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.

How much does an empty 25 lb Freon tank weigh?
An empty 25 lb Freon tank typically weighs around 16-18 lbs.
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 can I check the freon levels in my AC unit?
To check the freon levels in your AC unit, you will need to hire a professional HVAC technician. They have the tools and expertise to safely and accurately measure the freon levels in your system. It is not recommended for untrained individuals to attempt to check or adjust freon levels themselves.
How can I check the freon levels in my home AC system?
To check the freon levels in your home AC system, you will need to hire a professional HVAC technician. They have the tools and expertise to safely and accurately measure the freon levels in your system. It is important to have the freon levels checked regularly to ensure your AC system is running efficiently and effectively.
How do you test for Freon poisoning?
Freon poisoning symptoms include dizziness, headache, nausea, and difficulty breathing. To test for Freon poisoning, a healthcare provider may perform a physical exam, review symptoms, and may conduct blood tests to measure Freon levels in the blood. Treatment usually involves removing the person from the source of exposure and providing supportive care.
