A very old air filter

Once a house is foreclosed on, it becomes property of the bank which will generally leave the house – ductwork, infrastructure and all – in whatever condition the prior owners left it in until they find a buyer willing to fit the bill. It’s no secret that people who are foreclosed on are often leave the residence in terrible shape. Without the lingering threat of a deposit like in long-term rentals, owners that get foreclosed on really have no incentive to leave the place in top condition. The house on the foot of the hill, however, was mysteriously left looking pretty good. As the real estate agent looked it through, it appeared as though all the belongings were removed and the walls and appliances weren’t even that dirty. However, beneath the surface, in the ductwork in the walls, left a lesson for all real estate agents down the road. It wasn’t until she showed the house to a family that had young boys with rather severe allergies relating to indoor air quality. As soon as they entered, one boy began leaking at the nose, and the other itching at the throat. The family suggested it was the indoor air quality at this residence. Although skeptical, the real estate agent decided to open up the door to the A/C unit and, in the spirit of full disclosure, show the family the HVAC unit contained therein. The mother of the boys suggested to make a quick cut in the duct sealing and take a look in the air duct for a clue as to what might be causing the boys’ sudden onset of symptoms. The real estate agent complied and as soon as he sliced the air duct sealing – POOF! A cloud of black soot emerged from the ductwork. Fair enough.
