FEATURES
What is a Mini-Split?
Halcyon systems eliminate the need for a
basement or attic-located evaporator unit and
bulky ductwork by using thin copper tubing
that pumps refrigerant directly to discreet wall
mounted or concealed units inside. Even more
remarkable, this same unit works in reverse in
winter, absorbing heat from the outside air and
moving it indoors to heat your home. The
result? Efficient cooling and heating for yearround, whole-house comfort in most climates.
Available in numerous mix-and-match
capacities and configurations, there's a
Halcyon mini-split system for even the
most difficult to heat and cool areas.
How Does a Mini-Split Work?
Like your refrigerator, heat pumps use electricity to pump refrigerant and transfer heat from one space
to another. When we transfer heat from within our home to the outdoors, we call it "air conditioning".
Conversely, when we transfer heat from the outdoors to within the home, we call it a "heat-pump".

An electric heater converts electricity directly to
heat, and if we assume that the heat loss is zero,
the output from one kilowatt input is one kilowatt
or 3,400 BTU and the EER is 3.4.
Heat pumps are more efficient than some other forms
of heating because heat pumps do not actually create
heat - they just move it from one place to another.
For example, the output of an efficient 10 EER heat
pump is triple that of an electric heater.
Electric Heaters versus Heat Pumps
*EER (Energy Efficiency Rating) = Rated BTU capacity divided by total kW input.
Heat Pumps Provide Heat When it is Chilly
Because refrigerant is naturally much colder than outdoor
temperatures even on a very cold day, it actually absorbs heat
from outdoors, and transfers the heat it absorbs outside to
within your home. The refrigerant's physical properties do this
naturally. What you pay for is the electricity to pump refrigerant
via copper tubing from outdoors to indoors. Because we move
the heat rather than create it (as electric baseboard or resistant
heat does), we can deliver up to 4 times the heat for the energy
we consume!

Air Conditioners Provide Cooling When It’s Warm
Come spring and summer, simply reverse the process and
put the same system into "cooling mode" and transfer heat
from indoors to the outside. For many climates, the advanced
technology that goes into these units creates a far more cost
effective alternative to either gas or oil-fired units for heat, or
a central ducted system for air conditioning. Fujitsu’s mini-splits
come in both cooling-only models or heat pumps, which
provide both heating and cooling.

FEATURES
Whole Home or Business Comfort
Fujitsu's Halcyon HFI systems provide home
and business owners just the right amount of
heating and cooling needed by installing 2 to 8
indoor units connected to one outdoor unit.
Indoor units vary by size and style and each
creates its own "zone" of comfort, allowing you
to heat or cool individual rooms, hallways and
open spaces.

Ductless Technology
Don’t waste money cooling and heating the ducts
in your walls and attic. Fujitsu systems are ductless, meaning they install easily and won’t take
up valuable closet space. Since mini-splits have
little to no ducting, they forego those energy
losses typically associated with central forced-air
systems. Duct losses in a central air system can
easily account for more than 30% of energy
consumption, especially if the ducts are not
sealed tight or in an unconditioned space such
as an attic or crawlspace.

Rebates
To encourage customers to buy energy efficient products, many
local utility companies offer significant rebates for the purchase
of a ductless mini-split system. Go to Fujitsu’s web site to search
for local rebates, consumer loans and utility bill discounts. We
provide a listing of rebates and offerings on qualifying Fujitsu
mini-splits by state. www.fujitsugeneral.com/utility_rebates.htm
As much as half of the energy used in your home goes to heating and cooling.
So, making smart decisions about your home’s heating and air conditioning
system can have a big effect on your utility bills — and your comfort.
The high energy efficiencies of
Halcyon systems slash utility
bills by up to 25%. If your
average annual utilities are
$4,200, Fujitsu can save you up to
$1,050 annually or $10,500 in 10 yrs!*
Federal Tax Credit Up To $300 through 2013
A tax credit can provide significant savings. It reduces the
amount of income tax you have to pay. Unlike a deduction,
which reduces the amount of income subject to tax, a tax
credit directly reduces the tax itself.
Federal tax credits are effective for systems purchased
through December 31, 2013 for “Qualified Energy Property”
The federal tax credit for qualified equipment is 10% of the
amount paid but shall not exceed $300 for the qualified
energy property.
Fujitsu has 16 qualifying systems in 2013
Check with your tax professional for details and visit
www.energystar.gov and click on “Tax Credits” for additional
information.

Inverter technology is like cruise control for your
heating or cooling system. Compressors only run as
fast as they need to handle the cooling or heating
demand. They can handle greater extremes in
temperature, are smoother and more stable in
operation, and reach the desired temperature more
quickly than conventional air conditioners.
