Discover the "Hygiene Gap" in aircon maintenance. Learn how regular servicing differs from specialized cooling coil hygiene with Cleanhale™.

Every time you turn on your air conditioner, air cycles directly across the cooling coil - the cold, damp surface inside your split unit.

While most homes and offices get regular aircon servicing, basic functional checks and washed filters don't tell the full story. There is a critical distinction between basic functional maintenance and deep cooling coil hygiene.

We call this distinction The Hygiene Gap.

Why the Cooling Coil Needs Special Care

The cooling coil operates in a dark, humid environment. As warm air meets cold metal, condensation forms. Over time, this moisture combines with airborne particles to create a baseline for biofilm - a structured layer of microorganisms that sticks firmly to metal fins.

• Dust filters aren't enough: Filters capture large dust particles upstream, but fine microbial matter still passes through to the damp coil, accumulates and ultimately grows.

• Impact on performance: Biological buildup on finned cooling coils can reduce thermal transfer efficiency and restrict airflow.

• Recolonisation: Microbes naturally return over time, which is why coil hygiene should be an ongoing routine rather than a one-time fix.

Key Takeaway: Cleanhale™ is not a replacement for General Service or heavy chemical washes - it is a preventative hygiene upgrade designed to be added to your regular service schedule.

Scientific Rigor & Verified Performance

Cleanhale™ is engineered and manufactured in Germany to provide a dual chemical and hydromechanical cleaning action.

Testing conducted by TÜV SÜD PSB Pte Ltd demonstrates:

• Up to 99.9994% Reduction of bacterial buildup and microbial residue (tested against Pseudomonas aeruginosa under laboratory surface conditions).

• Up to 64.8% Reduction in yeast and mould counts (evaluated on split-unit coils under SS 554 snapshot standards).

Note: Cleanhale™ is a specialized hygiene treatment, not a regulated chemical biocide or permanent sterilizing agent. Performance varies based on system condition and operating environment.

Frequently Asked Questions

1. Does a general service clean the cooling coil?

General servicing focuses on functional checks, drainage clearance, and filter washing. Specialized coil hygiene requires a dedicated treatment added to the process. 

2. Is Cleanhale™ a biocide or disinfectant?

No. Cleanhale™ is a specialized cooling-coil treatment designed to mechanically detach and flush buildup, avoiding harsh biocide chemicals. 

3. How often should Cleanhale™ be applied?

We recommend adding Cleanhale™ to your General Service 1 to 2 times per year to maintain coil hygiene and prevent severe contamination.

How to close the Hygiene Gap in real life?

Upgrade your routine aircon maintenance by asking your technician a single question:

"Filters and general dust removal are complete, but has the evaporator coil been hygienically treated?"
