My HVAC started to smell bad because I didn’t change the air filter

It amazes me how many things that I happen to be oblivious to.

I seriously don’t know how I grew up separate from realizing some things.

I don’t think it is because our parents didn’t try to teach myself and others these things. I actually think it is just because I am a poor listener. It is bad, plus I need to change it. I still struggle with it to this day. I have trouble focusing, plus I struggle to really pay attention to anything that doesn’t catch my interest. One of the things that my dad mentioned to myself and others a few years back when I bought our a/c equipment was that I needed to change the air filter in it occasionally… He suggested we go about it several times per year. I don’t recall him saying that which is seriously bad. I noticed that our a/c equipment was starting to put off a powerful stench that I was not alright with, but I had no idea why! Every time that I walked past our a/c equipment, the stench got stronger, so I knew that it was coming from the a/c equipment plus not anywhere else. I asked my dad why our a/c equipment would be putting off such a horrid smell, plus he asked if I had changed the air filter recently. I told him that I had never changed the air filter in our a/c equipment, plus he started laughing at me. He explained to myself and others how to change the air filter plus told myself and others to to make sure to do it every few months or so. He also reminded myself and others that he had already told myself and others that when I bought the A/C equipment. I truly need to learn to listen.
