Can you mix different types of freon?

In short, the answer is, “No!” Automotive refrigerants are volatile compounds that can have a negative effect on the environment. Combining them can have adverse effects, and cause damage to your car’s A/C system.

Is R134 a HFC?

R134a was the first chlorine free (ODP = 0) HFC refrigerant that was tested comprehensively. It is now used world-wide in many refrigeration and air conditioning units with good results. As well as being used as a pure substance, R134a is also applied as a component of a variety of blends.

Why is R22 illegal?

Since you’re reading this article, you probably know that the former industry-standard R22 refrigerant (also known as Freon) has been phased out worldwide due to its harmful effects on the ozone layer.

Can you put R410A in a R22 system?

No, you cannot. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system.
