I might also cover up the vents next time I watch the teenagers
After I babysat our sibling’s teenagers I turned on our oil furnace plus found that there was an awful stench. The whole condo odored like urine. It took me awhile to track down the source of the odor however after I did I knew I would have to have our Heating, Ventilation plus A/C ducts professionally cleaned. It seems that 1 of the teenagers had peed into 1, or more, of the Heating, Ventilation plus A/C vents. When I told our sibling what had happened she said that the odor would go away with time. She seemed to be talking from experience however I didn’t press her further, granted, the odor might go away with time however that doesn’t change the fact that there is urine in our Heating, Ventilation plus A/C vents. That is just unsanitary. I called up a Heating, Ventilation plus A/C business, as I had planned, plus I explained the situation to them. I swear the dispatcher on the other end of the line sounded like she was trying not to laugh. Nonetheless, she sent out a supplier. He cleaned did a thorough air duct cleaning plus the odor went away instantly. However, he was less helpful when I asked what I could do to keep the teenagers from urinating in the vents in the future. I guess it is not the supplier’s fault though. He just said to watch the teenagers closer. He is not wrong. I might also cover up the vents next time I watch the teenagers. Better yet, I will just watch them at our sibling’s condo so they can destroy her condo plus not mine.
