Honeywell a/c air handler question

I have a Honeywell in the crawlspace.
The pan on the bottom of the green thing has rusted and I'm being told unit is too old to find a replacement part (1994 if I recall). I don't have $3K for a new unit!
So I was thinking if I wrapped the leaking air area with heavy duty aluminum foil and then wrapped it all in fireproof metal tape from Harbour Freight Tools, would that be an okay patch for now?
I am literally cooling, in the summer, and heating, in the winter, my crawlspace and the bills will be outrageous.
Thanks in advance and sorry for the silly idea and question, just out of ideas.

The area between the green thing and the silver box is leaking air out where it has the letters D-SC written

Stickers on the unit

I would recommend you start saving for a new system. That A/C coil is old and that pilot type furnace is old too.
Gas furnaces only have a finite life and from the constant heating the metal in the heat exchanger rusts and gets brittle. The heat exchanger in an old furnace needs to be inspected for rust thru and holes.

The A/C coil is sitting on the ground and there is sheet metal connecting it to the furnace.
Sealing it with metal foil tape would be ok. It's only a quick fix.

That unit is at the end of its life. Id guess you’ll be replacing it in the next year or 2. Gas furnaces sitting in a wet crawl space tend to rot out the heat exchanger.
Your fix will work for a short term. But will not work permanently.

Would just jack up unit an inch and slip new drain pant under it.

My 60 year old GE attic unit, galvanized steel frame supporting coil rusted away, Coil is now resting on Styrofoam blocks.

That would likely be poor advice.
Your unit isn’t an old standing pilot furnace sitting in a wet crawl space.

Thanks all. I am being told no new pan can be gotten due to the age of the unit being a 1992 or something like that.

Something I just noticed. Doesn’t look like you’ll have heat when you need it. Gas valve looks to be off.

That was turned back on. Thanks for the heads up though!
