While a fully operational AC unit should not lose any Freon, a typical unit that requires servicing and maintenance can, even without a visible sign of a leak.
What causes AC to lose Freon? 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.
