This is a rather unremarkable project, but after spending over $200 on a chemical wash for my A/C unit, following the cost of a thermal sensor replacement due to overheating – some dust mitigation was in order.
In my defense, the HVAC installers got me all paranoid. I’m familiar with washing A/C coils, but with this fancy new unit they impressed upon me the importance of not washing the unit too thoroughly, lest I fuck it up and short out the board. I had just spent $15K on this, so I definitely didn’t want to fuck it up.
Turns out I fucked it up anyway by not washing it enough. I can’t win.
So hoping to strike a balance in the proper washing, I though it might help to simply reduce the amount of airborne dirt in the unit’s vicinity. Also, I didn’t like the accompanying mud pit that appeared with every rain. So I threw down some pebbles.
Not every post here is interesting.
