How to Clean Your RV Air Conditioner

Keep Your RV A/C in Optimal Working Condition

Maintaining your RV air conditioner in peak condition is essential for enjoying a comfortable and pleasant travel experience, especially during those hot summer months. Regular cleaning ensures that your air conditioner operates efficiently, provides cool air, and has a longer lifespan. Here’s a comprehensive guide on how to clean your RV air conditioner to keep it in optimal working condition.

Step 1: Gather Your Cleaning Supplies

Before you start, make sure you have all the necessary cleaning supplies. You will need:

  • Screwdriver
  • Soft brush
  • Vacuum cleaner with a soft brush attachment
  • Mild soap or detergent
  • Water
  • Clean cloths
  • Fin comb (optional, for straightening the fins)

Step 2: Turn Off the Power

Safety first! Ensure that your RV is disconnected from the power source. Turn off the air conditioner and unplug your RV from the shore power. If your unit is connected to a generator, turn it off as well.

Step 3: Remove the Air Conditioner Cover

Using a screwdriver, remove the outer cover or shroud of the air conditioner. This cover is usually held in place by a few screws. Be gentle to avoid damaging the cover or the unit.

Step 4: Clean the Air Filters

The air filters are crucial for trapping dust and debris. Over time, they can become clogged, reducing the efficiency of your air conditioner. Remove the filters and wash them with warm, soapy water. Rinse thoroughly and let them dry completely before reinstalling. If the filters are damaged or excessively dirty, consider replacing them.

Step 5: Clean the Evaporator and Condenser Coils

The evaporator and condenser coils can accumulate dust and dirt, which hinders the cooling process. Using a soft brush or a vacuum cleaner with a brush attachment, gently clean the coils to remove any debris. Be careful not to bend the fins. If the fins are bent, use a fin comb to straighten them out. 

Step 6: Clean the Fan Blades

Dust and grime can also accumulate on the fan blades, affecting their performance. Use a soft brush to gently clean the blades. Wipe them down with a damp cloth to remove any remaining dirt.

Step 7: Inspect and Clean the Drain Pan and Drain Line

The drain pan collects condensation from the evaporator coils, which then drains out through the drain line. Check the drain pan for any signs of mold or blockage. Clean the pan with soapy water and ensure the drain line is clear. You can use a pipe cleaner or a small brush to remove any obstructions in the drain line.

Step 8: Reassemble the Unit

Once everything is clean and dry, reassemble the air conditioner. Replace the air filters, secure the cover, and make sure all screws are tightened properly.

Step 9: Test the Air Conditioner

After reassembling, reconnect your RV to the power source and turn on the air conditioner. Check if it’s operating smoothly and efficiently. Listen for any unusual noises and ensure that the airflow is strong and consistent.

Additional Tips for Optimal Performance

Regular Maintenance

Clean your RV air conditioner at least once every season to keep it running efficiently.

Check for Leaks

Inspect the unit for any signs of refrigerant leaks. If you notice a decrease in cooling performance or hear a hissing sound, contact a professional for repairs.

Cover the Unit

When your RV is not in use, cover the air conditioner to protect it from dirt and debris.
