Got a Musty Smell from Your Air Con? Here’s Why (and How to Fix It)

1. Let’s Talk Weather

It’s a typical cloudy Monday here on the Central Coast – overcast skies and sitting around 19 degrees. Not cold, not hot… just that sticky, damp air that makes everything feel a little clammy.

2. The Problem: That Musty Air Con Smell

This type of weather can lead to a common (and gross) issue in split systems: the wet sock smell. Moisture can sit on the internal coils, especially if the unit hasn’t been serviced in a while. Over time, bacteria and mould grow, causing that distinctive musty odour when you switch the system on.

This isn’t just unpleasant – it can also impact air quality, especially for anyone with allergies or asthma.

3. The Solution: A Deep Clean from the Experts

At My Air Con Care, we don’t just wipe your unit and call it a day. We use specialised cleaning tools like high-pressure catchment bags to flush out gunk, bacteria, and grime from deep inside the system – especially the areas prone to moisture build-up.

If your unit’s starting to whiff or airflow feels a little off, give us a bell. We’re locals right here in Wamberal and happy to swing by Terrigal, Erina, or wherever you need us. No pressure – just good honest service.

Stay fresh,
Jason from My Air Con Care
