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 year-

round, 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

Individual Zoning: Personalized Whole Home Comfort

Halcyon HFI Systems are some of today’s most advanced forms of heating and air

conditioning. One outdoor unit can operate up to 8 indoor units simultaneously. Fujitsu’s

HFI Systems are super quiet as well as highly energy efficient.

Each indoor unit can be operated independently via remote control

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 duct-

less, 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.

A Year Round Solution

Revolutionary Halcyon heat pumps provide

both heating and cooling for year round comfort

in most climates. A simple push of a button on

the remote control allows you to switch from

heating to cooling (or vice versa) automatically.

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.

FEATURES

Comfort and Convenience

Flexible and Quiet

Mini splits offer flexibility because they can

be suspended from a ceiling, mounted flush

behind a drop ceiling, hung on a wall or floor-

standing. Ductless heat pumps allow for a

peaceful inside environment by enabling the

contractor to install components like

compressors and motors outdoors.

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. Set
