Environmentally Friendly

When you purchase GrandAire® products, you are making an investment in your home and your environment. GrandAire along with ICP and the whole Carrier family of products is moving to a new refrigerant. New for 2025 and beyond GrandAire will be using R-454B the lowest GWP (Globel Warming Potential) and Non-ozone depleting refrigerant on the market to date. The utilization of R-454B refrigerant is in line with our legacy of dedication to environmental stewardship. This refrigerant achieves a remarkable 75% reduction in Global warming potential while preserving the non-ozone depleting properties of our previous refrigerant 410A.
