I am replacing my NG furnace and air conditioner.

I noticed that many manufacturers of air conditioners give a choice
between R-22 and R-410A.

Which one would be best suited for a new installation? Why aren't they all
switching over to R-410A?

Thanks

Which is best? It depends, but higher efficiencies can be obtained with
R-410A
Which to buy? R-22 will be around for a long time yet. If all you need is a
lower efficiency unit, R-22 is fine.
At this point I would not be afraid to go with either R-22 or R-410A. Buy
the one that best suits your requirements.
