While considering replacing my old system with a bad evaporative coil, I want to make sure that if we get this new system we don't continue to have the same problem spots in the home that we had before. My master bedroom is always colder in the winter and warmer in the summer than the other rooms in the house. We have found that simply leaving the door open to our room fixes this problem but we are not willing to leave our door open all the time.
We have been told 2 solutions:
1) The room needs a return and this will help with the pressure in the room and it should properly heat and cool.
2) Our Allstyle Box coil has one duct that is straight off of it that takes the majority of the heating/cooling which causes our master to not get sufficient cooling. Replacing the Allstyle will immediately help this issue.
Which is the solution that will probably work best?
