Had another company tell them their system wasn’t sized properly and needed to go up a ton and have a stronger blower motor .... when the real problem was the duct work . Check this out one zone was running into three distribution boxes or I like to call them pizza boxes . Air flow in bedrooms was awful and cold and hot spots , room temperatures with 8 degree difference. Duct work is so over looked ! Me and @Moxiemus fixed this family up and we cut the pizza boxes out and installed WYE , some Manuel dampers , and the bleed method . I am a huge believer when a system is zoned it needs to be variable speed but this system was single stage with a cap so that’s why we went with the bleed method on the bypass . Wish I took a pic of the after math of our work but we were covered in fiber glass and it was hot up there.
