Refrigerant Update for Residential Clients in Cumming, GA: 2025 HVAC Low GWP Transition

As technology advances, so do the regulations that come with it. Your heating, cooling, and air conditioning (HVAC) system is no exception. As of 2025, there are new regulations in place to update the type of refrigerant used in residential and commercial HVAC systems, chillers, and related equipment that use refrigerant. Here at Kennon Heating & Air Conditioning, we’re here to help you understand why these changes were made and how this impacts homeowners in the Cumming, Georgia, region when they need an emergency HVAC repair.

Understanding the Role Refrigerant Plays in HVAC Systems

Refrigerant is a type of chemical used to create the cooling effect in HVAC systems and other cooling appliances. These chemicals are not the most environmentally friendly materials, however. High-GWP refrigerants, such as the commonly used R-410A, are a big source of hydrofluorocarbons (HFCs), a type of greenhouse gas that’s harmful to the environment. This is why the Environmental Protection Agency (EPA) recently mandated a change to use low-global warming potential (GWP) refrigerants.

What Changes Were Made to Refrigerant Requirements in 2025?

Based on the aggressive EPA mandate introduced in 2024, manufacturers of HVAC systems had to switch to a refrigerant with a GWP of 700 or less by January 1, 2025. Many HVAC manufacturers chose to use options like R-4545B or R-32. These low-GWP refrigerants allow for:

• More robust cooling capacity
• Precise temperature control
• Less atmospheric heat-trapping
• Advancement of sustainability goals

What Does This Mean for You?

Today, a number of low-GWP refrigerants are available, allowing for better options for your HVAC system. What this means is that if you need an HVAC repair or decide to replace your HVAC system, you’ll be dealing with low-GWP refrigerants. This won’t affect you in a negative way—in fact, it will hopefully lead to the heating and cooling industry being more considerate about their business practices and, thus, a lower carbon footprint for humanity. These low-GWP refrigerants are used just like the old ones, so the effectiveness of these units will be similar to what you’re used to, if not better.
