Trane Ductless Systems.
Whatever their specific heating and cooling
needs, people trust Trane to provide reliable,
efficient solutions. Trane Ductless Systems allow
you to create a comfortable indoor environment
in spaces where adding ductwork might be
impractical or too expensive, or not as efficient
as a ductless option.
• Retrofit a house that doesn’t have a
ducted system or where the central
system is already at capacity.
• Bring efficient, economical comfort
to new room additions.
• Provide spot heating and cooling
that operates independently of
the central system.
• Utilize ductless efficiency for new
construction projects where ductless
systems make more sense than a
traditional ducted system.
• Customize multi-split systems to
supply flexible and cost effective
zoning solutions.
Easy to install Trane Ductless Systems offer flexibility
in design and provide efficiency and economy
with two simple components – an outdoor unit
and one or more stylish, low profile, indoor units.
All built with Trane’s legendary reliability and
innovative thinking.

with a Trane Ductless System.
Air ducts from a central forced air system can
lose energy, especially if the ducts run through
unconditioned areas like attics or basements. Since
Trane Ductless Systems may not require ductwork,
they avoid that energy loss, reducing your impact on
the environment and lowering your energy costs.
System efficiency is measured in SEER, which stands
for Seasonal Energy Efficiency Ratio. Similar to
miles per gallon in a car, SEER measures the overall
efficiency of a heating and cooling system on a
seasonal basis. The higher the SEER, the greater
the system’s energy efficiency, and the lower the
overall carbon footprint of your household.
With SEER ratings for Trane’s Ductless indoor units
ranging from 16 to 22, our ductless systems are
remarkably efficient and environmentally friendly.
Saving energy simply and sensibly.
Annual savings for cooling your home
based on the efficiency of a
matched system.
Like miles per gallon in a car, the higher the
system SEER rating, the more comfort you
will get from each energy dollar.
* Minimum efficiency established by the Department of Energy. Potential energy savings may
vary depending on your personal lifestyle, system settings and usage, equipment
maintenance, local climate, actual construction and installation of equipment and duct system.
Trane Ductless Systems are great for rooms or
areas that are separate from the central system.
You have the ability to customize your system
to provide efficient, reliable, heating or cooling
zones for any room in your home.

Energy Efficiency
Trane ductless systems use variable-speed inver ter technology. This
allows the compressor to continually modulate and adjust to the
most efficient speed to meet your demands.
The variable-speed inverter technology used in Trane ductless systems is
up to 35% more efficient than a conventional single-speed compressor.
Higher EER/COP levels allow you to reach the desired temperature
quickly without sacrificing your electricity bills.

Trane Multi-Split Systems, one system, multiple options.
READ ONLY
You can connect up to five indoor units to just one
outdoor unit from Trane to provide exactly the degree
of comfort you require. Because there are no ducts,
indoor units can be installed in a room at the front
of your home while connected to an outdoor unit
located inconspicuously at the rear or side.
•Mulit-split systems allow the most flexibility
when customizing a comfort system for your
home. Mix and match indoor units to meet
the needs of each room. Consider additional
ports for expanded usage at a later date.
•Multi-split systems provide the benefits of
a zoning system without the costly additions
of zoning hardware.
•Up to five indoor units with separate
temperature zones can be connected
to one outdoor unit, improving comfort
and saving energy.
You’ll feel the difference with Trane.
Space-saving low profile indoor units can be wall,
floor or ceiling mounted, providing great flexibility
in interior design or space utilization and a
customized comfort solution.
•Multi-split heat pumps are an affordable and
energy efficient way to control the climate
of individual rooms.
•No energy loss due to air leakage in ductwork
from heating or cooling the entire duct system
before the air reaches desired rooms.
•No expensive ductwork required. The multi-split
system adjusts to your needs, providing constant
comfort and energy savings.
Trane Ductless Systems allow you to provide comfort exactly
where you need it in your home, but they don’t stop there.
The “I Feel” function on the wireless controller takes comfort
and convenience to a very personal level. “I Feel” means that
you control the temperature right from the controller. The
temperature is read from where you and your controller are.
It’s total control, at your fingertips.

Trane’s triple filtration system allows you to breathe easier.
READ ONLY
At Trane, we know that the quality of the air
your family breathes is as important as the
comfortable temperatures they enjoy. Air
that’s full of particulates can not only feel
uncomfortable, it can cause breathing problems
for family members and exacerbate existing
respiratory problems like asthma and allergies.
Every Trane ductless indoor unit comes with an
Auto Clean feature that reduces moisture and
inhibits the development of bacteria to begin
Polluted Air
with, but we go far beyond that to provide
triple filtration that keeps the air you breathe
clean. First, a standard filter traps dusts and
other common particulates; second, an active
carbon filter absorbs both physical debris
and chemical pollutants. And a third level of
filtration, a catechin additive filter, provides
anti-oxidation and sterilization to absorb and
eliminate odor and bacteria.

Unique Catechin Filter
An additive abstracted from natural green tea,
catechin, provides long-lasting sterilization
of dust, removing up to 95% of potentially
harmful bacteria.
