    what's the proper way of using dampers?

    I got a new system last fall and some rooms were warm and cold. The installer came back a few more time to correct. First, they moved ducks around and closed half of the ducks with some panels. when it didn't fix but made it worse. I asked them to install dampers. The dampers did fix some but now entire upstairs feels warm and it takes a longer to reach to target temp than before. Some rooms are still warmer than others too.

    Their recommendation saying my unit (for upstairs, 4 ton) may not have enough air flow is to close damper for certain areas entirely I closed damper for the hall (open to downstairs) and one of the bathroom as recommended. There are total of 5 ducks and 3 are fully open and 2 are closed as much as it can be. Now it takes even longer to cool down upstairs. The temp difference from supply to register is about 23-25. Filter is very clean.

    This contractor was telling me they want to move one of the duck to the unit for downstairs when I get the unit replaced. Then it will fix...I am not sure..

    question:

    is it okay to close two dampers ( 2 out of 5) ? or is it right things to do?
    is there a contractor to handle this kind of issue? I got another one came over and they said everything is normal based on the pressure. They just told me to try dampers in different ways. but I feel hot on 76 when my old unit made me feel cold on 76.

    How many times must one fix something before it is fixed?

    A new install and they want you to adjust the dampers?

    Find a different contractor to inspect this entire job.
