Carie? #1 I have posted before from what I read in posting? If you apartment Is 1500 Sq. feet, tomb rule "you need 3 ton".
#2 If you AC unit is drawing only around 15 amps at full load your unit is only 1,1/2 ton "not big enough".
#3 If you unit is freezing out side as some one posted? you have heat pump and it is working in reveres.
#4 If you unit is heat pump and it has booster heaters for winter see that are not ON at same time while is cooling.
#5 If your unit have high back pressure and low discharge pressure it is good possibility that compressor is going bad.
#6 If unit is heat pump you definitely need to check operating pressures looking at unit would not help.
#7 If it is heat pump mechanic must check switching or diverting solenoid's which make change from winter to summer condition.
#8 Last but not least source power and that compressor is running continuously and not shutting down intermittently
I believe you have stated that at one time was working ok Then check # 3,4,5,6,7&8 Tony

You really need to get some training and/or experience before you go spouting off a bunch of BS
There is no such thing as "rule of thumb". 1500 sqft could *NEED* as little as 1 1/2 ton, or as much as 4 ton(or more). Unless you do the calculations, your doing nothing but guessing.
Ummmm......no. I have a customer with a 4 ton heat pump compressor that only draws 13.1 amps(measured), and less than 15 amps total(measured).
Guess again..... overcharge on a piston system will do the same thing.
Not a normal scenerio unless a new thermostat was installed by somebody that doesn't have a clue, or a sequencer went bad
Not necessarily, there could be a lot of other issues that will exhibit simular symptoms
Same as *ANY* other heating/cooling system. If you don't take quantitative measurements, your only guessing.
Not applicable with this problem
That would cause all kinds of other problems.

Oh my... you did it again. Since you're a refrigeration tech, why don't you keep your mouth shut when it comes to residential air conditioning systems??
Replies follow...
She has a 800 sq ft apartment. I know it's hard for you to know this as it's in her FIRST post!! She also has a Goodman 2 ton unit, as this is in her SECOND post!!
Then how can Goodman get by with the following information for a 2-ton unit??
"Compressor RLA 11.5"
Nothing has been said about the unit freezing. Nothing has been said about a heat pump. Even though, by the model number it is a heat pump. But the fact remains that it doesn't even have to bee a heat pump for freezing conditions to show up!!
Wow, now there's an original thought. Why don't you check the model number? It is a heat pump!
Have you saw anything posted on the operating pressures??
Once again, model number says it's a HP! But even if it wasn't a HP, we would still need the operating pressures and temperatures!!
Once again, it's a HP.
Brillant, just brillant!!
I believe that you need training in the HVAC field, if you want to actually post helpful information!

A piston system with a gross overcharge will freeze from the compressor back to the evap, whereas if its running real low on refrigerant, or there is no airflow, it will freeze from the evap to the compressor. It doesn't matter if its A/C or a heat pump, it works the same.

You absolutely right with one difference that some people can do more in half the hour then some in half month and some people have college degree only to qualify to clean toilet Tony

Condenser freezing because of overcharge that would be some a MAGICAL system. So I tout I seen everything I guess not. Tony

At that point its a evaporator. Dont think of HP components as condenser and evaporator. Think of them as indoor and outdoor units.

What??
I have never come across this and have a hard time imagining it. Normally if they're grossly overcharged, they'll be slugging the compressor with liquid refrigerant. That normally happens after a (so-called) service tech charges the unit with too much refrigerant. Then the unit starts making a noise, so they condemn the system.
You get the call and find that the unit is overcharged. Recover the refrigerant and fix the actually problem and then the system normally operates just fine.
So the question is, how can a system be overcharged, yet it freezes??
