Mould thrives in a moist environment and air conditioners provide the perfect conditions for mould and mildew to grow. Air conditioners rely on the outside air being sucked into the air conditioning unit and cooled. That air is full of airborne bacteria and mould spores. When an air conditioner is at rest, its interior warms up and any residual moisture and condensation within the unit and its ducting creates ideal conditions for mould to thrive.

Why Is Mould In Your AC a Problem?

Mould spores are the mechanism through which mould reproduces. When your air conditioning unit is at rest, it’s the perfect petri dish for a wayward mould spore to grow on. Once comfortably at home in your air conditioner, mould spores will be released and become airborne. They’ll spread throughout your home, landing on your food, your clothes and where you’ll eat them and breathe them in. If you have an allergic sensitivity to mould, its presence in your air conditioner is likely to trigger a significant reaction.

Mould Causes Blockages

Mould, when left long enough, can also cause significant problems that will affect the efficiency of your air conditioner. In some instances, a build-up of mould can even lead to blockages within the air conditioning drains. The end result can be an expensive and inconvenient breakdown when you need your cooling system the most.

Signs of Mould in Your Air Conditioner

Chances are you might not see any visible signs of mould to start with. The first sign you might have of a mouldy air conditioner is a musty or funky smell when it’s in operation. If you’ve eliminated all other potential suspects as the source of the smell, you need to turn your attention to your air conditioner.

Once a mould colony is established you might notice tell-tale black or grey circular marks (mould deposits) on the interior surfaces of your air conditioner. Worse still, you might see evidence of mould spreading to your walls and ceiling.

If you suspect you’ve got a mould problem, you can arrange for a professional to clean your air conditioner.
