Where to place T in down run for 2 floor registers?
I'm refinishing my basement, installing a bathroom and putting 2 heat registers off one down run, one to the bathroom and another to the adjacent room. I put a T in for the down run that goes straight down to the bathroom adding a right angle register at the floor. The down run is 4" coming off the 5" that feeds the kitchen above. My question is where should I put the T, at highest, mid or lowest point of the 4" down run? The next room is like <3' over and it will also have a fight angle floor register.
BTW, the basement heats up really fast so both registers will be probably close to 3/4 closed if that makes a difference and the Trane XV90 can easily handle it.
I have a semi-finished garage - the 3rd car portion was framed, insulated, drywalled plus electrical years ago before I purchased the home. There is a door separating the main garage from the 3rd car. This 3rd car garage is now our Media room. I live in coastal San Diego area, and don't yet require AC in my house. I have a whole house fan that I'm pretty happy with. However, this 3rd car garage/media room does get pretty stuffy since there is no ventilation.
I'm thinking of adding some passive thru-the-wall ventilation to allow my whole house fan to suck cooler air from my main garage (which is already ventilated). I was planning do something like 12"x12" Air Return and Air Register. Any recommendations on the right way to DIY this one?
I understand the difference but what would benifit my house more? 2 floors, 1923 home. 1st floor is kept at 76 when its above 80 but second floor is easily 5 degrees or more hotter than first. Would venting the hot air out of the insulated attic help cool second floor or should I use a whole house fan? My theory is draw the hot air from the above space will help the space below. Opions , facts?
