Like all the other electronic accessories, portable air conditioners also require protection so that the water cannot come in contact with the wires or any other electronic components.

Water is the biggest enemy of electronic components, and below is a brief explanation of what conditions rain can cause to damages to a portable air conditioner.

Internal components can be damaged

The portable air conditioner includes a drainage mechanism that allows the unnecessary moisture to flow out of the unit through various components through self-evaporation or by the components such as water collection tanks or a drainage hose.

If the rainwater got stuck in the unit and its components remain submerged in the water, it will damage the internal components and eventually fail them completely. In the worst case, the unit can catch fire if the electronic components contact the water. 

Dirt and water can form a coating

If the air conditioner is not maintained periodically, dust and debris can accumulate in the unit. When the water enters that unit, it forms a mixture, and this mixture can form a solid coating around the coils, tubes, and pipes.

This will block the coils from absorbing heat from the indoor environment leading to less effective and bad cooling performance. The mud should be removed as soon as possible because it can put a heavy load on the compressor, which can result in overheating the unit as well.

  • The first recommendation is to place the unit under a shade so that the rain cannot get close to the unit.
  • Secondly, always prefer to install the unit above the ground in an elevated area.
  • Your air conditioner unit should also be installed above the rainwater line on a wall or a stand so that the water can’t reach it from the surface.

Cover the AC Outdoor Unit:

  • If there is a forecast about the rain or storm, cover the air conditioner’s outdoor unit with a plastic sheet of canvas.
  • The debris can be there in the air conditioner but if you put a cover on the unit, it will prevent water from entering the unit and mixing with the dirt or debris.
  • If the rain is immense, put adhesive tape around the unit to ensure that the unit cannot be uncovered due to huge rain or storm.

Keep the Unit OFF During the Rain Storm:

  • Keep your air conditioner OFF during the rain because the rain can cause major damages only if it is in running condition.
  • It is recommended to unplug the unit and make sure that the air conditioner is not connected to any power source.
  • If there is an electricity outage due to the rain, never plug in the power cord to the electric source even if the rain has stopped because sudden surges of the electricity can also cause damages.

Install the Air Conditioner at a Clear Spot:

  • Never install the unit totally under trees or bushes because this will increase the ratio of dirt and debris.
  • Cut down the bushes especially the ones that are dried because dry sticks can cause major damages if they get inside the air conditioning unit.

After the Rain, Inspect the Unit Before Turning it ON:

  • Never turn the unit ON, immediately after the rain stops.
  • Check the unit thoroughly to ensure there are no damages.
