What about the DS? It's got that touchscreen.

I added a damper at the main HVAC trunk that comes off of the furnace to the 12" run that supplies downstairs and that fixed the heat issue in the bonus room. Now there's some extremely long runs that aren't on that trunk that feed the opposite side of the house that have poor air flow...

The bonus room is fully insulated. The sides with the attic crawlspaces are insulated with R19 and the cieling is insulated with blown cellulose to R19 as well. My HVAC buddy and my home inspector both said the 3 ton unit was within spec for this size home and this area. What would you like...

Do you have AIM? I'd like to talk to you a bit more.

I'm afraid I don't have enough historic data to answer your question completely. As it sits, the bonus room is WAY too uncomfortable and is probably 4-6 degrees hotter than the other rooms upstairs. Should I run another 6" duct to the room or run a 12 or 14 and then split 2 runs off of that...

Please tell me how I can fix the problem. I have access to pretty much all of the ductwork upstairs and most of the ductwork downstairs. Even if it's multiple hundreds of dollars it'll be cheaper than my A/C compressor running every 3 minutes.

I went up in the attic last night and rooted around. Right off the air handler, there's a big rectangular duct and then there are other flex ducts off of that to feed the rooms. Here's where I think a major problem is. On the top of the rectangular portion there's a really big duct that comes...

So it's a wall-mounted unit similar to what would normally be a window-mounted unit but the parts are distributed? Would running a bigger duct to this room and splitting it off to two registers help?

My HVAC buddy said that the ducting adds up to the tonnage of the unit but it's distributed oddly. He also said the return vents still allow for positive pressure in the house(which is desired). dscline: What's a minisplit?

<edit> IVB </edit>suggested I sign up and post this question here. I just bought a new house and the temperatures range dramatically in the house. The foyer is 2-story and the living room is 2-story. When you walk up the stairs, the foyer and the living room are open on the second floor so...
