If you want to get a
central air conditioner installed in your home, first make sure that
the unit you get is just the right size for your space. Make it too
big, and your AC will spending more energy than needed to cool a
room; get one that’s too small, and it will easily wear itself down
in trying to adequately cool a room nonstop.
AC Sizing Units
When measuring a space
for an AC, there are two concepts that you should always remember:
BTU and ton. BTUs, or British Thermal Units is the standard measure
of an air conditioner’s cooling capacity with respect to room
dimensions. Essentially, it is the amount of energy needed to raise
the temperature of one pound of water to one Fahrenheit. Other places
use ton, which is equal to 12,000 BTU, in place of this unit.
Basic Factors
The size of the room is
a key factors in selecting the size and capacity of your air
conditioner. There are other factors. The shape or geometry of the
space also affects how the cooled air travels and spreads throughout
the room. Similarly, the number of windows and openings in the walls,
the amount of insulation, and even the amount of heat produced by
interior lights are also contributing factors.
