Aircon units are either not used in winter or used to generate warm air to heat up offices and homes.

We often get asked whether it is bad for your aircon unit to blow warm air all day long.

Whether your unit is blowing hot or cool air for long periods of time, neither will harm your unit, however just as with any appliance that is used regularly, it needs to be serviced and maintained regularly to ensure it continues to work efficiently and effectively.
