If your air conditioner is not blowing cold air, there could be a few reasons. This blog post will discuss some of the most common reasons why your AC might not be cooling your home properly. We will also provide some tips on how to fix the issue yourself and when it is time to call in a professional technician.
5 most common reasons why an air conditioner might not be blowing cold air
The air filter is dirty and needs to be cleaned
Over time, dust, dirt, and other airborne particles can accumulate on the filter, restricting airflow and making it harder for the unit to cool the room. In some cases, the filter may even become completely clogged, preventing any air from passing through at all. If you suspect that your air conditioner’s performance is suffering due to a dirty filter, be sure to check and clean it as soon as possible.
The evaporator coils are frozen and need to be thawed out.
Your air conditioner may not be blowing cold air because the evaporator coils are frozen. When this happens, it prevents the coils from absorbing heat, which is how they cool the air. The first step to thawing out the coils is to turn off the air conditioner and fan.
Next, check the coils to see if there is ice build-up. Use a hairdryer on the low setting to thaw the ice. Once the coils are thawed, you can turn on the air conditioner and fan and see if the problem has been resolved. If not, you may need to call a professional for further assistance.
There are low refrigerant levels in the AC unit.
When an AC unit is properly charged with refrigerant, it will cool the air as it blows over the evaporator coils. If there is not enough refrigerant in the system, the coils will not be able to lower the temperature of the air, causing it to blow warm air.
In some cases, low refrigerant levels can be caused by a leak in the AC unit. If you think this may be the case, it’s best to call a professional for help. Otherwise, you may end up damaging your AC unit beyond repair.
The condenser coils are dirty and need to be cleaned.
A crucial part of an air conditioner is the condenser coils. These coils help to remove heat from the air, and they need to be kept clean for the air conditioner to work properly. Over time, the coils can become clogged with dust and debris, which reduces their ability to remove heat.
As a result, the air conditioner will not be able to cool the room as effectively. In some cases, the coils may need to be replaced if they are too damaged. However, simply cleaning the coils regularly can often be enough to keep them working properly.
There is an issue with the blower motor or fan.
If the motor is burned out, it won’t be able to spin the fan. If the fan isn’t spinning, it won’t be able to circulate the air. You’ll need to have the motor or fan replaced in either case.
Another possibility is that the fan belt has come off or needs to be tightened. A loose fan belt can slip and prevent the fan from spinning. If the fan belt is completely broken, it will need to be replaced.
In some cases, the fan blades are dirty or obstructed, reducing airflow. If you suspect a problem with the blower motor or fan, it’s best to call a technician for assistance.
How To Fix An Air Conditioner That Is Not Cooling Properly
Now that we’ve gone over some of the most common reasons why an air conditioner might not be blowing cold air let’s talk about how to fix the issue. In some cases, you may be able to fix the problem yourself. However, it may be best to call a professional for assistance in other cases.
If your air conditioner’s filter is dirty, the first step is to clean or replace it. If the evaporator coils are frozen, you’ll need to thaw them out before turning on the unit. In some cases, low refrigerant levels can be fixed by recharging the AC unit.
However, if there is a leak, it’s best to call a professional for help. Dirty condenser coils can often be cleaned with a brush or hose. If the blades on the fan are dirty, you can use a cloth to wipe them down. Finally, if there is an issue with the blower motor or fan, it’s best to call a technician for assistance.
When It Is Time To Call In A Professional Technician
There are some cases where it is best to call a professional aircond service technician for help. If you suspect that there is a leak in your AC unit, it’s important to call a professional right away. Trying to fix a refrigerant leak yourself can be dangerous and may cause further damage to your AC unit.
Similarly, if you think there might be an issue with the electrical components of your AC unit, it’s best to call a technician rather than try to fix the problem yourself. Electrical issues can be very dangerous and should always be handled by a professional.
In general, if you’re not sure what the problem is or how to fix it, it’s always best to call a technician for assistance.
