How It Works
Live in a cold climate?
Even in outside temperatures as
cold as -13º F, our Hyper-Heating
INVERTER
®
(H2i
®
) technology will
keep your home and business
comfortable. Well-suited for
climates in the northern half of
the United States, H2i systems
continue to provide heating
when temperatures drop well
below zero.
H2i plus
™
takes
hyper-heating
technology to
a new level providing 100%
heating capacity down to -5°F
outdoor ambient (without wind
chill) temperature.
Technology that puts
comfort in your hands
The essential components of a zoned air conditioning and heating
system are the outdoor unit, the indoor unit and the smart comfort
controls. The system operates by transferring heat to and from an
outdoor unit to one or more indoor units. The units are connected
by pipes containing refrigerant, a substance that absorbs heat.
In cooling mode, the refrigerant absorbs heat inside the home and
produces colder air by transferring refrigerant from the indoor units
to the outdoor unit, where the heat is expelled.
In heating mode, the process is reversed and the refrigerant absorbs
heat outside of the home and provides warmth by transferring the
refrigerant from the outdoor unit to the indoor units. This method of
heat transfer — which works even in freezing weather — is powered
by electricity and is much greener than conventional systems that
burn fossil fuels during heating.
The outdoor unit is equipped with an INVERTER that enables it
to quickly change the amount of power it uses and the amount
of refrigerant it transfers to and from the indoor units. With the
INVERTER, the outdoor unit only uses the precise amount of power
needed to reach each zone’s preferred temperature.

transfer between the
outdoor unit and indoor unit
during heating operation.
