What is a Chemical Cleaning?

General cleaning services can clean out dust and other particles inside a well-maintained air-conditioner. However, it might not be enough if the unit has not been cleaned for years or if the unit has been on standby for a long time.

The dust, materials, and other chemicals inside the unit might have hardened overtime and can’t be removed by just water and some soap even with the use of a compressor. It is during these situations that using a cleaning chemical to clean your AC becomes necessary.

It follows a similar process to the standard aircon cleaning that are used for air-conditioners. Instead of just water and soap, a chemical solvent is used in the mixture to remove hardened dust and materials in the vents or grease on the fan coil to restore the cooling effectiveness of the unit.

It is a cleaning method that will thoroughly clean your air conditioner's drainage, fan coil, and pipes to make it transfer heat and cold air more efficiently. Many have reported that their air conditioner operates like it’s brand new after a full chemical cleaning.

Safety Guidelines

Protective Containers

All chemicals used in our chemical wash service are stored inside protective containers that prevents the solvent from leaking out. It is to make sure that it won’t spread inside the household and may cause damage to other parts.

Safety Checks

The chemical wash process will involve safety checks before proceeding to the application of the chemical. Our technicians will be using the needed equipment and wearing the necessary gear to conduct the procedure safely. 

Safety Advice

People inside the house or office building will be advised to keep their distance from where the chemical wash is being done to avoid any untoward instances.

I availed of Coolbest Aircon installation services a few years back and when I asked for replacement parts for the unit recently, they supplied the needed parts right away. I also availed of their maintenance contract service which schedules two visits a year. Not only do they perform great work, they also come at the set time. They haven’t disappointed me up to this day. I would recommend Coolbest Aircon services to anyone having problems with their AC unit
