Lennox is The Latest US Manufacturer to Switch All Residential HVAC Devices to Reduced GWP Refrigerant R454B.
Updated: May 14
USA: All of Lennox's residential HVAC devices will now use the lower GWP refrigerant R454B, making the company the latest US manufacturer to make this announcement.
The new R454B residential line from Lennox will consist of air conditioning units and heat generators. R454B will be integrated into the entire lineup of commercial rooftop units and ducted split systems, including the acclaimed Model L and Enlight RTUs. Additionally, the products will incorporate leak detection technology. Advanced Distributor Products, a division of Lennox, introduced a multi-refrigerant coil earlier this year to assist HVAC contractors and distributors in the switch from R410A to any low GWP refrigerant.
