Is your home’s HVAC system emitting odd noises? Unusual sounds from your HVAC system can sometimes signal a significant issue with your equipment. Recognizing these sounds and their potential implications is crucial to address them promptly and avoid further damage.

Alarming Sounds and Their Possible Causes:

1. Banging

4. Rattling
