The Most Common Reasons For AC Not Cooling

Reasons For AC, not cooling can be various. It can be a real downer if you come home after a long day in the sun during summer, only to discover that your Air Conditioner is not working. Now, as you start to ‘curse’ the sun and the heat or even your ‘life,’ you need to ‘cool down. Maybe it is not such a serious problem after all. Before you get dialling your electrician’s number and spend a ‘bomb’ for fixing the problem, stop and think. What if you could do it yourself? And save yourself from future disasters and having your pockets burned for no reason whatsoever. So, what are the reasons for the Air Conditioner not working? Some are so basic that they are almost laughable. Let us explore a bit:

Reasons for AC not cooling

Most of the time, the Filters of the Air Conditioner are the reason for your Air Conditioner not working. This is obvious because your filter does the hard work of ‘stopping’ the dirt, dust, particles from entering your system. As the debris enters the filters, over time, it can clog and block the airflow. Hence, there is a reduced airflow in the process. In severe cases, big clogs can even lead to the complete shut down of the Air Conditioners. 

 What You Can Do?:

The issue can be easily resolved by cleaning the filters regularly. Keep a check on the filters at least monthly and replace them if necessary. It is that simple. And you thought you’d have to get a new Air Conditioner altogether? 

2. All Coiled Up

The Condenser Coil is an important part of the Air Conditioner. Sometimes, the problem lies within the coils. As this is an outdoor component of the appliance, it is regularly subjected to environmental factors like Grime, dirt, and dust. These tend to accumulate within the coil fins, thus, clogging them. 

 What You Can Do?:

The function of the Condenser unit is to dissipate heat; being a heavy task, the Coils must remain clean and free from debris. For the ‘free-flow of the heat, it is necessary to remove any clogs in the coils. So, simply check the Coils before you jump into a decision to switch to another Air Conditioner altogether.

3. Not ‘Cool’ Enough

Refrigerant or the ‘Coolant’ circulates through the evaporator coils, hence, lowering the temperatures in the process. The refrigerant is also responsible for keeping the heat from the exterior sources away, thus contributing to the overall cooling effects indoors. Sometimes the problem is as simple as your AC running out of enough amount of refrigerant. 

What You Can Do?:

Here, you simply need to replace enough amount of refrigerant into the Air Conditioner Unit. However, for this, you do require professional assistance; but it is not as big a problem as ‘tearing your Air Conditioner apart’ unnecessarily or non-required replacements. 

4. The Lazy Compressor

The Compressor of an Air Conditioner is responsible for compressing the refrigerant and ensuring it circulates throughout the Evaporator and the Condenser Coils. However, sometimes the Compressor turns ‘lazy’ and weak. This way, the Cooling cycle is not initiated, and the coolant is not pumped throughout the system. 

What You Can Do?:

Well, this needs replacement and also professional assistance for the same. Get hold of your ‘electrician guy.’ 

5. Thermostat Of The Problem

The Thermostat of the Air Conditioner is responsible to detect the temperature change and initiating the cooling cycle. Hence, if you are experiencing that the Air conditioner is switched on and yet not cooling the room, well, the thermostat is at fault. Sometimes, you can also detect this problem as you notice that the thermostat’s display is blank or not ‘lighting-up.’ This could be a simple case of battery failure. 

What You Can Do?:

 As stated, you simply need to get hold of a new set of batteries for your thermostat and replace them. And that is about it.

6. The Wrong Settings

The Air Conditioner is indeed responsible for the automatic cooling of the room. But, even the machine requires the ‘human touch’ at times. If you notice that your Air Conditioner is not cooling enough despite being in good working conditions, then check your settings. 

 What You Can Do?:

The solution to this problem is quite simple. You simply need to change the settings. Ensure that the Thermostat setting is on the ‘Auto Mode’ if it is in the ON mode. Also, check for the other Pre-set options like Constant fan, heat, and more.

7. The Broken Circuit

If you have been experiencing lowered cooling effects in your Air Conditioner, you might want to check your Circuit Breaker. It could be because the unit might be tripping the Circuit breaker. This results in warm air being blown into your room through the indoor unit. 

What You Can Do?:

 For this, first, you need to take a look at the breaker box and check if the outdoor unit has tripped. If it is the case, try and switch it on. If it trips yet again, do not reset it. Get some professional help; this problem can be easily resolved for the same.

8. The Size ‘Matters’

You have got the perfect Air Conditioner design, the brand is excellent, and it was within your budget. But it still does not cools enough. Well, you simply got the wrong size. Yes, you need the right size and capacity to be able to cool your room and home ‘just right.

What You Can Do?:

It is simple to calculate the size of your Air Conditioner according to the room size. If you are still confused, you simply ask the right sources or do your research. But, it is never a good idea to buy an AC according to your budget and not the size. 

9. The Atmosphere

Your Air Conditioner cools your space, but that does not mean that it does not require some amount of cooling itself. To make sure your Air Conditioner works efficiently, you need to make sure it is fixed at a place that is away from direct sunlight and where the surrounding temperatures are generally ‘cool.’ 

 What You Can Do?:

When installing the Air Conditioner, make sure you select a place that does not face the sun or the heat. This helps assist the energy efficiency of the device and also offers better functioning. 

10. The ‘Remote’ Problem

You have checked the Condenser, the Evaporator, the Compressor, and all the other parts of the Air Conditioner. They all seem to be just fine. Also, the circuits are intact, and your AC is fixed at a place that is cool and dry. So what could be the problem? Maybe it is the Remote Control.

What You Can Do?:

 Sometimes, it is not even the Air Conditioner Unit itself. Take a thorough check of your remote control and find out if it is working well. Bring it closer to the Air Conditioner Unit and try working it out. Are the Settings fine? Is the Polarity alright? Well, then, are the batteries working fine? If all is well, you simply need to get a new remote control. 

The Conclusion

Why my AC is not cooling?  Do not jump to conclusions by yourself. Most of the time, we are ‘conned’ by so-called professionals into spending needlessly. This leads us to regret buying the Air Conditioner altogether and often we believe that it is a major problem. Try and educate yourself with the basics and simple working of the Air Conditioner. Learning about its parts and how they are meant to function can go a long way in ensuring better efficiency. So, before you dial up a professional, give your device a look-over by yourself. Maybe you could end up being the ‘next handyman’ star of your family?
