GWP stands for Global Warming Potential, a relative measure of how much heat a greenhouse gas traps in the atmosphere compared to Carbon Dioxide. In the HVAC industry, GWP is used to evaluate the environmental impact of different refrigerants. Older refrigerants had very high GWP, whereas our newer R454B Wall Mount systems use gases with significantly lower ratings. By reducing the GWP of our units, OLMO is actively participating in the global "Decarbonization" movement. This is an important metric for homeowners looking to reduce their "Carbon Footprint" while maintaining high-efficiency cooling. Many upcoming regulations specifically target high-GWP refrigerants, making our Single-Zone R454B models a future-proof investment. We provide clear documentation on the GWP of all our Multi-Zone units to help you make an eco-conscious choice. Reducing GWP is a key step in creating a more sustainable and environmentally friendly HVAC landscape.
