Is it okay now to discuss technical things (rather than just general questions) with property owners In AOP?

The same as when they post in Tech to Tech!

Well, the question is about calculation of Superheat when the suction line temp starts at a given value, then declines appreciably as the system continues to run. In this case ... temp of suction line at 43 at 10 minutes after system start-up, down to 37 an hour into system running.

But, to answer the other issues asked about ....

1. Airflow not a problem. Motor and squirrel cage clean. Filters clean. Blades spin freely. Lots of air moving over the evaporator coils. Although cleaned them in spring, again cleaned evaporator and condenser coils to the point I can eat off them. Its my system. So, I know there's no major recent changes to air flow.

2. Evaporator coils are fixed orifice, piston, capillary .... NOT TXV.

Thank you Kesfan for the chart and info. Did follow through assuming that Superheat of 7 (using the assumption that its calculated based on the initial line temp of 43), was close to the recommended superheat of 8 ( determined based a good wet bulb reading and using charts posted on the system condenser).

Just wondering though if it's normal for Superheat to decline, and appreciably so, as the system runs?

Not asking for advice on repair.

Thanks in advance.

#1 What/s the TESP?

Clean, Good, Not a Problem.......... is NOT good enough!
