What is Aircon Chemical Overhaul?

Air conditioners must be serviced on a regular basis to guarantee that they can last for years. While basic servicing and maintenance is a smart way to keep it in good working order, it may not be enough in the long run.

Regular maintenance may assist in removing dirt from your air conditioner, but it may not be as efficient in removing the dirt buildup that has gathered and lodged in your condenser, filter, and evaporator coil. Furthermore, incorrect cleaning techniques may result in serious damage to internal components. This is when an air conditioner chemical cleaning or overhaul is required.

Aircon chemical cleaning is a vital procedure. Regular cleaning may contribute to the removal of some undesirable particles particularly on the aircon’s filters. Even so, the components have a lot of harmful biofilms that have collected over time along the condenser coils.

This biofilm is difficult to remove and can corrode and harm the internal components of your air conditioner, reducing its efficacy and performance. Thus, aircon chemical cleaning at least once every six months is recommended. Professionals may recommend an aircon chemical overhaul for your air conditioner if the chemical cleaning is insufficient to clean the system fully.

Aircon Chemical Overhaul is a deep cleaning service, which involves dismantling the entire aircon unit, cleaning the various aircon parts with chemicals, and flushing the entire unit with safe formulated chemicals to ensure any dust & dirt that is trapped within the aircon system is being flushed. Aircon chemical overhaul will help to restore and improve the air conditioning unit’s performance.
