6 Reasons Why Your Air Conditioner Is Not Blowing Cold Air

One of the typical problems with air conditioning systems is not blowing cold air. That is why your aircon could be on but still not cooling the room. But what could be causing your aircon system not to blow cold air? Well, here are 6 possible reasons:

Aircon Cold Air

1. Dirty Condenser Unit

Have you checked your condenser unit? This is the part of the unit that is installed outdoor and that why it is more prone to dirt and debris. The unit also houses the condenser coils that cool off the refrigerant so that it can absorb more heat in the room. If the condenser unit is dirty, then it might be unable to dissipate heat from the refrigerant. Therefore, make sure that you have cleaned the condenser unit, and the aircon will resume normal operation. Regular aircon services can also help deal with the issue.

2. Frozen Coils

Another reason for an air conditioning system not blowing cold air is frozen coils. For the cold air to be blown into the house, the hot air in the room passes over the evaporator cold, and the refrigerant absorbs the heat in it. The fan then blows the cooled air into the room. On the outside, the cold air in the atmosphere will absorb the heat in the refrigerant in the condenser coil. If the two coils are frozen, then air in the room will not come into contact with the refrigerant hence will not be cooled. On the other hand, if the condenser coil does not dissipate heat in the refrigerant due to freezing, the room will not be cooled. For this, hire a specialist to handle deal with defrosting.

3. Inadequate Air Flow In The Vents

You need to check the amount of air flow coming into the room. Depending on the kind of aircon that you are using, you can tell the amount of air flowing by holding the light at the vents’ end. If there is inadequate airflow, it means the amount of cold air coming into the house is little. There are two ways that you can go about it. First, you need to check the condition of the filter. Clogged and dirty filter could be the problem. The solution is to have filters replaced to fix the problem. You should also check the condition of the fans in the evaporator. If the fan is faulty, the amount of air blown into the room is significantly reduced.

4. Check For A Faulty Thermostat

A thermostat is one of the crucial parts of an aircon system. It is a gadget or an electronic device that helps you to set the temperature that you need in the room. If the thermostat is faulty, then you will have a problem of your aircon being unable to cool the room. Sometime, the battery could be the problem so check out it is working condition. If the battery is okay, check the condition of the thermostat. In other cases, the reason for the aircon not blowing cold air could be the thermostat being faulty. Check if the gadget is faulty, and it is, have it fixed or replaced. In addition, ensure regular aircon services to address these issues.

5. Less Refrigerant

The amount of refrigerant could be the reason why your aircon system is not cooling the room effectively. Note that this is the medium that transfers heat from the indoor air to the outdoor air. Therefore, if the refrigerant volume is low, then you will have a problem with cooling the room. The major cause of the low level of aircon refrigerant is leakage. The solution is to fix the leaks as well as refilling the gas to the required volume. That is why we recommend regular aircon services to detect leaks early.

6. Hardware problems

In some cases, the hardware of the aircon could be the problem causing the unit not to blow cold air. Just like the rest of the HVAC appliances, air conditioners are also prone to wear and tear hence affecting the operation of the machine. Check if crucial parts such as the evaporator and condenser coils are in good order. You also need to check the condition of the compressor as well as the refrigerant pipe. Check if all valves are working as well. To avoid hardware issues, carry out aircon services as recommended by a specialist or the manufacturer.

These are some of the main reasons for aircon not blowing cold air into the room. Although you can use DIY tips to fix some of the problems, hire a professional aircon specialist to handle proper aircon services and complex issues such as defrosting.
