Can Air Conditioners Pull in Fresh Air from Outside?

No, an air conditioner does not bring fresh air from outside into your home. Even if part of your system is located outside, like in a split system, it doesn’t utilize outside air. The main function of an air conditioner is to expel unwanted heat from your indoor air, not to cool it by using outside air.

Removing Unwanted Humidity

To expel heat from your home, the Air Conditioners uses a heat pump to move it outside. This heat pump can operate in both directions: it moves heat outside during the summer and brings it inside during the winter. The compressor extracts warm air from your home using a refrigerant, which facilitates the heat exchange process to cool your home.

Keeping the Air Cool

Keeping the Air Cool

This cooling process, known as the refrigeration cycle, involves the heat exchanger undergoing changes in state, pressure, and temperature to remove heat from your home. The cycle includes four stages: the refrigerant absorbs heat and becomes hot, the heat is transferred outside, the refrigerant cools down, and the cooled refrigerant is then circulated throughout your home.

Air Changes

As the refrigerant re-enters your home, it passes through a valve into the evaporator, which is kept at low pressure to allow rapid expansion and cooling. A fan blows air over this cooled refrigerant, distributing it through your home’s ductwork. Once the refrigerant has cooled, it returns to the condenser, and the cycle begins again.

Do I Need Additional Ventilation?

In some cases, additional ventilation may be necessary to properly cool your home. This can help reduce cooling needs, improve indoor air quality, and lower utility bills. The required ventilation depends on factors like your comfort needs, family health, the age of your home, and its construction. It is advisable to consult an HVAC professional to determine your ventilation needs.
