Looking for some adivce on what size trunks to run and when to reduce.
I am looking to frame in a wall that will house the trunks so I need to know the sizes prior to framing.
I am not ready to purchase the acutal hvac unit at this time and will leave this area open.
Questions:
Do I need additional supply reigsters for the bedrooms?
How many returns? ( I was thinking 1 large hallway return)
FYI becasue the floor was finished by previuos owner I could only run 6inch flex duct for all my supply branches under the floor. Ceiling is not an option for running ducts because of rafters and flat roof.
Totatl space is apprx 800sf. This is the second floor of a 1500sf house (total will be 2300sf)
First floor has hvac from oil burning f.h.a. Essentialy I am creating a second zone on second floor.
Attachments show cfm per room as well as distances.
Yes this will all be inspected. Not looking to cut any corners.
Any advice would be appreciated.
Break down
Bedroom #3 228cfm
Laundry room 64cfm
hallway 120 cfm
bathroom 70cfm
bedroom#4 168 cfm
Thank You!
