Maintenance and Cleaning of RV Air Conditioning System

RV air conditioners, like home air conditioners, need to be maintained, such as regular cleaning to see if the air conditioning filters are aging, etc. TKT reminds you to pay attention to regular maintenance of your RV air conditioner to give yourself a comfortable and refreshing environment.

Split-Type Air Conditioner Cleaning Method

1. Please clean the dust on the filter at the air intake of the air conditioner on time to improve the cooling effect and at the same time facilitate energy saving.
2. The RV air conditioning filter should be cleaned frequently to avoid accumulation of dust. When cleaning, please use a soft towel or sponge, dip it in water or non-corrosive neutral detergent to clean, and finally wipe it with water and a dry rag.
3. Do not use a soft towel or other sponge with dripping water when cleaning, to avoid water droplets penetrating the indoor electromechanical control and causing damage to the substrate, or even starting a fire.
4. Do not use hard brushes, steel balls, wire brushes, abrasives (e.g., toothpaste), organic solvents (e.g., alcohol, acetone, banana water, etc.), boiling water, or acid or alkaline items when cleaning, as this will damage the air conditioner of the RV.
5. Regularly clean the outside air conditioner, rinse the outside fan, the chassis of the outside air conditioner, and the visible parts in the left and right side fence holes of the outside air conditioner.
