What Homeowners Should Know About Low-GWP Refrigerants And Upcoming Regulations
As the HVAC industry evolves, new regulations and technologies are shaping how heating and cooling systems operate. One of the biggest changes homeowners may hear about involves low–global warming potential (low-GWP) refrigerants. These refrigerants are part of a nationwide effort to reduce environmental impact while maintaining reliable indoor comfort. What Are Low-GWP Refrigerants? Refrigerants are the substances inside air conditioners and heat pumps that absorb and release heat, allowing your system to cool your home. Low-GWP refrigerants are designed to reduce their effect on climate change. “GWP,” or global warming potential, measures how much heat a refrigerant can trap in the atmosphere compared to carbon dioxide. The lower the number, the less environmental impact it has. Why Regulations Are Changing Federal regulations are driving the shift toward more environmentally friendly refrigerants. These policies aim to gradually phase down refrigerants with higher GWP and replace them with more sustainable alternatives. Beginning in the next phase of these regulations, many newly manufactured air conditioning and heat pump systems will use newer low-GWP refrigerants instead of older options. This change applies mainly to new equipment, not systems that are already installed in homes. What This Means For Your Current HVAC System If your...
