How to Identify and Repair an AC Discharge Hose Leak

AvatarByCarl Frisch

An AC discharge hose leak is a common problem in air conditioning systems. This type of leak occurs when the hose that carries the refrigerant from the compressor to the condenser becomes worn or damaged, resulting in a leak. The most common symptom of this type of leak is an increase in temperature and humidity levels inside the vehicle cabin. If not addressed, this can lead to a decrease in cooling performance and an increase in fuel consumption. To address this issue, an experienced technician should be called to inspect and repair the leak promptly. The replacement of the damaged hose with a new one is usually necessary to help restore proper cooling performance and reduce fuel consumption.
