Where is the RV Air Conditioner?
Most RVs, travel trailers, and 5th-wheels come with an air conditioner pre-installed on the roof. It’s the big box looking thing normally located in the center.
If you have a large RV or 5th-wheel there can even be two or three AC units on the roof.
There are two main kinds of systems, ducted and non-ducted. Ducted is for larger trailers and RVs and non-ducted is normally found in small travel trailers, vans, and converted buses.
If you are looking to buy a new RV AC or upgrade the one you have it’s going to be important to know if it’s a 13,500 BTU or a 15,000 BTU unit.
Here are a few ways you can tell what kind of RV AC you have.
How Many BTUs Is My RV Air Conditioner?
A lot of RV AC units that come standard with an RV or travel trailer is 13,500 btu. Unfortunately, it can be hard to tell what the AC model is when you look at the air conditioner from the outside.
The easiest way is to check your spec sheet to see what model they installed from the factory.
Unit Model Number
If you don’t have the spec sheet or you want to be 100% certain you know the BTUs and model of your RVs AC unit you can remove the AC cover, also known as the shroud, and look for the model number somewhere on the unit.
Note there may be a few different model numbers on the unit since the various parts will sometimes also have serial numbers on them. It might take a little searching to find the AC unit’s actual model name and number.
Check Your RV’s Amperage
Another way to tell is by whether or not you have a 30 or a 50 amp RV. If you have a 30 amp trailer your RV AC is most likely a 13,500 BTU and if you have a 50 amp trailer with one RV air conditioning unit then it will probably be a 15,000 BTU.
Is It Ducted Or Non-Ducted?
The last way you can check is by whether or not your RV air conditioning system is ducted or non-ducted.
If it has ducts there will be circular vents spread out on the ceiling of your RV. A non-ducted RV AC only shoots air out of the main vent installed directly under the AC unit.
Non-ducted systems almost always use a 13,500 BTU RV AC or smaller. It’s a 50/50 on whether or not a ducted system will use the 13,500 or 15,000 BTU RV air conditioner. I have a ducted RV AC system in my travel trailer and the AC is only 13,500.
In the end, it depends mostly on what was ordered from the factory.
Most of the time a 13,500 btu RV AC unit will be installed unless a 15,000 was specifically asked for.
And as I said before the only for sure way to tell, unless you take the shroud off the AC on the roof and find the serial number, is to look at the spec sheet that came with the RV or travel trailer.
