Ice keeps forming on the system

My fiance plus I take pride in how wash we keep the inside of our house.  Many people who mop plus vacuum officially plus also have no clutter anywhere in sight will forgo consistent dusting plus will have a visible layer of it all over their windows, counters, surfaces, plus furniture throughout their home.   It will be recognizably visible on black objects care about TV plus laptop screens. In our house, we even keep the surfaces inside dusted at least twice a week. I suppose it’s safe to say that calling our home “spotless” would not be an overstatement at all, it really is that wash inside.  So when we started finding dust all over the home every single morning all of a sudden, we both were sad over what the source could be. The people I was with and I couldn’t imagine what could have changed since our habits were the same plus we were cleaning as officially as we ever had in the past.  The people I was with and I spent more than one seriously stressful weeks speaking to multiple professionals on the cellphone plus using different chemicals to wash throughout the home before we found the source of the problem. Unfortunately, we have our air return for our air conditioner right at floor level on a wall near our front door.  As I was taking out the trash a few days ago, I noticed that a massive chunk of the weather stripping that creates a seal underneath the door every time it is shut was mostly torn off plus barely still attached to the door. This effectively created a massive half inch thick air gap underneath our front door for dirt plus dust to blow in through the night.  When your air return is a few feet away plus drawing in constantly, all of this extra dirt plus dust goes straight into the Heating plus Air Conditioning proposal plus then is sprinkled on every surface as it leaves your air vents. After fixing the weather stripping plus cleaning up around the front door for the last time, it seems as though our home is finally back to normal.
