Indoor coil in wrong place?

In reality, the chances or creating phosegene gas is slim.
Rusting out the HX, high chance.

I've never seen an aluminum heat exchanger rust. Not saying it can't happen,just that I haven't seen it .

It is not installed in accordance with the manufacturer design. They do not want it like that for many reasons. It someone were to die from CO or the home had a fire do to the furnace the MFG would walk away from it. The limits and such must be soaking wet when running in cooling.

Anodized aluminum HXs pit and rust.

Did you ever see an aluminum chimney liner rot out?

Like I said. I've never seen it happen .Not that it can't happen.

It would be possible. But last I knew, R22 had to reach a temp of 500°F in order to begin to decompose into phosgene gas.

And that is why I said "could result" not will.

I saw that.
Wasn't busting on you.
Just wanted to point out that it is a slim possibility.

[I_bend_metal]

You're right.....we do

so what about gas packs on the roof. most designs have the same setup,with the heat exchangers open to the outdoor air?

And if you check the heat exchanger, you see them pitted and rusted out because of it.
