No, an RV (Recreational Vehicle) air conditioner does not run on propane. RV air conditioners operate using electricity as their power source, similar to the air conditioner units found in homes and buildings.
Most RVs are equipped with rooftop air conditioners, which are designed to be powered by the RV's electrical system when connected to a shore power hookup at a campground or an external power source. These air conditioners typically run on 120-volt AC power.
When the RV is not connected to a shore power hookup or a generator, the air conditioner cannot operate unless the RV has an auxiliary power source, such as solar panels or an inverter system, which can provide the required electricity.
Propane is commonly used in RVs for powering appliances like stoves, ovens, water heaters, and refrigerators, but it is not used to operate air conditioners.
