Give Your RV Air Conditioner a Checkup Before Summer Hits
As warmer weather arrives and camping season kicks into high gear, a well-maintained RV air conditioner can make all the difference. Whether you're heading north for a mountain escape or settling in for a sunny extended stay, keeping your RV cool ensures every adventure stays comfortable.
At Sun Outdoors, we know the best trips start with peace of mind. That's why we're sharing essential RV air conditioner maintenance tips to help your AC run efficiently all season long—so you can focus on relaxing, exploring, and enjoying the journey.
Why RV Air Conditioner Maintenance Matters
Routine RV AC maintenance does more than keep temperatures comfortable—it helps prevent costly repairs, improves energy efficiency, and extends the life of your system. Catching small issues early can save you from unexpected breakdowns, especially during peak summer travel.
6 Essential RV Air Conditioner Maintenance Tips
1. Clean or Replace Your Air Filters
Clean air filters are key to strong airflow and better cooling performance. Check your RV AC filters regularly—especially after long trips or dusty campground stays. Wash reusable filters with mild soap and water, and replace disposable ones as needed.
Tip: If allergies are an issue, consider an electrostatic filter to capture smaller particles.
2. Inspect the Rooftop Shroud
Your AC's rooftop shroud protects critical components and supports proper airflow. Remove debris like leaves, dirt, or nests, and check for cracks or loose bolts. Replace damaged shrouds right away to avoid road hazards or weather exposure.
3. Check the AC Gasket for Leaks
The gasket between your air conditioner and roof creates a watertight seal. If it looks dry, cracked, or compressed more than 50%, it's time to replace it. A worn gasket can lead to leaks and costly water damage inside your RV.
4. Listen to the Fan and Motor
Turn on your AC and listen closely. Grinding, rattling, or humming noises may indicate motor or fan issues. Make sure the fan blade spins freely and isn't obstructed—smooth, quiet operation is what you're aiming for.
5. Clean the Coils Once a Year
Even with clean filters, dust and grime can build up on the evaporator and condenser coils. Annual coil cleaning improves cooling efficiency and airflow. For best results, hire a certified RV technician who can also straighten bent cooling fins.
6. Use the Right Power Supply
Your RV air conditioner needs sufficient power to run properly. Always use at least 30-amp service, and opt for 50-amp hookups when available. Insufficient power can strain the motor, reduce cooling capacity, and shorten the unit's lifespan—another reason Sun Outdoors resorts with full hookups are a smart choice.
