Sniff, Cough, Wheeze? Why Your Air Conditioner Might Be Making You Sick (and How Dacs Can Fix It) – Air Conditioning Perth

When the Perth heat rolls in, there’s nothing like stepping into a beautifully cool home. But what happens when your air conditioner — your trusted relief from the summer sun — starts making you feel unwell? If you’ve noticed headaches, sinus irritation, dry eyes, or a persistent cough, your cooling system could be the hidden culprit. The good news? The experts at Dacs Air Conditioning Perth can help you breathe easy again with professional Air Conditioning Repairs Perth and maintenance designed for our tough Western Australian climate.

The Hidden Side of Indoor Comfort

Most people don’t realise that air conditioners do more than control temperature — they also influence air quality. Over time, dust, mould, bacteria, and other airborne particles can build up in your system. When the cool air flows through dirty filters or mouldy ducts, those contaminants are circulated around your home. The result? Poor indoor air quality that can trigger respiratory symptoms, allergies, and fatigue.

In a city like Perth, where many homes run air conditioners for months on end, neglecting system maintenance can quickly lead to health issues. It’s not just about cooling; it’s about keeping your air clean and safe.

Signs Your Air Conditioner Might Be Making You Sick

1. Persistent Allergies or Asthma Flare-ups – If sneezing, coughing, or wheezing worsen when you’re indoors, it might be due to airborne pollutants trapped in your system.
2. Unpleasant or Musty Smells – Mould or bacterial growth inside the unit or ducts often produces an odour similar to damp socks or mildew.
3. Dry Skin, Eyes, or Throat – Poor humidity control can dry out your indoor air, leading to irritation and discomfort.
4. Fatigue or Headaches – Prolonged exposure to poor air quality can cause tiredness or headaches that seem to improve once you leave the room.

These issues are more common than you think, but with a professional service from Dacs, they’re easy to fix — and even easier to prevent.

The Importance of Clean Filters

The air filter in your system is the first line of defence against pollutants. When it’s clogged with dust and debris, your air conditioner has to work harder to push air through, reducing efficiency and allowing particles to escape into your home. Dacs’ air conditioner service Perth team recommends cleaning or replacing filters every few months, depending on usage and environment.

During each service, Dacs technicians inspect and clean filters thoroughly, removing accumulated dust, pet hair, and pollen — all common irritants in Perth households. Clean filters not only protect your health but also keep your system running more efficiently, reducing power bills and extending its lifespan.

Mould and Moisture — The Hidden Problem

Condensation is a natural by-product of cooling, but without proper drainage and ventilation, moisture can accumulate inside the system. This creates the perfect breeding ground for mould and bacteria. Once mould spores take hold, they can spread through your air ducts and into your living spaces.

Dacs’ professional technicians perform a deep clean of coils, drip trays, and internal components during air conditioning repairs Perth to eliminate hidden moisture and microbial growth. They also ensure that drainage systems are clear and that airflow is balanced to prevent future issues.

Air Quality and Energy Efficiency

It’s easy to think of air quality and energy efficiency as separate concerns, but they’re closely linked. A dirty or poorly maintained air conditioner uses more energy to deliver less comfort. When Dacs services or repairs a system, they focus on both performance and cleanliness. This dual approach ensures your system cools faster, uses less energy, and delivers cleaner, fresher air.

Over time, this attention to detail adds up to significant savings — both financially and for your health.
