Getting Tenants to change A/C filters

[Steve Mandelbaum]

I remind my tenants regularly to change the A/C filters and they simply do not.  When the A/C fails they call up with an attitude and want it fixed immediately.  

In my lease, I have a clause that outlines if the machine breaks due to their neglect, they will have to pay for it.

Has anyone signed up for an Amazon delivery every other month?  I would have to pay for it and manage it, again I wonder if it is worth my time.
