7 Hacks to Stay Cool Without A/C

Let’s face it - summer RVing is amazing, but when your air conditioner can’t keep up (or worse, breaks down), things get sweaty fast. Whether you’re boondocking, dry camping, or just trying to conserve energy, learning to keep your rig cool without A/C is a must-have skill for every RVer.

Here are 7 tried-and-true hacks we swear by to beat the heat and stay comfortable on the road.

1. Park Smart: Shade Is Everything

Where you park makes a huge difference in your RV’s temperature. Always aim to:

Park with your largest windows facing away from the sun
Use trees, buildings, or even tall shrubs for natural shade
Consider east-facing sites if you’re staying multiple days—morning sun is cooler than late afternoon sun

Pro Tip: Don’t just look for shade overhead—ground heat reflects up, so shade all around helps.

2. Reflective Window Covers Are a Game Changer

The difference after adding reflective window covers is instantly noticeable. These block sunlight and help insulate your windows.

Recommended: Reflectix Insulation Roll – Cut to fit and tuck in for a custom solution
For doors and windshields: Camco Sunshield Reflective Window Cover

Pro Tip: Add blackout curtains or thermal curtains for an extra layer of heat protection.

3. Maximize Ventilation

Use your roof vents and windows strategically. Create cross-ventilation by opening a window on one side and a roof vent or window on the opposite side. This encourages airflow through your rig.

Don’t forget to:

Crack roof vents slightly even when closed up during the day
Open everything up at night to let cooler air in

4. Invest in Battery-Operated or USB Fans

Fans don’t cool the air, but they help you cool off by increasing airflow and evaporation.

Recommended:

Clip-On Rechargeable Fan – Clip it to your bed or counter
10-Inch Portable Fan – Great for boondocking

Place fans near windows or vents to circulate fresh air through the RV.

5. Switch Up Your Cooking Strategy

Oven and stovetop cooking heat up your rig fast. Try:

Cooking outdoors with a portable grill
Using an Instant Pot or air fryer
Prepping cold meals (think pasta salad, sandwiches, or wraps)

Stay cool and keep your energy use down by meal prepping in the morning.

6. Chill Your Bedding

A hot bed is a recipe for restless sleep. Try this:

Store sheets or a gel cooling pillow in your fridge or freezer before bed
Use lightweight, breathable bedding like bamboo or cotton
Try moisture-wicking sheets designed for hot sleepers

Recommended: Cooling Gel Memory Foam Pillow

Bonus: Mist your sheets with water and run a fan nearby for evaporative cooling.

7. Stay Hydrated and Use Cold Compresses

When all else fails, cooling your body helps more than cooling the air:

Drink cold water frequently
Wet a washcloth and place it on your neck or wrists
Freeze water bottles to use as makeshift ice packs

A quick rinse with cold water (even if just your feet) goes a long way in lowering your body temp.

Sure, A/C is great—but it’s not the only way to survive the summer heat. With these simple hacks, a little planning, and the right gear, you can stay cool and comfortable wherever the road takes you. If you’re planning a trip, make sure your rig is stocked with Essential RV Tools Every RVer Should Keep On Hand—because a well-prepared RV is a cool RV. 😎

See you on the road!
