LG Duct-Free Split systems

Precise climate control

Made easy

Control you never thought
possible in every room of
your home.

Home Comfort Solutions by LG are Duct-Free Split systems that allow you to cool or heat your entire home
or just a single room without the need for invasive ductwork. There’s no tearing down of walls or altering your
home’s appearance. LG Duct-Free Split systems are simple to have installed. In most cases, a professional
contractor gets the job done in less than a day.

How LG Duct-Free Split systems work

LG Duct-Free Split air-conditioning and heating systems
consist of three basic components: an inverter-driven outdoor
unit, a stylish and quiet indoor unit that delivers conditioned
air to the room, and compact conduit for refrigerant lines
and wiring that connects the units. This design allows for
energy conservation by targeting only those areas that need
cooling or heating, a cost-effective feature when only certain
portions of a building are being used.

LG Duct-Free Split systems can be used virtually anywhere

LG delivers advanced climate control and operating efciency
to a wide range of residential and light commercial projects,
from a stuffy bedroom to a home addition where cooler
temperatures are required.

Applications may include:

• Older homes

• Sunrooms

• New home constructions

• Room additions

comforting innovation

Benets of Duct-Free Split systems

• Reduced energy costs—LG’s evolved technology
can make a difference in cooling and heating bills

• Incredibly quiet—With advanced motor and fan
designs, LG units operate at low sound levels

• Custom temperature control—Precise

temperature settings in each zone

• Beautiful design—Variety of elegant looks to

complement any decor

• Enhanced air circulation—Electronically
controlled louvers and fan speeds designed to
keep room temperatures consistent

The advantages of inverter technology

Inverter variable-speed outdoor units are measurably quieter and use less energy than conventional air
conditioners. Unlike conventional air conditioners that cycle on and off, an inverter compressor ramps up or
down to match the capacity and maintain comfort levels.

SEER: Your guide to cool savings

• High-speed cooling—Powerful Jet Cool
setting quickly lowers the temperature of

warm rooms

• Dependable heating—An excellent source of primary
or supplemental heating in the cooler months

• Built to last—LG’s commitment to quality means years
of dependable comfort

• Convenient controls—All indoor units include a

handheld or a wall-mounted controller

HSPF: For cost-saving coziness

An acronym for Seasonal Energy Efciency

Ratio, SEER is the industry-wide rating measurement

that conveys energy consumption information

to consumers. The higher the number, the more

efciently a product will produce cool air…and

operating efciency is a big step in conserving our

natural resources. Your contractor will be happy to

explain SEER numbers in greater detail, and help you

determine which LG Duct-Free Split system is best

for your unique requirements

.

Heating Seasonal Performance Factor, or HSPF,

represents the total heating output when compared

to the electricity used. Like SEER, the higher the

HSPF rating, the more efciently a product will

produce warm air. If you live in a climate that requires

heating in the winter months, as well as cooling in the

summer, ask your contractor to determine the ideal

Duct-Free Split system for you.

One room, wonderful solutions...
single-zone systems

Who needs ductwork?

Are you planning a new room addition? Do you have a space that never gets cool enough, like the bonus room over
your garage? Or warm enough, like the sunroom in the fall? In the past, homeowners have turned to window units,
or faced the expense of enlarging their central air-conditioning system. Now, there’s a proven solution to cool or
heat any room — an LG single-zone Duct-Free Split system.

Benets of single-zone Duct-Free Split systems

• Available in a full range of capacities for
all room sizes

• More energy efcient than window units

and central air-conditioning systems

• All-season use—heat pump models have both cooling
and heating capabilities

• Quiet operation, inside and out

• Usually installed in less than a day

• Many units are ENERGY STAR® rated

• Twelve models were awarded the ENERGY STAR®
Most Efcient designation for 2014

ENERGY STAR® is a joint program of the U.S. Environmental Protection

Agency (EPA) and the U.S. Department of Energy (DOE) created to

promote energy-efcient products and practices. The ENERGY STAR®

logo helps homeowners identify which products meet energy efciency

performance levels set by U.S. EPA and U.S. DOE
