The tech showed up with all the right tools and parts necessary for the job. They also done a complete aircon chemical wash. He had my system up and running again within 2 hours!

What is a Aircon Chemical Washing?

General aircon servicing 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.

Aircon chemical wash 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 from Aircond Specialists
