Did the Heating, Ventilation & A/C tech change the air filters?

I was getting ready to tell our partner that it was time to change the air filters in the furnace when I remembered both of us had the Heating, Ventilation & A/C repair tech out just multiple weeks earlier.

I could not, for the life of me remember if she had changed the air filters when she did the maintenance? I looked at her post Heating, Ventilation & A/C repair notes & there wasn’t anything written in there.

Had she changed the air filter, she legitimately would have taken a single out of the case of air filters both of us kept in the basement. Then again, she may have had air filters on the van & it included it in the kit she brought with him when she did the servicing. I hesitated on calling our partner & telling him it was time to change the air filter. If it had been done she would ask me if I had Alzheimer’s. If it hadn’t been done & I didn’t remind our partner, she would be anxious with me for not reminding him. I was in a quandary over what I should do. I went downstairs & counted the air filters left in the box. Going by the sold on this date on the box, I knew both of us should have multiple left if the Heating, Ventilation & A/C tech had used a single. I decided to wait another month, knowing that a single month would not make that much difference. The worst that could happen would be that the air filter would be a lot dirtier than usual. Then again, maybe I should just have him change it again since it had been multiple weeks since the inspection & maintenance had been done.
