A broken air conditioner is no one's favorite! Your window AC unit must work properly when the temperature outside rises. This article will help you answer the question, “Why Is My Window AC not working? ”

Here are five reasons why your window air conditioner isn't cooling

Listed below are the top reasons why your window AC unit may not be pumping out cold air. They are arranged from do-it-yourself fixes to issues you may need to call a professional for. In addition, we discuss an AC problem that may indicate it's time for a replacement.

The window air conditioner is in the wrong mode

One simple reason could be causing your window air conditioner not to cool. There is a possibility that it is not in Cool mode. There are several modes on window air conditioners, each of which serves a different purpose. There is some variation in which modes your window AC might have since not all window air conditioners are built the same way. Almost all window air conditioners have three modes: Cool Mode, Fan Mode, and Dry Mode.

The following is a brief explanation of what each mode does. Make the most of your window air conditioner investment by knowing your modes!

When your AC unit is in Cool Mode, it will remove heat from the room until it reaches the temperature set on the thermostat. It also dehumidifies the air, making it more comfortable, less "muggy." Once it reaches your desired room temperature, it will maintain it until you change the mode or adjust the thermostat.

The first thing you should check if your Window AC not working is this. Is your window AC set to Cool Mode? Check how things change if you put it in Cool Mode. You will have to keep hunting for the problem if it is still having trouble cooling your space despite being in Cool Mode.

The fan mode

In Fan Mode, your window AC functions as a simple household fan. By using the fan mode, the unit does not blow cold air, but circulates the existing air to create a good air flow. For a fresh spring day, when the outside air temperature is ideal, and you just want to circulate more air, this mode is ideal.

A mode of dryness

This mode is available on most newer window air conditioners. Another name for it is Dehumidifier Mode, and, as you might have guessed, it dries out the air! When your window AC unit is in Dry Mode, it is only removing moisture from the air - it is not cooling it. During a cool, humid day, this mode is ideal for drying things out, not necessarily cooling your home.

Replace your current window air conditioner when it's time (need)

In comparison to the cost of a new air conditioner, window air conditioners are expensive to repair. For just diagnosing the problem, most repair shops charge $50 to $75. There are also parts costs to consider. In many cases, a window air conditioner costs between $100 and $225. 

Our general response to the question of when to replace your current window AC is this: The older it is, the less you should spend on repairs. It makes sense to spend $100 or $150 on a room AC that is less than 5 years old. In our opinion, spending that much on something more than 8 years old is a waste of money. Depending on your budget and circumstances, you can choose between the two. A cost-effective solution would be to repair the unit rather than replace it if you live in an apartment but plan to move into a house in a few years - probably one with central air conditioning.
