    Concord 90+ Furnace puts out cool air
    Please help -

    This unit has never put out warm air since the day it was installed however it does keep the house warm. Please note: it is a downdraft unit, slab home (perimeter heat). I noticed no improvement in my fuel consumption either. With the Burner box cover removed the flame is blue and seems very efficient.

    My thought is to rejet for a hotter flame - is it possible or can I be missing something?

    Thanks!

    I guess I don't under stand. The heater has never put out warm air but it keeps the house warm? Have you had it checked to see if its burning right(gas pressure)? If it's a two speed furnace is it going into high fire? More info if you can give it to us.

    Crazy huh? The vents get cooler and cooler the further away you get from the unit which I'll assume is somewhat normal for a downdraft unit on a slab home but the air just doesn't feel very warm even at the closest vents.

    No I haven't had the pressure checked but it appears to be an efficient flame. I believe it's a single speed unit because I have slowed the blower speed down by switching wires.
