How to maintain an RV air conditioner to avoid needing to repair it

The answer is simple, to maintain an RV air conditioner unit, you will need to clean it more or less frequently. It’s not exactly rocket science, but it still has to be done; remember that the cleanliness of your trailer air conditioner is essential to ensure optimal operation!

Start outside your RV. You will need to repeat these operations at least once a year, or even more depending on your use. To do this, remove the air conditioning cover and remove any debris that may have accumulated: insects, dead leaves, dust, etc. To make cleaning easier, you can use a shop vacuum or a compressed air cleaning system.

Once properly cleaned, take the opportunity to inspect the seal located between the front and rear compartments; If it shows signs of wear, then it should be replaced without delay. If necessary, you will also need to lubricate the engine, if you notice a hole in it; a few drops of SAE 20 oil will do the trick.

Once you’ve put the outer cover back on, move inside your trailer. Remove the inner cover and remove the filters; these can be washed with soapy water. The more you use your air conditioner, the more often you will have to clean it; but in this way, you will ensure that it functions optimally for many years to come!

Make sure you clean the air conditioner’s filters, as well. For an air conditioner, the filter is as important as the oil for an engine. Its periodic maintenance is essential: a clogged filter reduces the airflow of the device, a cause of major damage to its compressor.

  • Wash the reusable filters and then rinse them with lukewarm water, making sure they are completely dry before reinstalling them. If you have disposable devices instead, you just need to replace them.
  • If you have a room air conditioner or central unit without ducts, clean the box grille covering the filters; make sure that nothing obstructs the distribution of the air (curtains, furniture, etc.).
  • The frequency to be observed depends on the manufacturer’s instructions, but also on the degree of exposure of the device to dust (depending on the activities in the house, the presence of animals, etc.).

Why maintain your air conditioner?

Preventive maintenance is very important. It contributes to:

  • optimal performance of your device
  • saving energy – and cost!
  • extended service life
  • healthier air, eliminating bacteria and preventing mould.

Is your air conditioner not working? It may be lacking in freon. Otherwise, go to your dealership or to a technician specializing in trailer air conditioning maintenance who will quickly find the problem and resolve it. But don’t wait until the last minute to have your air conditioning system repaired!

The bottom line

If you still can’t manage to find the source of the issue, it may be the right time to go to an authorised dealership or to contact a  technician specializing in trailer air conditioning maintenance who will quickly find the problem and resolve it.
