multi-zone units let you condition one up to
ve rooms with just one outdoor unit (depending on model).
The contractor can design a system that best meets the load
requirements of each room being conditioned because indoor air
handlers can be mixed and matched—all ve types of units shown
can be used in the same installation.
These 9,000, 12,000, 18,000, 21,000 and 24,000 BTUH indoor
units can be mixed, up to the point that their combined capacity
reaches the total allowable system capacity—see the chart inside.
All units must operate in the same mode except “fan” only can
always be selected. True zone control is possible because each air
handler operates independently and has its own wireless remote.
InverterFlex
®
models incorporate all the advantages of twin
rotary inverter compressor technology. The compressor speed is
variable, depending on the load demand. Most of the time the unit
runs at low frequency, saving energy while maintaining comfort,
but ramping up to higher frequency when needed. Temperature
uctuations and compressor on/off cycling are eliminated, and
indoor air quality is enhanced because air is constantly being
pulled through the lter and dehumidied.
InverterFlex
®
systems are also great for larger spaces such as
fellowship halls and commons areas: install multiple units for quiet,
efcient, easily controlled comfort.

In recent years, heating and cooling manufacturers have
made signicant advances in the efciency of systems
in terms of energy usage. This is an especially important
purchase consideration as fuel prices continue to rise.
Cooling efciency is measured by a Seasonal Energy
Efciency Ratio (SEER) rating. The higher the number,
the more efcient the equipment. All Comfort-Aire
InverterFlex
® systems are rated at 16 SEER.
Heating efciency is shown by a Heating Season
Performance Factor (HSPF). This is an estimate
calculated by dividing the seasonal heating output by the
seasonal power consumption in watts. InverterFlex units
are rated at 8.20 HSPF, which is considered very good.
All heating and cooling equipment comes with an
Energy Guide label which shows the estimated energy
usage—you can use these labels to compare equipment
efciency. Your dealer can help you determine which
system is best for you, taking into account a number of
factors including the average number of yearly cooling
and heating days in your area of the country, in addition
to your individual needs.
When you buy Comfort-Aire products, you’re purchasing
the peace of mind that comes from dealing with a
company that has a long track record of success. We have
a well-deserved reputation not only for quality products,
but also for standing behind these products with excellent
warranty and support programs. Also, you’ll nd our
web site is a convenient resource: owners’ manuals can
be downloaded and your installer can access technical
information and service manuals.

The total capacity for ALL indoor units cannot exceed
150% of the stated condenser capacity. For best
performance, the indoor units’ total capacity should be
100% or less of the condenser capacity. When a system
is sized beyond 100% of the condenser capacity, the
Indoor Unit Mix ‘n’ Match Possibilities
compressor may not provide full capacity for all indoor
units: sizing above 100% is generally specied when one
or more of the indoor units will not be in use most of the
time. Also, the total capacity for ALL indoor units cannot be
less than 50% of the condenser’s capacity.
