Cleaning your Aircon Filters:
Give Your iZone System the Best Chance to Perform at Its Peak
Cleaning your air conditioner filters is crucial as it directly impacts your wallet, health, and comfort.
Cost Savings and Improved Energy Efficiency:
A clogged air filter forces your air conditioning unit to work harder, much like trying to breathe through a blocked nose. When filters are clean, air flows freely, reducing the strain on your AC unit. This leads to lower energy consumption and noticeable savings on your electricity bill.
Extended System Lifespan & Reduced Repair Costs:
A dirty filter forces your AC to work overtime, putting strain on critical components like the compressor and fan motor. This can lead to premature breakdowns and costly repairs. Clean filters reduce this strain, keeping your system running smoothly and lasting longer.
Enhanced Indoor Air Quality & Health:
When filters are clogged, dust, pollen, and mould can build up and recirculate through your home, affecting air quality and health. Clean filters effectively trap these particles, ensuring cleaner, fresher air circulates throughout your home. This is especially important for those with allergies or asthma.
Consistent Comfort:
A dirty filter restricts airflow, causing uneven cooling and “hot spots” around your home. Clean filters ensure consistent, powerful airflow, providing uniform cooling and easily maintaining your set temperature.
Smart Monitoring: Your Aircon’s Efficiency Indicator
iZone’s Smart Power Monitoring helps you track where your energy is going and reduce your electricity bill by scheduling appliances to run during off-peak hours. You might notice an unexplained spike in your AC’s energy consumption with a power monitor, even with smart schedules. This could be a direct sign of a clogged filter forcing your unit to work harder, consuming more power.
How Often Do You Need to Clean Your Aircon Filter?
iZone’s Nova, Nexus and Nano Systems include a filter cleaning reminder, which helps stay on track. Ducted air conditioning systems, filters should generally be cleaned every three months, depending on usage and environment.
Guidelines for cleaning
Every three months
If you use your system often
If you have pets that shed
If anyone in the household has allergies or asthma
If you live in a dusty or high-pollen area
If there’s smoking inside the house
Minimum Cleaning
Clean your filters at the start of each heating or cooling season.
In addition to cleaning your air conditioner filter, we recommend having it professionally serviced every one to two years for optimal operation and to detect any issues early. Just like your car, your air conditioner has an engine that benefits from regular servicing each year.
How to Clean Your Ducted Aircon Filter
For ducted air conditioning systems, you’ll typically find the filter in the return air grille. This large, grid-like panel is usually on the ceiling in a central hallway or living area, but sometimes it’s on a wall. To confirm it’s the correct grille, turn on your air conditioning fan and check if air is being drawn into it.
To clean the filter:
- Switch off the aircon.
- Remove the filter from the return air grille. Take care the grille doesn’t hit you.
- Vacuum loose dust, then rinse with a hose. Don’t soak the filter in water.
- It’s important to let it dry fully.
- Reinstall the dry filter and close the grille.
Some air conditioning filters, such as HEPA, disposable pleated, and spun glass types are generally not washable and should be replaced when dirty. Refer to the filter itself for a manufacturer’s label or instructions.
Get Ahead of the Summer Rush
Avoid the Rush. If something’s not right, you’ll want time on your side – installers book out fast once the heat sets in.
Breathe Easier. Summer brings a spike in pollen and outdoor allergens. Clean filters help keep your indoor air fresh and healthy.
Boost Efficiency. A clean system works smarter, not harder, saving energy and keeping things cooler for longer.
Prevent Breakdowns. Don’t let a clogged filter cause a mid-summer meltdown. Stay ahead of wear and tear.
