    Could be an old Williams or Air Ease outdoor unit. Or even an American Furnace (AFCO) that matched the furnace. They were green and front discharge.

    Judging from my literature, that model was sold for a long time in the 70s. Since it says American Furnace on it, I'd guess early 70s. Still got a Singer outside?

    The X13 doesn't increase speed to maintain CFM though. They'll drop CFM as static increases just like a PSC.

    Trane usually changes a letter to indicate a change in the unit, the letter after the 036 size. From what I can find, the 036C is communicating. Nothing I found on the 036E says it is.

    Is there an outdoor sensor that turns the unit over to gas heat in cold weather? Also ask them if they hooked up defrost heat to temper the cold air in a defrost.

    With return air that cold, flue gas will condense in the primary heat exchanger causing rust & corrosion. Don't know why the old one didn't warn you put it is an issue to be aware of.

    They just hang lose in the control compartment. The demand boards do let a lot of frost build up before they go into defrost. Sure beats the timers constantly defrosting a clean coil.
