2. **Understand Their Properties**: Freons are characterized as colorless, odorless, non-flammable gases that have low toxicity. These properties make them suitable for various applications.

3. **Recognize Their Uses**: The primary commercial use of Freons is as refrigerants. They are commonly used in refrigeration and air conditioning systems due to their ability to absorb heat.

4. **Mention Specific Examples**: Some common examples of Freons include chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). These compounds have been widely used in the past for refrigeration.

5. **Conclude with Their Importance**: Despite their effectiveness as refrigerants, it is important to note that some Freons, particularly CFCs, have been phased out due to their harmful effects on the ozone layer.

**Final Answer**: Freons are used as refrigerants.
