                                       TIME  FOR A
                                       CHANGE?
How do you know if it's time to replace your old cooling and heating
equipment or improve the performance of your overall system? It may
be time to call a professional contractor to help you make a change if:
> Your heat pump or air conditioner is
more than 10 years old. Consider replacing
with ENERGY STAR qualified equipment
that      ' least 20 p       ess energy
than new            'Is.

> Your furnace or boiler is more than
15 years old. Consi      'lacing with
    NERGY STAR qualified f
would be 15 percent more efficient than
a convLMitmnal furnace. Or, if you have
boiler, consider n      i with an ENERGY
STAR qualified 01

> Your equipment needs frequent repairs
and your energy bills are going up. Your
cooling and heating equipment may have
become less efficient

> Some of your rooms are too hot or cold.
Improper equipment operation, duct prob-
lems or inadequate insulation could he
   cause.

> No one is home for long periods of the
day and you don't have a programmable
thermostat. Install an ENERGY STAR
qualified programmable thermostat or
have a professional contractor install one
   < instruct you on its use to start saving
energy and money while you're away or
even sleeping.
> Your home has humidity problems.
Poor equipment operation, madequ
equipment, and leaky ductwork can
cause the air to be too dry in the
winter or too humid in the summer.

> Your home has excessive dust. Leaky
ducts can pull particles ami  air in from
attics, crawlspaces and basements and
distribute them through the house. Having
your ducts sealed may I;

> Your cooling system is noisy. You
could have an undorsi/od duct sysi
or a problem with the indoor coil of your
cooling equipment.

> Your score on the ENERGY STAR Home
Energy Yardstick is below five. That
means you're using more energy at home
than most Americans and probably pay-
ing more than you need to on energy bills.

                   MAINTENANCE
     Maintain your equipment to prevent future problems and unwanted costs.
     Keep your cooling and heating systems at peak performance by having a
     contractor do annual pre-season check-ups. Contractors get busy once
     summer and winter come, so it's best to check the cooling system in the
     spring and the heating system in the fall. To remember, you might plan the
     check-ups around the time changes in the spring and fall.
     COOLING & HEATING
     MAINTENANCE CHECKLIST
     Your contractor should complete the following each spring and fall:
     > Check thermostat settings to
     ensure the cooling and heating
     system turns on and off at the
     right temperatures.

     > Tighten all electrical connections
     and measure voltage and current on
     motors. Faulty electrical connections
     can cause unsafe operation of your
     system and reduce the life of major
     components.

     > Lubricate all moving parts. Parts
     that lack lubrication cause friction
     in motors and increase the amount
     of electricity you use.
> Check and inspect the condensate drain
in your central air conditioner, furnace
and/or heat pump (when in cooling mode),
If plugged, the drain can cause water
damage in the house, affect indoor
humidity levels, and breed bacteria.

> Check controls of the system to ensure
proper and safe operation. Check the
starting cycle of the equipment to assure
the system starts, operates, and  shuts
off properly.

> Inspect, clean, or change air filters once
a month in your central air conditioner,
furnace, and/or heat pump. Your contractor
can show you how to do this yourself.
Depending on your system, your  filter may
be found in the duct system versus the
cooling and heating equipment itself.
A dirty filter causes energy costs to be
greater than they should be and  can
damage your equipment, leading to
early failures.

The following  checklists outline additional steps
your contractor should follow when servicing either
your cooling or heating system;
CHECKLIST
CHECKLIST
> Clean evaporator and condenser air
conditioning coils before warm weather
starts. Dirty coils reduce the system's
ability to cool your home and cause the
system to run longer, costing you more
energy dollars and decreasing the life
of the equipment

> Check your central air conditioner's
refrigerant pressures and adjust charge
if necessary. Too much or too little
refrigerant charge can damage the
compressor, reducing the life of your
equipment and increasing costs.

