Understanding the Source of the Smell
The first step in solving any problem is understanding its root cause. When it comes to bad smells from an air conditioning system, several factors could be at play. Identifying the specific source of the odor is crucial for effective troubleshooting.
Common Causes of Bad Smells
There are several reasons why your AC unit might emit unpleasant odors. Some common causes include:
