There is a LOT of false advice going around about recharging your RV air conditioner. When I typed the search phrase “Can I recharge my RV air conditioner?” into Google, 8 of the first 10 results told me that yes, I could recharge my RV rooftop air conditioner, and it was easy to do! 

I suspect most of this content is brainlessly concocted by AI. Here’s my “favorite” tidbit of advice: (Don’t follow it!).

“If your RV’s air conditioner needs recharging you’ll need to determine the type of refrigerant it needs first,” says the article. “Before you start working remember to turn off the power, then open up the unit and pour in the refrigerant.” My friends, if you can “pour” refrigerant into the system, you must be in Antarctica, because this stuff boils at -55 degrees Fahrenheit!
