does SEER stand for?
SEER stands for Seasonal Energy Efficiency Ratio. The higher
the SEER rating, the more efficient the system utilizes electricity.
SEER ratings of 6.0 were common just over a decade ago but
modern systems usually offer SEER ratings of 10-14 and as
high as 17.
have just purchased a high efficiency system but my utility
bills continue to rise.
Aside from rapidly increasing energy costs, many consumers
use their new energy efficient systems a great deal more than
their previous systems. Such increased usage can easily cost
more than operating older, less efficient systems on a sparing
basis. Energy ratings are however, a good indicator of where
a system ranks within its class of air conditioning and heating
units. All things being equal, a 14 SEER, or high efficiency
system, will cost less to operate than a 10 SEER, or less
efficient system. The difference in purchase price most often
results in considerable energy savings over the life of the
system. A knowledgeable technician can help you make an educated
decision about which system to invest in.
are Ultron® air conditioning systems?
air conditioning systems utilize a refrigerant known as 410a
as opposed to R-22 (commonly known as Freon - Freon is actually
a brandname but the name has been adopted much like referring
to a tissue as Kleenex). Competing companies also market 410a
systems under different names, all with a little twist on
the "on" portion of the name. 410a was designed
to prevent damage to the ozone layer by eliminating the chlorine
found in its chemical composition. 410a systems generally
utilize less electricity than regular systems but operate
at extremely high pressures as compared to their R-22 counterparts.
does AFUE stand for?
AFUE stands for Annual Fuel Utilization Efficiency. AFUE measures
the efficiency of a furnace by indicating the percentage of
the fuel (usually natural gas) that is converted into heat
used to warm your home. Government regulations require systems
to have 78% AFUE, but Nash Mechanical usually sells furnaces
with 80+ AFUE ratings. As natural gas prices continue to rise,
a higher AFUE rating will provide a greater return on investment
in a shorter period of time.
