In-line booster fan
Our master bedroom was an addition to the second floor of our house by the prior owner.
When they did this, they cut into a trunk that is probably now undersized due to the heat loss of the new room.
If we force the blower of our Carrier variable speed system to HIGH, the room stays in sync with the rest of the house.
Can I put some sort of in-line blower in the trunk to boost the CFMs so that it gives the airflow a boost, regardless of the main blower speed?
The trunk is an 8"x14" rectangle that feeds a 400 sq ft master bedroom (2nd floor, vaulted ceiling, no attic above) and a 180 sq foot first floor room with two exterior walls.
The location were I have access to the trunk is a vertical section with an 20"x14" cross section. I can expand the trunk if need here location to accept a larger fan if it would help.
