Dear my brothers.
I had installed Goodman 3 tons unit, straight cool, 10 K heat kit, R410 A. House about 2000 square foods. The first time unit ran the temperture at the closest of the register was 63 F .I thought the system still has low freion and i added 1 pounds . After that the closest register 70F and the temperture not go down like I set 78 F, indoor temperture 80. Ran 30 minutes temperture still 80 F. Help me Please. Thank you.

Withdraw the refrigerant and weigh in the correct charge then check the usual readings, sub-cool, supeheat, airflows ect.
