Out to look at units. Uneven airflow. Some areas are hot, others warm, others cold. Cold areas are using space heaters, so much so they are tripping breakers. Package units roof are from 2014 Found 8 package units on roof. Found 3 mini split on roof, 5 exhaust fans. See video and map. Found 1 tstat not working blank screen. All the units are set to auto and a temp. I recommend switching to either heat or cool. Start small. Today went thru systems found 8 package units on the roof, labeled them on map. Also found locations for 8 thermostats labeled on map as well red dots. They also have 5 exhaust fans. And 3 mini splits. Uneven airflow recommend switching from auto to heat or cool. To see if that regulates temp better. If problem consists will have to get access to duct work. To see what’s going on.
