Central Air Conditioning
An air conditioner is responsible for keeping your home cool, but do you understand how it works? Notice there is no ducting travelling from your air conditioner outside, to inside your home. So where exactly does the cool air come from?
How It Works
Home air conditioning happens by removing heat energy from your home…not by blowing cold air into it. Air is pulled from the home via the fan motor in your furnace (or air handler). The warm air is then forced through the indoor coil, which contains chilled refrigerant. The refrigerant absorbs heat energy out of the air (which cools it). The heated refrigerant is pumped out to the air conditioner where the refrigerant is compressed. Compressing the refrigerant releases the heat energy into the outside air!
Air Conditioning Efficiency
The efficiency of an air conditioner is measured by a Seasonal Energy Efficiency Rating (SEER) which indicates how much power is required to cool a certain space. However, the efficiency of your air conditioner isn’t the only factor. The efficiency of the fan motor, ducting and the quality of the installation all weigh in to dictate overall cooling efficiency.
