When the refrigerant in your air conditioner is low, it will cause the evaporator coil to freeze over. When the coils thaw, the water overflows in the drain pan. If the refrigerant leak is significant, the entire AC system may need to be replaced. Contact A+ immediately if you believe your refrigerant is leaking.

Why is there water dripping from my AC vent?

Dirty Air Filters
Instead of dripping condensation drops into the drip pan, the water will freeze over the AC’s evaporator coils, forming a thin layer of ice. The longer you keep the dirty filters, the thicker the layer of ice becomes. This ice will start dripping as it melts, causing the water to drip from your vents.
