Air conditioners that were once a luxury have now become a necessity in many households and offices. Therefore there has been a considerable rise in the use of air conditioners in recent years. These machines save you from the rising temperatures and keep you cool.

Air conditioners work in a very efficient way that is; they pull in the hot air in the room and transfer it outdoors. Besides this, they also purify the air at home, getting rid of dust particles and pollen that can cause allergies. Air conditioners are such a blessing to us with so many advantages, but are they good for our environment?

Air conditioners have a long history, with many changes due to development of technology. In the beginning, these machines were quite dangerous to humans because of the chemicals they used. Gradually, to improve the efficiency of these cooler machines, Freon was used as a refrigerant in air conditioners as they did not cause any harm to people. Freon emits chlorofluorocarbons, which are harmful to the environment.

These CFCs are major culprits in depleting the ozone layer which increases the danger to our environment.

In recent years though, scientists have managed to discover substitutes to CFCs. Keeping the environment in mind, air conditioners are made and installed in ways that are safe to both the environment as well as humans. Servicing and maintaining air conditioners also helps protect our environment which is the responsibility of each one of us.
