What refrigerant is used in aircon?
The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.
What are the three most commonly used refrigerants for air conditioning system?
The most common refrigerants used for air conditioning over the years include:
- Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect.
- Hydrochlorofluorocarbons (HCFCs), including R22.
- Hydrofluorocarbons (HFCs), including R410A and R134.
Is it expensive to recharge an R-22 air conditioner?
If your air conditioner uses R-22 refrigerant and the refrigerant leaks, it will be expensive to recharge the system. In the very near future, it will likely become either cost-prohibitive or downright impossible. Manufacturers are also rationing the amount of R-22 refrigerant being sold to HVAC contractors. How can you tell the difference?
When do I need to recharge my air conditioner?
When an air conditioning system loses its ability to cool properly, it may be necessary to recharge the system with new refrigerant. Keep reading for a R-134a A/C pressure chart and steps on how to recharge the A/C system when the system is low on pressure or has been vacuumed out following a repair.

How often should my air conditioner need a freon charge?
Never. An AC doesn’t “use up” refrigerant. So you should never need to recharge your air conditioner with more Freon— unless there’s a leak. You pay to put 1-2 pounds in your system (this is called “charging” your AC unit)

How to recharge an A / C system using a rechargin kit?
In this step by step guide we will show you how to recharge the A/C system using a R134a rechargin kit. This method is used to top off an A/C system that has been working fine for 5 or 6 years. Toping off a system that is over 5 years old is normal as long as there are no major leaks or defective compnents.
Can you add R134a refrigerant to an A / C system?
In many cases you can add R134a refrigerant and your system is back to working normal again. In this step by step guide we will show you how to recharge the A/C system using a R134a rechargin kit. This method is used to top off an A/C system that has been working fine for 5 or 6 years.
