If your AC is running constantly, even after you turn it off, it can mean different things. It can be a thermostat setting problem, the condenser coils might be dirty, or you might need a bigger unit.
An AC that will not turn off, especially in extreme temperatures, can be very worrying. But do not sell the house and move to the beach just yet; we are here to help you figure it all out. Follow this guide as we give you some ideas of what the problem might be and how to fix it.
Why Is My AC Running Constantly?
There are a few reasons why your AC keeps running, such as thermostat settings, outside temperature, undersized unit, low refrigerant or dirty condenser coils. Some problems are easier than others to fix, so before you call a professional, take a look at what you can try by yourself.
5 Common Solutions For A Constantly Running AC
Sometimes, a simple switch on the thermostat or closing the curtains can do the trick to make your AC take a break from running nonstop – or at least buy you some time until a proper inspection. As a homeowner, it is important to know how to troubleshoot your air conditioner. However, if it is a stubborn unit, you might need to call a professional after all.
1. Thermostat
If your system is set to ON, try to change it instead to AUTO. If the thermostat is damaged or malfunctioning, your AC unit might get stuck running continuously. While this issue is typically inexpensive to fix, it is important to address it promptly to prevent more serious damage.
2. Outside Temperature
If your AC fan is constantly running, it might be because you have set your thermostat to a specific temperature, and it is trying its best to reach this temperature despite outside changes.
If there is direct sunlight hitting the AC, or if it is a hotter part of the day like midday, the AC will not stop working until it reaches the designated temperature, so try adjusting it.
3. Undersized Unit
If the AC is too small for the space, maybe it is running constantly to keep up with the area. You may need to change the unit completely or add another one to help out.
4. Refrigerant Levels
If the refrigerant is at a low level or if there are AC refrigerant leaks, the AC might not be able to reach the temperature you set it to. So check the levels to make sure they are ok. Otherwise, you will probably need a professional to fill them up.
5. Dirty Condenser Coils
If the coils are dirty, the AC might not be able to remove the heat from the air properly. It is usually located outside and you can clean it gently with water by using a garden hose or a bucket.
By following these steps, you can troubleshoot why your AC will not stop running. However, if these solutions do not work, it is best to contact homeyou HVAC professionals to diagnose and fix any deeper problems. Good luck!
