What is the most common source of refrigerant leaks?
The most common cause of AC freon leaks is likely erosion of the metal over time due to formic acid or formaldehyde corrosion. Small holes are formed when the acid eats away at the metal and the unit eventually releases freon.
How do I know if I have a refrigerant leak?
