Refrigerant leaks can be easy to miss, and you may only notice them when your air conditioner develops a problem. To catch leaks early, call a professional when you see signs of a leak such as hissing sounds or oily spots, frozen coils, ice-up refrigerant lines, poor cooling performance, or warm air from the vents.
