Will low Freon damage a compressor?

A low Freon charge can lead to compressor damage and overall inefficiencies of the air conditioning unit. This problem happens when the low refrigerant causes freezing on the evaporator coils. Eventually, the ice build-up leads to the insulation of the coils and slows the cooling process.

Does low Freon always mean a leak?

Low refrigerant usually occurs because of leaks along the line or in the compressor. Because refrigerant usually evaporates as it escapes, you won't notice any dripping. Instead, the first sign you'll see of the loss of refrigerant will be frost over the indoor coils.
