The best suggestion I have is for you to find a HVAC company that knows what they are actually doing. Whenever they start to close registers it is an indication that the system was not designed properly to start with.

They should have done a manual D and a Manual J on the home before they could quote you a price since those measurements dictate the actual size of the equipment (heat loss and heat gain) and the exact duct sizes and air flow requirements for every space in your home. Without this being done there is NO help available since I do not like to guess as they have done. All guessing does is create problems like you are having now.

Sorry but I always like to put the truth out there so you know exactly where you stand.
