The short answer is Yes, the fan is not designed to have a build up of mould settle on it, not only is it extra weight it’s having to hold but it reduces airflow significantly should the build up get too bad, reduced airflow or a total blockage will cause a lack of cooling or no cooling coming out from your unit, eventually running in this state for too long the fan motor will fail.
We have seen the effects of this problem for many years and the key is to keep your units as clean as possible if you want the most out of your units. The other big problem with mould build up and filthy air conditioning units are bad for your health, the air you are breathing in is coming straight out of your unit, when the mould build up is significant, you will start to see little pieces directly below the unit, that’s because there is not enough space on the fan for any more build up so the fan begins spitting it out.
Air conditioning is brilliant as long as you keep your units clean, if you are using your systems every single day and running them for long periods then they are going to get blocked much quicker than someone using maybe once or twice a week, this page has created to better inform our customers so they understand the bad side to air conditioning.
If you require a full deep clean, we can help, the price will depend on your location, and the number of indoor units you would like done, it is best to have a full anti-bacterial clean done along side a full service.
