Glycol Leak vs Condensation Leak

Glycol Leak

A glycol leak occurs when the system's glycol loop, which is a closed-loop system that circulates a mixture of water and antifreeze, develops a leak.

The source of the leak would most likely be coming from a connection within the loop, such as an inlet/outlet hose and shut off valve, or small parts such as an actuator or cartridge.

Condensation Leak

Condensation occurs when a system is used in cooling mode and moisture from the air condenses on the evaporator coil which drips down into the condensate drain pan.

The leak could be caused by a clogged drain pan and the drain line being blocked with debris. The condensation would fill the pan and overflow into the surrounding area. In this case, an HVAC technician or a certified plumber would need to clear the drain line to allow the water to flow freely again.

It is important to address both types of leaks promptly to prevent damage to the system, building finishes, and other materials. If you suspect that your system is experiencing a leak, it is recommended to contact a qualified HVAC technician for inspection and repair.
