This situation generally indicates that the duct system is not balanced properly, or there is an issue with the ductwork leading to that portion of the house. Sometimes it is as simple as attaching ductwork that has come loose, and sometimes the duct system installed in the house when it was built was not sized or designed correctly. If this is the case, then duct modifications may be required to achieve proper airflow to the entire house. If this is a problem you experience, we can inspect the duct system, measure the airflow, and offer recommendations to keep you comfortable in all parts of your home.
