Upon arrival tech was informed master bedroom still felt colder then rest of house. Tech began investigating air flow issue and found one of the guest bedrooms branch line was disconnected from the trunk line. Both guest rooms are fairly small but have 8” lines feeding them. Tech reattached branch line and closed off both rooms 3/4 of the way. Tech also adjust 8” line that feeds dinning room. Informed homeowner to give it a few days and see how it feels. May need to return with flow hood to accurately measure air flow adjust accordingly.
