My father informed me that he wanted me to begin replacing the air filters.
I was unaware of where the air filters were located, let alone how to replace them.
I was outside observing the air conditioning unit when Grandpa emerged from his residence. In addition to living next door, he was always puttering around in the garden while Grandma knitted. She knitted hats, gloves, jackets, and slippers for those in need, and she distributed them. She was a wonderful person, but she despised being in the sun. She stated that she was allergic to it, and my grandfather noticed that I was staring at the air conditioning unit and asked if I had discovered anything interesting. I told him that my father had instructed me to change the air filter, although I was unaware of how to do so. He indicated the location of the air filter’s access panel. We entered the garage, and he indicated the box containing the air conditioning component air filters. After I received the air filter, he instructed me to install it in the same manner as the previous one. He indicated arrows that indicated the top as well as the side that goes in first. When we were finished with the air conditioner, he led me to the basement and demonstrated how to replace the air filter in the boiler. I was elated because I had a grandfather who was willing to assist a person who lacked HVAC air filter knowledge. When my father arrived home from work, I would have been still laying by the air conditioning unit and staring at it.
