If your AC is not cooling properly, there could be a number of reasons for the same. In this post, we’ll explore eight of the most common reasons for why your AC is not cooling properly. From problems with the compressor, gas to dirty coils, we’ll help you troubleshoot the problem so that you can get your AC unit up and running again.
Why is my AC not Cooling?
This is a question Indian people often ask when their AC units are not cooling. While it’s the job best left to the AC technicians to fix, it’s important to understand the reasons for the AC units not cooling properly. Here are eight common reasons Indians face:
- Refrigerant is too much or too less
- Air filter is not clean
- Evaporator coils are clogged
- Fan has some issues
- Coils are frozen
- Refrigerant is leaking
- Compressor is defective
1. Not enough or too much refrigerant
If your AC unit isn’t cooling properly, it could be because there’s not enough or too much refrigerant in the system. This is a common problem in India that can be easily fixed.
If there’s not enough refrigerant, it means that the AC is not blowing cold air and unable to cool the room properly. This can be caused by a leak in the system. To fix this, you’ll need to add more refrigerants to the AC unit.
If there’s too much refrigerant, it means that the AC unit is cooling the air too much. This can be caused by a faulty valve. To fix this, you’ll need to remove some refrigerant from the AC unit.
If you’re not sure how much refrigerant to add or remove, it’s best to call a professional.
2. Dirty air filter
A clogged or dirty air filter will restrict airflow and prevent your AC unit from operating at peak efficiency. As a result, your AC unit won’t be able to cool your home as effectively and your energy bills will go up.
If you think your AC unit’s air filter is dirty, the best thing to do is replace it with a new one. You can find replacement air filters at most home improvement stores. Once you’ve replaced the air filter, your AC unit should be able to cool your Indian home more effectively.
3. Clogged evaporator coils
If your AC isn’t cooling your Indian home despite running constantly, the problem may be with your evaporator coils. These coils play an important role in the cooling process, and when they become clogged, it can prevent your AC from blowing cold air properly.
Fortunately, you can usually clean your evaporator coils yourself with some basic cleaning supplies. However, if the coils are severely clogged or damaged, you may need to replace them. In either case, it’s best to call a professional AC technician in your city in India to diagnose the problem and help you find the best solution.
4. Fan issues
The fan is responsible for circulating cool air throughout the room, so if it’s not working properly, the AC will struggle to cool the space.
There are a few different issues that can prevent the fan from working properly. The first is a blocked fan blade. The blades can become clogged with dust or debris, which will prevent them from moving freely. You can clean the blades with a brush or a vacuum cleaner attachment.
Another issue that can cause the fan to fail is a faulty motor. The motor is what powers the blades, so if it’s not working properly, the blades won’t move. You’ll need to replace the motor if this is the problem.
5. Thermostat problems
In case your AC is not blowing cold air, the first thing you should check is your thermostat. Thermostats are the devices that regulate the temperature in your home, and if they’re not working properly, your AC won’t be able to either. There are a few different things that can go wrong with a thermostat, so it’s important to troubleshoot the problem before you call a professional.
One of the most common thermostat problems is that the batteries are dead. If your thermostat uses batteries, be sure to check them and replace them if necessary.
Another common issue is that the thermostat is not set to “cooling” mode. Double-check the mode and make sure it is set to “cooling.” If neither of these solutions works, you may need to call a professional to help you troubleshoot the issue.
6. Frozen coils
Frozen coils could be a reason for your air conditioner’s failure to cool effectively. This may occur if the appliance is not utilized over an extended length of time, such as throughout the winter. As a result of the coils’ inability to absorb heat when they freeze, the AC unit is unable to cool the air.
If you think your AC unit has frozen coils, the first thing you should do is turn off the unit. Then, check the coils to see if they are frozen. If they are, you will need to thaw them before you can use the AC unit again.
There are a few different ways you can thaw frozen coils. One way is to use a hair dryer on the low setting. Another way is to use a can of compressed air. Once the coils are thawed, you can turn on the AC unit and if it works then great otherwise ring an expert.
7. Refrigerant leaks
A refrigerant leak may be the cause of your AC not blowing cold air. Refrigerant is what helps your AC unit cool the air, so if there’s a leak, the air won’t be as cool as it should be.
There are a few signs that you may have a refrigerant leak, including warm air coming from your AC unit, hissing or bubbling sounds coming from the unit or ice buildup around the unit.
If you think you may have a refrigerant leak, it’s important to have it fixed as soon as possible. A refrigerant leak can cause your AC unit to stop working entirely, so it’s best to address the issue sooner rather than later.
8. Defective compressor
The compressor is responsible for circulating the refrigerant in the system, and if it is not working properly, the AC will not be able to cool your home.
There are a few ways to tell if the compressor is defective. First, check to see if the unit is making any strange noises. If the compressor is damaged, it will usually make a loud, grinding noise. You may also notice that the unit is not cooling as efficiently as it used to or that it is taking longer to cool your home in India.
If you think the compressor is defective, you should call a professional to inspect the unit and make the necessary repairs. Trying to fix the compressor yourself can be dangerous, so it is best to leave it to the experts.
There are a number of reasons why your AC is not blowing cold air or might not be working properly. These include everything from a dirty filter to a problem with the thermostat. In some cases, you might be able to fix the problem yourself. However, in other cases, you might need to call an AC professional.

Frequently Asked Questions
How can you tell if the thermostat is causing your AC to not cool properly?
If the air conditioner runs constantly and short cycles, if the room feels warmer than the temperature you set it to, or if the cooling system fails unexpectedly, the problem may be with the thermostat.
How often should you change your air filters to ensure optimal cooling performance?
It is recommended that you replace air filters every one to three months. However, it is best to change your filters more frequently. You can install a better air filter or change them even more frequently if someone in your family has mild to moderate allergies.
Can a bad fan impact the overall cooling of your AC unit?
The fan is in charge of distributing cool air across the room, so if it isn’t functioning properly, the AC will have a difficult time cooling the area. The fan may not function effectively due to a fan blade that is obstructed or a malfunctioning motor.
