My second floor is hot compared to the first floor.
I’m a new home owner and just closed on a new construction. I have dual zone with two thermostats but the second floor is always way hotter compared to the first floor. I have tried only turning on the second floor thermostat but no changes. The vents upstairs barely have any air coming out but the first floor has plenty of airflow even with the thermostat on the first floor off. I have tried flipping the little switch to summer for a few minutes but there isn’t any difference in airflow. Is there maybe something wrong with the dampers or is the unit just not working properly?
Edit: i believe there is a crawl space in the attic could there be another damper maybe up there that I have to flip open?
