A persistent bad odor from your AC doesn’t always mean it needs to be replaced, but it does indicate an issue that requires attention. Common causes include mold or mildew buildup, which can often be resolved by cleaning filters, coils, and drain lines, or burning smells, which may signal an electrical issue needing immediate inspection.

Musty odors are usually due to dirty filters or ductwork and can be fixed with regular maintenance. However, if odors persist despite cleaning and repairs, it could point to severe mold growth, failing components, or an aging unit (15+ years old).
