What To Do if Your Air Conditioner Not Blowing Cold Air

What To Do if Your Air Conditioner Not Blowing Cold Air 06 Feb

Are you experiencing problems with your Air Conditioner? Is your air conditioner not blowing cold air but running? Well, when the cooling system of your AC unit suddenly stops working, the reason usually is a tripped circuit breaker, blown fuse, or the usual wear and tear.

This situation is quite frustrating, mostly if it happens during the summer. While a professional technician can fix some AC issues, there are also many situations where a homeowner can repair it.

To help you fix your broken air conditioner and save you from further expenses, we identify the causes and provide solutions to help you with your problem.

There are several reasons why your air conditioner is not blowing cold air. Some of the culprits of this issue are the following.

  • Power Issues
  • Incorrect Thermostat Settings
  • Clogged Air Filter
  • Refrigerant leaks
  • The size of the air conditioner is not appropriate to the room

Plug-in the AC or Check the Electrical Panel

Don’t get mad right away if your air conditioner is not blowing cold air. It might be a fundamental problem such as no electricity, not plugged into the socket correctly, or issues in the electrical panel. If there are no power problems in your area, then maybe your AC is not plugged in correctly. If it does, then the problem is the electrical panel.

Air conditioners consume a large amount of energy, and it might have tripped the breaker or blown a fuse. If you use many AC at home, make sure to upgrade your electrical panel. It is also vital to check built-in switches as they might be overloaded.

Correct the Thermostat Settings

If you are lucky enough, your AC might not be broken at all. Instead, the thermostat is probably in the wrong settings, has issues, or in heating mode. If this is the case, adjust the settings or only “On” the cooling mode.

If it is already “On,” your compressor and refrigerant are probably not running, which means that the blowing fan is only spinning and moving air. What you should do instead is to change the setting into auto mode. This setting will only turn on the fun when the cooling system is not working.

Replace or Clean the Air Filter

The AC’s air filter is probably blocked and needs a replacement. The air filter is responsible for protecting the sensitive parts of the unit from dust and dirt. Hence, clogs are realistic situations. When the filter clogs, the airflow is restricted, which you might feel that it is not cooling at all.

Don’t let the filter clog for too long. It can break your air conditioner unit and increase your electricity bills. What you need to do is to replace the air filter with a new one. Ideally, air filters need to be replaced from 1 to 3 months of use.

If you just replaced the filter, it is easily clogged with dust, dirt, and debris. As such, the coils may freeze, and the frost will prevent the airflow. Instead of replacing your air filter, you need to clean them with mild soap, water, and a soft brush.

Check the Refrigerant

The refrigerant is an essential component in the cooling system. Whether your AC uses a ductless system or a central one, both need a refrigerant to operate. Without a functioning refrigerant, heat will occur, and cooling would not be possible. A refrigerant leak is the most common reason for the loss of refrigerant. Therefore, it would be best if you prevent leaks from happening.

Leaks will start small and will gradually increase. It can cause a lot of AC problems such as:

  • Heat not absorbed because of frozen coils
  • Inconsistency of the cooling system
  • System breakdown caused by the failure in the compressor

Your refrigerant may not be in good condition if the following situations exist:

  • AC unit is already ten years and above
  • Recurring problems of the system unit
  • Unexplainable repair costs

Install a proper AC unit for the room

The cooling system is not the problem but the size of the AC installed in your room. If a small-sized AC is installed in the living room, then the size is the issue. A small AC installed in a bigger space will work harder to do its job yet can lead to system breakdown.

The same goes for big-sized AC installed in smaller spaces. It will undergo an on and off-cycle, affecting the efficiency of the unit. For this reason, you need to make sure the proper size of the AC unit is installed in the place.

However, if you think that size of the AC is not the problem, check the vent of your AC. The vents should be open to making sure that the cooling system is working properly. Even if one of the vents is closed, a cold room would not be realized. With the closed vent, heat in the room will mix in the cold air. Hence, cooling would not be possible.

Conclusion

Everyone will agree that some of the worst feelings are when the air conditioner is not blowing cold air, especially during the sweltering summer heat. This situation happens but it’s preventable when you have a professional technician who visits your home for inspection and AC maintenance.

With an on-call technician, you are assured that your AC units will provide you service for many years. It will also give you peace of mind knowing that no malfunctions will happen in the middle of the night or during heat season.
