The choice of an RV air conditioner can be overwhelming. There is an endless list of options and plenty of compatibility concerns.

Most people talk about an RV air conditioner's size in terms of its BTU rating, which is essentially a measure of power. The higher the BTU rating, the greater its cooling capacity.

Several factors, such as the size of the RV, insulation properties, and number of rooms, must be considered when choosing the correct size (AKA BTU rating) for your RV.

We recommend sticking with the manufacturer's suggestion, which you can get by calling the manufacturer directly with your vehicle identification number (VIN).

Here's a general size chart to estimate the BTU requirement for your RV:

Keep in mind that this is just an estimate, and you should consult the manufacturer's suggestion for a more accurate size.

A 13,500 BTU RV air conditioner will require at least 3,500 starting watts, and a 15,000 BTU RV air conditioner will need upwards of 4,000 starting watts.
