Aircon Chemical Overhaul Service
An aircon chemical overhaul service is a deep and intensive cleaning process that involves full dismantling of the air conditioner’s indoor unit. Unlike regular servicing or chemical wash, a chemical overhaul cleans every internal component using specialised chemical solutions to remove thick dirt, grease, mould, bacteria, and sludge buildup. This service is recommended when the air conditioner has serious cooling issues, water leakage, bad odour, or has not been properly maintained for a long time. A chemical overhaul helps restore the aircon to near-original performance and ensures long-term reliability.
