Can Air Conditioning Make You Sick? Here’s the Real Story

We have all heard someone say it: “I got sick from the air con!” But is it actually true, or just another myth like cracking your knuckles causes arthritis or sitting too close to the TV ruins your eyes?

If you are a homeowner or business owner in Sydney, you probably rely on air conditioning to survive the summer heat or stay comfy during our weird winter days. But if you are sneezing more than usual or feeling off, it is worth asking the question. Can your air conditioning really make you sick?

Let us break it down with no fluff, no scare tactics, just facts and fixes.

The Short Answer: No, But Also Yes

Air conditioning itself does not cause illness. It does not produce germs or viruses. But if your system is dirty, poorly maintained or blasting cold air like Elsa in a mood, it can contribute to symptoms that feel like a cold, the flu or hay fever.

Regular servicing and proper setup are the real keys to staying healthy with air con.

How Dirty Air Conditioners Can Affect Your Health

Dust, Mould and Bacteria Build Up

When filters are not cleaned or replaced regularly, your system circulates dust, pollen and even mould spores. If you have asthma, allergies or a sensitive nose, this becomes a serious problem.

Some systems also collect moisture, which can lead to mould inside the ducts or coils. Mould is the real villain here. Think less Avengers, more Stranger Things with a fog machine.

Poor Air Circulation Means Stale and Dry Air

Have you ever sat in a meeting room and felt like you were breathing the same air as everyone else? That is what poor airflow does.

Systems that do not bring in fresh air or are set too cold can dry out your throat and nasal passages. This makes it easier for viruses to spread. Dry air can also irritate your eyes and skin. If your office feels like a desert, the air conditioning may be to blame.

Common Symptoms Linked to Air Conditioning

• Dry or sore throat
• Coughing or sneezing
• Blocked or runny nose
• Headaches or fatigue
• Irritated eyes or skin
• Worsening asthma or allergy symptoms

Who Is Most at Risk?

• People with asthma or allergies
• Young children and older adults
• Workers in enclosed offices
• Anyone using a neglected or poorly cleaned system

If the air feels dusty or smells strange, the problem is not just in your head. It could be time for a professional air conditioner clean.

How to Stay Healthy with Air Conditioning

Clean or Replace Filters Often

This is the easiest fix. A dirty filter traps dust and allergens, then spreads them through your home or office. Clean filters mean cleaner air.

See our guide on how often to clean your air conditioner filters.

Book Professional Servicing Every Year

This is not a do it yourself job. Professional servicing checks for mould, bacteria, blocked drains, gas leaks and restricted airflow.

If you are in Sydney, book a service with Arncliffe Babylon. We inspect, clean and maintain all major brands.

Set a Comfortable Temperature

There is no need to freeze. Set the temperature between 22 and 24 degrees Celsius for a comfortable balance. Cold blasts can dry out the air and your throat.

Keep the Air Fresh

Let outside air in when the system is off. If you are shopping for a new system, consider one that includes ventilation options.

Final Word: Air Conditioning Is Not the Enemy

Air conditioning is essential for living and working comfortably in Sydney. It keeps us cool in summer and warm in winter. But like any machine, it needs proper care and regular servicing.

If your air conditioning is making you feel unwell, do not ignore it. A basic service or filter clean can make a big difference.
