If you own an RV, you already know how important it is to protect every part of it—especially your air conditioner. Your RV AC unit is exposed to the elements year-round, which makes it vulnerable to dirt, rain, UV rays, snow, and even curious critters. That’s where an RV AC cover comes in.
This simple but effective accessory helps protect one of the most valuable systems in your RV from weather damage and premature wear. Whether you’re storing your RV for the winter or parked at a campsite, an RV AC cover is a must-have item for every responsible RV owner.
What Is an RV AC Cover?
An RV AC cover is a specially designed protective covering that fits over the exterior portion of your RV’s rooftop air conditioner. It’s usually made from durable materials such as:
- Heavy-duty vinyl
- Polyester oxford fabric
- Waterproof PVC
- UV-resistant plastic
Some AC covers are designed for storage use only, while others can stay on while you’re traveling, depending on their design and purpose.
Why You Need an RV AC Cover
Here’s why investing in an RV AC cover is a smart move:
1. Weather Protection
Rain, snow, sun, and ice can wear down your AC unit’s housing and internal components over time. A cover helps shield it from the harshest conditions.
2. UV Damage Prevention
Prolonged sun exposure can cause plastic components to crack, fade, or become brittle. UV-resistant covers block harmful rays and extend the life of your unit.
3. Pest Deterrent
Wasps, birds, and rodents sometimes crawl into uncovered units to nest. A snug-fitting RV AC cover prevents these unwanted guests from getting in.
4. Keeps Debris Out
Leaves, twigs, dust, and pollen can clog your AC unit’s vents and reduce efficiency. Covers help keep your unit clean and maintenance-free.
5. Energy Efficiency
Keeping your unit in good condition means it runs more efficiently, saving you energy and extending the system’s lifespan.
Types of RV AC Covers
There are two main types of RV AC covers:
Storage Covers
Used when your RV is not in use, especially during off-seasons like fall or winter. These are not meant to be used while driving or when the AC is running.
Shroud Replacements
These are permanent plastic covers (also called shrouds) that replace a damaged outer shell of your AC unit. Unlike storage covers, they are designed to stay on full-time.
When shopping, make sure the cover is compatible with your AC model—brands like Dometic, Coleman, and Advent have differently sized housings.
How to Choose the Right RV AC Cover
Here are some key factors to consider when choosing your cover:
- Fit & Compatibility: Measure your AC unit or find a model-specific cover for a snug fit.
- Material Quality: Look for waterproof, UV-resistant, and tear-resistant materials.
- Ease of Installation: Velcro straps, zippers, or drawcords make removal and setup easy.
- Breathability: Some covers offer mesh vents to prevent moisture buildup and condensation.
- Wind Resistance: If you’re storing your RV in a windy location, choose a cover with extra securing features.
Installation Tips
Installing an RV AC cover is simple:
- Turn off the AC and allow it to cool.
- Clean the surface of the unit to remove dirt or debris.
- Position the cover over the unit and secure it using straps or fasteners.
- Double-check the fit—make sure no part is left exposed.
- Remove the cover before operating your air conditioner.

Final Thoughts
An RV AC cover may seem like a small investment, but the protection it provides is invaluable. From weatherproofing and UV defense to pest control and efficiency preservation, a good cover saves you money and hassle in the long run.
So, before you tuck your RV away for the season—or even just a few weeks—make sure your rooftop air conditioner is protected. Your future self (and your wallet) will thank you.
