88 Honda Accord, Freeze 12 A/C

Q: I have an '88 Honda Accord and I would like to know if Freeze 12 refrigerant will work in the A/C system without having to evacuate the system first? Any help will be appreciated...... Ralph

A: Whenever changing the type of refrigerant in an automotive A/C system it is highly recommended to evacuate the system first. The reason? Each refrigerant has its own characteristics, though they perform the same job, chemically they're not the same. The ability of the two refrigerants to join and work together is limited. This in itself could create A/C system problems. Also, if you need the A/C system serviced, a repair facility that is not set up to handle Freeze 12 will refuse to work on your A/C system. Why is this? Freeze 12, R-12 and R-134a refrigerants, each require dedicated equipment. Air conditioning equipment is very costly and few repair facilities are willing to invest in the equipment for alternative refrigerants. By installing Freeze 12 you could find that no one will work on your A/C system. My recommendation, convert your vehicle to R-134a. The refrigerant cost is remarkably less, any repair facility that performs A/C work will have the equipment to handle the refrigerant, the refrigerant is used in all cars manufactured today and the conversion kits are not as costly as many believe.
