new refrigerant for a/c units?????

I hear there will soon be a new type of refrigerant on the market that in a few years will make the current refrigerant obsolete (like freon) - - and that if I'm buying new 12 SEER condensers now, I should bite the bullet and get this new refrigerant (only available in 14 SEER models) ????? what's the deal? do I have ANY of this correct? doing a 7 unit building in Harlem, NYC - -thanks, Charlie Marcus 917 568 6750 - chazmarcus@aol.com

The new refrigerant is called R-410A. It's the replacement for R-22.

I believe that by 2010 no new A/C units will have R-22 and by 2020 it won't be manufactured anymore.

R-22 only harms the ozone layer if it leaks out of the system, it's a matter of personal preference.

You're ok to still purchase r-22 systems. The 410's are fine though and shouldn't cost that much more.

lets kick it around here. What do you want to put into it and what return. Do you pay the electric??? higher seer will save you money. You can get units with R410a down to a 12seer. Yes they will stop makeing units for R22 but they can make R22 till 2030.
R 22 cost a lot lot less than R410a does right now by a whole lot. Also with R410a its a mix of freons. So lets say you have a leak in a unit.If its over 50% they have to take it all out of the unit in a recovery set up and recharge the unit with all new freon R410a You cant let the old freon in it as it wont be the right mix. SO you cant just add more freon now and then to a 410a set up
If put in right 410a units work real good and is here now for the long run.
So its up too you how to go. Hope this helps .Any more ??? stay in the same post here

i love 410A, i have 3 of those systems in my home


you live in NYC, will not benefit from the advantage of the higher seer and added dehumidification as we do here in the south

i would go 10 SEER R22. just my 2 centavos!
