I'll be sure to post pics once they are done.
Also, I have been thinking about taking the next logical step and setup zones as well. Here's a revised drawing of the 1st floor of my house, showing how I was thinking about zoning it. The orange rectangles represents all the registers on the main floor. The blue is my single return, and the green is where the XL950 is mounted.
My understanding is that for zoning to work properly, all registers needs to be dampened somehow, right? The main issue we have right now is that the kids room (zone 3) is always very cold and I have to keep the thermostat set at 72 all night long to keep it in the mid 60s in there. I got 2 little girls, 4 months and 19 months.
Zone 4 is my office and there are computers running all the time, so it gets really hot with the tstat set at 72. But in the summer time, I need all the cooling I can get in there.
Zone 2 is the master bedroom, and it also gets uncomfortable warm at night, and this is with 2 of the 3 vents manually shut. In the summer time, I need all 3 vents going to keep in cool.
Zone 1 is the rest of the house, which does not really need heat (or cooling in the summer at night), but I don't don't have a choice right now since that is where the tstat is located and I do want heat in those rooms during the day. I tend to keep the registers in the panty and 1/2 bath closed in the winter and open the one in the 1/2 bath in the summer.
I'm thinking about getting them to give me a quote for adding zoning to my new system. From what I can tell, I would need 8 6" round retrofit dampers for zones 2-4 (Trane Part # ZDAMPRRMA0006A) and then a single bottom mount 10x20 damper (Trane Part # ZDAMPBMMA1020A) for zone 1. And of course 3 sensors for zones 2-4. Either wireless or wired, depending on cost. And finally the ComfortLink II Zoning Assembly (ZZONEPNLAC52ZA) which I believe includes discharge air sensor, static pressure transducer and housing, supply & return air static probes and connecting tubing. Would I need any additional mixed air sensors?
Given my issues and layout, does adding zoning make sense in my case? If so, I want to make sure I tell them exactly what I should get so that they don't mess it up the first time. I think that by not heating/cooling zone 1 at night at the levels I'm force to right now, it will make a significant difference in my energy consumption.
