At some point during the summer when your air conditioning is running on a regular basis, you may notice ice developing along its indoor evaporator coil. At first, this may not seem like it’s a major problem. After all, doesn’t the presence of ice mean that the air conditioner is doing its job of lowering the temperature?
However, ice should never appear on an air conditioner when it’s running correctly. ACs don’t use ice to lower the temperature of the air sent into the ventilation system, and the presence of ice means that a malfunction is causing the evaporator coil to stayed colder than it should be, triggering moisture along it to freeze. Call for HVAC repair technicians when you see this occurring so you can have the problem fixed before it affects your comfort—or damages the air conditioner.
