"My refrigerator is not cooling, it needs a shot of freon."
If you're ready to get a better understanding why you likely don't need freon and the above statement is a myth, buckle up.
Freon is a brand name of refrigerant.
R-134a (AKA refrigerant #134a) is the chemical home appliance manufacturers have used for the last 20-30 years in home refrigerators.
A small refrigerant leak in a home refrigerator can be critical to it's proper function
Every bit of refrigerant is important to a household refrigerator
(Sub-Zero Refrigerator Leaking Refrigerant)
Improper checking of "freon levels" can be enough to cause temperature problems
The Sub-Zero seen in this photo needed refrigerant but also needed an evaporator
Without replacing the evaporator (component that was actually leaking) this unit would likely only work for a short while before re-experiencing temperature problems
Large roof top Air Conditioning / refrigeration systems wont miss a few ounces of refrigerant
Home appliances however like this Sub-Zero refrigerator only holds 4.5OZ total. Losing 3.0 Ounces will mean no cooling shortly after
90% of refrigerator repairs are electrical and not refrigerant (Freon) related.
That means chances are high you don't need a shot of freon but rather something electrical and more cost effective
