If you’ve ever stood under your aircon on a hot day, only to feel it puffing out lukewarm air and a questionable smell—this one’s for you.
Air conditioning is a home essential these days, but when it’s not maintained properly, it can turn from a comfort into a headache. The good news? With the right tools and a little DIY confidence, you can keep your split system running like new—without spending a fortune or calling out a pro for every clean.
This guide walks you through the must-have HVAC tools and cleaning kits that make the job quicker, easier, and more effective.
Why a Clean Split System Matters More Than You Think
Okay, let’s talk about something kinda gross but super important — the inside of your split system. Over time, it becomes a bit of a magnet for dust, pollen, mould, and all kinds of floaty bits you definitely don’t want swirling around your living room.
If you’ve ever turned on your aircon and thought, “Hmm… what’s that weird smell?” — yep, that could be it!
But wait, there’s more. When your filters and coils get clogged up, your poor system has to work extra hard just to cool the room. That means:
It’s like making your car drive up a hill with a backpack full of bricks — not cool, right?
A Simple Clean = Big Benefits
Giving your system a regular clean does wonders. We're talking:
✅ Better airflow — so your home cools down faster
✅ Lower energy use — yay for cheaper power bills!
✅ Less strain on your system — meaning it’ll last much longer
✅ Fresher, cleaner air — no more sneezing fits or mystery smells
This is especially awesome if you’ve got pets, kids, or anyone with allergies at home. Clean filters = cleaner air = happy lungs all around.
Plus, let’s be real — nobody wants to be that house where the aircon sounds like it's about to blast off into space and smells like a damp sock. 😅
The Bottom Line?
Cleaning your split system might not be the most exciting job on your to-do list, but trust us — it’s 100% worth it. Your system will run smoother, your home will feel comfier, and you’ll be saving money in the long run. Boom. 🧼💨💰
Get Started with the Right Cleaning Kit
One of the easiest ways to keep your unit clean is by using a purpose-built cleaning kit. If you're after a full deep clean, a pressure washer-style kit like the Hydrocell A/C Clean Kit is ideal. It includes a Hydrobag to catch runoff, a Tradie Tough pressure washer, and a spray wand designed to get into all the tricky corners of your indoor unit.
If you're new to the process or want something more basic, the Split Air Conditioning Cleaning Kit AC2 is a good place to start. It comes with a catchment bag, cleaning wand, and solution—everything needed for routine upkeep.
Don’t Forget the Coils
The heart of your system—where the cooling magic happens—is the coils. These can become clogged with grime and reduce cooling performance fast.
A safe and effective way to clean them is by using a no-rinse formula like the Air Conditioner Coil Cleaner. It foams up, lifts the dirt, and drains off safely—no wiping or scrubbing required.
For a more powerful option, especially if you haven’t cleaned in a while, the 4x Concentrated Air Conditioner Cleaning Wash Kit goes the extra mile. The concentrated formula means better value over time and more punch per clean.
One Homeowner’s Experience: Fiona’s Story
Fiona lives in a townhouse with two indoor units. After her youngest started sneezing nonstop, she suspected the aircon might be part of the problem. “I took off the cover, and honestly, I was horrified,” she said. “There was so much dust and a smell like wet socks.”
She picked up the Hydrocell kit, followed a quick video tutorial, and tackled the job herself.
“The amount of grime that came out was unbelievable. The pressure washer made it so much easier than I expected. Now the air actually smells fresh, and we don’t get that funky odour anymore.”
Fiona now schedules a clean every six months, using the coil cleaner between major washes.
Maintenance Schedule: How Often Is Enough?
Let’s be real — nobody wants their air conditioner to conk out on the hottest day of summer, right? That’s why regular maintenance is a must-do if you want your HVAC system running like a dream.
So how often should you clean it?
A good rule of thumb is to give your system a decent clean every 6 to 12 months. Think of it like brushing your teeth but for your air conditioner — not every day, but regularly enough to keep things fresh, working, and trouble-free.
But (and this is a big but)... some homes need a bit more love. You might want to clean your system more often if any of these sound like your place:
-
You live near the coast. Salty sea air is great for beach days, but not so great for HVAC systems. That salt can build up inside and cause parts to rust or break down faster.
-
You've got pets. We love our furry family members, but their hair and dander can clog up your filters quickly. If your dog sheds like it’s his job, clean more often.
-
Someone in the house has allergies. Dust, pollen, and other tiny nasties build up in the system, and nobody wants to sneeze their way through summer.
-
You use your aircon all the time. If your system is getting a workout nearly every day, especially in those hot Aussie months, regular cleaning keeps it going strong and saves you from a big repair bill later.
Why bother?
You might be thinking, “It’s working fine… why clean it now?”
Here’s the thing — preventive maintenance is way cheaper (and way less stressful) than emergency repairs. When HVAC systems get dirty or clogged, they have to work harder. That means:
Especially during summer, when every HVAC tech in town is booked out for weeks, you really don’t want your system to give up on you. A clean system means cool air, lower bills, and peace of mind. Now that’s a win-win-win!
Quick Tip!
Set a reminder on your phone to check your HVAC system every 6 months. If the filters look dusty or the unit smells musty, it’s time for a clean. Or better yet — set it to line up with your daylight saving clock change. New time, fresh air!
