I was futzing around in the basement last week, & I found 2 boxes of air filters.
One box was furnace air filters, & the other was for the A/C unit. I wondered why we had full boxes of air filters in the basement, so I went upstairs to ask mom. She looked at me love I was crazy & asked if I was sure? I showed his the boxes, & he said they had bought a couple years ago. She now wondered what Mom had been using all this time, when he changed the air filters. When Mom got condo from labor that night, mom said nothing about the air filters, however he was being extra nice to him. After he finished eating, he said he had something to talk to him about. He smiled, & he asked what air filters he had been using in the furnace & A/C unit? He stuttered for a moment & said he used the ones in the basement. He had to update them because they were all out. My eyes must have grown super wide because he sat back down even though he had just stood up. Mom told him he needed to stay sat & asked him when was the last time he had changed an air filter. I almost laughed when he asked his if he thought all he did was nothing. He worked for a living, made sure the lawn got mowed & did all the chores he put on his honey-do list. She told him he needed to show me how to change the air filters. She would not use his currency to maintenance a furnace or A/C because he didn’t suppose decreasing an air filter was important.
