Does your HVAC system need servicing if the low side pressure is 90 and the high side is 150 and the outside temperature is 94 and the inside temperature is 90?
Yes. Was the compressor running? Answer Depends on the refrigerant, but for residential systems they use either R22 or R410A, and those pressures are not right for either system. If the compressor was running, sounds to me like you have bad valves in the compressor and probably need a new compressor (or a new system) ...
Asked in Chevy Impala
Will the 2001 Impala AC recharge if compressor is not running?
It depends. If the system is low on refrigerant then the compressor will not run until there is enough refrigerant to satisfy the low pressure switch. As you add refrigerant the compressor will cycle until enough is in the system to keep the compressor running continuously. A 1lb. can of R-134a costs about $6.00. It's worth a try. Might be enough to keep you running all summer depending on the size of your leak. ...

Asked in Ford Focus
Do you have to have car running when applying freon to ford focus?
Yes, in order for the compressor to take on the new coolant and oil charge the compressor ideally should be running. It is posiible to begin charging the system with freon prior to compressor initiation, however to get an accurate reading of the pressure in the system the compressor should be cycling with differential valve operating properly. If it is clogged or the compressor is not cycling then then low side reading will give an elevated pressure while charging the system. Does...
