Is the chill from your air conditioner feeling unexpectedly warm? No need to panic! Dive deep into this detailed guide to uncover common causes for this issue and find actionable solutions.

 

Dirty Air Filter: A Common Culprit

A clogged air filter is one prevalent reason for an AC emitting warm air. As days pass, dust and other particles gather on the filter, limiting the airflow and thus affecting the AC's cooling efficiency.

Good news? You can often handle this on your own:
