Why Return Air Flow Is Important
When installing a new furnace or air conditioner it is very important that you have enough air flow returning back to the furnace. If return ductwork is undersized you will have poor airflow to the farthest rooms. Another sign of undersized ductwork is that you will hear a "banging" noise when blower shuts off on the furnace.
The customer had also complained of poor airflow to bedrooms and a banging noise coming from furnace. In this installation we had to install an upsized return drop ( to the right of the furnace). After our modifications, Our customer noted more airflow immediately in 2 bedrooms.
