What are the most common air conditioning duct problems?

Air conditioning problems don’t end with the air conditioner unit itself. They can also occur with ductwork. You might have leaking ducts, poorly sealed registers and grills, damaged flexible ducts, poorly insulated ducts, or even dirty ducts! All of this can lead to an overworked, inefficient cooling system that means a higher energy bill for you and an AC that may conk out before its time.
