This chart compares the 5-year savings you can expect from
an XP19 heat pump vs. units with lower efficiency ratings. The
regions used to calculate household fuel and utility costs reflect
a cross-section of cities in the U.S. using 2006 Department of
Energy national average energy rates. In addition to geography,
cooling costs are based on 3-ton capacity specifications, with
1,600 cooling hours per year. Your actual costs will vary
depending on the weather, local fuel rates, systems settings
and your personal lifestyle.
Efficient Can save
hundreds of dollars each year
on utility bills
With industry-leading efficiencies of
up to 18.60 SEER and 9.30 HSPF, the
XP19 is the most efficient heat pump
on the market today.*** Nearly twice
as efficient as a typical†heat pump,
the XP19 can lower your utility bills.

Our dual-fuel
system offers
the perfect
combination of
efficiency and comfort with two
power sources—a gas furnace and
an electric heat pump.
What makes this system so ideal is
that it seamlessly alternates between
the two sources, depending on the
need. A heating and cooling system
all in one, the heat pump provides
the primary power (cooling in the
summer; heating on mild winter
days), cutting down on gas fuel
consumption. On cold winter days,
when the temperature drops to
freezing, the gas furnace takes over
to provide an extra boost of warmth.
††
Must be accompanied by either a variable
speed air handler or furnace and the
ComfortSense™7000 series Touchscreen
Thermostat

SOUND INTENSITY
In terms of sound, installing
an XP19 is like moving the
nearest neighbor up to
2-1/2 times farther away.
3
Quiet So quiet,
you won’t believe your ears
The XP19 is engineered with
exclusive SilentComfort™technology
for quiet performance. A patent-
pending fan design, two-stage
operation and an insulated
compressor compartment also
keep sound at a minimum.
SUPERIOR MOISTURE CONTROL
ComfortSense
™
7000 touchscreen thermostat removes up to 75 gallons per day when combined with select equipment.
Responsible
Conserves energy, while
preserving the environment
The two-stage scroll compressor
uses the R410A refrigerant, which
meets the EPA’s standards for ozone
and environmental safety.
When combined with a ComfortSense™7000 touchscreen thermostat†† and
Humiditrol®whole-home dehumidification system, the XP19 heat pump
can remove up to 75 gallons of moisture from the air per day without
overcooling your home like competing systems.
Customizable
Optimized for use with the
new Humiditrol®whole-home
dehumidification system
The XP19 gives you the flexibility
to choose a Humiditrol whole-home
dehumidification system for
improved comfort and indoor air
quality. The Humiditrol system uses
patented technology to provide a
level of humidity control never
before available.
The Humiditrol dehumidification
system also saves you money.
Dehumidified air feels cooler, so you
can raise your thermostat setting,
lower energy costs and still enjoy
great comfort. According to the U.S.
Department of Energy, you can save
5-7% on your monthly cooling bill
for every two degrees you raise your
thermostat.
The Humiditrol
dehumidification system also helps
to reduce the opportunity for mold
and mildew problems present in
humid conditions. It customizes your
cooling system, providing indoor air
quality you can feel.
††ComfortSense™is required for proper operation of the Humiditrol®system on split system air conditioners
and heat pumps. ComfortSense will not control the packaged rooftop unit version of the Humiditrol system.
