In 2013, the freon landscape varied by application, with R-134a as the dominant refrigerant in automotive air conditioning; older systems still relied on R-12 or R-22, while some new cars began using the lower-GWP option R-1234yf.
Freon usage by sector in 2013
The following overview highlights which refrigerants were most common across major sectors in 2013 and how the market was transitioning away from older substances.
- Automotive air conditioning: R-134a was the standard refrigerant in the vast majority of cars sold in 2013.
- Emerging low-GWP option: R-1234yf began appearing in a growing share of new vehicles as a lower-GWP alternative to R-134a.
- Residential air conditioning and heat pumps: R-410A had replaced older R-22 in new equipment.
- Commercial refrigeration: R-404A was widely used in supermarkets, cold storage, and other large-scale refrigeration systems.
- Legacy systems and servicing: R-12 and R-22 persisted in older equipment and in servicing of those systems, but their use was increasingly restricted by international and national regulations.
Concluding: By the end of 2013, the refrigerant mix reflected sector-specific standards and ongoing phaseouts, with R-134a dominating automotive A/C, R-410A in new residential units, R-404A in commercial refrigeration, and continued but shrinking use of R-12/R-22 in legacy equipment.
Context and regulatory backdrop
To understand the shift, it's important to note the regulatory environment driving change. The Montreal Protocol targeted ozone-depleting substances like R-12 and R-22, while separate regulations and industry efforts pushed for lower global-warming-potential (GWP) refrigerants, accelerating the adoption of options like R-1234yf in new vehicles.
Timeline snapshot
Key milestones around that period help explain the 2013 landscape:
- Late 1990s to early 2000s: R-134a becomes the standard automotive refrigerant as R-12 is phased out for new equipment.
- Early to mid-2010s: R-410A replaces R-22 in new residential air conditioning; R-404A remains common in commercial refrigeration.
- Around 2013 onward: R-1234yf begins to appear in some new cars as a low-GWP alternative to R-134a, with broader adoption in subsequent years.
Concluding: The 2013 period marks a transitional phase, with the automotive sector leaning toward R-134a but gradually expanding the use of R-1234yf, while other sectors continued to adopt or upgrade to R-410A and R-404A in line with regulatory and market pressures.
Summary
In 2013, R-134a was the prevailing freon for automotive air conditioning, R-410A led in new residential systems, and R-404A dominated commercial refrigeration. R-12 and R-22 lingered only in older equipment, as regulators and manufacturers began a broader shift toward lower-GWP refrigerants such as R-1234yf in some newer vehicles and other sector reforms.
