When people have AC units installed, they often don’t think about the aftercare. Filters, gas levels and cleans usually don’t appear on their radar until they get on the phone to a technician. As experts in AC installation and servicing, we see time and time again, people not taking ample care of their AC units and are left shocked when we tell them bits and pieces need replacing or cleaning.
One key element of an AC unit is the filter. On ducted air conditioners, it can be noticed as the big rectangle or square grill, and on split systems is housed on the inside of the unit, generally at the top or under the front cover.
Air filters help circulate clean air through your heating and cooling system by trapping dirt, dust, allergens and other pollutants such as pollen and bacteria.
When they are left uncleaned for a prolonged period of time, they start to get clogged and collect moisture, resulting in the growth of mould.
And as you would expect, this mould is then circulated into the air you breathe at home.
These harmful contaminants not only negatively impact your health and comfort, but they also cause your air conditioner to run inefficiently, resulting in expensive energy bills.
This is why it’s so important to clean your air filters regularly to maintain healthy air quality and better energy efficiency.
As a general rule of thumb, you should clean your air filters at the beginning of each season, which is generally every 3 to 4 months.
However, during the peak seasons — summer and winter — it’s recommended to clean them every single month. Although it sounds like overkill, you’d be surprised just how much dirt can build up in a short amount of time, especially with increased usage.
