Tapped the suction line @ the compressor & the 410

An undersize suction line decreases the capacity, and causes the compressor to work harder and more frequent starts. It may even experience low suction pressure and high superheat.

HFC-134a ? Critical pressure is 588.9 a . With a 93 LL temp and 575 head, I would suspect 1. Air in system or 2. Ref. has gone critical.
With a 110 psig suction/85 deg.F and a LL temp of 93 deg.F/125 psig

It sounds like it leaked again and there's not enough refrigerant in the unit to cool. That's generally is what causes the cooling coils to ice up. Get your serviceman back and see if he can replace the coils. Repairing them is not a good option.

Hello take a evap coil split (return temp vs supply temp) 18*F would be great.If it is lousy the TXV valve is restricting the flow of freon or the filter drier is clogging.Adding freon will overcharge the system and the suction will NOT improve.

System is running a 24°F superheat and a 0°F subcooling at those readings. Saturation temperature is approx. 30°F lower than return air temperature.

Indications are of a low system charge. Ensure all your filters are clean and there are no obstructions that are limited airflow across the evaporator coil. Ensure the coils are clean and not frozen up.

Have it checked out. Looks like a low charge but can't tell without being in front of it. As far as normal ranges, that all depends on many factors. Based upon the info you have supplied, I would guesstimate that the operating pressures would be in the neighborhood of 350/160 to start and get the subcooling and superheat in check.

According to the reading sound like compressor is working fine .There are other issue that contribute to no cooling and the main one is dirty filters so check your filter to see if it's dirty and clean or replaced it .
If filter is fine then you might have dirty evaporator or condenser coil so clean those out too .
Does this unit have 2 compressor and if it does is the 2 compressor running

God day,
Some thoughts.
1. Are the evap fan motors running, and at full speed. That would give you abnormally low suction pressure.
2. Cap tube sized too small. or partial restriction in the dryer cap tube/dryer when brazing in the lines.
3. Low ambient. What's the temp the machine is running in.
4. Over sized compressor.
5. Moisture. God, 134A is touchy on that one.
6. Was original cap tube soldered to the suction line to create a heat exchanger. Needed on many apps. Definately would cause flash back on start up.
7. Superheat a little low, should be 12 to 15 degrees.

Sorry to sat but the tech has no idea what he is doing. The metering device is in the discharge valve, making that line a low pressure, not high. If the "suction" line is hotthen it is running in heat mode.

check the true psi with the line psi to see if same if psi is good in cooling 225 hi and 70 low on 80'day then compressor is fine and i would start checking for temp difference on the reversing valve sometimes this will cause high suction or high discharge psi shift it manually with by energising it be cooling or heating then pull wire and see how it shifts if shifts good then txv on out door unit could be bad what is the psi in heating on the discharge line going to the indoor unit? most prv's are set at about 350 psi r22 as for suction line size its only hot gas in hp mode os no problem their shows in cooling mode as low suction psi ..hope this helps some also make sure indoor coil is clean!....thanks & rate me

Your suction pressure is erratic, your max. pressure is to much high. You did not measure your unit current reading liquid line press. to complete the data. But the problem of your unit is not the compressor its the system. Try to reprocess the system flush the unit with nitrogen, isolate the capillary tube and flush it with nitrogen to insure that no restriction.
