You are showing Air Handler on side which should be in Vertical position.
Or did you leave your PC unattended and someone else typed it?
Now you say:
The pic he supplied shows no such thing. It shows a horizontal
furnace, air entering on right, passing through the furnace,
exiting through plenum on the left, which has the AC coils.
Very normal installation. And there is no "evaporator fan".
There is a blower in the furnace section that moves the air
for both heating and cooling. The installation is perfectly
normal, he just needs to seal the air leakage at the condensate
Dear sir You need some education too!!!
I know that many Air Systems are position on side,
but air handler need to be configure for that set up???
If the leak is in Evaporator, but the evaporator supposedly should have
negative pressure air in other words it should be on vacuum when running,
So I can't say that you are right and I can not say that you are wrong.
But your own words There are different types of evaporator coils.
Look at Evaporator enclosure it shows intake and discharged
from same enclosure, perhaps you can tell me how that evaporator
fan is configured with in. I s it fan as fan or is it Squirrel cage.
First off , you need to configure your newsreader to drop sigs that are
placed below a delimiter - that's a space then 2 dashes then another space .
Now , I'll answer your mistakes in order ...
That blower cabinet can be set either way , it's a condensing type exaust
The evap coil is ALWAYS on the output of the furnace , whether vert or
If you're referring to the "AC from roof" , those are refrigerant lines
and are often run side by side . If you're referring to airflow , the ducts
to the outlets are on the left , air from the furnace unit comes in from the
right . There is NO fan in the evap box , air is moved by the fan in the
furnace unit . The air leak in question is around the CLEARLY MARKED
condensation drain line .
As far as education , I spent over 40 years in building trades , and Dad
ran an AC&R business . An observant feller that isn't afraid to show his
ignorance (that means lack of knowledge ...) by asking questions can learn a
lot ... but those who already "know everything" will continue on in their
unknown ignorance until something bite them on the ass . Yours is coming ...
Oh , and here's the link to that furnace's install manual :
Which clearly says this unit can be installed in either orientation .
OMG, a couple of million air handlers were installed wrong!
An air handler is a motor, blower, controls, sheet metal housing. The
work in every plane. They don't care what direction they are in, they
do a simple operation like spinning and moving air. You put them where
they fit best.

As long as that plane is vertical or horizontal it's true. The furnace and
AC aren't going to work if they are on a 45 deg incline, unless it's some
special design I've never seen. You have issues of condensate drainage
from the burner and AC for example.
Appreciate you looking out but as many others have mentioned it's perfectly
normal to have horizontal installations, it's even in the manual. In my case the
furnace is installed horizontally strictly for space reasons.
