Forgive me, I may be one of the moderators but I am not physic nor am I some omnipresence being.

If the OP expects everyone else to know everything in the world then I think he is expecting too much, as are you. :(

Brian !!! What were you thinking to ask a question instead of just guessing like most of the " experts " out there. Let's give moideen benefit of the doubt and hope he's just having a bad day. It doesn't take any knowledge to answer a question. It DOES take knowledge to ask one !! Have a great day and thanks for all your past help !!

If this is r-22 unit the suction temperature is not same for corresponding pressure, check subcooling, superheat and design load

The condenser airflow seems sufficient, yet the cond TD and approach are high, as if the heat is not transferring from the refrigerant to the air.

Sometimes, in areas where there is high automotive traffic, an insulative carbon coating can form on the condenser surface, which interferes with heat transfer. When this happens, the condenser needs to be acid cleaned.
