Frequently Asked Questions (FAQ)

Which RV air conditioner is best?

Go with an RV air conditioner that is user-friendly and efficient. This means that you must consider your regular camping style and the space you will place your product. You should always research both indoor and outdoor air conditioners to determine which one is made for your needs and lifestyle.

What is the highest BTU RV air conditioner?

The highest BTU RV air conditioners are units that reach the highest levels of cooling power. This means the highest BTU air conditioners have between 12,000 and 18,000 BTU’s. This is out of all units available because the BTU levels are usually listed as R-6000, R-8000, R-12000, etc.

If you are looking for an air conditioner that will cool your entire motorhome, this is the right category for you. Since these are few and far between, we recommend going a size lower to make sure you have enough BTU power for your needs. Some RV air conditioner manufacturers have even started combining two smaller units into one to reach even higher levels.

What size RV AC do I need?

The first step to getting an air conditioner installed is to find out the size of your RV. In almost every case, you will require a window unit. The reason for this is because you need to take the width, height, and depth of your RV into account.

Before you buy a portable AC unit, you will first need to calculate the size of your RV. Once you know your sizes, you will be able to match the appropriate portable unit.

There are uniquely sized air conditioners for RVs, however you can also place a standard-sized window unit inside of your RV. Yes, this means that even if your RV is bigger than the AC unit you plan to buy, you can still make it work.

Most often, it’s easier to go with a normal-sized window unit because RV air conditioners are generally too bulky and heavy for regular use.

What is the smallest RV air conditioner?

Before your decide which you want, it is important that you know the physical measurements of the air conditioners. When you are looking at them, you are looking at the size of the unit, not the size of the tube.

When figuring out how much space you have for the unit, you want to make sure that there is enough room for it to fit comfortably and that the air conditioner does not touch any surfaces or walls.

The smallest air conditioner that you can get is the Coleman Mini. It is a 9,000 BTU portable air conditioner, and the dimensions of the unit are 8.5 x 16 x 16.5 inches. The reason that it is the smallest is because the dimensions give you the length, width, and height.

Conclusion

Air conditioners are must-have items to RV owners. Being able to stay cool in summer without using the regular RV water heater is a plus for energy efficiency as well as staying comfortable. But you need an RV air conditioner that meets your needs and has good reviews and value soon to select the best RV air conditioner.
