High super heat , high sub cool

[Paul4131]

Recently I attended a complaint that only room is getting 26°C only. ThenI checked a Ac Lennox 2Ton R22 SYSTEM FIXED Orfice
Liquid line pressure - 305Psi
Suction line Pressure - 78Psi
Liquid line Temperature - 119°F (Near Condenser)
Suction line Temperature -83°F(Near Condenser)
From Eveprator Air flow Temp -67°F
Return Airflow to Eveprator Temp -79°F
Compressor Ampere little high
Outside Temperature - 108°F

Can anyone tell what is the issue?
.
I Changed orfice piston 059 , I flushed evaporator Unit

I moved your thread to the
( Tech to Tech Chat- Residential )since you stated you're a technician.in your profile.
This is where you should ask your questions.

[VTP99]

System could be working outside of it's design condition.
Did you clean the condenser ?

[Paul4131]

No , I didn't flush condenser

[Paul4131]

But I cleaned condenser unit and changed fan motor

Test for noncondensables.

[ksefan]

Lower indoor blower speed and retest.

[Snapperhead]

Outside Temperature - 108°F

I know what I would do ..... I'd go home and start packing

[Paul4131]

I changed new orginal blower and blower motor

[Paul4131]

How to make noncondensables test?

[Snapperhead]

I changed new orginal blower and blower motor

I think almost all blower motors have 3 speeds ....

[ehsx]

How to make noncondensables test?

Close ll service valve, pumpdown if possible, manually run condenser fan motor till pressure stabilizes, compare saturated temp to ambient. Should match.

[Paul4131]

Ok I will check

[mjohnson2981]

Low charge.

108 outside? 79db inside. Wet bulb id take a guess at 63...

Should be about 1 degree superheated not 30

[Paul4131]

I released gas and vacuuming, recharged gas . Still Ac is working same as before. Could it be due to excessive heat load?

[Paul4131]

And could it be due to scroll compressor failure?

[mjohnson2981]

I wouldn't expect "a little high" amps if it wasn't pumping. If you block off the condenser does the suction climb?

[Bill mcC]

And could it be due to scroll compressor failure?

You have a very high compressor ratio, so the compressor is working well for now. As Ksefan mentioned, you could try lowering the fan speed till you get 18 to 21 degrees difference between supply and return.

Some Rheem Rudd, split air handlers have single-speed blower motors, that burns my biscuits.

Or blower motors with 5 cfm difference between high and low speed.
