Check the compressor see if there is a fitting with the screw and inside the screw has a pin. If the compressor has this fitting, that for the Freon R-22 charge use. good luck!

I have a GE Air Conditioner - Model #AEW05LBS1 it is about 10 years old, Haven't used it for the last 2 years, but needed it the other day. When I started it up it does not cold, just blows the warm air...


Small units such as yours are disposable, but can be charged through the process tube. Refrigeration systems are sealed units and refrigerant don't just evaporate out in thin air. There must be a leak in the system. After repairing the leak, the system must be evacuated of all air that was pushed into it by atmospheric pressure or it will never work properly. To charge it, you need a piercing type schrader valve and attach it to the process tube (resembles a pig tail at the end of the coil, crimped off).

We have a 4 year old maytag a/c - M1200 16 seer unit. The compressor has stopped running several times durring the hottest time of day - the air handler keeps on running - which brings in warm humid...


It may be overheating, but chances are it has a high limit control switch which may be bad or it is overcharged with freon, in any case the limit and/or the freon charge needs to be verified by a qualified person who know the proper method's for charging and verify charge.
The hotter outside temps cause the high side pressure to rise, with a properly charged system it should operate properly even at 120 degree temps.

The compressor is sweating bad and can't get temp down below 47 .the thermostat is set at 38 degrees and the compressor is charged to 37 degrees which is 34 psi.


Air Conditioner's primarilly use R-22 38 degrees R-22 is equal to 65 PSI

Can you tell me how much freon a Intertherm 3ton split Strait cool Elec heat ( 1998 )Can't read model #


It would be hard to say by just giving you a number in pounds and oz. The condenser is charged with enough freon for up to 25' of line set. Even though it is a 3 ton unit, they all hold different amounts, yours may have a accumalator, a liquid and suction line drier ect. If you are doing the charging your self, when there is no data plate telling the amount the unit holds, we use a pocket pressure/temperature chart. We charge the unit according to the outdoor air temperature, wet bulb, sub-cooling or in your case superheat using your manifold gauges. With the system pulled into a vac, you charge through the low side port if using R-22 watch both your head pressure and low side using the increments and pressure/temp chart that you can pick up for free at any wholesale a/c refrigeration parts house. If I new what the ambient temperature was where you were doing this, I could help you or tell you where your gauges should be, but you really need to check the superheat to make sure you are not over charged which will kill the compressor due to liquid in the compressor. I would have to charge it my self if I did not know the charge which most units will not even show on the data plate.I hope I have been of some help to you.

Carrier 38yca030370,with copeland compressor M#cr28k6-pvf-270, i need to know what refrigerant it uses. thanks


How old of a unit is it? Chances are it is R-22. If it is newer than last year it may be R-410a. The unit should indicate what type, and charge (lbs/oz) on the nameplate of the outdoor condensing unit. Hope this helps.

The unit only blows warm air. it just stopped kicking on the condenser/compressor to make that radiator cold and blow cold air. any help?


The compressor is not starting either because:
1. The compressor has gone bad
2. The system is low or out of refridgerant. There may be a slow leak, when there is no refridgerant in the system the compressor will not start.

Fix:
Re-charge the system with appropriate refridgerant, if the system has a charge already or holds a charge when you charge it then the compressor should start.
If not the compressor could be bad, sometimes you can get a hard start kit instead of replacing compressor. If the system does not hold a charge then you have to find and repair the leak before anything else...

Good luck. Please give good rating, it meens a lot to me....Feel free to contact me again...

Adding freon to my central air


Well duprees, first you got to have the right instrumentation for charge freon to a a/c system, now, the charge line is the thick line, wich it means the suction line, the colder line, or the most robust line on the compressor.
Then, the system uses freon 22, the right charge, with the system on and the compressor running is 68.5 to 70 psi.
This should give to you about 40 degrees(farenheit) at the evaporator, the panel that gets cold in the system.
This pressure should be at the low side, meaning thicker line in the compressor unit.
Hope this help you......



Good luck.......
