Why Is My Brand New Window AC Not Cooling

These are the most common reasons why your window air conditioner isn’t blowing chilly air as it should. They’re organized from the simplest do-it-yourself remedies to the types of problems that require professional help. We also go through an air conditioning problem that could mean it’s time for a new unit.

Your window air conditioner is set to the incorrect setting.

It’s possible that your window air conditioner isn’t chilling for a simple cause. It’s possible that it’s not in Cool mode. Window air conditioners are constructed with numerous settings, each of which serves a specific purpose. Because not every window air conditioner is manufactured the same, the modes available to you may differ. These three settings, however, are found in practically all window air conditioners: Cool Mode, Fan Mode, and Dry Mode.

Here’s a quick rundown of each mode’s functions. Know your modes so you can get the most out of your window air conditioner purchase.

Mode of Cooling

When your air conditioner is set to Cool Mode, it will remove heat from the room until the thermostat temperature is reached. It also dehumidifies the air, making it more comfortable and less “muggy.” Once it achieves your preferred room temperature, it will work to keep it there until you change the mode on the unit or adjust the thermostat to a new temperature.

This is the first item you should examine if your window air conditioner isn’t working. Is your window air conditioner set to cool? If it doesn’t work, try switching to Cool Mode and see what happens. If it’s in Chill Mode and still won’t cool your room, there’s probably something else wrong. And you’ll have to keep looking for the root of the problem.

Mode of the Fan

When your window air conditioner is set to Fan Mode, it works similarly to a standard household fan. The machine does not blow cold air in fan mode; instead, it circulates the air that is already present in the room to maintain adequate air flow. This mode is wonderful for a crisp spring day when the outside air temperature is perfect and you just need a little more air movement inside.

In Dry Mode

This setting is available on most contemporary window air conditioners. It’s also known as Dehumidifier Mode, and its duty is to dry out the air, as you would have guessed! When your window air conditioner is set to Dry Mode, it just removes moisture from the air and does not chill it. This mode is perfect for a hot, humid day when everything seems damp and your primary purpose is to dry things out rather than cool your home.

Your window air conditioner filter is clogged or dirty.

It’s also possible that the back fins are filthy.

The air conditioner filter is something that should be cleaned on a regular basis. If your filter is dirty or clogged, it is likely impeding air movement and preventing your air conditioner from chilling to its full potential. Furthermore, if the filter is too dirty, it may cause frost to build on the evaporator coils, obstructing air movement even more. The best solution is to replace the filter and clean out any debris that has accumulated in the filter area. You can clean the evaporator coils with warm, soapy water if there is any dirt buildup.

If your window air conditioner isn’t chilling properly, make sure to check the filter and the fins/coil in the back

Your window air conditioner is too small for your room.

In terms of the amount of heat they can remove per hour, or, to put it another way, how much cool, dry air they can deliver, not all window air conditioners are created equal. It’s possible that your window air conditioner isn’t working because it’s too tiny for the room.

The cooling power of a window air conditioner is measured in BTUs (British Thermal Units). To chill a square foot of space, most window air conditioners require 20 BTU. For example, if you want to cool a 500-square-foot room with an average ceiling height, you’ll need a 10,000-BTU window air conditioner.

Before you assume your window air conditioner is damaged, make sure you check the BTU rating to see how much cooling power it has! It’s possible that you’re simply utilizing an air conditioner that’s too tiny to adequately cool your home. If this is the case, you may either upgrade and replace your current window air conditioner with one with a larger BTU rating, or you can purchase a second unit to complement your current one.

In either case, it’s a good idea to double-check that your window air conditioner has enough BTUs to chill the area you want it to. This will not only ensure that you have an air conditioner that can truly cool your room. But it will also prevent your window air conditioner from wasting electricity and increasing your bill without efficiently cooling your home.

Is it better to be overly big? No. You don’t want to utilize a window air conditioner that is significantly larger than you require. As a result of this:

  • Cool the room rapidly and turn it off before much moisture has been eliminated. As a result, the room will be chilly and clammy.
  • Burning electricity unnecessarily will raise your monthly bill.

You want to choose the correct size window air conditioner for your home in order to get the coldest air while spending the least amount of money on electricity; not too tiny, not too big!

Use our AC BTU Calculator if you’re having difficulties figuring out what size air conditioner you’ll need for the room you’re trying to cool.

It’s a simple and useful tool for determining whether your window air conditioner is the proper size for the room.

If you decide to purchase a new window air conditioner, make sure to use the Calculator to ensure that you choose one that is the “ideal” size for your room.

Thermistor failure in your window air conditioner

A thermistor is a component found in window air conditioners. It keeps track of the temperature in the area to be cooled and sends signals to the compressor to switch on or off the cold air based on the temperature [for example, in your living room]. The thermistor will send a signal to the compressor to turn off the cool air if it detects that the area has reached the desired temperature.

A properly functioning thermistor will also alert the compressor to resume blasting the cool air if the region is still too hot. A faulty thermistor is one probable cause of your window air conditioner not cooling. To find the thermistor in your window air conditioner, remove the exterior shell and reveal the electrical control board. The thermistor is a little part with a glass bulb on it that you may find once you’ve found the control board. Examine your thermistor for indications of wear and tear, looking for any disconnection or damage in particular.

If your thermistor shows symptoms of wear, it should be replaced. You can install it yourself, but make sure to use a new thermistor that has been certified by the manufacturer of your window air conditioner! Don’t worry if you’d rather leave the air-conditioner dissection to the specialists; they’ll know just how to diagnose and repair your faulty thermistor. Soon, you’ll be able to enjoy the cool air in your home once more!

The Compressor in Your Window Air Conditioner Is Broken

One of the most crucial components of an air conditioner is the compressor. It circulates refrigerant like a pump, capturing heat inside your home and dumping it outside. This allows cold air to flow, and the air conditioner cannot function correctly without a properly operating compressor. If your air conditioner is producing warm air, even in Cool Mode, and the filter and fins are clean. And the unit appears to be in good working order, your compressor may have failed. If your compressor isn’t working, it’s time to think about getting a new window air conditioner.

Is it really necessary to replace the compressor? Most likely not. When a compressor breaks, it’s usually because the air conditioner is old. Because the compressor is a costly component to replace, it is likely more cost-effective to invest in a new window air conditioner rather than a compressor replacement.

When Should You Replace Your Window Air Conditioner? 

Unfortunately, repairing a window air conditioner is more expensive than buying a new one. The majority of repair shops charge between $50 and $75 only to diagnose the issue. Then there’s the component cost. In many circumstances, a bill of $100 to $225 will cover the cost of a replacement window air conditioner.

When people ask us when they should replace their window air conditioner, we usually tell them that the older it is. It makes sense to spend $100 or $150 to fix a room air conditioner that is less than 5 years old. Spending that much on a child above the age of eight does not, in our opinion, make sense. It all relies on your budget and circumstances in the middle. For example, if you live in an apartment but want to move to a home in a year or two. Most likely one with central air conditioning, repairing the unit rather than replacing it is a more cost-effective option.

Hopefully, you were able to figure out why your window air conditioner wasn’t working and fix it.
