This is one of the most common misunderstandings people have about air conditioning systems: seeing ice developing along the indoor evaporator coil is normal. Maybe the AC is working a bit too well, but what’s so bad about that?
The truth is much different. You should never see ice forming on the evaporator coil or any other part of an AC. An air conditioner doesn’t use ice to cool the air. It provides cooling by removing heat from the air and moving it outside. However, because people still imagine frost growing inside old freezers, they tend to imagine that ice on an AC isn’t a problem.
So why does ice start to appear on an AC and what does it mean? Below we’ll explain the ice problem and why it usually means you need professional AC service in Indianapolis, IN.
