For most homeowners, Freon gas refrigerant is a word heard from time to time. Without refrigerants, air conditioning as we know it would not be possible.

These cooling agents circulate inside the air conditioner’s coils to cool and dehumidify the air in our homes.

Some people think their air conditioners work by pumping hot air out of their homes or offices, and pumping cool air in. That’s not quite right. The hot air is actually cycled back in as cold air. This circuit continues until the thermostat drops down to the target temperature.

If you’re like most people, you rely on your air conditioner in the summer to keep you cool and comfortable. Whether it’s in your car or home, many air conditioners use Freon as the refrigerant that cools the warm air.

What is Freon Gas?

The term or name Freon is commonly used to describe what is inside your home or vehicle’s air conditioner. The reason the Freon brand is so commonly used and referred to in today’s world is that the Freon brand was the first mainstream refrigerant that was used across the world.

The Freon refrigerant was invented all the way back in the 1930’s through a partnership with DuPont and General Motors. Together the companies synthesized the first CFC and HCFC refrigerants known as R-12 and R-22.

These new classes of refrigerants were trademarked by DuPont under the brand name Freon.

The moment these new refrigerants were invented they began to take off in popularity. That was because they checked all of the boxes of what the world was looking for in a refrigerant.

Uses of Freon

Freon is not only used in air conditioning systems, but it has also been used in various freezers. On top of those, there are a large number of commercial and industrial appliances that use Freon in both food transportation and cold storage warehouses.

How Freon works for cooling?

Freon undergoes an evaporation process again and again within most refrigerators in order to keep the temperature low. The same cycle is used for air conditioners. 

First, a compressor in your air conditioner compresses cold Freon gas. A small amount of oil is combined with the Freon gas to lubricate the compressor.

When this gas moves through the coils, it cools down to a liquid form. In this form, the cooled R-22 absorbs the heat from the outside air, then pushes the cold air out.

The result is low-pressure Freon gas. The cold gas is then channeled through another set of coils. This allows the gas to absorb heat and lower the air inside the room or building.

Your air conditioner filters the air in the room and cleans out dust, pollen, smoke and other kinds of dirt

Air conditioners often take excess water from the air to use it to cool down the system, and pump it outside through a hose. In this way, they dehumidify the air inside.

Alternatives To Freon

As manufacturers phase out R-22 refrigerants, newer environmentally-friendly alternatives are being developed, like R-410A. 

R-420A is recognized by the Environmental Protection Agency to be ozone-friendly, so many newer AC models are being designed to use this refrigerant. Luckily, this benefits the environment as well as your budget.

Freon at Home

Although air conditioner manufacturers are required to phase out R-22 systems, the use of R-22 refrigerant is still allowed in systems manufactured prior to 2010. 

With the phase out, it may get more expensive to use Freon, which will encourage homeowners to replace older AC models with more ozone-friendly products.

Not only will that decrease your repair costs, it should also provide more efficient cooling and heating. That will definitely save you money on your utility bills.

Although you won’t be required to stop using R-22, the long phase out period is designed to provide plenty of time for you to make the switch as the items in your home get older. 

If you do own an item that uses R-22, make sure it has regular preventive maintenance to minimize the impact on the environment until you are ready to replace it.
