HVAC with 2 condensation drains

My images were poor, sorry. But I had a split unit with 2 condensation drains, one high and one low. It “seamed” like there were 2 units, one on top of the other. Is this normal?

High efficiency furnace with AC evaporator at the top perhaps.

Dale. With the model number please describe the HVAC unit.
Can a plenum or cabinet have 2 drains, Yes.

model gmh9511dxad. I can not find anything on this??

So a high efficiency heater will have a condensation drain and then another for the AC (above)?

Yes that is correct!

Great, thank you all!!

You can have as many as four drains on one unit.

If they are not leaking, there should be no issue to address.
