Checkbox to trigger if true or false

Hello, 

I have rule that should trigger a field update, but my rule is only firing off when the checkbox is unchecked. What can I do to ensure that if the box is unchecked and gets checked or if the box is already checked and gets unchecked, it will trigger my field update. 

Here is my formula: 
  
IF( Maintenance__c,FALSE,TRUE)
The above rule only triggers when the box is unchecked

You can use the 
ISCHANGED(Maintenance__c)

function in the formula.
