The primary advantage of using R-410A refrigerant over R-22 is its higher energy efficiency. R-410A operates at a higher pressure than R-22, allowing for improved heat transfer capabilities. This results in better cooling performance and energy consumption efficiency, which translates to lower energy bills for consumers.

Furthermore, the higher energy efficiency of R-410A contributes to a reduction in environmental impact, as more efficient systems typically have lower greenhouse gas emissions associated with their operation. This characteristic becomes particularly significant when considering regulations aimed at phasing out R-22 due to its ozone-depleting potential and the environmental concerns associated with its global warming potential.

R-22 is being phased out largely because of these concerns, and as a result, R-410A is also favored not just for efficiency but because it is more compatible with modern HVAC system designs that prioritize higher performance and lower environmental impact.
