I want to add central air to my existing forced air furnace. I see
many available kits and it looks pretty straight forward. Any one
done this? Also all the kits, I have seen, use Freon. Any one know of
any that use 134A.

Let, me suggest, this is not a do it yourself project.

Agreed.


Have you done the calculations to determine the size unit you need?
Have you done the calculations and design work to assure your existing air
handling system can handle A/C? Do you know how? I seem to recall that
in
the US you need a license to handle the Freon and need some special
equipment. Got that?

You do, and if you are caught without it, working on your own stuff, one
litttle vent thats seen by the guys that are paid to look for this stuff,
and its a hefty fine...


I don't think any 134A units are available, but I sure could be wrong.
Why are you interested in 134A?


There are none. 134A isnt used at all in central air units. R22, R12 (older
ones) R500(old Carrier crap) R410a(the new R500 ).
The reason he wants 134a is that he can still (currently, probably not for
much longer) buy 134a at Wal-Mart without the proper EPA refrigerant
handling certificate.
