Causes of Air Con Smell
Air con smell can be a real nuisance, and it's often a sign of a bigger issue. Dirty or clogged filters are a common culprit, as they can introduce unwanted smells into your air conditioner.

Animals, insects, or rodents can also leave behind odors that get trapped on your AC's coils. This can be a real problem if you have a rodent infestation in your roof cavity.

Troubleshooting and Diagnosis
The smell of air conditioning can be a real nuisance, but don't worry, we've got some troubleshooting tips to help you figure out what's causing it.
First, check your air filter - if it's dirty, it can harbor bacteria and mold that produce unpleasant odors. A clogged filter can also reduce airflow, making the smell worse.
