   • Characteristics: The smell is usually temporary and dissipates after a short period of operation. It often smells like burning dust or a hot electrical appliance.
   • Severity: Typically, this is a minor issue that resolves itself. However, excessive dust accumulation can reduce the efficiency of the AC and potentially lead to other problems.

   • Description: While refrigerant itself doesn’t typically have a strong odor, a refrigerant leak can sometimes cause a burning smell due to the compressor working harder to compensate for the loss of refrigerant. Additionally, the oil used to lubricate the compressor can leak along with the refrigerant, producing a burning smell when it comes into contact with hot components.
   • Characteristics: The smell might be faint and difficult to identify. You might also notice a decrease in cooling performance or ice forming on the AC unit’s coils.
