My ac condenser does not work


Do you mean the compressor?

Assuming there are no leaks, you could just need a little freon. But, If the fan (on the radiator) is not kicking on then your compressor may not come on either as it needs the fan to run to help keep the compressor cool. Typically it stems from being low on freon though and Autozone sells freon you can self administer but I would advise asking someone familiar with adding freon to help you so that you don't over fill or try to fill it from the wrong port.

Air conditioner blowing hot


The condenser is not where refrigerant is added to

You need special training & equipment to work on A/C

Have a repair shop diagnose the problem

2000 dodge durango, a/c compressor stopped working after freon was added, did I do something wrong?


at a rough guess you add excessive amounts of freon and that caused the compressor to seize up
gas is added using pressure gauges and not by the can
besides that did you use the correct gas as the r134a runs at a much higher pressure and will deliver liquid back to the compressor which is not good for the operation

I added a can of freon to my 2006 impala and the AC will not stay on the light cuts off


Get a freon charger with a guage and make sure the unit is at the right pressure when running. If the unit starts and then stops you usually need to add freon because the compressor is running dry because the charge cant keep up with demand.

Add freon slowly and be sure the ac is on. A small puff....and wait to see if compressor comes on. When it does you can add until the guage reads in range. Try to keep it in the mid to lower end of the range. Believe it or not the fuller units dont run as cool!

Be careful! Adding freon too fast to a compressor can cause "slugging" and can damage the system!

I just put in freon and now it wont give out cool air


Is the compressor engaging and did it engage before adding freon?
What is the pressure on the gauge for the low side? 25psi to 45 psi is normal when the engine is running and the compressor is turning.

If the compressor is not turning the pressure should read 75psi to 100psi, before the compressor starts turning.

Also, the radiator fan should go on when you engage the air conditioning by turning it up to max.

Refrigerant got low and compressor shut off how do you get it to start to run again?


When you add refrigerant to the system the compressor will start to cycle again. The system needs a minimum refrigerant pressure to work so when the pressure falls below that minimum the compressor wont cycle. If your adding freon yourself make sure to have engine running and the ac on max with the fan on max. As your adding freon the compressor will start when the min. pressure is achieved, watch the pressure gage closely so you don't over do it. I hope this helps you.

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.......

UNIT NOT COOLING(IS RUNNING WHEN PLUGGED)


only reason refrigerent may be needed is that there is a leak so adding more will achieve nothing. unlikely to be needed. i assume compressor is running. probable causes of no cooling are compressor fault or a blockage in the pipe sysyem. not diy
