Is mould in the AC really dangerous or is it cleaning-company marketing?

What is really happening

Scepticism is healthy, so here is what the sources say, not the companies. WHO concludes that indoor dampness and mould significantly raise the risk of respiratory symptoms, allergies and asthma. A meta-analysis of 16 studies finds ~33% higher risk of new asthma in damp homes and ~73% higher where there is mould odour – the odour being the sign of active growth. Your unit at 7 years without sanitising is a permanent source of spores and fungal fragments thrown into the room at every start-up, at concentrations tens of times above background. That nobody is ill now is good news, not proof the exposure does not matter – the effects are statistical and cumulative, especially in children.

What we do on site

1. We come, open the unit and let you look for yourself – a 7-year-old LG that has never been sanitised is more convincing than any statistic.
2. Collection cover under the unit; cleaning solution; pressure wash in place of evaporator, roller, pan.
3. Sanitising solution on the clean surfaces.
4. Outdoor unit, washed in place.
5. See current rates on the Prices page.

What you can do yourself

• Do the test yourself: unit off at the breaker, remove the filters, shine your phone light on the roller behind the grille – if you see dots or a grey layer, you have your answer.
• Keep doing the filters every two weeks, that is good.
• Add 'Fan' for 20 minutes before shut-off.

What NOT to do

Prevention

A unit cleaned annually is a mould exposure of zero. Rhythm: once a year, in spring; filters every two weeks; drying on 'Fan'.
