7 Reasons Why Your Air Conditioner Is Not Cooling Your Home

Is your air conditioner not cooling your home? You may wonder why your air conditioner is running, but not cooling your house. When this is happening, it’s a sign that there is something wrong with your aircon.

Sometimes, your air conditioner may need cleaning, and other times there are parts that need to be repaired or replaced. In this blog, we will explore some possible reasons why your air conditioner at home is not cooling properly.

Reasons Why Your Air Conditioner Is Not

When your air conditioner is turned on but is not blowing cool air, this shows that there’s a problem. Your air conditioner not cooling properly can be due to various reasons. Here are some possible reasons why your aircon is not cooling your home:

1. Dirty Air Filter

One possible reason why your air conditioner is not cooling your home is because of the air filter. It can be the result of a filter not being cleaned.

Your air conditioner cannot cool properly if the air filters are clogged by dust, dirt, or debris. When they are clogged, this restricts airflow, which would then result in your air conditioner not cooling the inside of your home properly.

Additionally, remember that the air filters are responsible for filtering the air going in and out of your space. So, a dirty or clogged filter can result in various issues.

To avoid your air conditioner not cooling properly and other issues, you should make sure to clean your filter regularly. You should also change the air filter when needed. Ideally, you should check your air filters every month.

2. A Faulty Thermostat

Another reason why your aircon is not cooling could be because of a faulty thermostat. The problem could be with the thermostat. For instance, the thermostat could be set incorrectly. Make sure to set it to cool. If your air conditioner still won’t cool, it can be because of a dirty air filter (as discussed above).

Additionally, there could be a problem with the wiring or batteries. You may need to replace your thermostat’s batteries when required. Some thermostats can also benefit from a hard restart: remove the thermostat from its power source and then return it. At times, thermostats can fail, so it may be time for a replacement.

Remember that when there’s a problem with your thermostat, it can affect the overall function of your AC. No cool air can be because of a thermostat, so make sure to check it.

3. A Refrigerant Leak

A refrigerant leak can be another reason why your aircon is not cooling properly. Refrigerant is a chemical that’s important to the cooling process. Its main function is to absorb the heat inside your home and release it outside, which would then cool down your home.

If your system has a refrigerant leak, it will not be able to properly move the heat out of your home. When there is a refrigerant leak in the system, it’s important to seek professional AC services as soon as possible. A technician will be able to spot issues and do the necessary repairs.

4. Frozen Evaporator Coil

The evaporator coil can also have issues, and these issues can be the reason why your aircon is not cooling your home properly. Over time, coils can get dirty. There can be mold and mildew buildup, and this can negatively impact their functioning. Additionally, evaporator coils can also freeze, and a frozen evaporator coil can lead to inadequate cooling.

When your evaporator coil is frozen, you should contact an HVAC professional as soon as possible. Additionally, it’s important to note that dirty air filters can also cause the evaporator coil to freeze. So, make sure to give the filters a thorough clean and replace them if necessary.

5. Problems with the Condenser Unit

If your air conditioner is not cooling properly, it can be because of problems with the condenser unit. Condenser units are located outdoors, and they can be blocked by plants, bushes, or other things. If the unit is blocked, it will not be able to release heat properly from the condenser coils.

So, the heat that is removed from your home will not be released properly. Your air conditioner may run, but it’s not going to function efficiently. If you have issues with your condenser unit, it is better to let the professionals handle them.

6. Problems with the Compressor

The compressor can be the reason why your aircon is not blowing cool air. The compressor is responsible for controlling the flow of refrigerant in the system. Without the compressor, the system will not be able to absorb heat from your home and transfer it outside.

If there are problems with the compressor, like if it starts to malfunction or gets damaged, your whole system will not be able to cool your home adequately. If there is a problem with the compressor, it is better to contact a professional.

7. Poor Maintenance

Now, one reason why your air conditioner is not cooling is because of poor AC maintenance. While you may keep many parts of your AC clean, you still need to have your AC professionally serviced regularly. To prolong the use of your unit, it is better to schedule regular AC maintenance services and not wait until something goes wrong.

Regular AC maintenance services will help avoid problems before your unit becomes beyond repair. A technician will be able to identify potential problems and address them before they become bigger. So that your aircon can cool properly, you should opt for proper maintenance with a professional.

Why Professional AC Maintenance Services Are Important

When your aircon is not cooling properly, this may be because of mechanical problems, which can be solved by experienced technicians. Proper maintenance of your AC is not just about your comfort; it’s also about prolonging the life of your unit. Professionals know how to clean your unit the right way and make all the necessary repairs.

You should schedule at least two AC maintenance services annually along with 3 routine check-ups or cleaning. This way, your air conditioning unit can function properly and blow cool air.
