    Yep. That's a pisser. I listen to them just about every day. And, unfortunately for me, I never got a chance to see them in concert. :(

    Air can only go in to the system if the system is out of refrigerant, in which case, what does it matter? A hose full of air at 0 psig will not flow into a system that has a positive pressure.

    I was thinking that both stages were energized during second stage heat, thereby energizing the solenoid valve and stage 2 coil simultaneously, which should give a higher amp draw.

    Heat anticipators and 2 stage furnaces

    Never really paid attention to this. I was checking control circuit amp draw on a 2 stage 90% Trane to set the heat anticipators (W1 and W2). I got an amp draw of .35 on first stage heat and .25 on...

    A metric crescent wrench?
    All kidding aside, a combustion analyzer that never requires factory sensor replacement or recalibration would be nice.

    Motard, short cycling a furnace is also a waste of money. When the unit first fires, the blower is generally delayed a bit to allow the heat exchanger to warm up. During this warm up, most of the...