> Clean and adjust blower components
to provide proper system airflow for
greater comfort levels. Proper airflow
over the coils to improve equipment
efficiency and reliability. Airflow problems
   reduced your system's efficiency
by up to 15 percent.
> Check ail gas (or oil) connections,
gas pressure, burner combustion
and heat exchanger. Improperly
operating gas (or oil) connections
are a fire; hazard and can contribute
to health problems. A dirty burner
or cracked heat exchanger causes
improper burner operation. Either
can cau        npment to operate
less safely and efficiently.
                                                                      p.07

 ENERGY STAR
COOLING  &
HEATING EQUIPMENT
REPLACE WITH  EQUIPMENT THAT
HAS EARNED THE ENERGY  STAR.
               PROGRAMMABLE
               THERMOSTATS
               Using a programmable thermostat to consistently control your
               home's temperature <     - e you about $100 every year in energy
               costs when used properly. Use the four pre-set temperature week-
               day and weekend settings for your home depending on whether
               you're at work, at home, or in bed at night.

               Programmable thermostats that have earned the ENERGY STAR
               provide you with more flexibility than standard models and unlike
               older mechanical thermostats, contain no mercury. Just remember
               to install your thermostat away from naturally cool or hot spots so
               it can accurately read the temperature in the house.
               BOILERS
               A boiler heats your home by burning gas or fuel oil to heat water or
               steam that circulates through radiators, baseboards, or radiant floor
               systems. Boilers do not use a duct system. A properly sized and
               installed ENERGY STAR qualified boiler uses about 6 percent less
               energy than a standard new boiler. Boilers that have earned the
               ENERGY STAR have higher AFUE ratings. AFUE, the Annual Fuel
               Utilization Efficiency,  measures the heating efficiency of boilers.

               How much energy you save will vary based on your use and climate,
               with colder regions likely saving more. Features that improve boiler
               efficiency include electronic ignition, which eliminates the need
               to have the pilot light burning all the time, and technologies that
               extract more heat from the same amount of fuel.

     FURNACES

     Furnaces are the most commonly used residential heating system in
     the United States, running most often on gas, but sometimes on fuel oil
     or electricity, and deliver their heat through a duct system. One in four
     furnaces in US homes today is more than 20 years old. ENERGY STAR
     qualified furnaces use advanced technology to deliver 15 percent
     higher efficiency than standard new furnaces available today.
HEAT  PUMPS

Electric Air-Source Heat Pumps (ASHPs): Often used in moderate
climates, ASHPs use the difference between outdoor and indoor air
temperatures to cool and heat your home. ASHPs remove excess heat
from indoor air and release it outdoors. ENERGY STAR  qualified ASHPs
use about 20 percent less energy than conventional models. They also
come with  higher HSPF ratings. HSPF, the Heating Seasonal Performance
Factor, measures the heating efficiency of heat pumps

Geotherrnal Heat Pumps (GHPs): By using stable temperature
conditions  in the ground, GHPs cool and heat your home. In addition
to providing much lower energy bills with 30 percent higher efficiency
than standard new models, ENERGY STAR qualified GHPs are quieter
and include water-heating capabilities. Although initially expensive,
they quickly pay back the homeowner with significant  cost savings.
GHPs are most often installed in new homes and require a duct system.
Find out if a GHP might be right for your home.
     CENTRAL AIR
     CONDITIONERS

     ENERGY STAR qualified central air conditioner are 25 percent
     more energy-efficient than today's standard equipment. Central
     air conditioners that have earned the ENERGY STAR have a higher
     SEER than standard models, SEER, the Seasonal Energy Efficiency
     Ratio, measures energy efficiency The higher the SEER, the greater
     the level of efficiency. Since sizing and proper installation of a
     central air conditioning system are critical to  energy efficiency
     and home comfort, it is important to hire a qualified technician.

                 SIZING  & INSTALLATION
                 When purchasing cooling and heating products, pay close
                 attention to several things: getting the right-sized equipment
                 for your home, getting a quality installation, getting the right
                 professional to work with you, and asking the right questions.
MAKE SURE YOUR UNIT IS PROPERLY SIZED.
WHEN IT COMES TO COOLING AND HEATING EQUIPMENT,
BIGGER ISNT ALWAYS BETTER.

