Having problems with your Air Conditioners ?

No pressure on suction side of condenser

\015 I have 125 psi on the liquid side and 0 on the suction side. 5 Ton Compresser is running fine. Is there a problem in the coil?\015

Answers :

Hi there,
\015\012 there are several factor we can consider of that status of the pressure of your ac.,if this run at normal operation w/sufficient
\015\012cooling effect,and standard operating pressure,then suddenly it drops to that pressure you said,there is leaks,before you recharge,you should find the leak,locate where tube and repair,testing leakage on tube is not easy job,it uses nitrogen gas
\015\012w/ 1000 psig to charge your system and halide leak tester has been used to find exactly where that leaks was in all your system.soap bubble test is a basic test but also helpul.this should be done by certified a/c technician.
\015\012 beside one factor also is lost compression of the compressor,what ever you recharge,it will not work because of worn out of compression ring at piston,this case is seldom but if the service of your compressor is longer to warranty this may happen,or dried out of lubricant inside compressor.
\015\012 better call on your service center to check on this,regards dont forget to ratew me thanks a lot.
Sounds like system is very low on refrigerant charge,let it run and see if it goes into a vaccum.if you had a problem in the coil your liquid line will have higher pressure.

Have Coleman-Evcon heat pump system. Model DRHS0421CB. Condensing unit has intermittent no run condition. I replaced the contactor, as it was a few years old. I eliminated the thermostat from the equation by twisting together the RYO wires at the thermostat sub panel. This makes the air handler run and MOST of the time also makes the condensing unit come on as well. When it does run together, it cools great. Suction and discharge pressures are normal. The float switch is ok and no water prese

This is a weatherking central air conditioner. Had been looked at by another person before me. Wasn't cooling right is all the information I had. When I walked past it one day (this is at a golf course), I noticed the suction line going into the condenser cabinet was iced up. First thing I thought about was maybe it had to much freon in it.

1994 corolla-I charged the air cond., and it was cooling fine. After about a mo., it was not cooling very good. I assumed it had a small leak. I put my guages on it and the low pressure was running 15 to 20. The high side was reading about 150.I put a can of stopleak and detector in it. Then I put a can of freon in it. While I was putting the freon in it the pressure started to drop on both the low side and high side. Now the low side pressure is running about 15 and the high side is running 0.W
