Do Air Conditioners Pull In Outside Air To Work?



While air conditioners do have monumental benefits that span a wide range of services, we can’t take credit for a service that it does not provide. It is true though, that air conditioners and many other HVAC products are getting more and more advanced as new technology rolls out per year. 

But, as of right now, air conditioners do not pull in air from outdoors through the vents into the specified room.

For some people, this can be seen as a positive discovery due to the worries of days with heavy pollutants in the air. You may be worried because the lack of filtration that occurs between the duct systems will hypothetically result in polluted air filling your homes. So for the people who were worried about that, don’t be because it’s not happening. 

That’s not to say your homes are getting polluted air from a different source, which is why we recommend calling an HVAC technician immediately if you feel as if you’re breathing in polluted air. 

Now that we understand the realities of what services your air conditioner can provide you. Let’s get into what exactly is going on when an HVAC technician installs an air conditioning unit in your home!

True power of an Air Conditioning Unit

What really happens when you get your AC unit installed? 

Instead of pulling fresh outside air into the homes of the targeted zones, your air conditioner actually pulls air OUT of your home and into the exterior area surrounding your home. By doing so, it’s doing the opposite of what we were discussing in the previous section! 

The outside air is brought into the intake container within your air conditioning system, and within the ductwork systems, it actually pushes the unwanted heat out while keeping the temperature of the room nice and cool. Pretty cool, right? 

How does it do this? 

Thanks to heat pumps! These amazing pumps are able to allocate heat in either direction, (both internally and externally) depending on if you’re dealing with the hot summer nights during California’s crazy heat waves or the coldest of winter nights in the eastern states! 

But how does the heat pump manage to capture and release the heat itself? 

With air conditioning pumps! That’s right, more pumps. The air conditioner pump, better known as the “compressor”, pulls the warm air out of your home, and with the help of a special coolant known as “refrigerant,” it offers a means of transport for the heat to exchange! 

This cycle of back-and-forth heat exchange is known as the “refrigeration cycle” and is a complex process all on its own. Don’t worry, we won’t get into it right now but if you do want to learn more about it we recommend doing some of your own research into this process as it could really help get into some cost-effective solutions to your unit’s problems. 

Now that you have a basic understanding of the processes that go within an air conditioning unit, let’s list out and explain the necessary gears and parts to the HVAC unit itself! 

All parts and gears inside an AC unit 

Here is a list of the parts within an air conditioning unit that we already covered in the previous sections: 

  • Heat Pump
  • Compressor
  • Refrigerant

This is a list of the parts inside an air conditioning unit that has not been covered yet: 

  • Condenser Coil
  • Expansion Valve
  • Air Filter
  • Evaporator Coil
  • Blower
  • Compressor
  • Fan
  • Thermostat

There is a lot that goes into the amazing processes that exist inside an AC unit, and some equipment has extra parts and gears that create a type of specialty within it.

Importance of Maintenance

With so many different gears/parts with completely different functions, it makes total sense that something that works 24/7 (for some people) would need some type of maintenance. And that maintenance is vital to its health and purity. 

This post managed to just scratch the surface of everything that occurs inside an AC unit, and we haven’t even discussed different types of units and property styles. And because of that, having a membership with an HVAC company is a crucial step in maintaining the health of your AC unit.
