When considering purchasing
a new Air Conditioner for your home, you should know
that today's best air conditioners use 30% to 50% less
energy to produce the same amount of cooling as air
conditioners from the mid 1970s. Even if your air
conditioner is only 10 years old, you may be able to
save up to 20% or 40% of your cooling energy costs by
replacing it with a newer, and more efficient model.
An air conditioner's
efficiency, performance, durability, and initial cost
depend on matching its size to the following factors:
1. The size of your home
and the number of windows it has;
2. The amount of shade on your home's windows, walls,
and roof;
3. How much insulation is in the ceilings and walls of
your home;
4. The amount of air that leaks into your home from
outside;
5. The amount of heat the appliances and occupants in
your home generate.
Know that a larger air
conditioner will not provide the best cooling. Buying an
oversized air conditioner will only serve the following
consequences: It costs more to buy a larger air
conditioner. The larger-than-necessary air conditioner
will cycle on and off more frequently, which will reduce
its efficiency. Frequent cycling makes indoor
temperatures change more and results in a less than
comfortable environment. Frequent cycling also reduces
moisture removal. In humid climates, removing moisture
is critical for comfort. This cycling also wears out the
electrical parts and compressor more rapidly. A larger
air conditioner will use more electricity and create
added demands on electrical generation and delivery
systems. |
