When it comes to laundry, I like to do it as infrequently as possible.
I will let it pile up until I literally am down to my last set of clean clothes before I do the wash.
I am the same way with my dishes, only when the last bowl and spoon is dirty and I cannot eat any more cereal will I wash the dishes. I put off showering as much as possible, too, but still have to get clean every other day or so just so I don’t reek. I never before thought about having to clean out my air ducts, but to be honest even if I had known I would have blown it off. If I don’t want to clean the dishes that are right in front of me why would I want to crawl inside the ductwork to clear out dust? That said, once I realized the air ducts had been gradually getting dirtier over the last few years I realized I needed to do something about it. Since I am so dirty I know I generate a lot of extra dirt and dust in the air, and that has to collect inside the air ducts and vents. I called around to a few different HVAC companies in town, but none of them are doing duct cleaning at the moment. With this quarantine going on, most HVAC techs are only taking emergency service calls, for the stuff that can’t wait another day. To get a ductwork cleaning, I just have to call back after the lockdown has been lifted.
