    There is a jumper that must be present on the furnace control board. I don't remember which contacts it is for sure. I think it's in the manual, but it doesn't exactly jump out at you in the setup....

    Let's Talk About Setbacks

    Say we have two days in a row, identical conditions (temp/humidity/thermostat set points, etc.) From purely an electrical consumption standpoint, which situation is better (assume "sleep" and "wake"...

    I should qualify that my system has very short runs, both supply and return. It has probably made it easier than most others would find to solely increase my cross sectional area in ducts and reap...

    I've a story to tell about my install that you may find interesting. It's not directly related, but based on some of your duct dimensions, it could be helpful. I'll post it when I get home from...

    Depends on what you paid in taxes. Also, I think I read somewhere that you can split the credit amount between 2009 and 2010 if you wish. Don't quote me on that. Best to talk to a tax...

    Pretty sure he's talking about the BTU output of the furnace quoted.

    Yours is rated for an output of 82,000 BTUH in 1st stage, 125,000 BTHU in 2nd Stage.

    For a comparison, in my 4-ton system,...

    If you haven't tried Evans yet, I strongly suggest you get a quote from them. Ask to speak to Leigh, and let him know you care enough to research more than the average Joe.

    Thanks for the tip, he's checking on pricing for me.

    Am thinking we'll probably go with:

    Due to costs, I am probably leaning toward the quoted arrangement with the 15 seer a/c (after I get him to change the coil to 5-ton). It would be hard to swing the 16 seer unit I think. I'll ask...

    So I figured out that the 15 Seer A/C isn't matched with that 4-ton coil, it should be matched with the 5 ton coil.

    I'll have to get him to change that.

    Ouch $$$$

    And I would have to stay with at least this furnace?

    That will probably be more than we can afford.

    I guess I'll play around with a furnace alternative for the 13 and 15 seer a/c. ...

    It says 1300-1450 for the low and medium-low settings on high stage. If that is the case, do you think that duct arrangement will work alright?

    The goal in the duct work is to take a partial load...
