Do Air Conditioners Bring in Fresh Air from Outside?

Our daily lives have come to depend on air conditioning, especially during the sweltering summer months. By controlling the temperature and humidity levels inside buildings and homes, air conditioners create a comfortable living environment. Though the question of whether air conditioners actually bring in fresh air from outside or just circulate the air inside is frequently raised, this typically depends on the type of air conditioning unit in question. 

Types of Air Conditioning Systems

Essentially, there are two main types of air conditioning systems, namely: central air conditioning and window air conditioning.

Central Air Conditioning Systems: These are the most typical air conditioning units found in residential and commercial structures. They distribute cool air throughout the structure using a system of ducts. These systems don’t bring in fresh air from the outside and are made to circulate the air inside the structure.

Window Air Conditioning Systems: Due to their self-contained nature, ductwork is not needed. These devices often draw air in from the outside through a window or a hole in the wall. They do this to continuously produce fresh air by cooling the air and then releasing it back outside.

Which Air Conditioning System is Better?

There are pros and cons worth considering for both central air conditioners and window units. 

Central air conditioning systems utilize less energy to chill the air because of their design. The system would have to work harder and use more energy to bring in fresh air from outside, which would result in greater energy costs. However, bringing in outside air can impair indoor air quality by introducing toxins, allergies, and other pollutants into the structure.

Window air conditioners, however, don’t necessarily draw in fresh air from the outside. Certain units work similarly to central air conditioning systems and are designed to circulate the air inside. Before installing a window air conditioner, it’s crucial to check the manufacturer’s guide to determine if it draws in fresh air from the outside or not.

How your air conditioning system is installed will also affect whether or not it brings in fresh air. An outside air inlet, for instance, can be added to some central air conditioning systems. By modifying the system, fresh air from the outside can be introduced, enhancing the quality of the air within.

All in all, the effectiveness of an air conditioning system depends on the type of unit and how it is installed. Regular cleaning and maintenance of your air conditioner can also help to enhance indoor air quality and guarantee effective performance.
