What Is An RV AC?

In essence, an RV AC is an air conditioner that is designed for an RV. Since an RV AC is designed for an RV, rather than a traditional home, it looks a little different from a traditional AC and it functions a little bit differently, as well.

Why Is An RV AC Useful?

Having an RV AC is exceptionally useful, because it allows you to bring cool air into the interior of your RV.

If you are driving through a hot and humid location, or are staying somewhere that’s very warm, then having an RV AC ensures that you won’t be uncomfortable during that experience.

Many RV ACs offer more than just air conditioning functionality, though; they also offer heating functionality. By making use of this heating functionality, you are able to cool the interior of your RV, and to heat it up, as well.

How Easy/Hard Is It To Install An RV AC?

The answer to this question definitely depends on both the RV AC, and the RV that it’s being installed into.

Do I Need Two Air Conditioners

If the RV AC is extremely heavy, and no one is helping you bring it to the top of your RV, then that will make the installation process very difficult. If the manual is difficult-to-understand, and you are unsure as to what you need to do to install the RV AC, then that, too, will make the installation process very difficult. If the design of the RV AC is convoluted and confusing, then that will also make the installation process quite difficult.

If, to name some alternatives, the RV AC is relatively lightweight and designed in a clear and concise manner, then it will be significantly easier to install. If the manual that the RV AC comes with is easy-to-read and understandable, then the RV AC will be especially easy to install.

For the easiest installation process, find an RV AC that is lightweight and well-designed while also coming with a good manual.

What Size RV AC Do You Need?

To install your new RV AC, you will have to do so by going onto the ceiling of your RV and placing it through the duct hole that is on your RV. To find the right size for your new RV AC, you must measure that duct hole.

How to Select the Best Portable RV Air Conditioner

Without measuring the duct hole, you may end up purchasing an RV AC that is too big – or small – for the RV. But, when you know the size of the duct hole, you can purchase an RV AC that is just right for the specifications of your RV.

Conclusion

In the end, every RV is a little bit different when it comes to the RV AC that they need. To find the right RV AC, measure the duct hole in your RV’s roof and use those measurements.
