Step by step for cleaning

clean the filters

The function of these is to filter the air and prevent bacteria and other microorganisms from proliferating and damaging the operation of the equipment. A dirty filter reduces the efficiency of the appliance and is the first cause of the expelled air smelling bad.

The filters are located in the internal part of the split, behind the grille. For cleaning you will have to remove them. If it is a maintenance cleaning, it will be enough to use a vacuum cleaner to remove dust and some traces of dirt. For a more thorough spring cleaning, however, ideally rinse them with warm water and dry them in the shade before putting them back.

Air conditioners expel water due to condensation that collects in the drain pan. When this water remains stagnant - due to a bad slope in the hose - it can cause bad odors and facilitate the growth of bacteria and fungi.

Blowing hard through the tube can be a simple solution, however it is not something that is recommended for all devices. In addition, in centralized installations it is usually difficult to access it. turning it to heat mode for a few minutes could be another solution.

Clean the outside of the unit
