Different Types of RV Air Conditioners

RV air conditioners come in various types to suit different RV configurations and personal preferences. Understanding the different options available can help RV owners make informed decisions when choosing the right air conditioner for their vehicles.

Roof-Mounted RV Air Conditioner

The most common type of RV air conditioner is the roof-mounted unit. As the name suggests, this air conditioner is installed on the roof of the RV and provides cool air to the interior. It is designed to fit snugly on the roof and has a sleek profile to minimize wind resistance. Roof-mounted air conditioners are typically ducted systems, allowing the cool air to be distributed evenly throughout the RV.

Portable RV Air Conditioner

For those seeking flexibility and convenience, portable air conditioners are a popular choice. These units can be moved around and placed in specific areas of the RV, providing targeted cooling where it is needed most. Portable air conditioners are self-contained and do not require installation on the roof or any modifications to the RV. They generally come with exhaust hoses that need to be vented outside the RV to expel hot air.
