What is the term for the "radiator" in a furnace and how do you replace it?

The thing that looks like a car radiator is attached to the furnace via one main copper line that sends three (all ~3/8") copper lines to the radiator. Also there is another main line (~3/8") that branches out into three skinny copper lines (~1/4") that go way down into a deeper portion of the radiator.

Any ideas how to remove those lines and attach them to a new radiator? They don't appear to be attached via solder.

Thanks

That's the evaporator coil and you cannot remove it until the refrigerant is recovered by a licensed HVAC technician. Unfortunately, that's not a DIY job, call your local HVAC company.

Why do you think that coil needs to be replaced?

I agree with Tom.

It looks like you have a hot water coil above the blower but the coil that you zoomed in on is an evaporator coil and should only be removed by a licensed HVAC contractor.

hmm so now I'm wondering if it's simpler to just replace the entire furnace ... ? DIY-able?

No, the same issue of refrigeration would apply.

Thats an air handler not a furnace, it heats using your water heater, not the best system but better than a grill in the living room in the winter. Why do you think you need to remove the coil?

So after more research, my options are to either pay ~6k for a new R-410 system (the existing one is R-22) or $1k to fix the coil and "refuel" the existing system.
Neither of these are good options for me so I looked into standalone AC units but the condo assoc says no, all windows have to be uniform from the outside.
Any other options (aside from sucking it up)?

Ductless Mini Split . Probably a dual A/C & Heat Pump .

Does the evaporator coil have a leak ?
