How often should I service my air conditioning unit?

In a normal domestic environment you should be cleaning your filters once a season, however should you be exposed to more dusty or polluted environments it should be done more frequently.  In commercial applications the filters should be cleaned monthly.

It is a good idea to have a professional service once a year – in the same way you would service your car once a year.  A professional service once a year will keep your system working at peak efficiency and reduce the likelihood of any downtime on your system.
