What does Freon do in an air conditioner?

Freon is a non-combustible gas that is used as a refrigerant in air conditioning applications. This freon undergoes an evaporation process over and over again to help produce cool air that can be circulated throughout your AC system.

Is Freon used in air conditioners?

For decades, Freon, also known as R-22 and HCFC-22, was the main refrigerant used in residential AC units. However, new AC systems made since 2010 no longer rely on Freon, instead using a refrigerant called R410A, or Puron, that has been shown not to harm the ozone.

How long does Freon last in AC?

An air conditioner’s refrigerant’s system is a closed (or sealed) system, meaning there is no way for the Freon to escape; since Freon does not get used up, as long as there are no leaks, your AC’s Freon will keep doing it’s thing indefinitely.

What does it mean when your air conditioner is low on refrigerant?

Well, something similar to that happens in your air conditioner is low on refrigerant. Low refrigerant means low pressure and low pressure means low temperatures that will eventually freeze something called an evaporator coil.

How can you tell if your central air needs Freon?

If air flow seems fine, but the air coming up isn’t cool, then you likely have a refrigerant problem. This happens because the evaporator coil cools down too much, causing cold refrigerant to flow back into the system. This creates low surface temperatures which causes condensed water vapor in the air to freeze.

What happens when the Freon level in your car is too low?

The AC clutch will fail to engage since the level of Freon is too low for the compressor to pressurize. But that is a sign that might not be so obvious. The good news is that your car will exhibit other low refrigerant symptoms. Here are some of them.
