How Cold Should the Air Be From My Window Air Conditioner


These are usually smaller units that are designed to cool a room or area inside the home. They are often situated in the window of rooms. They were originally built for those homes that did not have central air conditioning systems, and they can easily be attached to your home’s windows. They will require a window opening that is 10″ by 14″.

You will need to measure this if you live in an older home so you do not make any mistakes when installing it into your home. You would not want to purchase one only to find out it doesn’t fit! It comes with various features, depending on which model you choose. You must get one, even though they cost money, because they could help. Today I will discuss how cold the air should be from my window air conditioner.

A Guide to How Cold Should the Air Be From My Window Air Conditioner

The short answer to the question is that the air conditioner should be set to “ECONO” mode to keep the room comfortable and minimize energy costs. This mode will decrease the temperature into what is called “the chilling zone”, which is a range of cold temperatures between 64 and 75 degrees.

Anything lower than this could risk damaging your unit through humidity build-up or ice accumulation preventing proper operation. To help prevent damage to the unit, it’s better to set the temperature into the mid-sixties when cooling your home with your AC running on ECONO mode.

How To Unclog Our Window AC Unit or Condenser Coil

  • Go to your local hardware store and get a can of 3% Hydrogen Peroxide. The pros use this to unclog clogged coils in window air conditioning units, heat pumps, refrigerators, freezers, etc.
  • Spray about 10-12 squirts (usually equals one tablespoon) of 3% Hydrogen Peroxide onto our condenser coil fins (“c” value on the label shown below) from 5-6 ft away using a spray bottle with a good spray nozzle as this will give you more even coverage with less chance of over-spray which can damage other parts of the unit such as our compressor or outdoor fan.
  • Wait around 5 minutes for the peroxide to start fizzing and bubbling on the coil, which indicates that it is now at work neutralizing the clogged dirt from our coils fins using its acidic properties (Note: Proper ventilation is advised with a fan running during this process).
  • NOTE: If you are dealing with more than one AC unit, be sure to do the above steps for both sides of each AC unit if there are two units in your property or house.
  • Follow up with a light spray of Furnace Air Filter Cleaner if necessary after neutralizing any drainage residue left over after our coil cleaning procedure (this step will help prolong the life of our air conditioning, heat pump, refrigerator, freezer, etc. unit’s entire cooling system).

What are The Special Features of A Window Air Conditioner?

You can install a window air conditioner almost anywhere in your home. They work by extracting hot air from inside your home and blowing cool air into it, significantly reducing the temperature of the interior space. In fact, some can lower temperatures far more effectively than a whole-house central AC unit or larger stand-alone units installed in an attic or other room of your house.

In addition, window air conditioners have special features that make them especially efficient and convenient to use while still providing significant cooling power.

Why are Some Window Air Conditioners So Loud?

Window air conditioner units can vary widely in how much noise they produce, ranging from relatively quiet models to those that seem almost as noisy as a regular central air conditioning system. One of the most common causes of excessive noise from a portable AC unit is insufficient ventilation around the unit (either through lack of proper installation or an older design lacking a sufficient vent).

As a result, as the hot air inside the unit escapes, it cools, and pressure builds up inside the metal case surrounding the refrigerant coils. With no place for this pressure to escape except into your room, it makes you hear a banging or hissing sound while also causing potential damage to the compressor motor or other parts inside.

Precautions While Using a Window AC

  • Air conditioners are designed for rooms and not for outdoor use
  • To avoid damage, do not cover the grills of any air conditioner with newspapers, tablecloths, curtains, or other materials while it is in operation. 
  • When operating an air conditioner in a window position, always keep the screen in place or closed to prevent children from coming into contact with the unit.
  • To reduce energy consumption, especially when using your air conditioner to cool off only one room, try using ceiling fans, which help distribute cooled air evenly throughout the room and reduce energy costs without turning on your AC units.
