If my AC technician says my unit is rated at 28.9 amps and drawing 24.8 and should draw about half of rated capacity and that compressor needs to be replaced Is this correct?

There are several amperage ratings on AC compressors/motors. Locked Motor Amperage (LRA) is the amperage that the motor is fused for. The load of the motor is expressed in amperage or wattage, which is probably the case here. Low amperage readings on an AC unit being charged by amperage load would indicate low freon. High amperage readings indicate overcharge when charging by the amperage load. AC units are not accurately charged by amperage readings and the efficiency of motors is not expressed in amperage readings.

Will splicing a 3 wire 240 volt compressor with a 4 wire 240 volt male end damage compressor motor?
It could if you don't get the terminals and motor wires on the correct terminals.
How do you check your home ac unit compressor?
First make sure power is off...there is three leads that supply power to compressor...they should be Yellow Black and Red....make a diagram where these leads connect on your unit and then disconnect them...You will need a multi meter to check ohms of resistance...Yellow is usually the common lead...attach one meter lead to it...now touch other meter lead to black lead...should read somewhere between 1 to 4 ohms...now touch the meter lead to the red wire...should read somewhere between 3 to 7 ohms...next read from yellow lead to side of compressor...if you get any reading then compressor is grounded and needs to be replaced...if you get no reading there, reconnect lead and see if compressor will run...if it will not then if could be possible capacitor is bad...on some units they have start assist capacitors this could be bad also..replace these and see if compressor runs...if it will not run it will need to be replaced..if it does run use an amp meter and check load amps of compressor...
1989 XJ6 - Circuit One Failure Replaced fuse fan ac compressor and still get blown fuse wcircuit one failure occurring Anyone know why or how to fix?
fuses blow because their amperage is exceeded. you have a short somewhere, or the coil on the ac compressor is drawing too much current. DO NOT PUT A HIGHER RATED FUSE IN PLACE OF THE OLD ONE!!!!!!!!!!! that will cause more problems (such as a fire) is you have a wiring schematic, you can unplug all items less one, and try that until the fuse blows. you can also try to splice in fuses (of the correct amperage) in various points in the circuit if the wiring is hard to trace.
Why does the air conditioner get cold than hot than cold hot etc every couple of minutes you had it drained vacuumed with new freon Tested for leaks none need help?
We're assuming the compressor is always running (not cycling), during this time that it's getting cool, then warm/ hot? If the compressor cycling during this time (air getting cool, then hot or warm)- you likely need to concentrate on the electrics that make the compressor run (ei, pressure switch, electric clutch, etc.) answer u need a new drier and the correct amount of gas in system checked a drier is not much to buy
What is the unit used t measure the capacity of a dam?
It makes sense to use a unit of volume, such as cubic meter, or liter.
We replaced the ac compressor clutch and need the correct torque for the clutch nut Thank you?
Need more info like year, make and model.
Why is compresser frozen?
When A compressor locks up on a car 99% of the time it is due to the compressor becoming worn out. When a compressor starts to wear small fragments of metal and rubber are pumped through the system. These fragments eventually make their way back into the compressor and jam it up destroying the compressor. This contaminates the entire system usually and will require a qualified, licensed technician to repair correctly. The system will have to be evacuated and all refrigerant recovered. The compressor, accumulator, and orifice will all have to be replaced in order to have a warranty. The entire system will have to be flushed. Next reassemble the system. Then a vacuum must be applied to remove any and all moisture in the system any moisture in the system will freeze and cause poor performance. Then finally the system must be recharged with the correct refrigerant and the exact capacity in weight, too much or too little will again cause poor performance even if its only one or two ounces with some systems.

How do you spell carrying capacity?
That is the correct spelling of the ecosystem term "carrying capacity."
What if you charged the air conditioning on your truck backwards?
As long as the compressor is the correct one for the unit and the compressor was not damaged in the error (as it can if fed liquid refrigerant). No fault will be evident as the compressor can only pump one direction.
