I noticed that the airflow from the air conditioner was kind of low last night.

This morning I opened up the system and found the filter nearly clogged with soot. I took the filter outside and washed it clean. Here is the residue of some of what was on the filter.

Nasty huh?

My helpful hint to you is to check your air filter and clean it before we reach the height of the summer and you really need the air conditioning.
