Air Handler Can Be Installed In The Following Configurations:




Did you know you can extract heat from chilly outside air and use it to heat your house? This feat is performed by the magic of a heat pump--an appliance that uses refrigeration technology rather than fuel combustion to provide warmth and cooling. Heat pumps are not new-- they've been in use for more than thirty years. But upward-spiraling energy costs and technological breakthroughs have catapulted heat pumps into position as a popular, sensible alternative to conventional heating and cooling systems.
Heat pumps transfer
heat from one place to another--providing both heating and cooling. They
work on the fundamental principle that heat exists in air even at extremely
low temperatures--down to -460 degrees F. In the winter, a heat pump extracts
heat from outside air and delivers it indoors. To cool a house on hot
summer days, it works in reverse, extracting heat from room air and pumping
it outdoors. The most common type of heat pump is an "air-source"
system. "Split" air-source systems have an outdoor unit which
includes a compressor, outdoor coil, fan and reversing valve. That unit
is connected with refrigerant-filled tubing to an indoor component. The
indoor unit contains a fan, indoor coil and a supplemental resistance
heating element. Depending on whether the heat pump is in a cooling or
heating mode, the refrigerant moving through the system makes the indoor
coils either hot or cold. A blower draws room air in through a filter
and pulls it across the indoor coil.

The indoor part of a central air conditioning or heat pump system that moves cooled or heated air throughout the ductwork of your home. An air handler is usually an electric furnace or a blower coil.
Air-source heat pumps contain two separate heating systems: the heat pump itself, and heat strips. Heat strips are electric resistance heating coils located inside the indoor air handler, the portion of the system which circulates the indoor air. They look much like the coils inside a kitchen toaster. The heat pump itself is energy efficient and will heat the home at little expense.
The heat strips operate in three different modes:
De-icing - Also called defrost cycle. During winter the evaporator coil in the outdoor compressor unit becomes colder than the outside air, so water often condenses on it and freezes. To remove this ice the heat pump automatically switches for several minutes to the air conditioning mode, which raises the temperature of the frozen coil, melting the ice. During de-icing, heat strips operate to keep the system from cooling the home.
Auxiliary Heat - When
outdoor temperatures drop below 40 degrees, a properly-sized heat pump
by itself is not able to furnish all the heat the house needs. In the
auxiliary mode, heat strips operate simultaneously with the heat pump
to provide the additional heat needed for the home. The auxiliary heat
mode is activated by a second temperature
sensor inside the thermostat when the house temperature falls more than
a few degrees below the setpoint. This includes when someone adjusts the
thermostat setpoint.
Emergency Heat - Emergency heat can be activated by a manual slide switch
located on the thermostat. This mode is used when the heat pump compressor
has failed. It turns off the heat pump to prevent further damage and turns
on the strip heat to continue heating the house.
Determining the heat strip size to order with your new system:
Ask your installer what size heat strip kit to order with your new system. If you have an existing system and are replacing with a like size new system you can check your main breaker panel for the fuse/breaker size that is currently running the air handler.


Look for a label in the breaker box for the breakers that handle the current unit. This will normally be labeled "AHU", "Furnace", "Air Handler" or "Heater". The breaker will be a 2-pole 208/230 breaker as shown above. By checking the numbers on the end of the breaker you can compare to the following list for sizing your heat strip kit. If each breaker is labeled 45, that would support a 8 kW heat strip. The amperage is the number on the end of the breaker and not the two added together. If you need assistance, please call us and we will be happy to assist you.
5kW-30 Amps, 8kW-40 Amps, 10kW-60 Amps, 15kW-90 Amps and 20kW-120 Amps
Note: Heat strip requirement may increase if you are replacing your system due to adding square footage to your residence or if your original system was undersized.
Rheem Manufacturing has been a trusted name in the United States for many years. One of the world's leading manufacturers of central heating and cooling products, Rheem distributes its full line of residential and commercial products around the globe.
Rheem Manufacturing Company was established in the mid-1920s when brothers Richard and Donald Rheem acquired a galvanizing plant in San Francisco, California. They opened another plant near Los Angeles a decade later and began manufacturing water heaters. By 1936, Rheem had coast to coast distribution, and during the 1940s and 1950s, increased its product line to include space heating units for homes, oil furnaces and air conditioners. As the company grows, it continues to expand its line of residential and commercial products worldwide.
What is ARI?
The Air-Conditioning and Refrigeration Institute (ARI) is the national
trade association representing manufacturers of more than 90 percent
of North American produced central air-conditioning and commercial refrigeration
equipment. ARI's national headquarters is located in Arlington, Virginia,
at the Ballston Metro Stop, just minutes from downtown Washington,
DC. ARI traces its history back to 1903 when it started as the Ice Machine
Builders of the United States. ARI was formed in 1953 through a merger
of two related trade associations. Since that time, several other related
trade associations have merged into ARI, making it the strong association
that it is today. Over the past 45 years, ARI has emerged as the major
voice for the air conditioning and refrigeration industry.
ARI Standards
As
one of its most important functions, ARI develops and publishes technical
standards for industry products. ARI standards establish rating criteria
and procedures for measuring and certifying product performance. In this
way, products are rated on a uniform basis, so that buyers and users can
properly make selections for specific applications. Standards are developed
by individual ARI product sections and other interested parties who wish
to participate, then approved by ARI's General Standards Committee. The
more than 60 standards now published are mainly performance-rating standards,
although some are application or terminology standards. Many ARI standards
are accepted as American National Standards. ARI actively participates
in developing international standards and has established a policy of
adopting international standards for use in the United States, when practical
and feasible. ARI is cooperating with the Canadian Standards Association
(CSA) and other groups to establish joint ARI/CSA rating standards and
common U.S./Canadian safety standards.
Performance Certification
In its certification programs, ARI
verifies manufacturers' certified performance ratings of industry products
in continuous and extensive laboratory testing. Each product section,
with the support of the ARI engineering staff, may develop certification
programs for its eligible products. Participation in the programs is voluntary
and is open to non-members of ARI on an equal basis. ARI annually selects
a significant portion of each manufacturer's production models to be tested
by an independent laboratory under contract to ARI. Units, randomly selected,
are tested using procedures stipulated in the corresponding ARI standards,
to verify that they meet the manufacturers' certified published performance
ratings.
