technology maximizes your
comfort while minimizing sound
The variable speed motor ramps up
to speed slowly, so there’s no sudden
blast of air at startup. A specially
insulated cabinet further reduces
operating sound.
Healthier
Slowly circulates air for better
indoor air quality
When you set your thermostat to
“FAN,” the O23V continues to
slowly circulate air throughout your
home. That means you can run the
fan constantly without substantially
increasing operating costs.
It also means better indoor air
quality—low-speed fan operation
increases the effectiveness of your
filters, allowing them to capture
and remove more contaminants.
This chart depicts potential energy savings you can
expect from the O23V furnace versus older furnaces with
lower efficiency ratings. Criteria used in this example
are 2,000 full-load heating hours, with a 80,000-Btuh
heating design load and $1.90 per gallon for oil. Your
actual savings will vary depending on the weather, local
fuel rates and your lifestyle.

Efficient
Delivers significant energy
savings all year
The O23V has a heating efficiency
of up to 83% AFUE. Compared to
an older furnace, the O23V can
dramatically reduce your utility bills.
As an added benefit, the O23V’s
variable speed motor uses about
two-thirds less electricity than a
standard motor. During cooling
operation, this typically results in an
efficiency gain of 1 SEER (Seasonal
Energy Efficiency Ratio), which can
add to your energy savings.
