The 404a costs around $78. the 407F costs around$150. but you don't have to change the expansion valve, it works with the existing R22 valve. I expect the cost to eventually drop as it becomes more popular. I do like 404a, but 407F 's pressures are the same as R22 and it's good. Whats happening is they put numbers to all the refrigerants, GWP, global warming potential, the limit is 4000, R404a is 3950, too close and they want to drop the limit lower,. R407F has a GWP of somewhere around 2700 so it's safe for now. That's the latest coolaid.
