General Cooling Tips
Of course, the best way to reduce your air conditioning bills is to
reduce heat in your home, especially during summer months. The tips
below can help reduce the workload on your air conditioning solution:
* Set the temperature a little higher. Most people can be
comfortable with a setting of 78-80 degrees Fahrenheit, plus you'll
save 6 percent to 8 percent of your cooling costs for each degree
* When you leave home, turn off the air conditioning or set the
thermostat up a few degrees.
* Be sure your filters are clean. They should be checked monthly.
(Remember to check filters that may be in a unit located in the
attic.) Coils of an outdoor unit should be free of debris and not
blocked by plants, shrubs, etc. Be sure the return air grill inside
your house is not blocked by furniture or other items. (If you have
more than one return, check them all.) A return needs a free flow of
air for the air conditioning to operate most efficiently.
* Keep doors and windows closed when air conditioning is on. Turn
off kitchen or bathroom exhaust fans when your air conditioning is
* Caulk and weather-strip leaky windows and doors.
* Use a ceiling fan or portable fan to supplement your air
conditioning. A fan can make you feel three to four degrees cooler
(and only costs a half-cent per hour to operate) so you can set your
thermostat a few degrees higher and save on cooling costs. Use in
occupied rooms since fans cool people, not rooms. As a safety
precaution, turn off ceiling fans when you leave your home.
* For central air conditioning systems, keep the fan switch on
your thermostat in the "auto" position when cooling. This gives you
better cooling and humidity control. Having the fan switch "on"
continuously could cost $15 extra a month on your electric bill.
* Use shades or drapes to block the hot sun from heating up your
home. Use awnings, trees and shrubs to shade your home.
* Use your microwave or countertop appliances for cooking instead
of the oven or stove.
* If you suspect your air conditioning system is not cooling
properly, have it checked promptly. A unit that is having operational
problems can cause extremely high bills.
* If your air conditioning equipment is older and less efficient,
compensate by being extra careful about temperature settings, hours of
operation and filter condition.
* Make sure your home is properly insulated. In existing homes,
wall insulation may be too expensive to install, so concentrate on
attic and floor insulation.
General Heating Tips
* Keep your thermostat at the lowest comfortable temperature ? 68
to 70 degrees is recommended. Every degree above 70 costs an
additional 3 percent to 5 percent. (Example: Keeping your home at 75
degrees could cost up to 28 percent more on the heating portion of
your bill than keeping it at 70.)
* During winter months, Progress Energy recommends setting the
temperature at 70 degrees Fahrenheit during the day and 60 to 65
degrees Fahrenheit at night.
* By setting your thermostat back 10 degrees at night (8-10
hours), you'll save 10 percent to 20 percent in heating costs. The
lowered thermostat setting saves energy dollars by reducing the length
of time the heating system operates throughout the night.
* Lower your thermostat at night or when you leave the house.
* Keep doors and windows closed when heat is on.
* If you have a fireplace and aren't using it, make sure the flue
is closed. Consider glass doors to help prevent heat loss when your
heating system is on.
* Using a portable heater for "spot" heating lets you lower the
temperature in the rest of the house. However, using it too much can
be very costly! One 1500-watt resistance heater operating 24 hours a
day for a month would cost more than $80.
* If you have a heat pump, adjust your thermostat in small
increments to avoid the operation of the supplemental heat strip in
your system. Energy consumption is much higher when the heat strip is
in use. A steady setting on your heat pump thermostat produces
constant comfort and minimizes the use of the less efficient
resistance heat strip.
* Don't block the outside unit. Never stack anything against the
heat pump or drape anything over it.
* Hose down the outside unit from time to time to remove dust,
dirt, lint, leaves and grass clippings.
* Be sure the filters in your heating system are clean. Dirty
filters will increase heating costs.
* Caulk and weather-strip any leaky windows and doors.
* Open drapes and shades on the sunny side of your house to help
warm the home during the day. Close drapes and shades at night to cut
* If the indoor unit seems to have excess water around it, check
the condensate drain and pan for blockage.
* Make sure drapes and furniture are not blocking air registers or
* Keep the fan on your central heating unit on "auto" position.
Leaving the fan on "on" can add $15 a month to your heating costs.
* Don't close off more than 10 percent of the unused rooms in your
home. Your heap pump works best with free airflow throughout the house.~*~*~*~*~*~*~*~*~*~*~*~*~*~*~

I replace my filters for my two heat pumps (I live in a 2 story house) every month.
I also replaced a lot of light bulbs with CFLs.
I've noticed my elecric bill went down after I switched light bulbs.

We bought some window film for our window's this summer and it really made a difference in how cool the rooms were.

we use cieling fans all year long and we put them on reverse in the winter so the hot air goes down and not stay by the cieling. (hope that makes sense)
