Why does my car aircon system run low on refrigerant ?
A. A/C systems will tend to lose refrigerant over time as refrigerant permeates through the physical joints between components. In normal working conditions all automotive air conditioning systems will lose about 10% to 15% of refrigerant each year which is considered natural leakage. Letting the system run low on refrigerant and the compressor lubricating oil that is suspended in the gas can lead to wear and even serious component failure.
