usually come with the condenser charged. but the evap and pipes need
to be evacuated. can I rent a vac pump? and also how would i remove
the old freon from exist system for recycle? thks bill


As I recall, according to the AC direct website, you're supposed to call
a
licensed HVAC company to do that kind of work.

I haven't been to that website for quite a while.



Yep, licensed only to handle refrigerant. That's why self service kits
to recharge auto AC have disappeared from shelves in WalMart, Sam Club.
Drums of refrigerant in Sams Club are labeled such that only licensed
individuals can purchase them.


The auto AC stuff is (atleast it was, not sure what the current rules are) a
joke as far as the license goes. YOu go to store , get a booklet and fill
out a test form. Then you get licensed. It is not so much if you know how
to work on the equipment, but to make sure you know what the law is for
discharging freon into the air. YOu must reclaime it if possiable.
Anyting other than a small ammount when you hook up the hoses released into
the air carries a big fine.
For the AC other than cars , there are several classes of licenses. One for
the small appliances, one for the large stuff such as chillers in big
buildings, and another class or two with one being a universal that covers
everything but the car units.
They all cover the laws for handling the refrigerant and not much on how the
AC unit actually works.
