I was getting ready to tell my fiance that it was time to change the air filters in the furnace when I remembered the people I was with and I had the Heating, Ventilation, plus A/C maintenance tech out just more than one 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 Heating, Ventilation, plus A/C maintenance notes plus there wasn’t anything written in there. Had he changed the air filter, he entirely would have taken a single out of the case of air filters the people I was with and I kept in the basement. Then again, he may have had air filters on the van plus it included it in the kit he brought with him when he did the servicing. I hesitated on calling my fiance plus 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 plus I didn’t remind my fiance, he would be sad with me for not reminding him. I was in a quandary over what I should do. I went downstairs plus counted the air filters left in the box. Going by the sold on this date on the box, I knew the people I was with and I should have multiple left if the Heating, Ventilation, plus A/C tech had used a single. I decided to wait another week, 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 more than one weeks since the inspection plus maintenance had been done.
