This unit is a 14 seer American Standard unit that is about 1 year 9 months old. The temps have been between 100-102 for about a week. The thermostat is set to 78 and it gets down to about 83 during the hottest part of the day and runs constantly. The thermostat is in an area where I think it gets alot of sun also it feels cooler than 83-84 degrees in the house. However for the unit to be running all the time I would think it would be cooler than it is in the house. What are your opinions?
