For the past 20 years I have been going to see my great aunt in her little retirement home, as she lives in a cute little building with all of her old friends, where she engages in all sorts of fun activities to keep herself cheerful and socially engaged. I know it’s a great situation for her. I love her tiny little area well enough, and it is comfortable to stay with her for short periods of time; actually, the guest room that I usually sleep in isn’t all that comfortable, but the area seems to have high quality indoor air handling equipment, however this tiny back living room feels much warmer and stuffier than the rest. I have mostly gotten used to trying to sleep in hot and stagnant indoor air. I mean, I accepted a long time ago that her apartment had a single horrible living room, and that was my hot and humid option. It wasn’t until a few weeks ago that I found out there was an easy solution to my terrible, tepid evenings, but my great aunt had been talking about her air quality, so I called out to the nearest local heating and cooling specialist to take a look at her central heating and air conditioning plan and inspect the system. The ventilation specialists asked to inspect the ductworks to make sure there were not any blockages contributing to her poor air quality and circulation. I watched as they started carefully inspecting every air vent around the house. When they got to the little spare room in the back, they really shouted out loud. The ductwork was completely blocked with a mound of fur and debris that looked akin to a living creature. My great aunt never had a pet there.
