Are you having problems with your air conditioner? Does it keep turning on and off? This problem is also known as short cycling. It refers to a problem where the cooling cycle does not complete and terminates prematurely and it then turns on again.
Keep in mind that when you ignore this problem, it will cost you a lot of money as a lot of power is needed by the AC when it turns on. In addition to higher electricity bills, it will also affect the service life of your air conditioner and you will be forced to spend a lot more money on repairs. Do not make the mistake of ignoring this issue as it could lead to bigger problems and you might need to replace your air conditioning system.
Let’s learn more about the reasons behind the aircon keep turn off.
1. Problem with the thermostat.
The second thing you need to check is the thermostat and you need to make sure that it is functioning properly. If there is a problem with the thermostat, it will fail to read the temperature accurately and that could lead to your air conditioning system starting and stopping frequently. It could be due to low batteries in the thermostat. If the thermostat screen is fading, it could be a problem with the batteries and in such a case, you should immediately replace the batteries of the thermostat. If the problem still persists, it is time to call in a professional technician to figure out the problem and fix it.
2. Bad placement of thermostat
Another problem could be due to the bad placement of the thermostat. If the thermostat is located near a window or it receives direct sunlight, it could be reading the wrong temperature. If the thermostat is placed close to a hot room such as your bathroom or your kitchen, it could be sensing wrong readings. If it is placed directly beneath the air vents and it receives direct airflow, the temperature readings are going to be incorrect and that will lead to issues. If moving the thermostat doesn’t solve your air conditioner problem, call in a professional technician to diagnose and fix the problem.
3. Clogged air filter
One of the most common reasons for inefficient air conditioning systems is the clogging of the air filters. If you have never cleaned or replaced the filters in your air conditioning system, it is time for you to check the filters and replace them in case they are dirty. Dirty air filters are not only a drag on the performance of your air conditioner but are also bad for your health. These dirty filters could also be a reason for short cycling of the air conditioner.
4. Wrong Aircon Capacity
Sometimes, people make the mistake of choosing a capacity that is much higher than required for a particular room. Sometimes, it is due to buyers getting a discount on a bigger capacity AC or for several other reasons. If you have recently installed a new air conditioning system and you are facing this problem, it could be due to the bigger capacity or size of the AC than required. When the system is too big for a space, the refrigerant cycle won’t be able to complete appropriately.
It will cool down the home too quickly and then turn off. The AC will then have to turn on again shortly as the temperature rises. Too much capacity might seem like a good idea but it could lead to problems. You will not only have to pay far higher energy bills than needed but you will also have to spend a lot more money on repairs. Also, the short cycling will reduce the service life of your air conditioner. If you think that this is the problem, call in a professional to get a second opinion on the size of the air-conditioning system.
5. Refrigerant leak
Another reason could be a refrigerant gas leak from the air-conditioning system. One of the most common misconceptions associated with refrigerant gas is that an air conditioner uses it up and you need to top it off regularly. The truth is that refrigerant gas is inside a closed-loop system and if there are no leakages, its level will never go down. However, refrigerant leaks occur as the pipes containing the refrigerant gas get corroded and start developing small leaks.
The refrigerant gas keeps escaping and it leads to performance issues. When the level of refrigerant gas is low, the compressor inside the AC begins to malfunction and shuts down due to low pressure. Once the compressor is turned off, the refrigerant gas pressure will start to build up and the compressor will turn back on and the cycle will keep repeating. In short, it will create short cycling and you are already aware of the problems associated with short cycling.
To conclude, there could be a number of reasons for your air conditioner to turn on and off repeatedly every few minutes. One of the biggest mistakes you could make is to ignore the problem. If you do not get it fixed from a professional AC technician immediately, you might be forced to replace the complete air-conditioning unit. In addition, you will be paying much higher energy bills than expected as the air-conditioner pulls in a lot of power when it starts.
As far as choosing a professional technician for fixing your air conditioner is concerned, it is important that you hire a professional who has a lot of experience in fixing the brand of air-conditioning system you have in your home. Not every technician has experience with all the brands and they might not have the tools or replacement parts required to fix the problem. Therefore, make sure the technician you are planning to hire for fixing the problem has experience in dealing with the brand of AC you have.
