Did the HVAC tech change the air filters?

I was getting ready to tell my husband that it was time to change the air filters in the furnace when I remembered we had the HVAC service tech out just two weeks earlier.

I could not, for the life of me remember if he had changed the air filters when he did the maintenance? I looked at his post HVAC service notes and there wasn’t anything written in there.

Had he changed the air filter, he probably would have taken one out of the case of air filters we kept in the basement. Then again, he may have had air filters on the van and it included it in the kit he brought with him when he did the servicing. I hesitated on calling my husband and telling him it was time to change the air filter. If it had been done he would ask me if I had Alzheimer’s. If it hadn’t been done and I didn’t remind my husband, he would be upset with me for not reminding him. I was in a quandary over what I should do. I went downstairs and counted the air filters left in the box. Going by the sold on this date on the box, I knew we should have ten left if the HVAC tech had used one. I decided to wait another month, knowing that one month wouldn’t 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 two weeks since the inspection and maintenance had been done.
