HVAC - Put Your Money Where Your Mouth Is: Part 2

So this is the third day I have worked/ cleaned the A/C system.  Today was the day I worked on inside part of the system.  (Yes, I know I could use technical terms, but no one would know what I was talking about.)  So, let me show you a picture of it.

The unit on the right is pretty new so I didn't have to worry about it.  The one on the left is 22 years old, and the one I needed to work on. 

So the question is, "Did it have some mold?"  Well, just a little bit.

And to answer the question, "Did it have a bit of dust in it?"  Well, yes.  Yes it did.

So I took my shop vacuum and went to town cleaning the vents.  I also knocked some of the mold and dust off the sides.

I also went to town with the Lysol.  I will say this, it couldn't hurt.  I'm not sure how much it helped, but I let loose with the Lysol.

The next part was to take the unit out, and use the coil cleaner on it.  However, it was bolted in there so well, I had no idea how to take it out.  So at this time I left it in.  I figured I would do more damage than good if I tried to take it out.  I'm a bit disappointed in myself, but as I get to know more about HVAC I will feel more confident that I can take the unit apart without damaging it. 

So, I will talk to my instructors about the unit, and hopefully in the future I will be able to take it apart without damaging it.
