, making your home much healthier. 

Your Air Con Will Be More Energy Efficient

Dirty air conditioning ducts mean that your air con has to work harder to provide an optimal level of performance. The collected dust and debris in the ducts force your air conditioner to use more energy to work around the reduced air flow. A clean pathway therefore means your air conditioner can operate at optimal efficiency without going over and above with the consumption of energy. And of course, improved energy efficiency is better for your household energy budget!

Keep your air fresh with clean air filters and vents.

Your Air Conditioner Will Last Longer

Meanwhile, to extend the lifespan of your air conditioner, regular duct cleaning is one of the best things you can do. Clearing the ducts of all dirt, dust and debris helps to reduce the need for potentially expensive repairs and aids in prolonging the life of your unit. It’s a simple step that’s often overlooked. Thankfully, it’s not hard to provide long term care for your ducted air conditioning.

Your Home Will Be Free of (Most) Unpleasant Odours

The unpleasant odours coming from your air conditioner, at least. 

If your air conditioning duct work has mould growing within it, the smell can permeate through your home when the AC is turned on. Cleaning the ducts of your air conditioner will help to remove the mould from the system, which in turn will eliminate the smell from your home. 

How Often Should I Have My Ducts Cleaned?

Cleaning experts and specialist air conditioning technicians recommend professionally cleaning your air con ducts every two to four years. However you may benefit from more frequent cleans, perhaps even every six months, if any of these apply to you:

  • You have pets
  • You suffer from allergies or asthma
  • You live with respiratory problems
  • There are toddlers or elderly people living in your home
