No, R12 and R22 are not compatible freons. You need to recharge with R22.

    You must have an epa license to buy r-22. There is a r-22a on the market that doesn't require a license. I know the difference between R-12 and R-22 in the boiling point. I was just wondering if r-22a is compatible with r-22.

Can 22 refrigerant be used in refrigeration?


Hi,

I was under the understanding that R22 was for AC units only, R134 is current along with R409 (hotshot), prior to the was R12 dated 1995 and earlier. Due to the expansion properties needed for R22, I would not mix this with any other freon.

What is going on with our Goodman unit?


If your going to pay that much just have them put in a new unit. It is not that much more and you can get free financing. All the repairman can do is guess and keep putting in new parts till it works. Had a new unit put in and it still didn't work found out it was a bad thermostat. But at lest we don't have the repair bills or high electric bill anymore so it paid for its self in saved money.

AIR CONDITIONER IS NOT COOLING, USING GAGUE, FOUND BOTH SUCTION AND DISHCHARGE PRESSURE VERY LOW. IT IS R22 4 TONS AC UNIT, SUCTION 10 PSI, DICHARGE 80 PSI. COMPRESSOR AND FAN RUNNING.


there is probably a leak in the systems somewhere, it needs to be inspected for a leak and charged with R-22 for proper cooling.
There is a stop leak for air conditioning systems available to licensed technicians to buy, might work if the leak is very small.

Mr slim Mitsubishi - how much fill


On the data plate for the outdoor unit it will tell you what type and how much refrigerant you need. If the line set is longer than 25 feet you will likely need a bit more than what it says. A 40 degrees evaporator temperature is ideal, approximately 65 psi for r22

I have a 30 year old Kenmore 17 cu in. refrigerator that recently has started to run almost continuously. It is otherwise in good shape. Room temp. is 68 deg. farenheit, 70% rel. humidity. I have an R-22...


this unit does not take r22. dont put r22 in it , thats for house acs.this unit should take r12 older freon . but id first check the condenser coils, if this unit has any, some models are internal. usually underneath unit or against back wall. if dirty coils that will make ref. run longer. if coils are clean and cooling or frzing in both sides then maybe your thermostat is not sensing the tempreture properly, maybe hard to get part becuz of age. if unit is frzing and cooling good just running too long, i dont think its low on freon,if its low on freon it wouldnt be working at all . hope this helps

What should refrigerant gauges read when charging walk in freezer?


Depends on what kind of refrigerant its works, if is an old unit probably is charged with R12 or R22 newer ones work with R404 ;for R12 presures should be around 20psi on the low side and 160 on the high side ,for R22 about 60 and 250 and for R404 50 and 350 ;you have to look at the condensing unit tag to find out what type of freon its uses ,or look at the expansion valve at the evaporator coil.

I accidently added 12 oz of r410 to a r22 system,


Do a triple evac. Reclaim, flush with r22, reclaim, flush with r22, reclaim, flush with r22, reclaim. install afilter drier. Evac down to at least 200 microns. Recharge. you should be ok.
My concern would be disposing of the old "now blended" refrigerant
