Very warm water coming from H/VAC house drain pipe
Neither the heating or air conditioning was on today.
Noticed very warm water constantly coming from H/VAC house drain pipe.
Looked in attic at unit and nothing unusual with unit visually.
What could it be?

We need to know more about your system.
Gas furnace ?
Heat pump ?
Geothermal ?
Were you in heating or cooling mode ?
Do you have a humidifier ?
If the water was warm I'd expect it to be coming from a humidifier.
Some condensing furnaces discharge warm water but it's usually minimal.

You have eyes on the issue, we cant really see what is going on. Your in heat mode, I assume, no location posted, so no condensate, is there water running to a humidifier, is it a GEOthermal unit?

Miss typed, "The heating or air conditioning were not on today."
Just HVAC with gas furnace.
Not on at all today.

Pictures of the drain would help.
are you certain it’s straight air conditioning with a gas furnace?

Where do you see this water?
AC primary drains usually pipe into the plumbing under a bathroom sink. It would be difficult to notice the temperature?
Air conditioner secondary drains usually come out over a window in my area. If the drain comes out of the house closer to ground level I would expect it to be from the water heater.
A pop off valve from the water heater might put out some warmer water.

Yep, checked hot water pressure relief valve...it's leaking.
