Why does my AC furnace keep freezing?
Improper refrigerant fluid levels can also cause an HVAC unit to freeze up. When the refrigerant is low, the coils will be too cold, causing them to freeze. Be aware that if your refrigerant levels cause the unit to freeze up, your coils can become damaged, which can then damage the compressor.
Can a bad capacitor cause AC to freeze?

A frozen AC will either blow warm/cool air or nothing at all.
