First off, hi all. I got a 3ton h/p, change out with air handler and new lineset. I weighed the charge in according to nameplate and added extra for lineset, 11.85 lbs. On starting up the head was 145# and suct was 35#. 75 outdoor temp and 72 inside. Problem is when I checked sh it was high, around 30-35. So I started to add freon to lower it. Suction pressure started rising but instead of the suct temp dropping like it should to bring sh down the temp started rising! Any ideas would be great.
