Are you having trouble with your air conditioner not blowing cold air? What can you do? In most cases, this is not a problem with the unit itself but rather a lack of efficiency. This post will show you how to fix this problem and allow your home or office to cool down again.


Check the AC unit to make sure it's not running on low refrigerant

The first thing to check is whether or not your AC unit is running on low refrigerant. This can happen if you have a leak somewhere in the tubing or if there's something obstructing one of the valves.


If there isn't enough refrigerant in your system, then this could be why there's no cold air blowing out of your vents--and fixing this problem will require either buying more or having someone come out and fix whatever issue caused them not to be able to get enough coolant into their systems.


If you're not sure if you have enough refrigerant, then it's best to call an A/C service professional for help. They can come out and inspect your system and tell you exactly what needs to be done.


Look for debris in the condenser, which is part of the system that pushes air through the vents

If your AC isn't blowing cold air, it's a good idea to do a visual inspection of the condenser. The condenser is part of your system that pushes air through your vents. It has a fan and coils that are located outside, but if there is debris in or around these components, it could be blocking their ability to push cool air into your home.


If you see any debris in or around the coils, it's a good idea to clean them off. You can do this with a soft brush that has stiff bristles or by spraying water on them. If there is more than just dirt and dust on your system, then it may be time for an A/C service professional to come out and give you an estimate on what needs to be done.


If you have a coil unit, check your airflow.

If you have a central air conditioning unit, check the airflow. Make sure there is no duct tape or string blocking it. If your AC is blowing warm air from the vents and not cold air, this could be why. 


You can also check to see if there's dirt accumulating around your coil unit or in any other part of the system where air passes through before reaching its destination--this can affect how well it works as well!


Check your filters and replace them if necessary.

If your filter is dirty or clogged, it may be the reason why your AC isn't blowing cold air. Dirty filters can cause a restriction in the airflow. To check if this is the case, remove the filter and inspect it for dirt. If there's a lot of dust buildup on the filter surface, consider replacing it with another one made specifically for your unit.


If there isn't much visible dirt on your current disposable filter but you still suspect that something might be wrong with it (such as a tear), feel free to clean off as much dust as possible before putting it back into place. You can use compressed air or vacuum cleaner attachments if necessary!


Check your thermostat settings.

Check your thermostat settings. Does it need to be turned up or down? Or changed from cooling to heating?


If the problem is with your thermostat, try adjusting the temperature up or down and see if that helps. If you're having trouble getting the right temperature, check out our guide on how to set a thermostat for more information about how to use them properly.
