The danger of an A/C system with no air filter

I have found that I am possibly one of the most forgetful men on this planet. I don’t know how, or why – but more often than not, I find that I’ll misplace things that I just set down only ten seconds earlier. It’s aggravating to a fault, and I can’t stand that I’m like this! However, I usually can always remember the really important stuff. Unfortunately, my mind doesn’t always consider the right things to be important. Recently, I went through a day without having an air filter in my A/C system. Let me explain why – I woke up that morning, fully intending to go grab a brand new air filter for my A/C system. I had checked the air filter the night before, and it looked absolutely disgusting! So, I took it out of the A/C system and put it by the door as a reminder. Well, let me explain something else – you can’t run the A/C system without the air filter in place. In order for the air conditioning unit to do its job, there has to be plenty of airflow to the coils inside the unit. Those coils help to cool down the air that goes into the house, but air from inside still has to circulate through the machine to be cooled. The point is, that air filter is critical to keep the dirt, dust and other debris out of the A/C unit! Well, I learned that the hard way. I managed to let the A/C unit run all day while I was at work, totally oblivious to the fact that I had nearly destroyed the air conditioning system. Needless to say, my mind quickly learned that leaving the air conditioning unit without an air filter is a big deal.
