Does Central Air Pull Air from Outside?
Central air conditioning keeps your home comfortable during hot summer months, but you might be wondering – where does all that cool air come from? Does your system pull in fresh, outside air and cool it down, or does it recirculate the air that’s already inside?
Short answer: your central air conditioner does not bring fresh air from outside your home. It recirculates the air that’s already inside your home and cools it down. Here’s an inside look at how central air conditioners work.
-
A fan pulls warm air from your home into your unit.
-
A filter in your air conditioning unit filters out dust, pet dander, and other allergens from the air in your home.
-
The air travels over a cold evaporator coil, which absorbs heat from the air. A refrigerant circulating through the coil aids in the cooling process.
-
As the air cools down, moisture is lost, and it condenses on the coil and drains out of your system.
-
The cooled air is then distributed through vents located throughout your home.
-
Now that the refrigerant is warmed up from absorbing the warm air indoors, it travels to your condenser coil. A fan blows air over the condenser coil, and releases the heat back outside.
