A/C System Mandate: What It Means for Your Home and Budget
Starting January 1, 2025, the EPA mandated that new air conditioning and heat pump systems must not use high-GWP (Global Warming Potential) refrigerants like R-410A. While this may sound technical, the changes affect real-world things like system costs, insurance, and your monthly energy bills. Here’s what Houston homeowners should know, and how to prepare.
What’s Behind the Mandate
R-410A, this refrigerant is the chemical that flows inside your air conditioning system to absorb heat from inside your home and release it outside, keeping your home cool. You may know the older types by their trade names: Freon (phased out in 2010 for damaging the ozone layer) and Puron (R-410A), the current standard.
Under the new rules, systems must comply with a GWP limit of about 700 or lower, ushering in the era of A2L refrigerants, specifically R-454B and R-32. These newer refrigerants are more eco-friendly but mildly flammable, requiring updated safety features in new systems.
Why Is This Happening?
This mandate is part of a broader effort under the American Innovation and Manufacturing (AIM) Act and the global initiative to combat climate change. Enacted in 2020, the AIM Act empowers the EPA to phase down hydrofluorocarbons (HFCs); potent greenhouse gases widely used in air conditioning, refrigeration, and more. The goal is an 85% reduction in HFC production and consumption by 2036.
