What’s the Difference Between R-22 and R-410A?

One of the hottest discussions within the air conditioning and heating industry is the difference between two refrigerators – R-22 and R-410A. Considering a buyer as a buyer, it is important that you understand the difference so that you can make the best decisions for your system. We are mentioned below with the main difference and why they matter.


  • Often referred to by a brand name like Freon®
  • As of 2010, R-22 was discontinued for use in new air conditioning systems
  • R-22 is a hydrochlorofluorocarbon (HCFC) which contributes to ozone depletion


  • Often referred to by a brand name like Puron®
  • Has been approved for use in new residential air conditioners
  • Is a hydro-fluorocarbon (HFC) which does not contribute to ozone depletion
  • Will become the new standard for U.S. residential air conditioning systems in 2015

Performance difference

New air-conditioning models are designed to be used with R-410A for reliable and more efficient operation. Because R-410A can absorb and release more heat than R-22, your air-conditioning compressor can run coolers, which reduces the risk of compressor burnout due to overheating.

R-410A also operates under more pressure than R-22, so new compressors are designed to withstand more stress, which reduces the possibility of breakdown. If you put the R-410A refrigerant into a system designed for R-22, the pressure will be high and the unit will break.

All air conditioners use an oil to keep the compressor lubricated during operation. R-22 air conditioners use mineral oil and R-410A systems use synthetic oil. Synthetic oil is usually more soluble with R-22A with R-410A. This means that the R-410A system operates on the compressor to reduce wear and tear more efficiently.

Dry charging

For use in new units, R-22 was declared illegal in 2010, but some companies are taking advantage of the law, which is known as ‘dry charge’ units. These are new units which are not refrigerators installed in the factory. Instead, a technician needs to come out of your home and install R-22 refrigerant. Although this practice is technically legal, it is not the best choice for the following reasons:

There is a limited supply of R-22 and the supply will decrease if the supply is low
R-410A provides more efficiency, which saves you energy costs, and is much better for the environment
Dry charging units usually provide very little warranty period
