On smaller residential air conditioners the manufacturer publishes a charging chart that has the outside air temperature and the corresponding suction and liquid pressure measured by a refrigeration manifold set, gauges.
If the chart is not available, you can estimate by measuring the suction pressure and then using a pressure temperature chart for your refrigerant and trying to maintain a 35 degree to 40 degree temperature at the condensing unit or compressor.
The other measurement on larger units is the subcooling measurement, measure the actual liquid line temperature and compare the liquid pressure using a pressure temperature chart and also checking for bubbles in the liquid line sight glass.
On larger systems after the subcooling has been checked then the superheat has to be checked and the thermostatic expansion valve adjusted if necessary. To check the superheat, measure the suction pressure, convert to a temperature and then measure the actual suction line temperature. The difference is the superheat, should be 6 to 20 degrees depending on the system.

What is the density of Freon?
The density of Freon is 1.494 grams per cubic centimeter.
Why does low freon cause ice formation on a dehumidifier?
There is ice on the dehumidifier coil because it is low on freon. When there is not enough freon in a refrigeration system the inlet pressure to the compressor is lower than design due to lack of gas. Because it is at a low pressure the freon is very cold. This causes freeze-up. If You were to add freon to the running dehumidifier you would see the cold coil thaw, first at the end closest to the compressor suction and then work toward the other end of the coil. When the thaw reaches the other end of the cold coil it has enough freon and no more need be added. Tim Koller

How much freon does a refrigerator have?
i has a hundre pices to set up
How do you measure freon weight in HVAC?
not dure if this will help but when i charge a unit either low or complete charge,the jug is weighed before the charge and after to see the weight of freon
How much freon R-22 to be charge in a freezer or meat room?
About twenty pounds of pork, and maybe some garlic for good measure.
Is r22 freon compatible with r 134a freon?
Is r-22 Freon compatible with r-134a freon?
Where do you add freon on a 1997 mountaineer?
Contains no Freon. Freon was banned beginning in 1996.
What is the symbol for freon?
Freon is DuPont's trade name. There are 2 types of Freon, Freon-11 is trichlorofluoromethane, while Freon-12 is dichlorodifluoromethane. All types of Freon have been banned from production since 1996. Refrigerants are manmade compounds not Elements
Can r404-a freon be substitted for r22 freon?
NO
When should refrigerator freon be checked?
When the fridge is not cooling due to freon leak or freon restriction.
Does one need a license to handle freon in Arizona?
Home freon and R-12 freon for vehicles (yes) but not R134a freon which you can get at any autozone..................
Can we use freon ourselves?
There is many different types of Freon. If the freon that you are trying to use is R-22 then you have to have a EPA certification to handle that freon. This freon is considered ozone depleteing. Now there is freon out there that is not ozone depleting like the freon in cars made after 1993. That is called R-134a which is sold everywhere even in Wal-Mart.
Where is the intake valve for Freon on 03' Ford Expedition?
Contains no (R12) Freon. Freon was banned in 1996.
Does r134a freon have a smell?
R134a Freon is an oxymoron, Freon is R12 but the answer is yes, a subtle 'sweetish' odor
Can freon 12 be used in place of freon 22?
No
