Understand the system

Understanding how your RV air conditioning system works is the first step to maximising its efficiency. The compressor compresses the coolant into steam, then the condenser removes the heat and condenses the steam into a liquid. The evaporator coil then extracts the heat from the return air to expand and evaporate, resulting in cold air being produced and spread throughout the RV.

The functionality of the system will help you know what to adjust to bring fresh and relaxing air, as well as how much power the system uses and the correct power level that will allow it to function to its fullest. For example, RV air conditioners are known for using low voltage, but it is recommended to have 115V AC per device to ensure your AC can function to its maximum capacity.

It is also important to understand the limitations of your RV AC. For example, in most cases, RV air conditioners are not functioning well, not because they are faulty, but because the owner has failed to understand their limits. According to statistics, most air conditioners fail to function because of dirty filters, pollutants, and dust. Therefore, it is important to regularly clean your filters and ensure the return air is free of contaminants.

Clean filters regularly

To make your camper AC more efficient, it is important to clean the filters regularly. Dirty filters are one of the main reasons for poor cooling in an AC system. By keeping your filters clean, you can ensure that your AC unit is working at its optimal level and that you are getting the most efficient cooling performance.

It is recommended to clean your camper AC filters at least once every two months. However, it is a good practice to clean them whenever you feel that the air being produced is not clean or when you notice a decrease in cooling performance. When cleaning the filters, use lukewarm water with a mild detergent. Be sure to rinse the filters thoroughly and allow them to dry completely before reinstalling them. You can also use an air compressor to blow off any remaining dust or debris.

In addition to regular cleaning, it is important to inspect the filters for any signs of damage or wear. Over time, filters may develop tears or holes that can affect their effectiveness. If you notice any damage, be sure to replace the filters with new ones.

Another factor to consider is the type of filter you are using. There are different types of filters available, such as pleated filters, washable filters, and disposable filters. Each type has its own advantages and disadvantages, so it is important to choose the one that best suits your needs. Pleated filters, for example, have a larger surface area that can trap more particles, but they may need to be replaced more frequently. Washable filters can be cleaned and reused multiple times, but they may not be as effective at trapping small particles. Disposable filters are convenient and easy to replace, but they can be more expensive in the long run.

When cleaning or replacing your filters, it is also a good opportunity to inspect the rest of your AC unit for any signs of dirt, dust, or debris buildup. Ensure that the return air path is clear and free of any obstructions, as this can also impact the efficiency and performance of your AC unit.

By following these simple steps and maintaining your filters regularly, you can help improve the efficiency of your old camper AC and ensure that it provides you with reliable and effective cooling performance.

Ensure sufficient power

To ensure your camper AC is running efficiently, you need to make sure it has sufficient power. Here are some tips to help you achieve this:

  • Understand the power requirements: Know how much power your AC unit needs to function effectively. Most RV air conditioners use low voltage, but it is recommended to have 115V AC per device for optimal performance.
  • Minimize the use of heat-generating appliances: Appliances such as cookers, toasters, ovens, and microwaves generate a lot of heat, which can affect the performance of your AC. Try to limit their usage, especially during the hottest parts of the day.
  • Add extra fans: If your AC struggles to cool your RV, consider adding fans inside your rig to improve air circulation and help distribute the cool air more effectively.
  • Use LED lights: LED lights consume significantly less electricity than regular bulbs and generate less heat, so they won't interfere with your AC's performance.
  • Park in the shade: Whenever possible, park your RV in a shaded area to avoid direct sunlight, which can increase the temperature inside your RV and make it harder for your AC to cool the space.
  • Maintain your AC unit: Regular maintenance is crucial to ensuring your AC unit is running efficiently. Clean the filters at least once every two months, and always ensure they are unobstructed by dirt or other contaminants.
  • Check for leaks and gaps: Seal any leaks or gaps around windows, doors, and vents to prevent cool air from escaping and warm air from entering. This will reduce the workload on your AC unit.
  • Upgrade to a more efficient AC unit: If your RV is more than 10 years old, consider upgrading to a newer, more energy-efficient air conditioning unit. While the initial cost may be high, you will likely save money in the long run through reduced energy consumption.
