Window air conditioner stops cooling after while?
- Dirty air filter
- Low refrigerant levels
- Faulty compressor
- Dirty condenser coils
- Electrical issues, such as faulty wiring or a malfunctioning thermostat.
Window air conditioners are a convenient and cost-effective way to cool a room or small space. However, when these units stop cooling properly, it can be frustrating and uncomfortable, especially during the hot summer months. If you’re experiencing this issue with your window air conditioner, it’s important to address it promptly to ensure your comfort and prevent further damage to the unit.
In this article, we’ll explore the possible causes of a window air conditioner not cooling properly after running for a while, signs to look out for, and solutions to the problem. By understanding the issue and taking appropriate measures, you can ensure that your window air conditioner is working efficiently and keeping you cool when you need it most.
Causes of Window Air Conditioner Stopping to Cool
There are several factors that can cause a window air conditioner to stop cooling properly after running for a while. Some common causes include:
- Dirty Air Filter: A dirty air filter can restrict the flow of air into the unit, causing it to work harder to cool the air. Over time, this can lead to reduced cooling efficiency and potentially damage the unit.
- Low Refrigerant Levels: Refrigerant is the substance that cools the air in an air conditioning unit. If the refrigerant levels are low, the unit won’t be able to cool the air effectively.
- Faulty Compressor: The compressor is responsible for circulating refrigerant through the unit. If it is not functioning properly, the unit may not cool properly.
- Dirty Condenser Coils: Condenser coils are responsible for releasing heat from the unit. If they become dirty or clogged, they won’t be able to release heat effectively, leading to reduced cooling efficiency.
- Electrical Issues: Faulty wiring or a malfunctioning thermostat can also cause a window air conditioner to stop cooling properly.
By understanding these common causes, you can take appropriate steps to address the issue and ensure that your window air conditioner is working efficiently.
Signs of a Window Air Conditioner Not Cooling Properly
If your window air conditioner is not cooling properly, there are several signs you may notice:
- Warm Air Blowing from Unit: If the air blowing from the unit is not cool, it may indicate that the unit is not functioning properly.
- Weak Airflow: If the airflow from the unit is weak, it may be a sign that the unit is struggling to cool the air.
- Unit Running Constantly: If the unit is running constantly, it may be a sign that it is unable to maintain the desired temperature.
- Unusual Sounds or Smells: If you hear unusual sounds or notice unusual smells coming from the unit, it may be a sign that there is a problem that needs to be addressed.
If you notice any of these signs, it’s important to take action promptly to prevent further damage to the unit and ensure your comfort.
Solutions to Window Air Conditioner Not Cooling Properly
If your window air conditioner is not cooling properly, there are several solutions you can try:
- Clean or Replace the Air Filter: If the air filter is dirty, clean or replace it to improve airflow and allow the unit to cool the air more efficiently.
- Check Refrigerant Levels: If the refrigerant levels are low, a professional technician will need to add more refrigerant to the unit.
- Clean the Condenser Coils: If the condenser coils are dirty or clogged, clean them to improve the release of heat from the unit and allow for more efficient cooling.
- Check the Compressor: If the compressor is faulty, it may need to be repaired or replaced by a professional technician.
- Check Electrical Components: If the issue is with the wiring or thermostat, a professional technician will need to diagnose and repair the issue.
By taking these steps, you can address the issue and ensure that your window air conditioner is functioning properly. It’s important to keep up with regular maintenance to prevent future issues and extend the life of your unit.
Preventing Window Air Conditioner Issues
Regular maintenance and proper usage can help prevent issues with your window air conditioner. Here are some tips to keep your unit running smoothly:
- Clean or Replace Air Filter Regularly: Cleaning or replacing the air filter every few months can improve airflow and prevent the unit from overworking.
- Keep Condenser Coils Clean: Regularly clean the condenser coils to improve heat release and prevent reduced cooling efficiency.
- Use the Unit Properly: Avoid running the unit with doors or windows open, as this can make the unit work harder and reduce its efficiency. Also, avoid setting the thermostat too low, as this can cause the unit to overwork.
- Schedule Professional Maintenance: Schedule regular maintenance with a professional technician to ensure that the unit is functioning properly and catch any issues before they become bigger problems.
By following these tips, you can prevent issues with your window air conditioner and keep it running efficiently for years to come.

Why is my window air conditioner making a loud noise?
There are several possible causes of a loud noise from a window air conditioner, including a loose or damaged fan blade, a dirty or clogged condenser coil, or a faulty compressor. It’s best to have a professional technician diagnose and repair the issue.
How often should I clean the air filter on my window air conditioner?
It’s recommended to clean or replace the air filter on your window air conditioner every 1-3 months, depending on usage and the environment. A dirty air filter can reduce airflow and cooling efficiency.
How do I know if my window air conditioner needs more refrigerant?
If your window air conditioner is not cooling properly and the air coming from the unit is not cold, it may need more refrigerant. A professional technician can check the refrigerant levels and add more if necessary.
Can I install a window air conditioner myself?
While it’s possible to install a window air conditioner yourself, it’s recommended to have a professional technician do the installation to ensure proper placement and secure installation. Improper installation can lead to inefficiency and damage to the unit.
Why is my window air conditioner freezing up?
A window air conditioner may freeze up if there is a lack of airflow over the evaporator coil, a dirty air filter, or low refrigerant levels. It’s best to have a professional technician diagnose and repair the issue to prevent further damage to the unit.
