HVAC manufacturing, like any other industry, is always moving forward. New materials are being developed, and new manufacturing techniques are found to be better than the old ones. These changes often have to do with reducing energy use and limiting environmental impact. New materials for AC coils, multi-phase compressors, and variable-speed motors are all recent advances.
Now, in 2025, there’s another change. Thanks to the American Industry and Manufacturing Act of 2020, many less-efficient and environmentally destructive approaches are being phased out.
