I have trouble with my air conditioner, an "Emerson quite cool" since
the time our window was changed and the air condition reinstalled: On
a high humidity or moderately cool day the cooling"fins" (or whatever
you call them) fill up with ice and block the fan from blowing air
through them. Water also drips on the window sill. The air condition
sits strait and is NOT tilted inwards.
What I suspect is that the conduit leading the water from where it condenses to
the outside evaporator is partially blocked. 
Could anybody advise me either how to get to this conduit and clean
it, or how to find a book, website instuction or other information to
tell me how to do this, or how to find a repairman in Baltimore MD
willing and able to do this.

Hello Vaac-ga,

Being that if you try to repair the unit yourself you may void any
warranty you have, I recommend having it repaired.

weeded out through phone calls those that would not work on
residential units.

By supplying these numbers you have fully answered my question, and
thank you, Nenna-Ga. But I will wait a few days before rating it,
since nlp-ga's suggestion, Stuck or "sticking" t-stat, makes a lot of
sense and I will probably change the thermostat before doing anything
else. If this does not work I have thought of another 2 possibilities:
1. Putting a timer in the compressor circuit which will turn off the
compressor but not the fan every say 10 minutes of each hour , and
keeping it on for 50 minutes to give a chance for the built up ice to
melt and drain.
2:Having a dehumidifier run in the bedromm together with the air conditiner.
I am delaying rating for a few days in hope somebody will comment on these
alternatives. Thanks again, nennaga and nlp-ga.

Sounds good!

I left a message on the 3 last phone numbers but nobody called back. I
will nevertheless rate the question.

If you had replaced the window and now this problem is happening, it
suggest that you changed the tilt of the air conditioner.   It should
tilt back a few degrees.  This would let the water drip on the ground
outside.  It other words the front of the air conditioner should be a
littler higher that the back letting the water flow out of the back
and on to the ground.

Freezing evaporator coils are caused by one of 3 things:
-Low refrigerant
-No or low air flow (dirty filter/coils)
-Stuck or "sticking" t-stat

The drain has NOTHING to do with the evaporator freezing up (that would
simply make a mess).

I?m 95% sure it's low on refrigerant and the cause is the people who moved
It.  They jarred the unit witch ruptured a copper line or coil inadvertently.

Regardless you will have to have the unit looked at by a pro.
