(Continuing our diagnostic of this failing A/C unit) — So in this case we have an evaporative coil that is completely plugged up. You can see right inside there it’s just packed with a film of dust and dirt and pet hair, just any kind of thing that’s in our house because this filter was not changed regularly.

So you can see we’re in the process of cleaning it out right now to provide a better cooling capacity on this coil and also more efficiency on the system.

We can also see that because of this coil right here it’s so packed right now that it’s actually causing the system to freeze up, starving it of air because there wasn’t adequate air flow over it, so definitely an issue there.

So we’re going to go ahead and clean it out right now and get this system up and going properly.
