Aircond Chemical Wash KL | Deep Coil Cleaning Service

Q: What's the difference between chemical wash and chemical overhaul?

A chemical wash cleans the coil in place using chemical spray and rinse. A chemical overhaul dismantles the entire indoor unit for a more thorough soak-clean of every component.

Q: How often should I get a chemical wash?

Once a year is recommended for most residential units. Units in dusty or greasy environments (kitchens, workshops) may need it every 6 months.

Q: How much does chemical wash cost in KL?

Chemical wash typically costs RM120-RM180 per wall-mounted unit. Ceiling cassette and ducted systems cost more due to complexity.

Q: Will chemical wash fix my aircond's musty smell?

Yes, in most cases. The musty smell comes from mould and bacteria on the coil and drain pan, which chemical wash effectively removes.

Q: How long does a chemical wash take?

About 45-60 minutes per unit. We recommend not using the aircond for 1-2 hours after to let everything dry properly.

Why You Need Professional Aircond Chemical Wash

Over time, dust, grease, and mould build up on your evaporator coil so thickly that regular brushing and water cleaning can't remove it. This insulating layer of grime blocks heat exchange, forcing your aircond to work harder while delivering weaker cooling. You'll notice higher electricity bills and a musty smell. A chemical overhaul goes even deeper, but for most units, a chemical wash is the right balance of thoroughness and cost. Homeowners across Old Klang Road and surrounding areas trust us for this service.

Our Aircond Chemical Wash Process

Every job follows a structured process to ensure consistent, high-quality results.

1

Unit Assessment

We inspect the coil condition to confirm a chemical wash (vs. chemical overhaul) is appropriate for the level of buildup.

2

Component Protection

Electrical components and surrounding walls are covered with protective sheets to prevent chemical or water damage.

3

Chemical Application

Professional-grade alkaline/acidic coil cleaner is sprayed onto the evaporator coil and left to dissolve stubborn deposits.

4

High-Pressure Rinse

The coil is rinsed thoroughly with pressurised water to flush out dissolved dirt, mould, and chemical residue.

5

Reassembly & Test

All components are reassembled, the unit is powered on, and cooling output is verified.
