Nothing irritates myself and others more than when our crucial sister thinks she’s right, when I apparently believe that she’s wrong, however just because she’s older than me, she’s always assumed that she’s more knowledgeable and wise, but i’ll admit that she’s right a lot of the time, but not in all situations, but for instance, she came over to our house the other weekend and while she was going to see, she saw our husband replacing our air filter, however she made a comment about how it was time for the annual air filter replacement; At first, I laughed because I thought she was joking, however, then, I realized that she was serious; When I asked our sister how multiple times per year she swings her own air filter, she said, “one.” I was in shock! My sister was always complaining about her AC not running efficiently, even though she always made it sound like she was doing everything she could to maintain the AC system.
When she said that she was only replacing her air filter once per year, I immediately understood why her AC plan wasn’t laboring efficiently.
I told her that air filters needed to be replaced at least twice per year, but occasionally more depending on the Heating and A/C unit and home. If you didn’t replace the filter enough, the dust and debri would congest the system, causing the air to flow unevenly and harder, thus causing a higher utility bill, my sister became easily defensive and said that she only needed to replace her air filter once per year, because it was a scam to suppose otherwise. According to her, Heating and A/C companies only tell you that you should replace them more just so you’ll buy more air filters. We’ll see who’s right in the long run.
