Beat the Heat with Smart Cooling: Should You Add A/C to Your Camper Van?

Why Consider an A/C?

• Comfort & usability: A/C brings immediate relief—especially during sweltering summer nights—making the van livable even in peak heat.
• Resale value: An A/C-equipped camper often commands a higher resale price.
• Dual-purpose advantage: Our slim, 12-V units double as ventilators—they’re efficient, user-friendly, and among the quietest on the market.
• Humidity control: A/C doesn’t just cool—it reduces humidity, protecting the interior finishes, electronics, and even preventing mold in hidden corners.

What to Think About Before Installing

An air conditioning unit is one of the most power-hungry additions you can make to a camper van, so planning is key. Traditional 120V RV A/C systems can draw as much as 1,700 watts, which puts heavy demands on your electrical setup. Newer 12V A/C models are more efficient—some using up to 70% less power—but they still require serious energy management.

Battery capacity is often the biggest limitation. For example, a 1,200-watt unit can consume about 50 amp-hours every hour it runs. A typical 200Ah battery would only keep the system running for around four hours, and that’s without powering anything else in the van. To make the system practical, you’ll need a much larger battery bank paired with robust charging options. Solar panels can help extend autonomy, but they need to be sized appropriately to keep up with the demand.

It’s also important to think about how cooling integrates into the rest of your van. Good insulation, reflective window coverings, and proper ventilation can reduce how hard your A/C has to work. Finally, remember that installing an A/C isn’t just about dropping in the unit itself—it involves bigger electrical components, additional wiring, safety fuses, and overall load management. All of this adds complexity and cost to the build, but when done properly, it creates a reliable and comfortable system that can keep up with your adventures.

How Nav Camper Handles It

At Nav Camper, we tailor each build to support A/C effectively and sustainably:

• Upgraded battery bank: We double the capacity—installing 2×460 Ah (920 Ah) lithium-ion batteries, compared to our standard 400 Ah banks.
• Enhanced charging: We include a secondary charging system totaling 80 Ah/h, ensuring efficient recharge of the expanded battery bank even off-grid.
• Holistic build design: We ensure your A/C installation works seamlessly with your electrical system and insulation package.
• Versatility: Since our A/Cs can also operate as high-powered ventilators, you don’t always need to run full cooling mode—this saves energy while still keeping airflow inside
• Future-proof setup: Even if you don’t use A/C all the time, the larger battery and charging system provide greater autonomy for everything else—induction cooking, laptops, lights, or Starlink internet.

These upgrades can elevate total investment—sometimes up to $10,000—but they also transform your camper into a reliable, comfortable, off-grid haven.

Final Thoughts

Adding an A/C unit isn’t just about cooling—it’s about transforming your van into a comfortable, all-season retreat. If you value comfort and plan to venture off-grid, it’s an investment worth making—but only when paired with the right system components.

At Nav Camper, we don’t just add an A/C—we engineer the power, autonomy, and comfort to make it work reliably.
