I've been working on a Trane Split system with Two Air Handlers and a single compressor condensing unit. This is a single stage system (both evap coils are active at the same time). The TXVs are new. Also no pressure drop across the liquid line filter. The problem I am having is that the suction pressure stays down around 53psig. The coils are not freezing, but I am concerned that there is still something wrong and this is a high priority client. Here are the stats last time it was running.
Indoor Wetbulb 56
Outdoor Temp 80
Suction 53psig
Head 215psig
S/A 43
R/A 68
I haven't ruled out airflow issues but filters and grills are clean, though the duct design is a little wacky. Any ideas appreciated. Thanks.
