    How would you seal the returns if they were in the stud bay like that - or would you do something else entirely?

    Doing some searching around, I've seen that the bare studwall plenum can be OK, as long as it is sealed. One method I saw was flushfitting drywall between the cavites and sealing the seams with...

    I see there are duct "silencers" on the market, but they look to be more for fan noise. In other conversations I've seen that a line of flex duct may significantly reduce the sound before it enters...

    Thanks for the links. One thing I'm having trouble with is figuring out how much CFM and the tonnage of the system - no AC BTW. One has me at 4 tons the other at 5 tons. HVAC Calc said 1 ton......

    My member ID here at aol dot com is where you will find me ;)

    I've got HVAC Calc and I think it mentioned a 1 ton unit for my 1700sq house (no AC). The duct sizes they were mentioning matched...

    Around here, it's hard to find a home that has been run with solid duct.

    I'm in the process of choosing a company for my furnace and ductwork install. I live in SoCal, if that makes any difference. My one request I have of each representative is that I get to see an...

    I've got a REALY old gas furnace - heat only style - it may be 40 years old. Yes, the heat exchanger is cracked, yes it will be replaced sometime soon. I've talked to this forum before about this...

    Thanks for all the info! That is exactly what I was looking for.

    I realized that our house is still under a 1 year warranty, so if I get lucky and the exchanger is cracked... did you ever think...

    Strangely, I have nothing to counter that logic - I like it!



    A little furry critter named "Snuffy" is greatly relieved to hear that. Curious how you would not touch the furnace wiring that...

    swampfox, I see. So when I call a someone who says they are a pro out to do this, and they come up with some strange way of doing it that involves a hampster, a razorblade, and 6 rolls of UL181 tape...

    "The heat side would not even be part of what you are wanting to do"

    Well... OK, but I would think that part of any system that would run the fan alone would also limit the ability of the gas...

    I appreciate that number breakdown trane. I'm sure that this unit will need replacing sooner rather than later. But I live in So Cal, not too far from the water - close enough to always have...

    trane, I guess I'm in luck then! I've spent no money on this furnace yet, and I know it doesn't come with a relay.

    I've been talking here about adding a relay, not using one that is already...

    rsmith46, adding a relay is exactly what I thought was neccisary. Using a 25v relay, which in the open position allows the normal heat circuits to run, including allowing power to the gas valve if...

    OK, I'll take a step back here for a moment. Could you (a Pro) convert a 2 wire heat only system to a 3 wire heat or fan system? Does this kind of thing ever come up? I ask this because the...

    What is a "fan center"?

    Also, when you say dangerous what specific dangers are you talking about?

    I want my thermostat to control the fan. The schemeatic on the furnace itself only shows a 2 wire hookup, but I could easily add another wire from the transformer to the thermostat, from there to a...

    Well, I've gotten my duct in and have my furnace and new thermostat up and running. Just in time!
