It's 90 deg. outside, humidity is 37%. The A/C is set to 80 deg. The
temp in the apartment is at 83 deg, and hasn't gone below that. The A/
C has been running non-stop for hours. The temp out of the vents is
colder than the air in the apartment, but not a lot colder. (I don't
have a thermometer.)
Maintenance fixed the A/C only a month ago when it completely quit
working. Our electric bill that month was $320 for a 800 sq ft
Maintenance is coming tomorrow. How do I make sure they fix the unit
right, or make the landlord replace it if it won't work properly? The
electric bill is outragous.
The unit doesn't show a manufacturing date, and I can't find the model
no. on the manufacturer's website. Here's what the stickers say:
Goodman Manufacturing Co, 1501 Seamist Dr,
Houston, TX 77008
Model No. AW30-05C
Part No. 20203-23
Design PSIG 150
Heater Amps 208/240V
Motor 1PH 60HZ 3.5 Amps 1/3 HP
Single Circuit 17.3/20.0
Min Circuit Ampicity 26/29
Max Overcurrent Protection 30/30
UL Listed - G0587770080
Also, once the unit works properly, how much more does it cost to keep
the apartment at 76 as opposed to 80 (above conditions)?

That is a 2-Ton condenser for a mere 800-sq.ft. in a dry climate, it
should handle that heatload with ease!
If the interior of your home has a low humidity, a mere 90-F outdoors is
not a heavy load on that system - when it is operating properly.
A room temperature of 76-F should not be difficult to achieve with a
very moderate electric usage.
I cool over 800-Sq.Ft in an old 1930's home with a lot of windows with a
mere Half-Ton window unit. Your unit is rated at 4 Times the BTUH and
mine will pull the temperature down to 76-F with outdoor Heat Index at
Check my pages & use a thermometer to get all the needed readings.
Post the data. There may be some useful clues in that test data.
Do the outdoor condenser Temp-Split, it can also be helpful. - udarrell

You really need a thermometer. The output of a properly-functioning A/C
should be in the neighborhood of 20 degrees less than the room's ambient
Cost varies dramatically depending on your location and the cost per KWH.
For example, I'm in Houston (same latitude as Cairo) and my electric bill
(for 1500 sq ft), keeping a temp of 72 degrees, was less than yours.
Running for hours could mean anything more than one hour. There's not
much information there. Let it run overnight. If it can't bring the apartment
down to temperature overnight, then there's something definitely wrong

Outside kept running. inside, airhandler fan, wasn't running.
Opening side of airhandler, you could see the coil was frozen, It also
froze part of the condensor coil, outside.
It would be ok for a few days, then freexe up.
The problem was the fan relay, which turns the fan on. It's located in
the airhandler, with the other wiring.
Good luck with it. Someone here might know the problem

Don't be snotty, especially when you're asking for free advice.
Is there any chance the fan is on ON, and the thermostat is not
accurate? Turn the thermostat down to 70 and see if goes lower than
it is now.
Also check the outside unit and see if it is making noise, and see if
you can tell if the noise is the fan and the compressor, or just the

Gee, do you really think there's something wrong if it can't get down
to 80 deg overnight??? (It would do that with open windows and no A/
C.) I think I was more than polite.
The fan is on "Auto," so as to not recirculate air through vents in a
hot attic when the compressor isn't on.

Your original post was unclear as to exactly how many "hours" it had
been running 2? 3? 6?
Trying to determine AC performance without thermometer is futile
Oh & for clarity don't use 12:00PM ....use noon or midnight to avoid
Clearly your AC unit is not working....for a 800 sq ft apt get a
window unit. It's in your interest to reduce the operating costs you
can easily save the cost of the unit in a few months.

reading the thread before all the important facts were in.
And did you say that you had ever used AC before?
And again, you hadn't said how many hours. We can't read your mind.
What you think that any buman (who has ever used AC) would recognize
might well not be what someone else thinks.
You were no way "more than polite". I think you were less than polite.
You told him how many hours and then said "I would not have said
"hours" if it wasn't..." as though he is supposed to know you
personally and know you how reliably you report the facts. As if he
had insulted you and you had to make it clear that you didn't deserve
the insult. I woudn't have given the reply he did , but he didn't
insult you. He explained why "hours" wasn't enough, and then he made
a suggestion, to run it overnight, I presume because you first posted
at 7:24PM Eastern Time.
And even if you are 100% reliable, you still don't get it that
different people have different ideas of what is enough time for
things to cool down. It's inevitable that at least a few of them will
think that too little time is enough. How do we know you're not in
Most people, when they said hours and the other person said, in
whatever words, How many hours?, would just have replied, "Sorry.
Good to know.
The reason is fine, but even someone who intends to keep his fan on
Auto, for whatever reason, might accidentally knock it to ON. Or he
might put it to ON for testing and forget that he did so. Just
yesterday someone posted about flipping a switch and not remembering a
that he did. That's why it's important to check.