                 With cooling and heating equipment, a larger-sized product is
                 intended to meet the needs of a larger area. However, if the
                 equipment is too large for your home, you will experience
                 increased costs and less comfort. Over-sized equipment will
                 operate in short run times or cycles, not allowing the unit to
                 reach efficient operation or deliver even temperatures
                 throughout the home.

                 Don't assume that the size of your new system will be the same
                 as your otd equipment. Changes, such as additions or insulation
                 improvements, may have been made to the house since the
                 original equipment was installed; or, the equipment may have
                 been too  large from the start. Your contractor can calculate
                 the right size for your cooling and heating equipment by using
                 Manual J, or an equivalent calculation tool. Ask for it.

    TO  PURCHASE AND HAVE NEW
    EQUIPMENT  INSTALLED, YOU WILL
    NEED  TO  HIRE A CONTRACTOR,

    The following sections will help you find the right contractor, get quality
    and value from the contractor and your new equipment, and get a signed
    agreement on the work to be done. Many of the following recommendations
    also apply if you choose to work with a contractor on home improvements
    such as home sealing or duct work.

               1. HOW DO YOU FIND
                 THE RIGHT CONTRACTOR?
                 A reputable contractor should:
                 > Perform an on-site inspection of the job you want done and
                 provide a detailed bid in a timely manner.

                 contractor in your area, recognized by your local municipality; and
                 (B) licensed and insured to repair or install cooling and heating
                 equipment (many states require this).

                 > Be able to provide their certification for refrigerant handling,
                 required since 1992.

                 > Have several years in business in your community.

                 > Provide examples of other quality installation work, with names
                 of customers that you can contact.

                 > Ask whether a contractor's service technicians are certified by
                 North American Technician Excellence (NATE) to professionally
                 install and service cooling and heating systems. For a list of
                 contractors that employ NATE-certified technicians in your

ENERGY STAR
HOME SEALING
RECOMMENDATIONS
1) Seal air leaks to reduce drafts and get the full performance out of insulation.
The biggest leaks are usually hidden in the attic and the basement. Caulk and
spray foam products can seal many of these holes. Always work to reduce air
leaks before installing insulation.

2) Add insulation to keep your home comfortable and energy-efficient even during
periods of extreme temperatures. The most effective place to add insulation is
usually in the attic. The U.S. Department of Energy offers recommended insulation
levels for each part of the house in different climates. Visit www.energystar.gov
and click on Home Improvement to see home insulating recommendations.

3) Choose ENERGY STAR qualified windows when replacing  or adding windows
to a home. Be sure to select windows that are rated for your climate zone.
Whether you seal your home yourself or have
a contractor seal and insulate your home, it
is important to have a professional perform a
Combustion Safety Test afterward to be sure
all your gas or oil burning appliances are
working properly.

         Your new or existing cooling and heating equipment is only as good as
         the system that carries its cooled or heated air. Central air conditioners,
         heat pumps and forced air furnaces rely on a system of ducts to circulate
         air throughout your home. To maintain comfort and good indoor air quality,
         it is important to have the proper balance between the air being supplied
         to each room and the air returning to your cooling and heating equipment.
         Leaky ducts can cause an unbalanced system that wastes energy. Sealing
         your ducts improves your system's ability to consistently cool and heat
         every room in your home,

DUCT SEALING INCREASES THE EFFICIENCY OF
YOUR COOLING AND HEATING SYSTEM, POTENTIALLY
SAVING UP TO $140 EVERY YEAR.

         Whether you're having new equipment installed or working to improve the
         performance of your existing cooling and heating system, you should have
         your duct system checked.

         To improve your ducts, make sure to have your contractor:
         > Identify any leaks with
         diagnostic equipment

         > Seal your ducts with mastic,
         metal-backed tape, or aerosol
         sealant Duct tape should not be
         used; it can not withstand high
         temperatures and will not last.

         > Test airflow after ducts
         are sealed.
> Insulate your ducts where it counts
to keep the air at its desired temperature
as it moves through the system. The
contractor should use duct insulation
material rated at R-6 to insulate ducts
located in unconditioned spaces such
as the attic.

> Conduct a combustion safety test
after ducts are sealed to be sure all
gas or oil-burning appliances are
working properly.
