Used the split type AC after a few months of hiatus (used the heater function around winter, but essentially a year since I used the cooling function) but an odor comes out. I'm worried it might be mold from somewhere inside the the unit which could be potentially dangerous. Cleaned the detachable filters for dust, but the smell is still there.
Any simple solutions you can recommend such as cleaning solutions and the like? Its a relatively new unit, only used it for a year so I am not keen on having it serviced if it isn't necessary.
