RV air conditioners are essential for keeping the interior of recreational vehicles cool and comfortable during hot summer days. However, many RV owners are curious about the power consumption of their air conditioning units. In this article, we will explore how many watts an RV AC typically uses and discuss factors that can affect its energy consumption.

Understanding RV AC Power Consumption

The power consumption of an RV air conditioner is typically measured in watts. The exact wattage can vary depending on several factors, including the size and efficiency of the AC unit, the ambient temperature, and the insulation of the RV.

On average, a rooftop RV air conditioner can consume anywhere between 1,200 to 1,800 watts of power when running. This power requirement is for the cooling mode, and it may increase slightly when the AC unit is also operating in dehumidification mode. It’s important to note that these values are approximate and can vary between different models and brands.

Factors Affecting RV AC Power Consumption

1. Size and Efficiency: Larger RV air conditioners with higher cooling capacities tend to consume more power. Additionally, newer models with higher energy efficiency ratings (EER) can provide the same cooling effect while using fewer watts compared to older models.

2. Ambient Temperature: The outside temperature can impact the power consumption of an RV AC. In hotter climates, the AC unit may need to work harder to maintain the desired indoor temperature, resulting in increased power usage.

3. Insulation: The insulation of the RV plays a crucial role in minimizing heat transfer between the interior and exterior. Well-insulated RVs require less power to cool down, as the cool air is retained more effectively.

4. Thermostat Settings: Lowering the thermostat temperature will increase the workload on the AC unit, leading to higher power consumption. Setting the thermostat at a moderate temperature can help optimize energy usage.

5. Usage Patterns: The frequency and duration of AC usage also impact overall power consumption. RV owners who frequently use their air conditioners for extended periods will consume more power compared to those who use it sparingly.


The power consumption of an RV air conditioner can vary depending on factors such as the size and efficiency of the unit, ambient temperature, insulation, thermostat settings, and usage patterns. On average, an RV AC can consume between 1,200 to 1,800 watts when running. It’s important for RV owners to consider these factors and optimize their energy usage to ensure a comfortable and efficient cooling experience while minimizing power consumption.
