Why you need an air conditioner chemical wash:

Kills Bacteria & Mould

Moisture can build up in air conditioners, providing a conducive environment for mould and bacteria growth, which can harm those who are exposed to this contaminated air.

Luckily, an AC chemical wash removes and prevents mould and bacteria buildup, leading to smoother airflow and reduced condensation!

Better Air Quality

Poorly maintained air conditioning units can raise your risk of “sick building syndrome", irritate your respiratory system and ramp up allergies.

An aircon chemical wash service properly cleans your system, including eliminating 99.9% of harmful bacteria that build up inside your air conditioner!

Removes Any Foul Smell

A foul smell from your air conditioner is a huge indicator that something is not right - there might be bacteria growing on the air filter, or a small animal might have died in there.

Regardless, a chemical wash removes bacteria and also effectively eliminates lingering malodours, whether your air conditioner is new or old.

Extends Air Conditioner Lifespan

Accumulation of dust and grime can clog the whole aircon unit, leading to excessive wear and tear of the air conditioner parts and other complications, like water leakage.

An aircon chemical wash not only cleans but also shields the metal components of your air conditioning system against rust and corrosion.
