The information via https://www.melaniejadedesign.com/refrigerant-changes/ about the 2025 refrigerant changes is concise and helpful for homeowners looking to understand upcoming HVAC regulations. The site explains the shift from R-22 and R-410A to eco-friendlier refrigerants like R-454B and R-32, aligning with global efforts to reduce carbon emissions per EPA guidelines. It highlights that existing systems don’t need immediate replacement but notes potential maintenance cost increases due to the phasing out of older refrigerants. While the page offers a solid overview, I’d have liked more practical tips, like cost estimates or specific steps for transitioning. Still, it’s an accessible introduction to a complex topic, ideal for those preparing for the 2025 changes.
