A/C working properly? Cost -> lower temp?

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 apartment.

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 Regrig 22 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)?

Thanks

I think this numbers above are for the heater... Here's the data from the big fan thing outside: Goodman Manufacturing Co. Model No. CPKJ24-1A Operating volts 197-253

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 air.

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 with it.

It's been running non-stop since 12:00 PM, it's 7:46PM, and the temp is still 83 deg, thermostat still at 80 deg. I would not have said "hours" if it wasn't...

I am not a HVAC person, but here are my goodman a/c symtoms, and cure Goodman 2 1/2 ton split systen 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

for 2400sqft with the t-stat set at 76F and outside temps running mid 90s with humidity at 60 - 90%, my electric bill was only $136

Hire a *competent*, licensed, bonded, insured, professionally trained HVAC technician, instead of depending on some flunkie handiman that couldn't make it doing anything else.

Cheapest POS there is

$75 - $150

Second the use of thermometer. It's the best test.

As mentioned above, if working correctly, the output should be about

20F lower than the input (room temp).

Did they fixed it?

What did they say was the problem?

Generally speaking, you can save / spend about 2% for each degree, although that can vary significantly depending on the indoor / outdoor difference and the efficiency of your unit..

- "Most people can be comfortable with a setting of 78-80 degrees Fahrenheit, plus you'll save 7 percent to 10 percent of your cooling costs for each degree above 78."

That seems a bit high vs. other sources I've read, but again, a lot depends on where you live, etc.

When I lived in Charlotte, 76-78 was fine for us during the summer. Now that I'm in RI, 74F is on the warm side.

I'd be curious to hear what someone in Phoenix might find comfortable at this time of the year.

Its only a 2 ton and probably has a 5KW strip in it..... a losing proposition if they are on at the same time

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

104-F.

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

All depends on how many kw of heat strips are firing up along with the A/C...

The power companies website (Progress Energy, NC) says there's a 10% increase in cooling costs per degree above a 78 deg setting.

What specifically do I ask him tomorrow? (Types of HVAC certifications?) He is being sent by the landlord, which I don't pay for.

Well, I thought if I knew the name of a couple certifications I could mention them. Just searched Google - found EPA Section 608 Certification, NEMI - TABB certification, NATE, and HVAC Excellence.
