Again, thanks to all the answers....
The furnace is great and just like in MLD's response, we too have had more
even temperature with this furnace.
We will call the local Trane tech and see if our mission of increasing the
fan speed can be accomplished.

It sounds as though your furnace is working properly, but there are ways
to
increase the fan speed on most models without increasing the amount of
fuel
being burned. Most newer Trane equipment only runs the fan half speed
when the
fan switch is set to the "on" position with no cooling call. Your local
Trane
tech should be able to figure out how to make the controls within the
furnace
bring the fan on in high speed with the "on" position on the stat.

Thank you for your kind responses to our question.

We thought that maybe it was possible to just increase the fan speed and
air
output without increasing the fuel consumption. Our goal was to increase
the
air circulation via increasing the fan speed/air output. Apparently this
can't be done without affecting the fuel being burned.

With our previous furnace, we would sometimes just put the fan on manual
(not burning fuel) to let the air circulate in the house (especially
between
seasons when it's no longer cold enough to have a furance on, and not yet
hot enough to turn the air conditioner on). With the Trane, the first
speed
is so low that it is barely noticeable when we go to manual fan. Soooo,
alas, apparently the days of manually putting the fan on ... with high
fan
speed air circulation, without burning fuel ... must be gone.

We have a high efficiency Trane furnace (2 speeds)
Is it possible to increase the speed of the fan output?

The first fan level seems very low to us, and it is rare for the
second
speed to come on (it has to be very cold day for this 2nd speed to
start
up).



This is Turtle.

When the furnace is running on first stage it is burning 1/2 the fuel
and
electricty of the second stage. If you can get by on the
first stage , you getting by with a lot of fuel not being burnt. Now if
you just want to see the furnace burn more fuel. Call the
service company and tell them that you want to run the furnace on high
fire or high heat and they will switch the wires out and make
it burn more fuel for you. I have never heard of one of my customers
wanting to burn more fuel in my life, but there is a first time
for everything.

Let me explain to you something here. The second stage is a higher
speed
on the fan but it is also a high level of the burners that
comes on and burns twice as much fuel as the first stage. It is not
just
the fan speed but the fuel rate goes up with it.
