How often does Freon need to be replaced in a car?

I just bought a car and I want to make sure I take really good care of it. I know about oil changes and filters, but what about the AC system? How often does Freon need to be replaced in a car?

You’re a very thorough car owner—we love to see it! Most AC systems can last around five years without a Freon top-up, unless you live in a very hot climate.
Freon is a kind of refrigerant that is recirculated in your vehicle in a closed system to cool down the interior. So, your car won’t really run out of Freon since it is reused inside the sealed system. Some loss of refrigerant is normal over time, even without a leak, but it shouldn’t affect the functioning of your AC system.
Do you live in a very hot climate? If so, you may use your air conditioning more frequently than someone who lives in a cold climate. More use means that you may need a Freon recharge sooner.
Freon replacement is not typically listed on a regular
service maintenance schedule
for most vehicles, since it’s rare that it needs to be replaced. You’re safe to drive without checking the Freon for at least five years—or until you notice a problem (like no cool air).
If you need Freon more frequently— like if you’re not able to cool down your vehicle even if the refrigerant was recently topped up—then you may have a leak.
It sounds like you’re doing all the right things to ensure a long, happy life for your vehicle. Regular maintenance goes a long way toward keeping the cost of car ownership low.
