Help needed: S76A+ Air conditioning question
 

I am trying to help out my chief engineer. We have a 76A+ with an Air Con system on board that still uses the old Freon 12. While I know that this is a difficult substance to buy now and was banned by the EPA due to its ozone depleting characteristics, I need some help in building an argument to a customer who owns the A/C and doesn't want to convert it to a more environmentally friendly substance.

some points in favour of changing refrigerants:

Freon:
High Cost / decreasing Availability / Environmentally damaging/ Leakage (I understand that a fully recharged system will bleed refrigerant).

Anything else?

Thanks in advance

Every time he asks for the aircon to be switched on, tell him it already IS on.

If it still works, leave it.
