Do You Have Mould In Your Air Conditioning Unit? Here’s Some Tell-tale Signs For You

What’s the state of your air conditioner unit right now?

A clean air conditioning unit is necessary because our health may be at stake. Imagine this: mould might be having a party in your air-con while chilling inside. And trust us, that's not a gathering you want. 

Mould doesn't just make your AC work harder; it can also throw a bunch of health curveballs your way. From sneezes to more severe respiratory issues, the risks are real. Mould is widespread in warm, moist environments that don’t get a lot of light. And what causes it to exist? The dust and dirt build-up in the filter make it an excellent breeding ground for it. 

But here’s the good news. We can prevent it! Just clean and replace your filter regularly. Let’s use this guide to help you look for signs of mould growth. We also included some tips on how to check your air conditioners and what to do if you find out there is already a breeding spree inside. 

Why Mould Grows in Air Conditioning Units?

It's all about the environment. Mould is like that uninvited guest who crashes the party because they heard there was free food. In the case of your AC, "free food" is a combo of moisture, darkness, and organic material.

Now, think about how an AC works. It pulls in warm air, cools it down, and then sends it back out. In this process, condensation happens, creating moisture. Pair that with the naturally dark interiors of the unit and any dust or organic particles that get trapped inside, and voilà! You've set the perfect stage for mould to waltz in and make itself at home. It's not that your AC is doing anything wrong; it's just that its regular function inadvertently rolls out the red carpet for these pesky intruders.


Tell-tale Signs of Mould in Your Air Conditioning Unit

Tell-tale Signs of Mould in Your Air Conditioning Unit

Unpleasant Odour

Have you ever walked into a room and been hit by a musty, old library-book smell? That's not the scent of ancient wisdom; it's probably mould. This distinct aroma isn't just unpleasant; it's a red flag. When mold sets up shop in your air conditioner, it needs to be more content with staying put. As your air-con unit blows out cool air, it can also carry that musty scent, spreading the tell-tale odour throughout your living space. So, if your home suddenly smells like grandma's attic, it might be time to give that AC a closer look.

Visible Mould Growth

Now, if you're the hands-on type and decide to pop open your AC unit, there are a few spots you'll want to zero in on. Look for suspicious patches on the coils, lurking in the drain pan, or hiding within the ducts. But here's the tricky part: not every dark or fuzzy spot is mould. Regular dirt or dust can sometimes masquerade as mold. The key difference? Mould often has a fuzzy or slimy appearance, while dirt is just... well, dirt.

Allergic Reactions or Respiratory Issues 

If you or your family members are suddenly channelling their inner allergy commercial—think sneezing, coughing, or watery eyes—it might not just be pollen season. Mould spores from your AC can irritate the respiratory system, leading to these symptoms. So, if you're reaching for tissues more often and there's that musty smell in the air, mold might be the uninvited guest causing the ruckus.

Reduced Airflow and Efficiency

Ever felt like your AC's just not blowing as strong as it used to? Mould might be hogging the limelight. As it grows and spreads, mould can clog essential parts of your unit, making it work overtime. Not only does this mean your home might not cool down as efficiently, but you might also see a spike in your energy bills. And let's be honest, no one's a fan of that.

Frequent AC Malfunctions

If your air conditioning unit has more off days than on, mould might be the sneaky culprit. By invading and growing on crucial components, mould can cause them to wear out or malfunction faster. It's like having a tiny saboteur inside your unit, causing hiccups and breakdowns.


Regular Maintenance and Cleaning of Your Air Conditioner To Prevent Moulds

Filter Swap: Change out or clean your AC filters regularly. A clogged filter is a playground for mould.

Drain Pan Cleaning: Empty and clean the drain pan to prevent water buildup. A bit of white vinegar can help prevent mould growth.

Duct Inspection: Every once in a while, shine a flashlight into your ducts. If you spot any mould or excessive dust, it might be time for a professional cleaning.

Keep It Dry: Ensure your AC's condensation lines are clear, allowing moisture to drain away correctly.

Proper Humidity Control

Dehumidifiers. These handy devices pull excess moisture out of the air, making it harder for mould to grow. Consider getting one if you live in a particularly humid area or have rooms that tend to get damp (basements, anyone?).

But how do you know if you've got a humidity problem? Enter humidity monitors. These little gadgets measure the moisture level in the air. If you see numbers consistently above 60%, it's time to take action.

Lastly, let's talk about your AC's drainage. It's crucial to ensure water drains away from your unit correctly. Regularly check those drainage lines and pans. A little puddle might seem harmless, but stagnant water is a VIP invitation for mold. So, keep things dry, and you'll be on your way to a mould-free AC experience.

What You'll Need

Good ol' white vinegar (nature's germ-buster)

Lukewarm water

A dash of tea tree oil (it's not just for skin; this stuff fights off fungi and bacteria)


Step-by-Step Guide

Blend It: Mix 1 part of your white vinegar with two parts of lukewarm water in a handy spray bottle. Are you feeling fancy? Add about ten drops of tea tree oil for that extra mould-fighting punch.

Safety First: Make sure your aircon's power is off. We're cleaning, not conducting electricity experiments.

Spritz Away: Gently mist the mix onto potential mold hangouts in your AC, like those coils, filters, and the drain tray. Don't drench it; a little goes a long way.

Let It Sit: Give it about a 10-minute break. This lets the vinegar and tea tree duo work their magic.

Scrub It: Wipe any grime or unwanted guests with a clean rag or sponge. Tight spots? A soft brush should do the trick.

Optional Rinse: If the vinegar aroma isn't your jam, give the sprayed areas a light rinse with plain water. But remember, we want it dry, not a swampy mess.

Dry Time: Before you power up, ensure everything's dry. Speed things up with a dry cloth if needed.

Heads Up: Always peek at your aircon's guidebook before cleaning. And if mould's being extra stubborn or you're unsure about something, ring up a pro.
