Frequently Asked Questions

Our chemical wash includes full indoor unit dismantling, chemical cleaning of evaporator coils, blower fan cleaning, drainage flushing, reassembly, and a FREE gas top-up (up to 10 kg of R22, R32, or R410A refrigerant). We also test the unit's cooling performance before leaving.

Standard cleaning covers filter washing, cover wiping, and basic blower cleaning without dismantling the unit. Chemical wash involves fully dismantling the indoor unit, deep-cleaning the evaporator coils with specialised chemicals, flushing the drainage system, and includes a free gas top-up. Chemical wash is recommended for units that haven't been serviced in 6+ months or are blowing warm air.

In Malaysia's tropical climate, we recommend standard cleaning every 3-4 months and a chemical wash every 6-12 months for residential units. Commercial units — especially in F&B outlets — should be chemically washed every 3-6 months due to higher usage and grease exposure.

Yes. Every chemical wash and repair booking includes a FREE gas top-up of up to 10 kg (R22, R32, or R410A). Most competitors charge RM 80-150 separately for this. We include it because topping up gas after a chemical wash ensures optimal cooling performance.
