Summary
Some argue that air conditioning is one of our greatest inventions. Stuffy, hot, and humid rooms that were once unbearable are now places that are pleasant to work in. There’s no question that air conditioning in RVs is a valuable resource; those metal boxes can heat up quickly in the sun. When you also consider that desert areas are some of your favorite places to take your RV, air conditioning is essential in those climates.
Like anything else you rely on in life, air conditioners break down or you may not even own one on your ride. What can you do to keep cool? Here’s how to keep an RV cool without air conditioning.
3 Things to Do to Keep It Cool When RVing Without Air Conditioning
Keep the Air Flowing
You’ve probably thought about opening windows; however, randomly opening them can only do so much. The goal is to create a direct flow of air through the RV. Try to determine which way the wind blows and open the corresponding windows to form a continuous stream of air. It’s even more effective if the windows are on opposite sides—especially when one is higher and the other lower—as this will create suction and improve airflow.
Pro Tip: Use fans, if possible, to force air out of your RV to help keep it cool when windows are open. Remember, all a fan does is circulate air, it doesn’t make you cooler, so use those fans to expel warm air and enhance your comfort.
Keep the Heat Off
Avoid any activities inside the RV that can generate extra heat. Try not to cook, and also refrain from using appliances like dishwashers or clothes dryers. That load of laundry can wait for the cooler evening or morning hours. If staying at an RV park or campground like KOAs, utilize the facilities that often offer appliances, keeping your RV cooler in the process.
Pro Tip: Grill meals outside to prevent heat from being trapped inside your RV or trailer. Not only does grilling enhance the flavor of your food, but it also keeps your RV cooler than cooking indoors.
Keep the Sun Out
You can proactively manage heat by employing strategies that reduce sun exposure on your RV. Consider installing solar shields for your windows and windshield, which you can typically find at any RV supply store or many auto parts retailers. These shields reflect solar heat, preventing your RV from absorbing and storing it.
Awnings also serve as an excellent barrier against sunlight. Not only do they expand your patio area around the RV, but they also shield a significant portion of your RV from harsh sun. Awnings are a beneficial investment for any RV owner.
Pro Tip: If your RV lacks awnings, consider investing in a canopy, provided you have the storage space for it. A small canopy or a makeshift one using a tarp and poles can help keep you cool on sweltering summer days.
Make Your Air Conditioning with an RV Swamp Cooler
You can construct a DIY AC unit, often referred to as a swamp cooler, to keep your RV cool. Not only is this method easy, but you likely have most of the materials already on hand.
Here’s what you need to create an RV swamp cooler:
- Large Styrofoam cooler
- Plastic cups
- A knife
- Ice bucket and ice
- Standard fan
To make a basic RV swamp cooler, follow these instructions:
- Cut a large circular hole on the cooler’s lid for the fan. The fan should rest securely so that it doesn’t topple the cooler. If your cooler is large enough, you could also make the hole in the side.
- Punch three to four holes in the side of the cooler that match the size of your plastic cups. Cut the bottom out of your plastic cups and insert them into the holes to serve as vents.
- Fill the cooler with the coldest ice available (dry ice is ideal if accessible). You can place the ice in an ice bucket inside the cooler if preferred.
- Ensure all fittings are tight and sealed correctly.
- Turn on the fan and direct the cup vents in your desired direction.
No one enjoys feeling hot and sticky, especially when inside an RV without air conditioning. Use these practical tips to maintain your comfort during unexpected heat waves or when your air conditioning is out of commission. Here’s to enjoying cool and comfortable travels, regardless of your destination!
