4 Possible Reasons Your Air Conditioner Is Not Blowing Cold Air

4 Possible Reasons Your Air Conditioner Is Not Blowing Cold Air

If your air conditioner is running but not blowing cold air, it is an indicator that something is wrong with one of its components. Summertime makes you rely heavily on your cooling system. When there is no cool air coming out of your unit, the situation can be frustrating. Calling a repair technician to fix the problem is the best solution to consider. But first, you need to know the reasons your unit is not cooling you down.

Issues with thermostat

When your air conditioner is not working, you should always check the thermostat first. If the unit is set to an incorrect temperature, you will not be able to get your unit to engage. Your thermostat should be set to at least 5 degrees below room temperature for it to blow cold air. You should also check that the thermostat is not set on the heat function or turned off.

For thermostats that are set to “auto” setting, there are instances when your unit blows room temperature air. This happens because it is part of the auto cycle. You will need to switch the setting to on instead of auto for the unit to blow cold air again. Thermostats may fail to work if they are running on batteries. Change batteries to find out if it will solve the problem or check the wiring if the unit is wired.

Clogged outdoor unit

Your air conditioning system will also blow warm or hot air if you have a clogged-up outside unit. During the air conditioning cycle, your unit will pump refrigerant, converting hot air to cold air. Throughout the process, hot air needs a place to escape. This is the primary function of your outdoor unit.

Leaves, debris, ice snow, dirt, and sticks can block the vents of your outdoor unit. The blockage makes it difficult for the hot air to escape. Since it takes another path, you will experience the hot air in your living room.

Blocked vents

Your vents also need an inspection if you only get little air or no air from your unit at all. Check your vents if they are clogged with debris or dirt. If the vents are clear, you need to check your air filter as well. Filters need to be changed 3 to 4 months and more frequent if you have pets. If you have not cleaned your air filter for so long, this could be the reason there is no cool air coming out of it.

Even a dirty filter can affect the efficiency of the entire system. If you still encounter the same problem even after changing or cleaning the filters, you will need to call an HVAC repair technician. Poor airflow might be due to a severe problem. A professional repair technician can spot the source of the problem and provide solutions to it.

Failed fan motor

Your outdoor unit is also composed of a fan motor, which produces inconsistent noises when it is not working correctly. Be sure that the fan of your outdoor unit is operating. Something is also wrong with your fan if your compressor fan does not produce a strong whirr. There are even cases when you smell burnt rubber, and the unit will shut off completely. You will need to call a repair technician to address the problem. It is difficult for the compressor to circulate if the fan is not working correctly.

Leaky Refrigerant

Refrigerant leaks can also cause your compressor to stop working. If your unit is low on refrigerant, the compressor will not also function correctly. You will get warm air as a result. It is essential for your refrigerant to maintain its constant level. If your unit leaks, the refrigerant will become low. Calling a repair technician to repair the unit and charge the system is the best thing to do. If you are going to fix refrigerant leaks yourself, you will do more harm than good to your unit.

Finding out what is going on when there is little or no air coming through the vents of your air conditioning is the first step you have to take. It is difficult to identify the source of the issue if you do not call a repair technician to have your unit inspected. For minor problems, DIY repair may be a breeze, but you should entrust mechanical or electrical issues to Air Conditioning Repair Rockwall experts.
