What is a chemical wash for aircon?

Aircon chemical overhaul

A chemical wash for an AC is a deep cleaning process that uses specially formulated chemical solutions to thoroughly clean the internal components of the air conditioning system. Unlike standard cleaning methods that involve basic dusting and water rinsing, a chemical wash targets stubborn dirt, mold, and grease that accumulate over time, ensuring the unit operates efficiently and hygienically.

Why Is a Chemical Wash Necessary?

Over time, AC collect dust, bacteria, mold, and other pollutants from the air. While routine maintenance like cleaning filters can help, deeper problems can develop in the system's internal components, such as the evaporator coils, condenser coils, and drainage pipes. These problems can lead to:

• Reduced cooling performance

• Bad odors

• Higher electricity bills

• System breakdowns

• Water leakage

• Poor indoor air quality

A chemical wash helps restore the AC efficiency, prolongs its lifespan, and improves the quality of air circulated.

What Components Are Cleaned During a Chemical Wash?

During a chemical wash, a technician will usually disassemble the AC to access key components. The parts typically cleaned include:

1. Evaporator Coil

   This coil absorbs heat from the air in your room. A dirty coil reduces the cooling efficiency and can freeze up.

2. Condenser Coil

   Located in the outdoor unit, this coil releases the heat absorbed inside. It can get clogged with dirt and outdoor debris.

3. Air Filters

   These trap dust and other airborne particles. While filters are easier to clean, during a chemical wash they are thoroughly soaked and disinfected. View more

4. Fan Blades and Blower Wheel

   These parts circulate air. Dust buildup can cause noisy operation and reduced airflow.

5. Drainage System

   This removes condensation from the system. Blockages can cause leaks and mold growth.

6. Outer and Inner Panels

   All casing parts are cleaned to remove surface grime and mildew.

The Chemical Wash Process

1. Disassembly

   The technician begins by turning off the power supply and carefully disassembling the air conditioner to access internal parts.

2. Application of Chemicals

   A chemical solution (usually alkaline-based or mild acid-based) is applied to the dirty components. This helps dissolve grime, grease, and microbial growth.

3. Soaking and Scrubbing

   Components may be soaked in chemical baths. Technicians scrub coils, fans, and filters to remove stubborn deposits.

4. Flushing

   After the chemical has worked on the contaminants, all parts are thoroughly flushed with clean water to remove any residue.

5. Drying and Reassembly

   Components are dried, and the unit is reassembled. Some technicians may also apply an anti-bacterial spray to help prevent future mold growth.

6. Testing

   The AC is turned on and tested to ensure it’s functioning correctly.

How Often Should a Chemical Wash Be Done?

It is generally recommended to perform a chemical wash once every 1 to 2 years, depending on the environment and usage. In dusty or humid areas, or for units in commercial settings, more frequent cleaning may be necessary.

Benefits of a Chemical Wash

• Improved Efficiency: Clean components allow the system to cool more effectively.

• Energy Savings: An efficient system consumes less electricity.

• Extended Lifespan: Reduced wear and tear helps the unit last longer.

• Better Air Quality: Mold and bacteria removal leads to cleaner indoor air.

• Prevention of Leaks and Odors: A clean drainage system prevents water build-up and unpleasant smells.

Conclusion

A chemical wash is an essential part of AC maintenance that goes beyond surface cleaning. It involves disassembling the unit and using chemical solutions to clean key components deeply. This process helps maintain the air conditioner’s performance, improves energy efficiency, and ensures a healthier indoor environment. For homeowners and businesses alike, scheduling regular chemical washes can prevent costly AC repairs and extend the life of their cooling systems.
