Air Conditioner Constantly Running: Why an AC Unit Won’t Turn Off

In the scorching heat of December to February, imagining a life without air conditioners is most unpleasant. That’s why a majority of people prefer to keep them turned on throughout the day. Sometimes it happens that our air conditioner doesn’t turn off as it should and keeps on running. If you are facing any such issue, then no need to worry. This article will help you to determine the root cause of these issues and how to resolve the problem quickly.

Before going into one-by-one factors, there’re a few common reasons that can potentially cause this issue. In the burning heat of summer, your air conditioner might need to overwork to maintain the internal temperature that you set; that’s why it may keep on running without any rest. If this isn’t the issue, check these factors along with their solutions to enjoy relief from whopping electricity bills.

1) Malfunctioning of Thermostat

If your air conditioner keeps on running, then a faulty thermostat can be the reason behind it. The malfunctioning of the thermostat can be noticed by the difference in the internal temperature of the room and the temperature set on the thermostat. A faulty thermostat can’t accurately track the room temperature. So, this keeps your AC always running.

The only way to prevent such issues is to replace your thermostat immediately. It’s always preferable to hire a professional for installing and calibrating the thermostat.

2) Issues with Relay Switch

Relays serve for the opening and closing of electric circuits that pass through the air conditioner. With time, these switches start malfunctioning, resulting in faulty communication between the fan and thermostat. So, when you opt for turning off your air conditioner, then the fan might keep on working. It’s highly undesirable to handle this issue by yourself. As it’s a technical problem, calling a professional will be the optimal choice.

3) Fan Setting

If your AC is constantly running, then consider checking your fan setting. In some cases, when the fan is left turned on, then even after turning the air conditioner off, the fan keeps on running. In order to avoid this issue, you need to set your fan setting to Auto. So, next time you turn off your AC, the fan will also shut down.

If you are unsure about this issue, then check your thermostat and look for the fan setting. If it’s already on Auto, then pay heed to other issues as this function is properly working.

4) Dirty Condenser Coils

Coils serve to remove the heat from the system to the outside environment. But if by any means, these condenser coils become filled with dust and dirt, then the air conditioner needs to overwork to maintain the required temperatures. Dust stops or hinders the flow of air between the system and the environment. So, the AC keeps on running until it reaches the required temperature set on the thermostat, but due to clogged coils, it becomes harder to achieve. That’s why dirty condenser coils can also be the reason behind the constant working of your AC. It’s recommended to clean these coils on a regular basis for enhanced efficiency and saving on electricity bills.

The Bottom Line

Constant running of your AC consumes more energy, thus increasing the energy bills. So, it’s a cost-saving option to diagnose the issue and rectify it sooner rather than later. For technical issues, it’s strongly recommended to call expert technicians to avoid further damage. Quick Air is offering same day repair and maintenance service in all the major cities of Australia.
