Portable units: Turn off your AC before cleaning. Remove the grills or coils and use a soft brush to dust off the coils. Clean the drain pan using warm water and dishwashing soap. Pour the solution down the drain. Then, pour clean water to rinse the mixture off the drain. Repeat until the water runs clear. Wipe the exterior of the AC using a cloth dampened with the same mixture. Use another clean cloth to wipe off the excess. Let all components dry completely before plugging back in.
Split-type air conditioners: Before cleaning your split type of unit, set the AC in fan mode for about 40 minutes to help the moisture evaporate. Then, unplug the unit and dismantle it for cleaning. Get a large bag and lay it on the floor to catch falling dirt and dust from the AC. Remove the front panel and unfasten the filters. Dust off the filters and wash them with soapy water, if possible. Use an air blower in the lower setting to clean the cooling fins. Then, use a no-rinse evaporator spray or an anti-fungal spray for a deeper clean.
Window-type models:Turn off your window-type air conditioner and remove it from the wall or window. Remove the filter and clean it using warm, soapy water. Remove the unit's case and wipe it down with a microfibre cloth dampened with soapy water. Use a vacuum with a brush attachment to remove dust and dirt from the unit. Then, spray soapy water in the interior and use a soft bristle brush to remove dust and grime from the fins. Leave everything to dry before reassembling.It is still best to consult your manufacturer's manual for more comprehensive advice on cleaning your air conditioner as cleaning processes may vary, depending on the make, brand, type and size of your air conditioner.
