Atlanta area, 3 zone residence about 1200 sq ft per zone. Before we bought the house the upstairs was remodeled and a couple of flexible ducts were added to the new areas. It appears that this was done pretty much randomly. As a result, we have very un-even heat/cool. That is parts of the house are colder/warmer than others depending on the season of course.
I have had two HVAC guys eyeball the system and both came away with the "you need to replace the entire system" philosophy. Both downstairs units are similar vintage and both operate very well so I am not willing to buy this theory.
Are there sources for "balancing" residential units like this, maybe a more "professional" duct installation at a reasonable cost?
Any ideas would be greatly appreciated.
