Which should I choose? Aircon Chemical overhaul or normal chemical cleaning?
Aircon chemical wash simply means the cleaning of a unit with a chemical solution. The motherboard of the fancoil will be wrapped with a water proof material to prevent water damage to the motherboard, an inexperienced technicians might not handle this well.
Chemical overhaul means a full clean of your unit. The gas will be locked, this will be done by climbing out to the condensing unit and switching it off. Our technicians will then proceed to do a full dismantling of the fancoil and this allows us to clean it thoroughly on both sides!
The biggest difference? A chemical washing cleans the surface and front end of the fancoil but a chemical overhaul cleans the whole fancoil!
Generally you don’t have to do schedule a time to do chemical overhaul. Your technicians will be able to advise you that they will have to do chemical overhaul the next trip. Or sometimes they will be able to do for you on the spot. You will only need to do Aircon chemical overhaul on these 2 conditions. Either your Aircon evaporator coil is clogged and Air is not blowing smoothly. Or water is leaking from the back tray. For normal Aircon users. You generally only need to do once a year or once every 2 years. Nonetheless, do take note that when the time comes for you to do chemical overhaul. Do not opt for normal chemical cleaning instead. It will be a waste of your money.
