Client called us out today to look at airflow issues for one side of the home. Master bedroom is getting a majority of airflow and backside of home with three guest rooms is getting very little. After inspection found there is no proper Plenum to distribute airflow due to original house build. Looking at the possibility of adding a zoning system. If zoning system is not possible, dampeners would need to be added. We will reach out to client when a solution can be determined.
