Why is my AC running but not cooling? During the hot summer months, one of the most aggravating scenarios that may occur is when your air conditioner is operating, but it is not generating the necessary amount of cool air for you to remain comfortable. This may be an indication of an issue that needs to be addressed, in addition to being a pointless waste of both effort and financial resources. In this post, we will talk about some of the most common reasons why your air conditioner might be operating, but it might not be cooling, as well as what you can do to repair the problem.

Reasons why your AC is running but not cooling

Dirty air filter

A dirty air filter is one of the most common causes for an air conditioning machine to be running but not producing cooling. When an air filter is unclean, it reduces the amount of air that can pass through it, which increases the likelihood that the evaporator coil may freeze and hinder the flow of cool air. In order to avoid this problem altogether during the summer months, it is highly recommended to inspect and maybe change your air filter on a monthly basis or thereabouts.

AC running but not cooling

Low refrigerant levels

Low amounts of refrigerant are another common reason why an air conditioning unit would run but will not cool the air. It is the job of the refrigerant to draw heat from the interior of your home and release it into the surrounding air. If the refrigerant level in your air conditioning unit is low, it will have difficulty removing heat from your home, which will result in warm air being blown out of the vents. If necessary, a qualified HVAC expert can inspect your air conditioning equipment and install more refrigerant on their own. For jb quality air conditioning service for repairs see here.

Thermostat issues

The temperature in your home is regulated by the thermostat you have installed. If it is not functioning properly, it may not be sending the correct signal to your air conditioning unit to switch on or off. This can cause an air conditioning machine to run but not produce any cooling. Make sure that the temperature and mode settings on your thermostat are at the appropriate levels by checking them out.

Clogged condenser unit

It is the job of the condenser unit to discharge the heat that has been absorbed by the refrigerant into the ambient air. It will struggle to transfer heat effectively if it is clogged with debris such as leaves, dirt, or grass clippings, which will cause your air conditioning unit to run but not cool the room properly. This problem can be avoided to some degree with consistent cleaning and maintenance of the condenser unit.

Faulty compressor

Compressing the refrigerant and distributing it throughout the system is the job of the compressor, which serves as the beating heart of your air conditioning machine. If it is not functioning properly, your air conditioning unit will have difficulty providing cool air, which will result in the machine running but not actually cooling the room. Any problems that may arise with the compressor can be diagnosed and fixed by a trained professional technician.

What to do if your AC is running but not cooling

If you find that your air conditioning system is operating, but it is not producing cool air, there are a few things you can try to fix the problem on your own before contacting a qualified HVAC contractor. First things first, you should examine the condition of your air filter and replace it if it is dirty. Second, check the settings on your thermostat to make sure they are in the correct position. Third, be sure to inspect your condenser unit for any dirt or dust and clean it if it turns out to be dirty. It is suggested that you hire a professional technician to diagnose and fix any problems with your air conditioning machine if these measures do not address the issue.


During the hot summer months, having a problem with an air conditioning unit that is running but not chilling may be both aggravating and uncomfortable. To our relief, this problem can be traced back to a number of common factors, all of which may be remedied by doing routine maintenance and cleaning. In the event that you are unable to handle the issue on your own, it is recommended that you call a professional expert to diagnose and repair any difficulties that may be occuring with your air conditioning unit. You can avoid feeling hot and uncomfortable during the entire summer if you take prompt action to address these conditions.
