Having too much refrigerant in your AC can damage the compressor.

Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.

Will low Freon damage a compressor?

Low refrigerant also damages the compressor, the “heart” of the air conditioner where the liquid refrigerant is squeezed into a high pressure gas. The compressor is designed to match the refrigerant charge, and if it drops, the compressor will start to overwork and will soon break.
