Unbalanced air duct system leaving some rooms too cold

When the Heating plus A/C professional came over she took a lot of measurements

I genuinely cherish when winter comes, i’m able to go outside plus care about the snow plus mountains with a lot of my friends, then when the snow hits plus there’s enough on the mountain to go snowboarding, my friends plus I will pack up plus take a long weekend to go the resort, there are some things that I don’t genuinely care for when winter does roll around. I have a absolutely long driveway so shoveling plus snow plowing are not my favorite things I like to do doing, it is absolutely time-consuming; Also in my home it seems as if there are particular rooms that are colder than others. I have some vents plus one of the vents blows out a lot of heat plus in some other rooms there is absolutely minimal heat blowing out of the vents, however before I wanted to leave my home for a few afternoons I wanted to call my Heating plus A/C system to see exactly what was going on. I told him about how some rooms feel colder than others, but she told me that it sounds like I have a absolutely unbalanced air duct system. When the Heating plus A/C professional came over she took a lot of measurements. She told me she was taking component measurements of supply, return, room-by-room rapidly changing temperatures plus measuring airflow output from each vent, with also checking any leakage from the air ducts. After receiving the data that was needed to determine if there was an unbalance in my ductwork, she found that on the one side of my home near the two coldest rooms, the ductwork was off at least ten degrees!
