HVAC filter replacement question

[Matthew King]

I'm new to the whole landlord game and hoping for some clarification.   Do you rely on the tenant to replace the filter or do you do it yourself (monthly), and would that dictate a monthly inspection of the property?  And by inspection, do you actually inspect everything or just kind of say hi/bye and be on your way if nothing looks crazy.

In my lease, the tenant is responsible for the AC filter. However, I really don't expect the tenant to even remember when the filters need to be replaced. Ultimately, I went in there and replaced the filter with the 4" thick one that actually lasts a year. So I only have to do it once a year and I can make sure that my AC is going to be taken care of. Ultimately, the property is mine so I don't want to risk components breaking down and costing a lot more later because I expect the tenant to take care of it. No one will take better care of your property than you.
