Re: Compressor noise after freon added to 'blowing warm' system

Any chance, that at this point adding oil to the compressor (or other place?) might bring this system back to life?

Thanks,
Dave

Re: Compressor noise after freon added to 'blowing warm' system

The second evaporator can be abandoned & disconnected, just remove the T fittings they used to put it in. Plug the lines to it to keep them clean. Valves are a disaster waiting to happen. Find the leaks now, while the system is together. FIX the leaks. Clean the system out & replace the com...

It simply ran out of oil. Several quick fixes over the years on a leaky system. A secondary evaporator loop that is not used. That system holds 78 ounces of refrigerant, and 11 ounces of oil. Some of that oil gets trapped in the rear unit & lines. Running low on refrigerant does not return oil ...

mk378, I'm not well versed in AC so may I ask for clarification? "High side?" I do not understand what you are asking here. "A CCOT system that is undercharged but otherwise in working order will cycle the compressor rapidly." Does this mean low pressure allows/causes rapid compr...

Compressor noise after freon added to 'blowing warm' system

1) Why would adding freon cause a compressor to seize (or partially?)? 2) Since compressor may be toast already, any down side to reclaiming the freon then adding some oil to the system and giving rechareg another try? (Still has original 1999 orifice tube) Recently my AC started blowing less cool a...
