How much does the new refrigerant cost?
Although R-410a costs a little more to make than R-22, the price is expected to decline as it is produced in higher volumes. Additionally, the cost of R-22 is expected to increase as supplies become tighter. The higher cost of R-410a systems at this point are mostly due to the investment the manufacturers made in system redesign and the investment that installers make in tools and training. One cooling equipment manufacturer wholesales the R-410a unit at a premium of $150 over an equivalent SEER R-22 system.
