heating & cooling systems
& cooling your home accounts for about 44 percent of
your utility bill. It uses more energy than any other
system in your home. Reducing energy use for heating is
the one best way to reduce your home's contribution to
global environmental problems.
residential energy use represents 20 percent of all U.S.
energy use & nearly half of all energy used in the
home is for heating & cooling, a primary focus of the
ENERGY STAR® Labeling Program is home heating &
cooling equipment. Consumers spend 6 to 12 percent of
their gross incomes paying for home fuel & utility
costs. By purchasing energy-efficient heating &
cooling equipment, consumers can reduce energy use, save
money & help the environment.
& cooling equipment comes w/ two price tags: the cost
of purchasing the equipment & the cost to run it.
Although ENERGY STAR® heating & cooling systems
often cost more to buy, they can cost much less to run
because they use less energy. The Environmental
Protection Agency (EPA) estimates that when properly
sized, installed & maintained, ENERGY STAR labeled
heating & cooling products can save consumers 10 to
40 percent on heating & cooling costs.
STAR® is the symbol for energy efficiency.
STAR labeled products use less energy than other
products, save you money on utility bills & help
protect the environment. Look for the ENERGY STAR®
label on household appliances, home electronics,
office equipment, heating & cooling equipment,
windows, residential light fixtures & other
STAR® is a voluntary partnership between the U.S.
Department of Energy, the U.S. Environmental
Protection Agency, product manufacturers, local
utilities & retailers. Partners help promote
efficient products by labeling w/ the ENERGY STAR logo
& educating consumers about the benefits of energy
efficiency. By choosing ENERGY STAR labeled products,
you'll keep your utility bills down & help the
environment at the same time.
Guide labels are on all new room air conditioners,
central air conditioners, heat pumps & furnaces.
These labels are bright yellow w/ black lettering.
labels for room air conditioners, central air
conditioners, heat pumps & furnaces provide the range
of energy efficiency ratings for these products (EER,
SEER, HSPF & SEER & AFUE, respectively). Labels
on the most efficient models will show "This Model's
Efficiency" at or near the right-hand end of the range,
close to the words "Most Efficient."
furnaces now carry Energy Guide labels showing their
Annual Fuel Utilization Efficiency (AFUE). Energy Guide
labels on heating & cooling equipment refer customers
to manufacturers' fact sheets available from the seller
or installer. These fact sheets give further information
about the efficiency & operating costs of the
equipment under consideration.
even w/ an energy efficient system w/in your home you
will have a much greater impact on your energy costs if
you take a whole-house approach. By combining proper
equipment maintenance & upgrades w/ appropriate
insulation, weatherization & thermostat settings, you
can cut your energy bills & your pollution output in
saving tips when heating & cooling the
your thermostat as low as is comfortable in the winter
& as high as is comfortable in the summer.
warm-air registers & baseboard heaters as needed;
make sure they're not blocked by furniture, carpeting,
kitchen, bath & other ventilating fans wisely; in
just 1 hour, these fans can pull out a house full of
warmed or cooled air. Turn fans off as soon as they
have done the job.
the heating season, keep the draperies & shades on
your south-facing windows open during the day to let
sunlight enter your home & closed at night to
reduce the chill you may feel from cold windows.
the cooling season, keep the window coverings closed
during the day to prevent solar gain.
not turn the heat off in unoccupied rooms if it
adversely affects the rest of your system. For
example, if you heat your house w/ a heat pump,
closing the vents could harm the heat pump.
a programmable thermostat to control your temperature
& replace filters once a month.
ducts for air leaks.
set your thermostat at a colder setting than normal
when you turn on your air conditioner. It will not
cool your home any faster & could result in
excessive cooling & therefore, unnecessary
place lamps or TV sets near your air conditioning
thermostat. The thermostat senses heat from these
appliances, which can cause the air conditioner to run
longer than necessary.
your thermostat on 78° F or higher. Each degree
setting below 78° F will increase energy
consumption by approximately 8 percent. The less
difference between the indoor & outdoor
temperatures, the lower your overall cooling bill will
not use a dehumidifier at the same time your air
conditioner is operating because it will increase the
cooling load & force the air conditioner to work
