R-32 is an environmentally friendly refrigerant, part of the industry's shift to reduce greenhouse gas emissions in HVAC systems.

What is R-32 Refrigerant?

R-32, also known as difluoromethane, is a hydrofluorocarbon (HFC) refrigerant with a low global warming potential (GWP) and zero ozone depletion potential (ODP). This makes it a more sustainable option compared to older refrigerants like R-22, which has a high GWP and contributes to environmental harm.

Why is R-32 More Efficient?

R-32 is known for its energy efficiency, which can result in both cost savings and reduced carbon emissions. With a lower environmental impact and increased efficiency, it offers benefits to both homeowners and the planet.

The Refrigerant Transition and AIM Act

Under the American Innovation and Manufacturing (AIM) Act of 2020, the Environmental Protection Agency (EPA) began phasing down the production and consumption of high-GWP HFCs, including those used in cooling equipment. This process started in 2022 and aims to reduce emissions over time, ultimately reaching a 15% production limit by 2036.

In response to this mandate, many HVAC companies are moving toward R-32 and other low-GWP refrigerants, such as R-454B, in a gradual shift to improve sustainability across the industry.

Determining the Type of Refrigerant in Your System

Your HVAC system’s owner’s manual will specify the refrigerant type. If you don’t have access to the manual, contact your HVAC service provider for details. They can identify your system’s refrigerant and recommend any necessary steps for future compatibility.

Using Older Refrigerants

If your system still operates on R-22 or R-410A, you can continue using it for now. The EPA’s phaseout schedule allows homeowners time to transition to eco-friendly options as systems age or require replacement. While reclaimed R-22 supplies are declining, R-410A is expected to be available for maintenance for several more years.

Transitioning to lower-GWP refrigerants like R-32 supports environmental goals while enhancing cooling efficiency.
