When you buy a new house AC unit (Carrier, Trane, etc) does the unit come
with the Freon already pressurized in the unit...or does the installer add
the Freon after everything is set.
Also...in an older unit...can you rent a recovery tank and valve setup to
save the old Freon that's in the unit...or again..does an ac installer guy
have to do this ?
thanks, Tim R
Condensor comes precharged with refrigerant. The only losses are what
escapes when the refrigerant lines are reconnected. This loss must be
Refrigerant recovery, I think requires a license in each state. That
is, you have to take a course and pass to get a certificate that makes
you a licensed refrigerant recovery person. So no, IMO, you cannot rent
a refrigerant recovery cart without a license to operate it.
There is no loss when the lines are made up.....jesus
Yes, they come precharged...precharged for that particular
condenser...a matching evaporator and a manufacturer specified amount
of tubing between the two units. Some manufactures add enough for 15
foot of tubing some for 25....this charge still may need to be added to
because of increased tubing length etc.... and it still must be checked
and adjusted by a competant person because the factory charge may not
be correct..especially if charged at the factory by a fat lazy american
with no work ethic.... also checking the charge will also show any
problems with the system itself....too little airflow, kinked
You need a professional to check out the equipment...too much or too
little gas both can result in increased compressor wear.
refrigerant recovery..... look for the access ports on the outside
unit...take a valve core remover...like you would use for a car or
bicycle valve stem and loosen the core to where you hear a steady
hissing......come back the next morning and push in on the stem....if
it hisses just a little bit just remove the corer completely..do this
on the big line to minimize the release of tell tale liquid
If you are going to attempt this yourself...good luck...you have not
mentioned proper brazing techniques, leak testing...evacuation.....
and they call me corny................ ~:>
The new unit comes with enough freon for up to 15 foot line set, or
maybe 25 feet.
You need a license from the Federal government to add or remove freon
from any appliance or device.
For whatever reason, some auto parts stores sell R-134a, which must
not be considered a controlled refrigerant, then?
