Professional Aircond Chemical Wash with Free Gas Top-Up

What Is an Aircond Chemical Wash?

An aircond chemical wash is a thorough deep-cleaning procedure that goes far beyond a basic filter wipe. During a chemical wash, our senior technicians fully dismantle your air conditioning unit to access the evaporator coil, blower wheel, drainage pan, and internal components that accumulate dirt, mould, and bacteria over months of operation in Malaysia’s humid tropical climate.

Unlike a standard cleaning which only addresses surface-level dust, a chemical wash uses professional-grade alkaline coil cleaner and antibacterial solution to dissolve stubborn grime, kill 99.9% of bacteria and mould spores, and restore your fan coil unit (FCU) to near-factory condition. The result is noticeably colder air, improved airflow, lower electricity consumption, and healthier indoor air quality for your family.

Our Complete Chemical Wash Process

Step 1: Pre-Wash Inspection

Before we touch a single screw, our technician inspects your aircond’s current performance. We check the cooling temperature differential, listen for unusual noises, inspect the drainage for blockages, and measure refrigerant pressure using PSI gauges. This pre-assessment ensures we catch any underlying issues -such as a refrigerant leak or faulty capacitor -before they become costly repairs.

Step 2: Full Dismantling

Your wall-mounted unit’s front cover, air filters, blower wheel, and drainage pan are carefully removed. For ceiling and cassette units, additional panels and components are dismantled. We use the canvas method to protect your walls and floor from chemical runoff during the cleaning process.

Step 3: Chemical Coil Treatment

The exposed evaporator coil is sprayed with professional-grade alkaline coil cleaner that dissolves years of built-up grime, grease, and biological contaminants. The blower wheel is scrubbed individually, and the drainage pan is flushed with antibacterial solution to prevent future algae growth and water leakage. Every component is rinsed thoroughly with clean water.

Step 4: Reassembly and FREE Gas Top-Up

After all components are clean and dry, the unit is carefully reassembled. We then perform a FREE gas top-up -adding up to 10kg of R22, R32, or R410A refrigerant as needed to bring your system to optimal pressure levels. Finally, we run the unit and verify that cooling performance meets our quality standards.

When You Need a Chemical Wash

Not sure whether your aircond needs a chemical wash or just a standard cleaning? Here are the signs that a chemical wash is overdue:

• Your AC is blowing warm or less cold air despite being set to low temperature
• Foul or musty odour coming from the vents, especially when the unit first starts
• Water leaking from the indoor unit, often caused by a blocked drainage pan
• Visible mould or dark residue on the air outlet or filter
• Higher-than-normal electricity bills suggesting the compressor is working harder to compensate for reduced efficiency
• It has been 6-12 months since your last chemical wash

If you are experiencing any of these symptoms, a chemical wash will likely resolve the issue. For persistent problems like compressor noise or electrical faults, our aircond repair service can diagnose and fix the root cause.

Benefits of Regular Chemical Washing

Scheduling a chemical wash every 6-12 months delivers measurable benefits for Malaysian homeowners:

1. Improved cooling efficiency -a clean evaporator coil transfers heat up to 30% more effectively
2. Lower electricity bills -when your compressor does not have to overwork, energy consumption drops noticeably
3. Better indoor air quality -removing mould, bacteria, and dust allergens from the blower and coil
4. Extended unit lifespan -regular deep cleaning prevents corrosion and component wear
5. Fewer breakdowns -proactive maintenance catches small issues before they become expensive repairs
6. Consistent airflow -a clean blower wheel delivers proper CFM (cubic feet per minute) output
