How Long Does Freon Last?

Your AC unit keeps your home cool, but what keeps your AC cool? Freon.

What is Freon?

Freon is a product of DuPont, which is an aerosol propellant, used as a cooling agent for most air conditioning systems.

Other appliances and machines that provide air-cooling also make use of Freon, like refrigerators and the like. Once your cooling unit lacks coolant supply, it will blow out lukewarm air and defeat the purpose of your AC unit, so make sure to give it the right amount of Freon it needs.

Now, you are probably asking, “How long until I have to do this again?”

Never. Actually, Freon lasts forever. The only reason you would need more of it is because of a possible leak. Since the said refrigerant is circulated through copper refrigerated lines to keep your humble abode cool and keep the heat away, it stays inside the air conditioning unit, forever.

The substance passes through a closed and sealed area, which means that there is absolutely no way for it to get out of your AC unit.

Having a leak that wastes your Freon is very costly. Aside from regularly buying your air conditioning unit coolant, it burns a hole through your pocket with skyrocketing utility bills.


Your unit’s poor system performance will reflect on your bills. Since it cannot work optimally, it will use up more power to make it do so. This is dangerous, as it can damage your compressor—which is the heart of your AC unit. Once that happens, you are sure to shell out a large sum of money to get you through hot days.
