Cold Air Return Info
 
5 Attachment(s)

Hi Paul,
Here is as much info as I could gather. SF of the room is 253 ft with 8 ft ceilings. Ceiling insulation is approx. R16 with 4" of cellulose on top of the batt insulation. SF of the outside cold walls is 165 sf. Original cement floor and covered with plywood subfloor (not sure if insulated or not). SF of 3 windows combined is 25 sf with Anderson double pane windows. The rest of the home is approx 1,800 sf. The bedroom has two heat vents that are ceiling mounted. I do not know the size or cfm of the heater but will attempt to upload pictures. The heater is a York GY9S080B12UP11G gas fired. I do have a vent mounted over the door facing the kitchen side of the house and that is the one tee'd into one of the 6" supply lines to the bedroom that I could remove and cut a grill opening on the bedroom side but would that be an issue up high? I do have room to cut grill openings approximately 6 inches above the floor height. Also, the 2 6" supply lines are flex duct with booster fans in each to increase the air flow. Would you recommend replacing the flex with hard duct due to increased friction of the flex?

Another cold air return question

HI Paul,
Thanks for the info! There are 5 wires coming from the blower to the board. Red is on a Park Tap, Yellow is also on a Park Tap, Black is on Low Cool Tap and Blue is on Heat. A white wire goes to a neutral block on the upper right side of the board. I'm attaching a picture of the board and taps. Thanks again, you have been a wealth of information and patient as heck!
Joe
