Hello,
I am new to this, and am doing it myself so..! LOL I have 3 questions about my Ductwork, and there is a "layout", if you will, of the duct work description at the end of this!
First of all, I know my A/C or central unit is brand new and is working, but I think the duct work may/is laid out wrong.
I have sealed/caulked and insulated all of the ducts, (2) Y's and the plenum.
But, my daughter's room which is in the front of the house (North West side) is not getting enough cool air so I know it will be cold in there this winter. I have had to cover the West facing window in her room with foil just to try and help with the heat in the afternoons.
I have tried adjusting the air flow to all the vents but it is not helping.
The Front room measures (13' 6" X 8' 6"). There is a 6-inch duct to vent in the center of her room and is Y's off of an 8-inch duct (round). The other end of the Y is over my bed and is a 6-inch duct (My room is 17' 7" X 13' 11").
There are 7 other ducts in the house (full description is at the end of this message).
The two in the living room which runs parallel to the line that goes into the bedrooms. (To the East) An 8-inch duct that Y's off into 2 6-inch ducts.
The other 5 of them are 6-inch ducts that are direct from the plenum.
2 of the 5 are almost directly over the return to the unit. (Bad design I know!)
This is a rent house so I will not be "moving" the vents. But I was wondering:
1.) Should the duct work should be a different size?
2.) Should it be attached to the plenum differently? (I.E. should the 8 inch line not Y off into the Master, and just go down into a 6-inch directly to the Front bedroom)
3.) If the above question is correct will it be ok to Y off the 6-inch duct that goes into the back end of the Master Bedroom (closested to the plenum), and attach the 6-inch over my bed (which is roughly 15 feet from the plenum)?
3.) Should the 2 vents over the returns be 4-inch not 6? Would it really make that much differents?
The house is roughly 1500 square feet. And runs North to South, with the front door in the North End.
So the layout is (ruff measurements here! LOL):
1.) Front Bedroom (13' 11" X 8' 6") is on the North end 1 6-inch duct to vent, it is roughly 20 feet to the Y.
2.) Master Bedroom (17' 7" X 13' 11") South Western Side of the house 1 6-inch duct to vent on the North end, which Y's off from an 8-inch duct to the front Bedroom. It is roughly 15 feet to the plenum.
There is also 1 6-inch duct to vent that runs directly from the plenum about 5 feet into the South end of the Master front the door to the bedroom. The unit, and first return is located directly outside the Master Bedroom Door.
3.) Master Bath (7' 6" X 7' 6") is on the South Western side of the house. There is a 6-inch duct to vent directly from the plenum.
4.) Living room (21' 4" X 13' 7") is on the North Eastern side of the house and has two vents. The line to the living room runs parallel to the line that goes into the bedrooms. It is a direct line from the plenum and is an 8-inch duct that Y's off into 2 6-inch ducts.
5.) The Hallway (middle-southern end of the house) vent is about 2 feet from the unit/return and is 6-inch directly from the plenum.
6.) The Kitchen vent is in the middle of the Kitchen (South Eastern end side of the house). It is a 6-inch duct to vent and is also direct from the Plenum.
7.) Last but not least Laundry Room South West side of the house has a 6-inch duct to vent which is also direct from the plenum.
So there you go! LOL Hope that helps and is not TOO confusing! LOL
