Here are a few ways to tell:

1. Check for soot around the unit: If there is a black buildup of soot, this could be an indication that your AC is leaking carbon monoxide.

2. Pay attention to any strange smells coming from the unit: Carbon monoxide is odorless, but if there are other gases present, they may produce a smell.

3. Be Aware: Be alert of any symptoms that you or others in your home may experience when near the AC unit. These could include headaches, dizziness, nausea and vomiting, shortness of breath, and fatigue.

If anyone experiences these symptoms and they go away when they leave the area near the AC unit, it’s possible that carbon monoxide poisoning is occurring.
