Air Conditioners - How to Cut Running Costs in Half
In today's world, most people have invested in one form of an
air conditioner or another. We have either window air
conditioners in our homes or central air conditioners. They keep
us cool in the extreme summer heat without fail; however, have
you ever set back and looked at the costs of running an air
conditioner? When compared to the common household fan the
amount of electricity required to run an air conditioner is
phenomenal.
When using an air conditioner there are many different factors
that can directly affect the cost of running it. These factors
include the geographical location of your home, where you live
and the amount of work the air conditioner has to do greatly
influence the cost. If you live in an area that has mild summers
and extremely cold winters, obviously your air conditioner will
not have to work as hard. However, if you live in an area, that
has warm winters and boiling summers the air conditioner will
have to work double time to maintain comfort.
The difference in weather conditions from year to year will
affect the costs as well. This is basically geared towards the
difference in costs per year. One summer might be cooler than
the next, which will lead to a greater bill.
The efficiency rating of your air conditioner plays an important
role in the amount of electricity used. Most all appliances in
today's world are rated, when you purchase an air conditioner it
will have a tag telling you the amount of electricity that
appliance uses. Look for air conditioners that use minimal
electricity, which will save you money each year. If you have a
model that is 10 years or older, it is definitely time to
consider a new one.
Another important factor is the size of the air conditioner
versus the house-cooling load. All air conditioners come in
different sizes, and each will state the amount of space it is
designed to cool. For example, an apartment could do with just
one or two window air conditioners, while a three-bedroom house
could not. Closely consider the amount of space you need to cool
when considering an air conditioner. While larger air
conditioners will cost more money, it will typically save you
money in the long run on usage.
The setting on your thermostat greatly effects the cost. A
higher setting will result in the air conditioner running less,
while lowering the setting will cause it to run more often. One
electric company suggests keeping the thermostat above 78
degrees. This can save you 10 to 20% on cooling costs.
Finally, the local cost of electricity influences the general
cost of running your air conditioner. This is something you have
no control over, however, you can control your own cost by
saving energy.
Here is a general look at the difference of running an air
conditioner vs. running a Ceiling or oscillating fan, at medium
speed.
Running a central air conditioner that is three ton (and of
average efficiency) for 8 hours per day for 15 days per month,
with the average rate per kWh (kilowatt per hour) being 0.17,
the average cost per month for the air conditioner alone will be
$97.92. Amazing isn't it? This does not even include washer,
dryer, lights, refrigerator, or stove, only the air conditioner.
On the other hand, running a ceiling fan or oscillating fan at
medium speed, for 8 hours per day, for a full 30 days, at an
average rate per kWh of 0.035 is only $1.43. With this
comparison you could run 68
