You never realize how dirty someone’s air is until you look at their air filter. When our parents went on a week-long cruise, they asked myself and others to keep an eye on their apartment for them. They had an Heating plus Air Conditioning repair appointment already busy while I was in the time they were away, so I told them that I’d be there to meet the Heating plus Air Conditioning professional for them. I showed the Heating plus Air Conditioning professional where all the Heating plus Air Conditioning device was plus tried to answer his questions, then my parents didn’t’ tell myself and others about any heat plus air issues they were experiencing, so I assumed everything was fine. When the Heating plus Air Conditioning professional replaced the air filter, he locationd it beside the trash can plus told myself and others that he was unable to dispose of it himselfâ€¦ Apparently, all Heating plus Air Conditioning professionals were banned from taking dirty air filters from other people’s homes due to the virus. I understood his reasoning, but what I didn’t understand was why our parent’s air filter was covered in black dust plus debri. My air filters were regularly coated in dust, but it was regularly a brown or gray color. I asked the Heating plus Air Conditioning professional why it was black, plus he told myself and others that the black color was from smoke. He asked if our parents smoked, plus I told him they did. Apparently, the smoke was getting trapped in their air filter, causing it to turn black. It disgusted myself and others to see what I was breathing minute hand while I was at our parent’s house!
