How Do Window Air Conditioners Work?

A window air conditioner is a single room cooling unit specifically designed to fit inside a window opening. It operates by pulling the air from outside the house and pumping it inside via a set of onboard fans and a cooling apparatus.

The cooling apparatus works by removing the heat from the air. This is done through a process that utilizes a compressor to pressurize and heat the liquid cooling chemicals inside your AC unit. After the chemicals are heated, a condenser dissipates the heat as it travels up towards an expansion valve.

Window Air Conditioner Diagram

And that’s when things start to get cool! The chemicals are now icy cold, and they flow down into an evaporator coil positioned right in front of the main AC fan. As the fan circulates the air from outside, the air is cooled by the evaporator coil.

The fan pushes the air out into your room, and voila! Your room starts to cool.

Depending on your AC settings, this goes on until an optimum room temperature has been achieved.

Types of Window Air Conditioners

Most window air conditioners allow you to set a specific temperature on the unit’s display. Once the air in the room reaches a certain degree, the AC unit actively maintains it by reading the room temperature and adjusting the cooling (or heating) output appropriately.

In general, window AC units contain up to 3 main temperature options depending on the unit you buy.

Window Air Conditioner Modes

  • Cooling. This pulls the air from outside and cools it down before circulating it throughout the room.
  • Fan mode. This simply draws the air in from outside and releases in into the room, while removing any stale air.
  • Heating. This pulls the air in and heats it before hot air dissipates throughout the room. This is great in the cooler months.

Power

In terms of power, window air conditioning units are measured by BTU.

BTU, or British Thermal Unit, is the amount of heat required to raise a single pound of water by a single degree.

In plain English, this simply means that your air conditioner BTU rating is crucial for measuring how much heat the AC unit can remove from the room. Generally speaking, the higher BTU units are more powerful and effective.

You must choose the appropriate window air conditioner for the size of the room you’re installing it. As an overall guide, you’ll want to stick to the following measurements:

  • 200 sq/ft: 6000 recommended BTU
  • 400 sq/ft: 9000 recommended BTU
  • 600 sq/ft: 13000 recommended BTU
  • 800 sq/ft: 15000 recommended BTU
  • 1000 sq/ft: 18000 recommended BTU

After 1000 square feet, you’ll want to increase your BTU by a few thousand units for each 200 sq/ft jump.

How to Pick a Window Air Conditioner For Your Room

There are many different styles of window AC units! Some units simply draw air from the outside and pump it in. Others cool the air down, and some even heat things up!

To make matters more difficult, there are a ton of different manufacturers out there. Frigidaire, Kenmore, LG, and more are all big players on the scene.

Regardless of the manufacturer, make sure to check that the actual style of the unit fits with the room. There are many bulky units that work great for pumping out tons of cool air, but they don’t look very good. On the flip side, some of the slimmer, more streamlined models simply can’t maintain the temperature you need.

Features

Many units also have extra little perks and features that you’ll want to take into account as you’re browsing. These little bonuses can make or break your purchase, and you always want to get the best bang for your buck!

The great thing about window air conditioners is that they’re super easy to install. With just a handful of tools and an hour of work, you’ll be ready to keep cool anytime!
