HVAC Refrigerants Are Changing—Here’s What Utah Homeowners Need to Know

Phasing Out R-410A: What It Means for Your AC System and Services in Utah Valley

The heating and cooling industry is undergoing a major transformation due to new federal legislation. As part of the American Innovation and Manufacturing (AIM) Act of 2020, manufacturers are being required to reduce their use of hydrofluorocarbons (HFCs)—including the widely used refrigerant R-410A. The goal is to minimize the environmental impact of air conditioning systems by transitioning to eco-friendlier alternatives.

So, what does this mean for your current HVAC system? And how will these changes affect future installations and repairs? The home comfort specialists at Eco Home are here to break it down.

The Transition to Low-Impact Refrigerants

The summer of 2024 marks a turning point in how refrigerants are used in residential HVAC systems. Production of R-410A has already been reduced by 40%, driving up prices and making it more costly to maintain systems that rely on it. As of January 1, 2025, manufacturers will be required to produce new HVAC units that utilize A2L-class refrigerants—a category of refrigerants with significantly lower global warming potential.

While homeowners won’t be forced to replace working systems right away, the supply of R-410A will become increasingly scarce, making repairs and refills more expensive over time.

Why Is R-410A Being Phased Out?

R-410A has been a standard refrigerant in most AC systems for years, replacing R-22 when it was phased out for depleting the ozone layer. However, R-410A itself has been found to contribute to climate change due to its high global warming potential. In response, the EPA released new guidelines in 2021 outlining a gradual reduction in its use and promoting alternatives like A2L refrigerants.

This isn’t the HVAC industry’s first adjustment to environmental regulations, and it likely won’t be the last. Fortunately, technological advancements are keeping pace, offering systems that are both more efficient and environmentally responsible.

What Makes A2L Refrigerants Different?

A2L refrigerants are non-toxic like their predecessors, but they come with one key difference: they’re classified as mildly flammable. This might sound concerning, but rest assured—modern AC systems using these refrigerants are rigorously designed and tested to ensure safety and compliance with all standards. If your system is professionally installed, you have nothing to worry about.

How to Identify the Refrigerant in Your AC System

If you’re unsure which refrigerant your system uses, you can usually find that information on a label attached to the outdoor condenser unit or in your owner’s manual. Still not sure? Contact the experts at Eco Home, and we’ll help you determine your refrigerant type and system age.

Here’s a quick guide:

  • R-410A – The most common refrigerant in units installed after 2010.

  • R-32 – A newer, more eco-friendly A2L refrigerant found in some high-efficiency models.

  • R-22 – Used in systems installed before 2010. Now banned due to ozone depletion.

  • R-134a – Rarely found in homes; mostly used in automotive air conditioning.

  • R-454B – A newer, more eco-friendly A2L refrigerant frequently found in high efficient systems and heat pumps.

If Your AC Was Installed Before 2010…

Your system likely uses R-22, which has been fully phased out. Replacement refrigerant is costly and difficult to find. It may be time to consider upgrading to a new energy-efficient model that uses either R-410A (while it’s still available) or, better yet, a next-gen A2L refrigerant.

If Your AC Was Installed After 2010…

Chances are it uses R-410A, which means you’re not in urgent need of a replacement. However, as the refrigerant becomes more limited, routine service and repairs will likely become more expensive. Proactive planning now can save you money later.
