• Compressor: The heart of your AC unit, the compressor is responsible for compressing the refrigerant, which circulates throughout the system and absorbs heat from your home. It’s one of the loudest components, and any issues here can lead to significant noise.
• Fan Motors: Both the indoor and outdoor units have fan motors. The indoor fan circulates cool air throughout your home, while the outdoor fan dissipates heat. These motors can become noisy due to wear and tear or debris buildup.
• Refrigerant Lines: These lines carry the refrigerant. Issues like leaks or restrictions can cause hissing, bubbling, or rattling sounds.
• Ductwork: If your AC uses ductwork, problems within the ducts, such as leaks or improper insulation, can amplify noise or create new sounds.
• Other Components: Other parts, such as the blower wheel, capacitors, and relays, can also contribute to noise if they malfunction.
