My uncle happens to be a real germ-a-phobe. Everything has to be disinfected all of the time… He is one of those people who carries around hand sanitizer & uses it several times in a single hour. His whole dwelling is entirely white. The walls are white, the counters are white, the cabinets are white, the bedding is white, & even the carpeting is entirely white. I know this is so he can see any dirt that may be in the dwelling. I also know it is because he wishes to be able to bleach everything in the dwelling. His home smells something like a hospital because he is regularly cleaning it, but you can’t help but notice. However, something I only recently noticed is the fact that my uncle doesn’t have any Heating & A/C appliance vents. I had recently noticed how dusty my Heating & A/C vents were & I realized it was time to call & have my ductwork cleaned. Then I started wondering about my uncle’s ductwork & if he gets his cleaned often. The next time I went to his dwelling I noticed there were no vents in the least. When I asked how he keeps his dwelling so comfortable without Heating & A/C vents he explained that he has underfloor heating & cooling. Of course he brought up the fact that it is basically impossible to keep forced air heating & cooling ductwork easily clean. He didn’t say it in a rude manner although I understood what he meant. He also said that forced air systems easily spread germs all over the dwelling. I could argue about air filters with high MERV ratings & getting your ductwork cleaned regularly even though I knew that wouldn’t be enough for my uncle. Besides, he already had his heating & cooling appliance all figured out.
