How often should I get my air conditioner cleaned?

Air conditioner cleaning: When and why it matters

Air conditioners are a vital part of any home, especially in Redcliffe’s warm climate. 

To keep your air conditioner working efficiently and to ensure the quality of the air in your home, regular cleaning is essential.

While you may be able to handle basic air conditioner cleaning yourself, you will  need the expertise of a professional air conditioner cleaning team like Hays Airconditioning for deep cleaning and sanitising.

How often should you get your air conditioner cleaned?

Before we delve into the frequency of cleaning, let’s address the signs that indicate your AC needs a good cleaning.

How do I know if my AC needs cleaning?

Reduced cooling efficiency

If you notice that your air conditioner isn’t cooling your space as effectively as it used to, it might be time for a clean.

Strange odours

Unpleasant odours coming from your AC when it’s running can be a clear sign of dust or mould buildup.

Allergies or other respiratory issues

If you or your family members experience an increase in allergies or respiratory problems when the AC is running, it might be due to a dirty filter or vents.

Visible dust and debris

Take a look at your AC’s vents and filters. If you see a buildup of dust and debris, it’s a sure sign that cleaning is overdue.

Now, let’s address the core question: How often should you clean your air conditioner in Brisbane?

The frequency of AC cleaning depends on several factors:


If you use your AC daily, it’s advisable to clean it more often. A general guideline is to clean it every 6 to 12 months.


If you or your family members have allergies, it’s a good idea to clean your AC every 3 to 6 months.

Pollen and dust

In Brisbane, where pollen and dust can be a concern, more frequent cleaning, every 3 to 6 months, is recommended.


If you have pets, their fur and dander can quickly accumulate in your AC, so cleaning every 3 to 6 months is essential.

Regular cleaning not only ensures better air quality but also extends the life of your air conditioner, saving you money in the long run.

For the best results, consider hiring a professional like Hays Air Conditioning for your AC cleaning needs. We are well-equipped to handle the unique conditions in Brisbane.

The importance of regular air conditioner cleaning

Maintaining a clean air conditioner is not just a matter of comfort; it’s essential for several reasons:

Enhanced cooling performance

A well-maintained air conditioner cools your home more effectively. When the coils are free from dirt and grime, they can exchange heat more efficiently, resulting in a cooler and more comfortable indoor environment. This means you won’t have to set your thermostat as low, further reducing energy usage.

Improved indoor air quality

Your air conditioner not only cools the air but also filters it. When the filters are clogged with dust and contaminants, the air quality in your home can deteriorate. Regular cleaning ensures that your AC system can effectively filter out allergens, dust, and pollutants, providing cleaner, healthier air to breathe.

Cost savings

Preventive maintenance, which includes regular cleaning, is more cost-effective than waiting for a breakdown to occur. Repairing or replacing a damaged AC system can be expensive. By investing in routine cleaning, you can avoid these hefty costs and ensure your air conditioner serves you well for years.

Reduced environmental impact

A well-maintained AC system consumes less energy, reducing your carbon footprint. This is an eco-friendly choice that contributes to a cleaner environment.

What happens if you don’t clean your AC?

Neglecting to clean your air conditioner can lead to a range of problems, including:

Reduced efficiency

A dirty AC has to work harder to cool your home, resulting in increased energy consumption and higher bills.

Health issues

The accumulation of dust, mould, and bacteria can lead to health problems, especially for those with allergies or respiratory issues.

Foul odours

Dirty air conditioners can emit unpleasant smells, making your home less inviting.

Shortened lifespan

The strain caused by dirt and debris can reduce the lifespan of your AC, leading to costly repairs or replacements.

Lower cooling capacity

A neglected AC may not be able to cool your space effectively, leaving you uncomfortable during hot Brisbane summers.

DIY vs. Professional AC cleaning

DIY AC cleaning

No doubt the most attractive benefit is that DIY cleaning can save you money on service charges. Simple tasks like cleaning or replacing filters can be handled by homeowners. 

However, for deep cleaning and sanitation, your best bet is to choose a licensed professional with the tools and know-how to provide an effective cleaning service. 

Professional AC cleaning


Professionals have the knowledge and tools to clean every part of your AC effectively.

Thorough cleaning

They can remove mould, bacteria, and dirt that DIY methods might miss.

Health benefits

Professional cleaning improves air quality and reduces health risks.


Regular professional cleaning can extend the life of your AC, saving you money in the long run.

While DIY cleaning has its place for routine maintenance, it’s essential to have professionals like Hays Airconditioning handle comprehensive cleaning to ensure optimal performance and air quality.
