Purchased a Honeywell humidifer. Their installation instructions are a
little vague. I have what I htink is a High Boy furnace where there is
a cold air return on the left side of the furnace and above the furnace
is ducting with the AC evap coils and the duct leads up to the warm air
supply ducting for the house.
Do I make the hole and mount the actual humidifier in the cold air
return dicting or on the warm air supply above the furnace? If its the
warm air supply then I have an issue in that the only p;ace I can mount
it is in front of the Evap coil and from what i am told, the humidity
can damage the coil.
Please advise. Any help is appreciated and links or diagrams would be
even better.

thank you!

Your setup is all wrong. Your cold air return should come down on the
right side.......Not the left!
You'll need to reverse the return air duct first.
Then install a ReverseFlow@Ductbooster.
Then and only then can you put the humidifier on the return.
Otherwise, you are stuck with installing it on the supply plenum.
A new thermostat is always a wise install with a new humidifier. Dont
forget the new low voltage wiring.

The Cold Air Return is on the left side if you are facing the front of
the furnace. Are you saying its installed wrong? What is the difference
which side it comes down as long as the air returns to the Furnace and
runs through the filter and is heated before its sent up the warm air
supply?? Its been working fine for more than 10 years now.
