How Long Does a Chemical Wash Take?

A single wall-mounted unit chemical wash takes approximately 45–90 minutes depending on the level of soiling. A heavily neglected unit that has not been serviced for 2 or more years may take up to 2 hours. Ceiling cassette units typically take 90–120 minutes due to their larger coil surface area and the additional work required to access the unit through the ceiling panel.

How Often Should You Get a Chemical Wash?

For most Malaysian homes, once every 12 months is the recommended minimum. Units in high-humidity areas such as Batu Caves, Selayang, coastal properties, or zones near active construction benefit from servicing every 8–10 months. Units in air-conditioned offices or commercial spaces used 10–12 hours daily should be chemically washed every 6 months.
