For most people, calling air conditioning a “lifesaver” is a figure of speech. For other groups of people, though, air conditioning can literally save their lives during extreme heatwaves. Whether that’s true for you or not, none of us should take our air conditioning system for granted.
A basic – but effective – way to keep your air conditioner in good working condition is simply keeping the filter clean. For external units, there may be leaves or twigs that fall from nearby trees that can easily cause trouble. For window units, dust and dirt that has collected over some time can lead to poor airflow, causing overheating or other issues. If you don’t expect to use the air conditioner for some time, it may be a good idea to cover it.
While air conditioners are typically pretty noisy, there shouldn’t be any loud rattling or other strange sounds coming from the unit. If that happens, it may be a good idea to seek professional help!
