RE: Incorrect draining, rust and green corroding

most likely would be that when they slid it back into
the housing the tilt of the housing was moved.
this would cause the unit to not drain properly.

re-adjust it so that the water drains where it should
and that should stop the water from pooling
inside the housing.

next time buy a can of coil cleaner and diy it.
most hvac companies don't mess with window
units much. ptacs maybe, but not window
shakers.

best of luck.

Not brass, copper. And copper turns green in the presence of water.

I don't know shops in Phillipines...but hvac supply
auto supply box store like home depot or lowes
would be places to shop.

steel wool to remove rust & maybe water stains
on copper.

no diagram I can find..how is unit installed.
some are as simple as adjusting brackets
that hold it into the window. otherwise
you may have to put a shim of some
type under the front of the unit so that
the rear of the unit is lower.

you'd want the front of the unit about
a half inch higher than the rear.

as long as the unit works..& blows cold
air...you'll be able to sell it.

best of luck.

"copper turns green in the presence of water."

Only if the water has particular other chemical in it.

Chloride is a common one.

stuff grows in standing water.
if the unit is stitting in a pool of water
it isn't unusual for this to happen.

you need to get the unit to draining.
buy a screwdriver with changeable
heads, then you'll have the right size
for just about everything.

best of luck.

RE: Incorrect draining, rust and green corroding

Window units normally tilt outwards and to one side slightly so water goes to the drain hole in one corner.

It also often collects in a small well where a fan dis into the water and sprays it on the outside coil to improve efficiency.

Find the installation instructions.

They should have leveling instructions, often near the end of the installation section.
Numbers like 1/8 inch outwards and 1/8 inch to one side are not uncommon (probably in metric there, 1/8 inch = about 3 mm).

The slime is probably algae.

The unit or the housing should slope downwards.

A static electricity shock (usually once and over) or a continuous shock as long as you touch?

A continuous shock can still be generated by different material rubbing together (like a plastic rotor against a seal) but a fault with the AC power to the unit is probably more common and a serious safety hazard.

Did any wires get pinched when assembling the unit?

RE: Incorrect draining, rust and green corroding

My understanding is that typical, modern window units are supposed to have water accumulating. It gets slung onto the hot condenser coil to help increase efficiency. Sometimes there is a plug that can be removed if this is not desired.

I am going to leave my personal value opinions out of it, but the fact is, this kind of equipment is not designed to be serviced or repaired. You are never supposed to be looking at those green tubes. AC service companies probably have little or no experience in working on them.

"AC service companies probably have little or no experience in working on them."

They rarely have the correct ports for checking pressures or servicing the refrigerant loop.

The fill pipe is simply folded over and crimped closed.

There is not a lot you can do to them besides clean them out if they get slime (algae) growing in the water and change the intake filter.

When they stop working for anything but the thermostat failing they are scrap.

The only thing you can likely do is pull it apart again and look for pinched or damaged wires.

You could use a multimeter to get an idea of the voltage present, and maybe the current.

shopping list grows...
multimeter & screwdriver with
changeable tips!!

The appliance service where I worked 30+ years ago routinely serviced window units ... replacing compressors, repairing refrigerant leaks, even an occasional condensor coil replacement. Of course, that was 30 years ago ...

RE: Incorrect draining, rust and green corroding

I greatly fear giving any advice about using a multimeter to someone as inexperienced as you.
Once you put a lead on a voltage, that same voltage is present on the other lead (on most meter settings, on some of them the meter is just destroyed).

This is NOT a good time to be learning even simple electricity..

LOL!
I had to practice restraint on this thread.
he wasn't getting competent advice??wth??

but it was when he posted that it shocked
when he touched the screw...
we have a family joke that the response
would be to a statement like that...
don't touch it!!

I didn't realize the edit feature worked for
older posts. I'll have to check it out.

hope he got his stuff straight!

energy_rater_la,

I notice MidMike is located in the Philippines.

Maybe he called Technical Support for help and found it had been outsourced to Louisiana - we know nobody can understand those folks.
