There are several reasons why this occurs, but here are the two most prevalent.
Air not Balanced in System Balance System with Dampers
You may need you air system balanced, meaning adjust the air flow to all of your rooms so they receive the same amount of air. This balancing could also mean making the rooms you use the most the most comfortable. If one room is cooling much faster than others, the air flow to that room can be lowered in order to even things out and send more air to other areas
The best way to balance the air in your home is by having dampers installed on the individual supply runs that come off of the main supply trunk, which is typically located in either the attic or basement. You can identify these by the small metal handles which adjust your dampers and control the amount of air coming through your duct system. Dampening the air flow to the rooms receiving too much air will send more air to the rooms that need it.
No Dampers Installed in Duct System
If your home’s air flow system does not have dampers, or you cannot get to them, then you will have to balance your system at the supply registers. However, if this is the case, we recommend that you invest in a new zoning system that will let you divide your home into multiple cooling areas (and heating areas in the fall and winter). You will still only have one central AC unit, but you will have a series of dampers installed in your duct work that will direct air where it is needed the most. In these zones, you will also have thermostats that will give you better control of the comfort of your home and also reduce your energy costs.
