If you've been feeling unusually tired, congested, or sneezy at home — your A/C unit could be to blame.

Many Perth homeowners rely on their air conditioning to keep their homes cool and comfortable, especially in the hotter months. But if your system hasn’t been properly maintained, it could be circulating more than just cool air. Mould, dust, and bacteria can build up inside your unit over time, quietly impacting your indoor air quality — and your health.

How Mould Forms in Your A/C

Whether you’ve had your Perth A/C installation done last year or ten years ago, regular cleaning and servicing are essential. Without it, moisture can build up inside the system, particularly around the filters and coils. That damp environment becomes the perfect breeding ground for mould spores — especially in split systems.

Once mould begins to grow, your air conditioner will start blowing those spores around the house every time it runs.

What Can Mould Do to Your Health?

You don’t need to see visible mould for it to cause problems. Even trace levels of mould in your A/C unit can contribute to:

Sneezing, coughing, or sinus irritation
Headaches and brain fog
Itchy or watery eyes
Worsening asthma or allergies
Chronic fatigue or difficulty sleeping

Children, elderly family members, and anyone with respiratory issues are especially at risk.

And because the symptoms can mimic common colds or hay fever, many homeowners don’t realise their Perth A/C system is contributing to the issue.

How Do I Know if There’s Mould in My A/C?

Here are a few signs your A/C might have mould inside:

A musty or damp smell when you turn it on
Visible black or green spots on or near the vents
An increase in allergy-like symptoms indoors
Poor or uneven airflow
It hasn’t been serviced in over 12 months

Even if none of these signs are obvious, mould can still be present in hard-to-see areas. That’s why a regular inspection from a licensed Perth electrician is so important.
