Arranging for furnace filter changes

[Paul S.]

Hi everyone.

A tenant keeps the furnace fan on 24/7. So the filter gets dirty quickly. I asked her to change it every 2 months and send me a photo of the change-out. She was fine with it. Then one day she got in a bad mood over an unrelated landlord-tenant issue, and said she can change the filter but no longer wants to send photos of the change-outs. Now I don't know if or when the filter gets changed.

Going there myself every 2 months is possible, but is probably undesirable for her and I. (I go every 6 months for routine inspections.)

Any advice on this situation?

How about asking her to simply text me a confirmation when furnace filters are changed?

Thank you in advance!

Paul
