Can Air Conditioning Make You Ill?

It’s a question that gets asked a lot, especially during the warmer months: Can air conditioning make you ill? The short answer is no.

Not if your system is properly maintained. Actually, a good air conditioning system can help improve indoor air quality and create a healthier living or working environment.

That being said, there are some common misconceptions worth clarifying. Some people associate air conditioning with colds, sore throats or dry skin, but these symptoms are usually linked to other factors, not the AC itself.

For example, spending long periods in poorly ventilated spaces or environments with low humidity can cause discomfort. However, this isn’t caused by the air conditioner; it’s just a result of how it’s used and the type of environment it’s commonly used in.

So, is AC safe to Use?

Modern AC systems are designed to regulate both temperature and humidity levels. When installed and maintained correctly, they actually help to reduce allergens such as pollen, dust, and mould spores in the air. This can be particularly beneficial for those with asthma, hay fever, or other respiratory conditions.

Where problems can occur is if the system isn’t cleaned or serviced regularly. A poorly maintained unit may circulate dust or bacteria, and clogged filters can impact airflow and performance. That’s why we always recommend regular servicing to keep your system running safely and efficiently.

Another factor is the temperature setting. Constantly sitting in an environment that’s too cold can be a shock to the body, especially when moving between hot outdoor air and very cool interiors. Setting your AC at a moderate, consistent temperature (typically around 21-23°C) can help you stay comfortable without overdoing it.

Air Con Servicing is Key to Staying Safe

The key takeaway? Air conditioning itself doesn’t make you ill, misuse or lack of maintenance might. With the right care and settings, your AC system can make your indoor environment healthier, more comfortable, and more energy-efficient.
