Can you put R 134a in an R12 system?

Can you put R 134a in an R12 system?

To be able to use R134a in an R12 system, the R12 system needs to undergo a retrofitting so that it’s able to handle and process R134a refrigerant. This also means that some refrigerant conversion needs to be done in order to drop R134a into a R12 system.

How much does it cost to convert from R12 to R134a?

It will generally cost you about $200 to have a mechanic convert an AC system for you. If you want to replace a vehicle’s AC system, it will cost between $1,500 and $4,000 with an average cost of $2,750. If you decide to have a professional work on your car, you will have several options for where to get the work done.

Is 134a the same as R12?

R12 and 134a are refrigerants used in car air conditioning systems. R12 was used in most cars and trucks until 1995 when it was replaced with 134a. The main difference between the two is that R12 is the amount of time they remain in earth’s atmosphere, with the newer 134a significantly less than the old R12.

What is R12 refrigerant used for?

R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.

Is R12 toxic?

Dichlorodifluoromethane (alias of R 12 (refrigerant)) A) Freons are very toxic when inhaled in high concentrations and/or for extended periods. At lower concentrations or brief exposure, freons may cause transient eye, nose, and throat irritation.

Is there a direct replacement for R12?

The best replacement for R12 is considered to be R-134a. The chemical name of R134a is tetrafluoroethane and it chemical formula is CF3CH2F.

Why is R12 bad?

Conclusion. In conclusion folks R-12 Freon was banned due to the damage that it caused to the Ozone layer. The Chlorine found in CFC refrigerants like R-12 would not break down in the atmosphere when vented or leaked. The Chlorine would then erode the Ozone bit by bit.

What happens when you convert a R12 to are 134a?

In order to do the same job, an R-134a system will need a larger compressor and larger heat exchangers. As a result, a system that is retrofitted from R-12 to R-134a will have lower capacity (run longer) and will probably develop higher head pressures (not enough condenser area). The lubricant will also need to be flushed and replaced with POE.

How to retrofit a R12 system to a R134a?

3) R134a retrofit kit with R-134a port adapters, oi, port caps and retrofit label 1) Discharge the R12 and recover the R12 for recycling. 5) Add specified Ester or PAG oil in the proper viscosity to the compressor, condenser and evaporator.

Which is better R12 or R134A cooling system?

Since R134a is LIGHTER than R12, you must convert the charge weight to get the proper charge during your retrofit. Fill the system with 75 to 85% of the factory specified capacity to achieve the best cooling. Use this formula or the chart below.

Can a Mopar classic be converted to R134a?

Whether you need to convert a Ford, GM, or MOPAR classic from R12 to R134a, two helpful tips to keep in mind…. Ignore your sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass. Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.
