Troubleshooting Common RV Air Conditioner Cleaning Issues

Despite following the proper cleaning procedures, you may encounter some common issues with your RV air conditioner. Don’t worry, we’ve got you covered with some troubleshooting tips to help you overcome them.


If your RV air conditioner is not cooling enough, check the thermostat first to ensure that it is set correctly. If it is set correctly, you may have dirty air filters that need replacing. Dirty filters obstruct the airflow, leading to decreased cooling efficiency.


Replace the dirty air filters with new ones to ensure proper airflow, which will enable the unit to cool consistently and effectively.


If there is a water leak around your RV air conditioner, it might be due to a clogged condensate drain line. Condensate builds up over time and must be drained out via a tube to prevent water leaks.


Inspect the drain line and make sure it is not clogged. If it is clogged, use a wet/dry vac to remove any debris or dirt buildup from the tube. If the issue persists, you may need to call a professional to clean up the drain line.


If there is a strange noise coming from your RV air conditioner, it may be due to loose or worn-out parts. Commonly, the noise is due to a damaged fan or motor.


Inspect the fan and motor and ensure that they are securely fastened in place. If they are loose or damaged, consider replacing them or calling a professional to do so.

By following these simple troubleshooting tips, you can identify and solve some of the most common issues that RV air conditioner owners face. However, for more complex issues or if you are uncertain of what steps to take next, it is always best to call in a professional for help.

Maintenance Tips for RV Air Conditioner Cleaning

Regular maintenance is crucial in keeping your RV air conditioner in optimal condition. Here are some maintenance tips to follow:

  • Clean the filters: Clean the filters after every trip or season to remove dust, dirt, and debris. Dirty filters limit airflow and reduce the efficiency of the unit. Use warm, soapy water to clean the filters and allow them to dry completely before reinserting.
  • Clean coils: Dirty coils make it harder for the air conditioner to cool effectively and make it work harder than necessary. Clean the coils using a soft brush to remove dirt and debris. For stubborn buildup, use a commercial coil cleaner.
  • Keep the area around the unit clean: The area around the RV air conditioner should be kept clean and free of debris to prevent blockages and to allow for proper airflow.
  • Inspect the seals: Inspect the seals around the unit and ensure they are in good condition. Damaged seals can cause drafts, reducing the efficiency of the air conditioner.
  • Have it serviced regularly: Consider having your RV air conditioner serviced by a professional at least once a year. A professional can detect and fix problems before they become serious and extend the lifespan of your unit.

By following these maintenance tips, you can ensure that your RV air conditioner operates at its best, providing you with comfort and efficiency during all your travels.
