Air conditioning is a game-changer for comfort on the road—but like every bit of kit on your campervan, it needs the right care to stay efficient and long-lasting. Whether you’ve got a roof-mounted unit or a portable setup, protecting your AC system during and between trips is key to getting the most from your investment.
💨 1. Clean Filters Regularly
Your air conditioning filter traps dust, pollen, and airborne particles while you cool off. But over time, that filter gets clogged—and a dirty filter means:
👉 What to do: Clean or replace your filters every couple of weeks when in use. Most filters are easy to remove and rinse with lukewarm water.
🔍 2. Check for Leaks and Seals
Small air leaks around your AC unit can let moisture in or cool air out. Over time, this leads to:
👉 Top tip: Inspect roof seals annually and look for any gaps around unit casing. A little silicone sealant can prevent big problems later.
🛠️ 3. Don’t Ignore Strange Noises
Rattles, buzzing, or whining sounds could point to worn bearings or loose parts. The longer you leave it, the more damage can occur.
👉 Quick check: Turn off the AC and restart it. If the noise returns, it’s best to get a technician to take a look before damage gets expensive.
🧊 4. Avoid Running It Continuously
While modern units are efficient, constantly running your AC on max can overwork the compressor and drain your leisure battery.
👉 Better way: Use a programmable thermostat or timer switch where possible to give the unit breaks while maintaining comfort.
🛡️ 5. Use a Campervan Cover During Storage
Here’s a tip many vanlifers overlook: your air conditioning unit is exposed to sun, rain, ice, salt, and debris all year round—even when the van’s off the road. This constant exposure leads to:
-
UV damage to external AC casing
-
Moisture corrosion on coils or vents
-
Dirt build-up that clogs cooling fins
👉 Solution: A high-quality campervan cover protects not just your paintwork, but also your rooftop AC system.
At UK Camping & Leisure, our motorhome and campervan covers are designed for year-round protection. Breathable, waterproof, and UV-resistant, they help keep your van (and your air con) in top shape.
🧼 6. Clean the Unit Exterior
If your air con is roof-mounted, dust, leaves, or bird droppings can block vents and reduce performance.
👉 Pro tip: Wipe down the outside unit at least once a season with a damp cloth and mild detergent. Avoid pressure washers—they can force water into the electronics.
🧊 Final Thoughts
A little maintenance goes a long way when it comes to campervan air conditioning. From simple filter cleans to full winter cover protection, these small habits can help avoid costly repairs and ensure you stay cool for years to come.
And when it’s time to park up for the off-season? Protect your investment—inside and out—with a campervan cover that does more than keep out the rain.
