G’day, mates! Brendan here from Coalfields Climate Control, ready to share some top-notch tips on keeping your aircon running smoother than a roo on a flat track. Today, we’re diving into a topic that might not sound all that exciting, but trust me, it’s just as important – cleaning your aircon filter. So, grab a cold one, sit back, and let’s get into it.

Why Clean Your Aircon Filter?

You might be wondering why you should bother cleaning your aircon filter. Well, just like your favourite footy jersey, things start to get a bit whiffy if they’re not cleaned regularly. Your aircon is no different. A clean filter means your system runs efficiently, needs fewer repairs, and keeps your home cooler than a polar bear’s toenails without costing you an arm and a leg.
But don’t just take my word for it.

DIY Cleaning: A Good Start, But Not Enough

Now, I’m all for a bit of DIY. There’s nothing like the satisfaction of cracking open a cold one after a job well done. But while giving your aircon filter a good clean can help keep things running smoothly, it’s not a substitute for a professional service.

Think of it like this – you wouldn’t just hose down your ute and call it serviced, right? The same goes for your aircon. Regular cleaning is essential, but every now and then, you need a pro to come in and give it a proper going over.

Your 7 Step Guide to Cleaning an Aircon Filter

Alright, let’s get down to the nitty-gritty. Here’s your step-by-step guide to cleaning your aircon filter:

Step 1: Power Off – Safety first! Make sure your aircon is switched off before you start. This isn’t just about avoiding a zap; it’s also about making sure your system isn’t trying to cool your home while you’re fiddling with the filter. It’s like trying to fill a bucket with a hole in the bottom – not very efficient, right?

Step 2: Remove the Front Panel – This is usually as easy as lifting it up until it clicks and then pulling it towards you. But don’t go yanking it like you’re starting a lawnmower. Be gentle, and it’ll come off easy as.

Step 3: Take Out the Filter – You should see a thin mesh screen. That’s your filter. Slide it out, but be careful not to damage it. It’s tough, but it can still tear if you’re not careful.

Step 4: Give it a Good Clean – Fill up a sink or bucket with warm water and a bit of dish soap. Soak the filter and then gently scrub off any dirt. Remember, we’re cleaning here, not wrestling a croc. Be gentle. And don’t rush this step. The longer you let the filter soak, the easier it will be to get it clean.

Step 5: Let it Dry – Once it’s clean, let it dry completely. No shortcuts here. Trying to put a wet filter back in your aircon is like trying to put a wet swag in its bag – it’s just not going to work. Plus, a wet filter can lead to mould and mildew, and nobody wants that.

Step 6: Pop it Back In – Slide the filter back into place and close the front panel. Make sure it’s seated properly, or your aircon might not work as efficiently as it should.

Step 7: Power On – Flip the switch, and you’re done! You’ve got yourself a clean aircon filter. But remember, this isn’t a one-and-done deal. You should be cleaning your filter regularly to keep your aircon running at its best.

And there you have it, a simple guide to cleaning your aircon filter. It might not be as thrilling as a footy final, but it’s just as important. So roll up your sleeves and give it a go. Your aircon (and your wallet) will thank you.


The Importance of Professional Cleaning

Now, I know what you’re thinking. “Brendan, I’ve cleaned my filter. Job’s done, right?” Well, not quite. While a clean filter is a great start, it’s not the whole story.

Every six months or so, you should get a professional chem clean and service to get rid of all the pollutants and other nasties that can build up in your air conditioning system. It’s like giving your aircon a spa day. It’ll come out feeling refreshed and working better than ever. Plus, it will keep the air quality in your house safe for you and your family.

So there you have it, folks. Cleaning your aircon filter might not be the most exciting job, but it’s an important one. Regular cleaning, combined with professional servicing, can keep your system running smoothly and efficiently.

So, from one Aussie to another, take my advice. Keep your aircon clean, and it’ll keep you cool. Until next time, stay cool and energy-efficient!
