Freon is the name given to a particular type of refrigerant that was used prior to this year. If you have a system that still uses Freon, then it’s time to start considering a replacement. First off, this means that your air conditioner is on the older side, and well cared for cooling systems are designed to last about 10-15 years. Secondly, Freon is bad for the environment.
The type of refrigerant used in AC systems today is more environmentally friendly, and absolutely necessary for the functionality of your cooling system. It’s the component that actually allows the cooling system to cool. But, you could have a refrigerant leak, and when your air conditioner is low on refrigerant, it can experience a number of problems.
