Types of RV Air Conditioners

Usually, there are two types of RV air conditioners: ducted units and non-ducted units. The latter ones are the most common yet simplest type of air conditioners for RV. These travel trailer air conditioners adjust into a hole cut in the vehicle’s roof. However, most non-ducted ACs can fit into your RV roof vents. These models consist of the blower, condenser, and compressor inside the aerodynamic yet sturdy body. If you have a small RV that does not need to distribute air across larger spaces, then non-ducted units are the perfect option for you.

Roof air conditioner

However, ducted AC does not have a control unit inside the RV. Rather, these models control the vehicle’s temperature by passing the air through a duct system connected through walls, floors, or roof of the RV. This type of RV air conditioner is best for larger vehicles.
