Visual and Physical Check






Visual and physical check

Large and slow leaks will often result in air conditioning (A/C) compressor oil being drawn out with the refrigerant.
A visual inspection can localize the point where the oil gathers and identify the source of the leak.
- Check the system for corrosion which could cause refrigerant to leak
- Check that there are no loose components.
