The answer is: Never.
An caravan air con system that is running properly should not run out of refrigerant. Your AC system’s refrigerant doesn’t “use up” like gas in a car air con.
There is only one reason why your caravan AC may need more refrigerant. It has a refrigerant leaking problem.
In this article we will explain why healthy caravan ACs don’t use any refrigerant. We will also talk about the signs and how to deal with a refrigerant leak in your AC.
Why caravan air cons that are “healthy” should never run out refrigerant
Because refrigerant is contained in closed systems, caravan air conditioners don’t need to be added frequently. Refrigerant cannot escape from the system, in other words.
The refrigerant is contained in closed copper coils and runs in a huge loop through the caravan AC unit.
Caravan air conditioners can operate for their entire life span without the need to “recharge” with refrigerant.
It is possible for your AC to require more refrigerant. Let’s take a look at how and why your AC might need more refrigerant.
Refrigerant leakage: This is the only reason your refrigerant level would be low
The copper coils housing your refrigerant will wear down over time. Sometimes, tiny holes can form that allow the refrigerant to escape from the system.
You’ll eventually notice the signs that indicate a refrigerant leak. These include:
- Your caravan AC vents will warm up the air (except for cool nights).
- Frost or ice on refrigerant coils (this will be obvious at the evaporators coil).
- AC bills that are higher than normal
- Hearing or bubbling sounds near AC units

Is there a refrigerant problem? Here are some steps to take next
First, there are no DIY options for repairing a refrigerant leaking. The leak can only be repaired by an HVAC technician who is licensed to handle refrigerant. Why? Refrigerant is a toxic and flammable gas which can cause choking, headaches, and other health issues.
Beware! Scammers will try to “recharge” your system, but not actually repair the leak.
What does it do to you?
If the leak isn’t fixed, all your refrigerant will leak back. Refrigerant can be expensive. Freon, which is a common R-22 refrigerant, can cost anywhere from $75 to $175 per kilogram. A scammer tech will continue to take your money to recharge your system. It is the fast and expensive solution that only tech can provide.
