What is the difference between car AC and home AC?
While a vehicle air conditioning system is made to cool a 6′ x 6′ space, the home air conditioning system is designed to cool an entire house, which could amount to several thousand square feet of living area. While people are away at work, the house has been heating during the warmest periods of the day.
Can a R-12 car be converted to a 134a?
R-12 is no longer used or produced in many countries and remaining quantities have skyrocketed in price. Since then, the industry standard has been R134a, which is an efficient replacement. Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool.

Can a 134a compressor be charged with a R12 hose?
Drain the compressor oil and recharge with 134a compatible (PAG or Ester Oil) oil. This is assuming the compressor is currently functioning correctly. Replace or restore all rubber hoses with barrier hose. Install 134a charge port adapters. Charge with 134a between 70-80% of the original R12 charge amount. Replace any O-rings with 134a compatible.
How to retrofit R12 to R134a by classic auto air?
R12 Recovery – Recover refrigerant from the A/C system using a dedicated R12 recovery device (to SAE J1990). R12 Parts replacement – Remove the components to be replaced as part of the retrofit to R134a, as recommended by the A/C system or vehicle manufacturers guidelines. Add 30-50ml PAO oil to a/c system.

Can a R-12 air conditioner be converted to an R-134a?
Because R-12 is no longer produced in the U.S. Supplies of recycled R-12 still exist, and some R-12 is still brought in from offshore suppliers. But it is hard to find and expensive. That’s why many people simply recharge their older R-12 air conditioning system with R-134a after repairs have been made. R-134a Retrofit Conversion Costs
When did refrigerant retrofit change from R-12 to R-134a?
When the automotive industry made the shift to R-134a back in 1995-1995, they all published Technical Service Bulletins that covered retrofit procedures for their various makes and models. It takes some searching, but these detailed bulletins are still available on the various OEM Technical Service websites, most of which charge a fee to access.
Is it possible to retrofit an R-12 a / C system?
The other approach to retrofit is the “quick and cheap” one. On many 1989 through 1993 vintage vehicles, R-12 A/C systems can be converted by simply recovering any refrigerant that is still in the system, adding POE oil (which is compatible with both types of refrigerant), and recharging to 85 to 90% capacity with R-134a.
