If you suffer from allergies, you know how frustrating it can be to deal with sneezing, itchy eyes, and congestion—especially in your own home. While air conditioning helps keep your home cool and comfortable, it can also play a major role in improving your indoor air quality and reducing allergens.
With the right maintenance and strategies, your air conditioning system can help create a cleaner, healthier indoor environment. Here’s how you can use your AC to combat allergies and improve air quality in your home.
Keep Your Air Filters Clean
Your air conditioner’s filters are the first line of defence against dust, pollen, pet dander, and other airborne allergens. If they’re clogged with dirt and debris, they can’t effectively trap allergens, allowing them to circulate throughout your home.
To maintain good air quality:
Check your filters at least once a month.
Replace or clean them regularly, especially during allergy season.
Consider upgrading to HEPA or high efficiency filters, which can capture smaller particles and improve filtration.
Reduce Indoor Humidity
Excess moisture in the air can create the perfect environment for mould and dust mites—two common allergens that can trigger respiratory issues. Your air conditioner helps control humidity levels, but if your home still feels damp, you may need to take additional steps.
To keep humidity in check:
Set your AC to maintain indoor humidity levels between 30% and 50%.
Use a dehumidifier in particularly humid rooms, such as basements or bathrooms.
Ensure your AC’s drain line is clear to prevent moisture build up.
Regularly Clean Air Ducts and Vents
Over time, dust, pet hair, and mould spores can accumulate in your air ducts, spreading allergens every time your AC runs. Dirty vents can also become a breeding ground for bacteria and mould.
To keep your air clean:
Vacuum or wipe down air vents regularly.
Have your air ducts professionally cleaned if you notice excessive dust build up or musty odours.
Ensure your ductwork is properly sealed to prevent outside contaminants from entering your system.
Use an Air Purifier Alongside Your AC
While your air conditioner helps filter out larger particles, an air purifier can provide additional protection against microscopic allergens like pollen, bacteria, and smoke particles.
For the best results:
Place an air purifier in high traffic areas or bedrooms where allergens tend to accumulate.
Choose a purifier with a HEPA filter for maximum air cleaning efficiency.
Use it alongside your AC to continuously refresh and purify the air in your home.
Keep Your AC Coils and Drains Clean
Your air conditioner’s evaporator coils and drain pan can collect moisture, creating the perfect conditions for mould and bacteria growth. If left unchecked, these contaminants can be released into the air, worsening allergy symptoms.
To prevent this:
Schedule regular AC maintenance to clean the coils and drain lines.
Use a mild detergent or vinegar solution to clean the drain pan and prevent mould build up.
Ensure your AC unit is well ventilated and free of standing water.
Keep Windows and Doors Closed During High Pollen Seasons
While fresh air is great, opening windows during peak allergy season can bring in pollen and other outdoor allergens. If you rely on air conditioning for cooling, keeping doors and windows closed can help maintain a controlled indoor environment.
To further reduce allergens:
Use weather stripping to seal gaps around doors and windows.
Avoid drying clothes outdoors, as pollen can cling to fabrics and be brought inside.
Shower and change clothes after spending time outside to minimise pollen exposure indoors.
Schedule Regular AC Maintenance
Even if your air conditioner appears to be running fine, regular professional maintenance is essential for keeping your indoor air clean and allergen free. A technician can inspect your system, clean components, and ensure everything is functioning efficiently.
Professional maintenance can:
Improve your AC’s efficiency and air filtration.
Prevent mould and bacteria build up.
Extend the lifespan of your system while keeping your home’s air quality at its best.
