Vital Modifications to Air Conditioning Refrigerants in 2025


The life blood of your air conditioner is refrigerant. Because it circulates by means of your system, it transitions from a low-pressure gasoline to a high-pressure liquid. Throughout this course of, it absorbs warmth after which releases it, contributing to cooling the air that’s distributed all through your property.

R22

For many years, R22 was the gold normal of house air con refrigerant. Developed within the Nineteen Thirties, R22 is a hydrochlorofluorocarbon (HCFC) that was later found by scientists to be dangerous to Earth’s ozone layer. Within the Nineteen Eighties, the Environmental Safety Company (EPA) and world our bodies established the Montreal Protocol to eradicate the usage of ozone-depleting refrigerants. Starting in 2003, incremental restrictions on R22 had been carried out to cut back manufacturing and block importation. By early 2010, the manufacture of R22-based tools was completely prohibited in the US.

R410A

As R22 was phased out, R410A emerged as its substitute. At the moment, most house air con items, together with many put in because the late 90s, use R410A refrigerant. Not like R22, R410A is a hydrofluorocarbon (HFC) and accommodates no chlorine, giving it an ozone-depleting potential (ODP) rating of zero.

R410A excels in absorbing and dissipating warmth, making it extra vitality environment friendly than R22. Its superior temperature adaptability additionally ensures faster heating or cooling of your property or workplace.

Sadly, as within the case of R22, R410A’s reign because the refrigerant normal should additionally come to an finish.

Like R22, R410A has excessive world warming potential (GWP). Actually, R410A’s GWP is 2,088 which is barely greater than R22’s GWP of 1,810.

To curb the usage of high-GWP refrigerants in HVAC programs, the EPA has intervened once more and enacted a sequence of rules by means of the American Innovation and Manufacturing (AIM) Act. Starting January 1, 2025, residential and lightweight industrial air con merchandise using R410A will not be allowed for import into the US.

Subsequent phases of the AIM act contain progressively eliminating R410A from present programs, a course of anticipated to unfold over the subsequent a number of years.

R410A Section Out Timeline

  • 2022 – HCF manufacturing decreased by 10%
  • 2024 – HCF manufacturing decreased by 40%
  • 2029 – HCF manufacturing decreased by 70%
  • 2034 – HCF manufacturing decreased by 80%
  • 2036 – HCF manufacturing decreased by 85%

R32 and R454B

With R410A going the way in which of R22, the brand new normal refrigerant contenders are A2L-class refrigerants R32 and R454B.
