Your Guide to the 2025 HVAC Refrigerant Phase-Out
The Environmental Protection Agency (EPA) mandated that starting January 1st, 2025, only eco-friendly refrigerants will be used in newly manufactured HVAC systems. Here’s what this means to you as a homeowner in the Los Angeles, CA area. The Refrigerants Being Phased Out In 1987, the United Nations finalized a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances. This agreement, known as the Montreal Protocol, targeted substances used in products such as air conditioners, refrigerators, aerosols, and fire extinguishers. The Montreal Protocol’s goal was to mitigate global warming. The ozone layer filters out harmful ultraviolet radiation from the sun, which is known to reduce agricultural productivity, disrupt marine ecosystems, and increase the prevalence of skin cancer and cataracts. The Montreal Protocol was scheduled to be implemented in different stages as technology improved. After the Kigali Amendment was adopted in 2016, the next milestone in this effort was the 2025 HVAC refrigerant phase-out. This phase-out targets hydrofluorocarbons (HFCs), which are powerful greenhouse gases that, while less damaging to the ozone layer than their predecessors, contribute significantly to global warming. The refrigerants affected in this phase-out include R-410A and R-22. Their production, importation,...
