Where Does Air for an Air Conditioner Come From?


Have you ever wondered where your air conditioner pulls the air that you then cool with it? By understanding how the air intake system works in an outdoor central.

Conditioning unit, people will be able maintain their equipment better and get better performance from it as well.

This article will go over the specifics of where do air conditioners pull air from. It also goes through how it affects your home’s comfort.

Importance of Outdoor Unit

A central air conditioning system is provided only in part by the outdoor unit, commonly referred to as the condensing unit. It is the big box outside.It is normally put either at the back or the side of your downpipe.

The outdoor unit includes a fan, which takes in air from the surrounding environment. This air is moved through the coils of an air conditioning machine, where it combines with refrigerant and the heat is removed from air.

Now-warmed air is carried out by pneumatic travel, and left lurking on the lower floor inside your house with cold water vapour.It all depends on how rapidly the fan in the outdoor unit pulls air into it and through its cooling mechanism, and indeed how great a volume of heat can be removed from the air.open-air unit.

The air handler indoor unit, while not only where the heat exchange is done in fact also serves as a little air conditioning subsystem that blows out cool breeze is inhaled into your ductwork at top speed.even the air supply ducts and registers to your rooms in throughout the house.

The indoor unit also contains a fan that sucks air from inside your house. This air is passed over an interior coil where the heat is removed, then cooler (and drier) air is blown through supply ducts and vents.Your home’s HVAC system includes return ducts that deliver warm indoor air back to the air handler where it is cooled and sent back into your house. This is the reason why your home cooling system can keep it cool all summer long.

Significance of Indoor Air Quality

External air often contains contamination such as pollen, dust, and even vehicle exhaust fumes, all of which then get into your house with its air system.

In order to maintain indoor air quality at a good level, most air conditioning systems are equipped with air filters that can screen out these contaminants before they enter the indoor unit.

Regular cleaning or changing of these filters is a necessary part of keeping your air conditioner system from recirculating poor quality air around your home.

Impact of Airflow Restrictions

The efficiency and effectiveness of your air conditioner’s cooling are very much related to the airflow through the system. Where there are any restrictions or blockages in–the air intake or exhaust for example this will reduce the amount of air that the unit can take in and process.

Common causes of airflow restrictions include:

  • Dirty air filters
  • A blocked outdoor unit
  • Leaks or blockages in the ductwork
  • Processes corrupted by undersized or improperly designed ductwork

Maintenance of Air Intake for Your Air Conditioner

It’s essential that its air intake components are kept in good working order. This means:

Make sure your air filter is checked for dirt and replaced periodically. Check the outdoor unit to make sure it’s not blocked or hidden by debris, or other obstructions like plants.

Examine the ductwork for air leaks and correct them promptly. Make sure it’s being used correctly and that the type of fuel used to power your heating or cooling system is suitable for your home’s climate.


By keeping a close eye on your air conditioner’s air intake, you can prolong the life expectancy of each system; always have indoor air quality greatly improved during the winter months, and get energy efficient cooling that is both reliable and affordable all summer long too.
