Sleezstack is correct. r134a is the new refridgerant.
The word Freon© is a Dupont Corporation registered trade name that has long been the generic term for refrigerants. These refrigerants are derivatives of hydrocarbons (compounds of hydrogen and carbon), but also contain elements called halogens (such as chlorine and fluorine). The new name on the block is "Suva©," a high pressure chlorine free hydrofluorocarbon refrigerant, and also a registered trademark of the Dupont Corporation. Freon is the dinosaur that is soon to be a fossil and Suva is the new breed. The big issue today in using Freon and other refrigerants is the elimination of CFC's which are chlorofluorocarbon refrigerants. These new refrigerants are required to have low ozone depletion potential and low global warming potential, as well as keeping energy efficiency in perspective.
R-12 (dicholordifluoromethane) is the refrigerant used in virtually every residential refrigerator, every auto air conditioner, and in most commercial coolers. The replacement of Refrigerant 12 will directly affect consumers the most. The first location will be in the automotive air conditioner. The new replacement for R-12 is R-134a which is not a Freon, but a Suva. R-134a is less efficient than R-12 and operates at a higher pressure. The net results of these two factors will be more horse power from the car's engine to yield the same cooling. More horsepower means lower fuel economy and poorer engine performance.
"Methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things the of the faith derive from the same God. The humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God in spite of himself, for it is God, the conserver of all things, who made them what they are" (CCC 159).
Real Christianity has no fear of science or scientific discovery.

Fridge = Fred Phelps
Gas = Bigotrous Nonsense
To answer your question: Too much. Someone should open the fridge and let some of the gas out and some light in. However, the gas may harm the ozone layer.

Freon;
Refrigerators from the late 1800s until 1929 used the toxic gases, ammonia (NH3), methyl chloride (CH3Cl), and sulfur dioxide (SO2), as refrigerants. Several fatal accidents occurred in the 1920s because of methyl chloride leakage from refrigerators. People started leaving their refrigerators in their backyards. A collaborative effort began between three American corporations, Frigidaire, General Motors and DuPont to search for a less dangerous method of refrigeration.
In 1928, Thomas Midgley, Jr. aided by Charles Franklin Kettering invented a "miracle compound" called Freon. Freon represents several different chlorofluorocarbons, or CFCs, which are used in commerce and industry. The CFCs are a group of aliphatic organic compounds containing the elements carbon and fluorine, and, in many cases, other halogens (especially chlorine) and hydrogen. Freons are colorless, odorless, nonflammable, noncorrosive gases or liquids.
Side Note: Charles Franklin Kettering invented the first electric automobile ignition system. He was also the vice-president of the General Motors Research Corporation from 1920 to 1948. General Motors' scientist, Thomas Midgley invented leaded (ethyl) gasoline.
Thomas Midgley was chosen by Charles Franklin Kettering to head the research into the new refrigerants. Frigidaire was issued the first patent, US#1,886,339, for the formula for CFCs on December 31, 1928.
In 1930, General Motors and DuPont formed the Kinetic Chemical Company to produce Freon. By 1935, Frigidaire and its competitors had sold 8 million new refrigerators in the United States using Freon made by the Kinetic Chemical Company. In 1932, the Carrier Engineering Corporation used Freon in the world's first self-contained home air conditioning unit, called an "Atmospheric Cabinet".
Because Freon is non-toxic, it eliminated the danger posed by refrigerator leaks. In just a few years, compressor refrigerators using Freon would become the standard for almost all home kitchens. In 1930, Thomas Midgley held a demonstration of the physical properties of Freon for the American Chemical Society by inhaling a lung-full of the new wonder gas and breathing it out onto a candle flame, which was extinguished, thus showing the gas's non-toxicity and non-flammable properties. Only decades later did people realize that such chlorofluorocarbons endangered the ozone layer of the entire planet.
Side Note: CFCs, or Freon, are now infamous for greatly adding to the depletion of the earth's ozone shield. Leaded gasoline is also a major pollutant, and Thomas Midgley secretly suffered from lead poisoning because of his invention, a fact he kept hidden from the public.
Thomas Midgley discoveries ranged from a way of getting salt into popcorn before it was popped, to a method for treating the contents of a swimming pool so that people could swim farther underwater.

That question belongs in Home Maintenance and Repairs.
But R-134 IS a form of Freon, which is the answer to your question. But as you should evac the system before you refill it, you're better off having it done professionally.
