Hi,

I need some thoughtful thoughts about blower speeds.

First the facts: I have a Sears 105,000 BTU / 84,630 BTU natural gas
furnace in a 1,900 sq ft 2 story house.

The thermostat is a Honeywell programmable with "fuzzy logic".

The blower speed is currently set at "Med-Lo" which is about 1,100
cuft/min or 70% of maximum (1,500 cuft/min) volume.


Question: Would the furnace be more efficient at a higher blower speed?

If so, is there a benefit from adding an outdoor temperature sensor to
trigger the higher blower speed when the outdoor temperature falls
below,
say 45 degrees F.?

Any thoughts will be appreciated.

Tom
