Short Answer
Central air conditioners are complex systems, so there can be a variety of reasons why it may not be cooling effectively.
Common problems include a dirty or blocked air filter, a clogged condensate drain, a frozen evaporator coil, low levels of refrigerant, or a malfunctioning fan motor.
If the system is not cooling, it is best to contact a licensed HVAC technician to diagnose and repair the problem.
Common Reasons Central Air Conditioner May Not Be Cooling
When your central air conditioner isnt cooling, it can be a major inconvenience.
Fortunately, there are a few common reasons why a central air conditioner may not be working properly, and its usually an easy fix.
One of the most common reasons a central air conditioner isnt cooling is because of an issue with the compressor.
The compressor is an important part of the air conditioning system that helps to cool air by compressing and circulating the refrigerant.
If the compressor is damaged, it can prevent the air conditioner from cooling properly.
Another common issue is a problem with the fan.
The fan is responsible for pushing the air through the system and out into your home.
If the fan is not working properly, it wont be able to circulate the air efficiently, which can lead to a decrease in air flow and reduce the cooling power of the system.
The thermostat can also be a cause of your air conditioner not cooling.
If the thermostat is set too low, it can prevent the air conditioner from cooling properly.
Additionally, if the thermostat is not set correctly, it can prevent the air conditioner from cycling on and off correctly.
The condenser is another component of the central air conditioner that can cause problems.
The condenser is responsible for releasing the heat from the air in your home.
If the condenser is dirty or clogged with debris, it wont be able to perform its job properly, which can result in a decrease in cooling power.
Finally, the refrigerant can also be a cause of your air conditioner not cooling.
Refrigerant helps to cool the air by transferring heat from inside your home to the outside.
If the refrigerant is low, it can prevent the air conditioner from cooling properly.
If your central air conditioner isnt cooling, it could be caused by any of these issues.
Fortunately, a qualified technician can help diagnose the problem and determine the best course of action to get your air conditioner up and running again.
What to Look Out For When Troubleshooting

To check if the compressor is working properly, turn off the breaker and listen for the sound of the compressor running.
If it is not running, the compressor may need to be replaced.
The fan can also be a cause of cooling issues.
If the fan is not running at the proper speed, it can cause the air conditioner to not cool correctly.
To check the fan, turn off the breaker and listen for the sound of the fan running.
If the fan is not running, it may need to be replaced.
The condenser can also be a source of cooling issues.
If the condenser is dirty or blocked, it can cause the air conditioner to not cool correctly.
To check the condenser, turn off the breaker and inspect the condenser for any dirt or debris that may be blocking it.
If the condenser is blocked, it should be cleaned or replaced.
Finally, the refrigerant can be a cause of cooling issues.
If the refrigerant levels are low, it can cause the air conditioner to not cool correctly.
To check the refrigerant levels, a qualified technician should be contacted to inspect the system and determine if the refrigerant needs to be topped off or replaced.
These are the most common causes of central air conditioners not cooling correctly.
If these issues are not present, a qualified technician should be contacted to help diagnose the problem and determine the best course of action to get the air conditioner up and running again.

You should also make sure that all of the filters are clean, as dirty filters can cause the air conditioner to run inefficiently and may lead to overheating.
If your central air conditioner is still not cooling after resetting it, the issue may be more serious and require the attention of a professional.
A qualified technician can help diagnose the problem and determine the best course of action to get your air conditioner up and running again.
When to Call a Professional
If your central air conditioner is not cooling, it may be time to call in a professional.
A qualified technician can help diagnose the problem and determine the best course of action to get your air conditioner up and running again.
There are several different things that can cause a central air conditioner to not cool, including issues with the compressor, fan, thermostat, condenser, and refrigerant.
A technician will have the knowledge and experience to determine the root cause of the problem and offer the best solution.
Before calling a professional, it is a good idea to check your air filter.
