Air Conditioning Units and Mould

Posted on: September 17th, 2018 by AC Direct

Mould can form in many places in both commercial and domestic environments. However, when mould forms inside an air conditioning unit it can be difficult to remove due to the multiple components that make up the unit. In the latest post from Air Conditioning Direct, we take a look at the effects of mould in an air con unit.

Those with a sensitivity to mould can often feel various symptoms should they be in an area that inhabits mould. Throat, nose and eye irritation, coughing and wheezing are all common side effects. Prolonged exposure to mould can worsen these symptoms and they often have a worse effect on those that have respiratory issues.

Mould is often easy to spot when it sits on walls and other noticeable areas, however when it is inside a machine or appliance, it can be a lot more difficult to detect. However, if symptoms such as the above are noticed along with a musty smell in the room, this may point to an issue with mould.


Mould can thrive in moist environments, but there shouldn’t be any water residing in your air conditioning unit. If excess water is found inside the unit, this could mean a repair is necessary.

To prevent the build up of mould inside your unit, ensure that it undergoes maintenance as required by the manufacturer. Making sure the unit is free of dirt, dust and debris as this can play a significant role in reducing the opportunity for mould to grow.
