When the temperature outside begins to rise, many people seek the cool
comfort of indoor air conditioning. To some people an air conditioner is purely
a luxury but to others it's simply a necessity. This guide will discuss the
important issues that are relevant when you are considering getting an air
conditioner in your home.
Technically speaking, a split-system air conditioner
splits the hot side from the cold side of the system. Instead of having the
whole mechanism in the same place like the window unit, the split system has the
condensing unit outside.
BTU guidelines (capacity)
BTU (British Thermal Units) measures the cooling capacity of the air
conditioner. The higher the number, the more cooling power the air conditioner
has.
A room of 800 square feet will need a 12,000 BTU unit (depending on home
isolation). Bigger rooms such as 1500 square feet might need up to 18,000 BTU's to cool the
room properly.
EER OR SEER guidelines (efficiency)
EER (Energy Efficiency Rating) EER (energy efficiency rating) is another
important parameter required to classify air conditioners. The EER number tells
you how efficient the air conditioner converts the electrical energy into cool
air. For example, if a
10,000-BTU air conditioner consumes 1,000 Watts, its EER is 10 (10,000 BTU/1,000
Watts). So the higher the EER values are the cheaper the unit will be in power
consumption.
