NO!
Variable speed blowers will be completely unsatisfactory if they are
installed in a ducting system that is not pressure-balanced.
When the blower runs at 10%, if the system is not pressure-balanced
(which is done in the design phase), you can have registers near the
furnace putting out 15% and those at the farthest reaches putting out
5% instead of the expected 10%.
This means that you will have more heat than is required near the
furnace and less heat than required further away.
You also need the controls to manage the blower sp

Despite my house having been custom built, there are some weird
things about it that would lead one to believe corners were cut to
save $$$ or increase the builder's profit.
One of these anomalies is the 80% efficient furnace (the house was
built in 2003).
I have a local HVAC guy that is working with me to replace the
furnace, as I don't care to have $350/month gas bills in the
coldest part of the winter. Right now he has presented me with
about 4 choices, ranging from 95% efficient furnaces with "regular"
blowers up to 98% efficient furnaces with variable speed blowers.
I am considering the mid-range models that are 95% efficient with
variable speed blowers, as I have issues with stratification in the
house and am told the variable speed blower will help with this.
I would be interested in anyone's input if they have any direct
experience with such furnaces or know someone who does....
