So perhaps the air duct in our house was never cleaned. And I’m really, genuinely hoping that this is the case. My pal and I recently had the Heating plus A/C professionals come out to do air duct cleaning plus air duct resealing. The Heating plus A/C professionals who were in my house were exceptional. All the Heating plus A/C dealers were genuinely careful inside my home. I keep a neat plus clean house so I genuinely am appreciative of folks who respect that effort by being tidy. But the guys from the local Heating plus A/C contractor were on a whole other level. Their boots were covered every time they came in the house. And they were so careful to get any debris that got shook loose from the air ducts plus ended up on the carpet, but one of the Heating plus A/C dealers was on it the second it hit earth with a stick vacuum. But the sheer volume of dust plus crud that came out of our air duct was staggering. Apparently, the house was built in a time where they put some serious metals into air duct. While the air duct was horribly filthy. And that makes me gag to guess about. The air duct is in tip top shape otherwise. Still, it was shocking the amount of debris that kept coming out of the air ducts. I was almost embarrassed. In fact, I asked if any of them had seen any residential Heating plus A/C air ducts that were this bad. To my utter shock, they said that indeed, they’d seen much worse. I can’t even fathom what that has to look like. Perhaps these awesome Heating plus A/C professionals were simply being nice to an outdated lady. But wow, I’m still repulsed just thinking about breathing the air that was sharing the air ducts with that grime plus dust.
