Refrigerant: The Cool in Your Cooling System

Refrigerant and Your AC

Your AC is built all-around with a certain chemical: refrigerant (or coolant). This chemical substance in its various forms works to transform warm air into cool air, thus allowing the fan on your AC to circulate that cool air throughout your home.

Here’s what you need to know about how refrigerant works in your AC.

Types of Refrigerant

The two modern types of refrigerants are R-22 and R-410A. R-22 contains chlorine, which is harmful to the environment and is actually being phased out (more on that later).

The Environmental Protection Agency recommends R-410A as the modern replacement for R-22, as it is not harmful to the environment. This is now the standard type of refrigerant used in new AC units.

The R22 Ban

The United States issued a ban on R-22 refrigerant due to its environmental impact and harmful effects on the ozone layer. R-22, along with R-142b, both ceased production and import on January 1, 2020. You can no longer buy new versions of these products. Though it is important to note that R-22 is not forbidden to use, so you don’t need to rush right now to replace your system if it uses this refrigerant.

Since R-22 is no longer in production, its supply is limited, growing more scarce, and rising in price. If your AC is older in age and uses R-22 refrigerant, you may want to consider upgrading to a newer unit to avoid any supply issues or having to pay extra money to get the right chemical.

Refrigerant Leaks

A significant problem that can happen to your AC is a leak in the refrigerant line. Refrigerant is placed in a closed system, which means you don’t need to refill it in order for it to work. Therefore, if your system’s coolant is depleted, there is likely a leak.

If your AC is blowing warm air, it is likely due to a refrigerant leak. Leaks should be fixed as soon as possible to keep your home comfortable and to avoid further damage.
