Economical Gas Heat
Islandaire EZGS PTAC units provide high-efficiency gas
heat. Gas-heated air is much warmer than conventional
heat pump units, allowing the unit to reach set tempera-
ture levels much faster. The compressor operates only
during the cooling cycle, reducing noise and extending
the life of the compressor.
Guaranteed Quality
Each Islandaire unit is designed to operate quietly and
efficiently and is backed by the best warranty program
available. Our standard warranty is for one year parts
and labor, including a five year compressor part only
warranty and a lifetime warranty on the heat exchanger
part only OR a two year parts only warranty, including
a five year compressor part only warranty and a lifetime
warranty on the heat exchanger part only.
Whether it is an exact replacement unit or a new con-
struction project, Islandaire is the smart choice for all
your air conditioning and heating needs.
Application
Considerations
It is important for air conditioning systems to be prop-
erly sized for each application in order to achieve desired
temperature and humidity levels. It is strongly recom-
mended that a professional engineer match the PTAC
unit with the building structure and climate.
The following application considerations are all impor-
tant in choosing the proper PTAC system for the build-
ing structure.
UNDERSIZING
If a PTAC unit is undersized (cooling capacity is less
than required capacity for an application), the unit will
not be able to cool the space down to the desired tem-
perature during very hot days.
OVERSIZING
If a PTAC unit is oversized (cooling capacity is greater
than required capacity for the specific application), the
unit will cool the space down to the desired temperature
too quickly creating a cool, yet excessively humid space.
AIR INFILTRATION
Excessive air infiltration can intensify problems associ-
ated with under-sizing or over-sizing a PTAC unit. This
can be the cause of insufficient cooling, dehumidifica-
tion, or heating. Sources of air infiltration include vents,
gaps around windows and doors, and improperly sealed
floors, ceiling or wall joints.
