I have installed a Goodman 16 SEE 410a .
Could not get the SH and SC in balance so I adjusted the TXV but could not get below a 45* coil.
I always uses the delta T OF 18* TO 21*.
tECH SUPPORT SAYS i WAS IN IN THE DARK AGES AND SHOULD BE USING a delaT T on a 16 SEER of 15 to 21.
But my SH wa not right and the S and I MANUAL SAID TO ADUST SH TO ACHIEVE the evap temp drop.
Please advise and what is the right method.
Is it 40 or 45*/
