I'm really curious about what new construction homes do if they don't have the doors vented or cut too high off the floor.
Guess I'm hoping that some cool stuff can be done with thermostats or something like that.....
supply airflow." I tried loading it up again and for some reason the doc.
The return air on the main bedroom, with the pressurizatino problem, is not too small - it's about 10X20. After all, our guy was really nice and honest and hard-working, but this issue requires more technical expertise than he had, apparently.
Got a clue about how to find someone really knowledgeable? If you have a zoned system you should have some sort of Barometric Pressure Relief Bypass Duct, if not you sure will be having issues with Pressurization in some rooms, unless you maybe have a dedicated return for all rooms, if your in a pretty humid area you could also get your tech to look at slowing down the CFM's to 350 per ton., or is this a VS air handler?
A little while back I found this on building science and it talks about transfer grills "Transfer Grille From Builders Guide, Building Science Corporation All supply registers should have clear access to a return grille in order to prevent the pressurization of bedrooms and depressurization of the common area.
Bedrooms should either have hard-ducted returns, or another means of pressure relief, such as transfer grilles (above) or jump ducts (below).
Undercutting the door seldom provides adequate pressure relief.
Refer to Transfer Grille Sizing Table to compute required free area (and grille size) vs.not much was mentioned about equipment except it was a Trane system.Meeting new people over random chat portals happen to be fun, and with the modern portals random video chatting is somewhat safe too.Guess I'm hoping that some cool stuff can be done with thermostats or something like that..... There is a return air in two of the bedrooms, but I'm sure that's not the same as a jumper duct. We have joist or attic space available for all three bedrooms in question.Can anyone give me a little more detail on what a jumper duct is so I won't sound like the newbie I am when contacting an A/C professional? Is when you install a register in the room, and then run a duct out to(in your case) the hallway.However, what happens is that when a bedroom door is closed, it'll get too hot because the thermostat is not in that room.
