Living with allergies or asthma can make everyday environments feel challenging—especially during certain seasons or in homes where dust, pollen, and other airborne irritants tend to accumulate. While many people rely on medication to manage symptoms, there’s another tool that can make a surprising difference: air conditioning. But can air conditioning actually help reduce the triggers that cause allergy and asthma flare-ups? The answer is yes—when used correctly and maintained properly, air conditioning can be an effective part of your overall strategy for improving indoor air quality and minimising symptoms. 

How Air Conditioning Supports Respiratory Health
 

1. Filtering Out Allergens

Modern air conditioning systems are equipped with filters that capture dust mites, pollen, pet dander, mould spores, and other common allergens. By continuously circulating and filtering the air, these systems help reduce the number of airborne particles that might otherwise trigger allergic reactions or asthma attacks. High-efficiency particulate air (HEPA) filters, or filters with a high MERV (Minimum Efficiency Reporting Value) rating, are especially beneficial. They can trap finer particles, making the indoor environment noticeably cleaner and easier to breathe in. 

2. Controlling Humidity

Humidity is a major contributor to the growth of mould and dust mites—two of the most common triggers for allergies and asthma. Air conditioning systems naturally dehumidify the air as they cool it, helping to maintain a comfortable and safe indoor humidity level (ideally between 30% and 50%). This not only makes your home feel cooler and less sticky during hot Australian summers, but also helps limit the conditions in which allergens thrive. 

3. Reducing Outdoor Allergens Indoors

During spring and summer, opening windows might seem like a great way to enjoy the fresh air—but it also lets in pollen and outdoor pollutants. By keeping windows closed and running your air conditioner, you can maintain a cool, clean indoor environment without exposing yourself to seasonal irritants. 

Tips for Maximising the Benefits 

While air conditioning offers potential benefits for those with asthma or allergies, there are a few key things to keep in mind to ensure it works in your favour:

• Keep filters clean and replace them regularly. Dirty filters can become a source of dust and mould, defeating the purpose of having an AC system in the first place.
• Schedule regular maintenance. Professional servicing helps ensure your system is running efficiently and free from internal build-up or leaks that could cause issues.
• Consider an air purifier. If your AC system doesn’t have high-quality filters, a standalone air purifier can offer extra support for allergy or asthma control.
• Seal leaks in ducts and windows. This prevents unfiltered air from slipping into your home and affecting indoor air quality.
   

Choosing the Right Air Conditioning System 

Not all air conditioning systems are created equal, and when it comes to managing allergies and asthma, it’s important to choose one that supports your health needs. Ducted systems and split systems both offer advantages, but it’s crucial to have them installed by experienced professionals who understand how to tailor the system to your home’s layout and your specific requirements.
