Can Air Conditioning Trigger Allergies?

Spring is just around the corner, which means that many of us will start using our air conditioners a lot more. But with spring comes hay fever for many of us, which begs the question, “Can air conditioning trigger allergies?”

It really doesn’t matter what time of year, whether it’s the first days of spring or a hot summer day. For many hay fever and allergy sufferers, the answer to the question comes down to how well you maintain your air conditioning system. Many factors can exacerbate unpleasant allergy symptoms, like a runny nose or itchy eyes.

Thankfully, there are several ways you can create a healthier indoor environment and reduce the negative effects that your air con has on your allergies. Let’s take a look.

How Air Conditioning Can Affect Allergy Symptoms

For better or worse, it’s certainly true that your air conditioner can have a big effect on your allergy symptoms. Whether that becomes a case of your AC unit making them worse or practically eliminating them from existence, well, that’s up to you to an extent.

A dirty air conditioner or clogged air filters can exacerbate allergic reactions such as sneezing, itchy eyes and congestion. Poorly maintained air ducts can also affect your indoor air quality by spreading mould spores and indoor pollutants.

Even too much dry air flow, particularly cold air, can irritate nasal passages, worsen non-allergic rhinitis, and trigger frequent nosebleeds.

It doesn’t matter whether you have ducted inverter air conditioning or have split system units running in various rooms of the house. Without proper care, neglected systems may even lead to air conditioning sickness and exacerbate allergy symptoms.

Inside your air conditioning system are several key factors that can trigger symptoms in allergy sufferers and negatively impact the quality of air inside your home. Understanding these variables can help allergy sufferers create a healthier indoor environment in a big way.

Keep your senses primed for any of the following:

• Dirty filters – They trap and recirculate allergy-triggering dust mites, pet dander, and pollen particles.
• Mould growth – Wet surfaces and humid environments in coils or ducts help mould spores thrive.
• Poor air flow – Stagnant air allows airborne allergens, harmful bacteria, and airborne viruses to build up.
• High humidity levels – Provide a breeding ground where dust mites thrive.
• Unsealed windows and doors – Allow outdoor allergens to enter, triggering hay fever and seasonal allergies.

Managing these triggers reduces exposure to indoor pollutants, prevents allergens from wreaking unnecessary havoc, and improves air quality throughout your home.

Anyone prone to experiencing allergy symptoms will benefit from improving indoor air quality. Doing so will help your AC unit to circulate air that is fresh, clean and less likely to trigger allergic reactions.

A good starting point to reduce indoor air pollution is to install high-efficiency particulate air (HEPA) filters; these can be highly effective at trapping pollen particles, dust mites, and pet dander. Usng air purifiers with powerful filtering systems will also help to capture allergens and reduce airborne bacteria.

During hay fever season, and especially on high pollen count days, keep your windows and doors closed where and when you can. This will help immensely to prevent outdoor allergens from getting inside the house. Monitor and manage relative humidity levels indoors to kill dust mites and limit mould growth in damp spaces.

Now, don’t get us wrong; as long as you keep your air conditioner well-maintained, you can actually relieve unpleasant allergy symptoms as well and make your breathing easier in fresh, cool air.

Modern air conditioners with powerful filtering systems can capture allergens and improve indoor air quality by preventing them from circulating inside your house. Keeping windows and doors closed during allergy season also helps prevent outdoor allergens from entering your home.

Combined with regular maintenance and clean air filters, your air conditioning unit can support better comfort and fewer allergic reactions.

Like many major appliances in your house, your air conditioning system will always be at its best if you keep it well-maintained with regular servicing.

For the most effective and compliant maintenance and servicing, it’s always best to have it done by an ARCTICK-licensed air conditioning technician. It’s not just that they are the only people legally able to handle the refrigerant gases. A licensed tech will also:

• Inspect air ducts
• Replace air filters
• Clean components that enable mould growth and dust build-up
• Check humidity levels
• Ensure proper air flow to avoid indoor pollutants and airborne bacteria

Here in Australia, using qualified technicians protects the performance of your air conditioner. It also helps the unit maintain compliance with safety standards such as AS/NZS 3666 (Microbial Control) and the Australian and New Zealand Refrigerant Handling Code of Practice.

By trusting your air conditioner to a professional, you also don’t run the risk of voiding the manufacturer’s warranty.

So, can air conditioning trigger allergies? It certainly can, but to what extent depends largely on how well you maintain your air conditioning system.

A dirty air conditioner or an AC unit with severely clogged air filters can make hay fever and other allergy symptoms worse by circulating dust mites, mould spores, and other indoor allergens. But with regular maintenance, your air conditioner can actually improve indoor air quality and reduce allergic reactions.

In the end, it all comes down to having a licensed professional service your air conditioner once every 12 months (or twice a year if you have a reverse cycle, cooling and heating unit) and adopting smart habits like keeping doors and windows shut during hay fever season. You won’t just minimise the likelihood of allergy symptoms flaring up; you might even make breathing easier too!
