When your air conditioning system keeps running and never seems to shut off, the problem could be linked to a number of malfunctioning components – frozen evaporator coils, a clogged air filter, a bad electrical relay switch that needs to be replaced, the fan blowing constantly, dirty condenser coils, a bad thermostat, …
Why is my AC compressor constantly running?
One of the most common reasons an air conditioner runs constantly is restricted airflow. Your AC needs a certain amount of airflow in order to supply your home with cool air. If something is blocking the airflow to your AC, your system will run longer in an effort to bring in a sufficient amount of air.
How do I fix my AC that won’t turn off?

Why is my AC still on after I turn it off?
If your air conditioner keeps running when it’s turned off this could be a sign of shorted thermostat wiring. A continuously running air conditioner could also be triggered based on the settings selected for the unit.
How long should AC compressor stay off between cycles?
Between 7 and 10 minutes
Quality of your Air Conditioning Unit
Fortunately, most of the modern units work efficiently, so you will not have problems with long and short cycles. So, how long should AC stay off between cycles? Between 7 and 10 minutes after every cycle is ideal.
How long can AC compressor runs continuously?
There is no such thing as the appliance will melt, or get damaged if run continuously for 24 hours. In fact, you can run your AC constantly for an entire week. I have tried running my Hitachi inverter split AC continuously without turning it OFF for an entire week.
How long does AC compressor stay on?
However, your air conditioning system should for cycles of 15 minutes or more. When you notice cooling cycles shorter than this, something may be wrong. The AC’s compressor shouldn’t run for less than 10 minutes and then turn back on a short time later and repeat the process.
Should I turn off my AC if it is not cooling?
So, if your air conditioner isn’t cooling, and you suspect a refrigerant leak, or if you’ve checked the air filter and thermostat to no avail, yes, you should shut your air conditioner off and call us right away.
How do I turn off my AC compressor?
Quote from the video:
Quote from Youtube video: The first thing you need to do is turn the switch to the off. Position. Now if you're finished for the day you can go ahead and unplug your air compressor.
Is it OK for home AC to run all day?
The constant running of your AC unit will reduce pressure in the evaporator, or cooling coil until it freezes over, according to Cool Today. This is why in some cases, this constant running can be dangerous. The freezing of the coil can cause liquid refrigerant to flood back into the unit’s compressor and damage it.
Is my AC compressor supposed to turn on and off?
Low Refrigerant
You may know it by its brand name of Freon®. When your refrigerant is low, the needed compressor-pressure levels are affected. This triggers your compressor’s low pressure control, shutting off your compressor. When the pressure rises and triggers your AC to restart, this causes the short cycling.
Why does my AC turn on every 5 minutes?
An AC system may turn on and off repeatedly due to dirty, broken, or failing parts or for various other mechanical or electrical reasons. The term short cycling refers to when an AC system’s cooling cycle terminates prematurely only to turn on again after a short time.
Can a compressor runs continuously?
Only those air compressors with a 100% duty cycle can run constantly at the specified pressure and flow. Running an air compressor beyond its duty cycle limit leads to premature wear and tear, higher maintenance costs and, at its most extreme, breakdowns which can shut down production.
How many hours can a compressor run?
Depending on the size and type of compressor, air compressors can be left running anywhere from a few hours to 24 hours a day, seven days a week.
Can air compressor run 24 hours?
Rotary screw and vane compressors are specifically designed for 100 percent duty cycle. If your operation needs it, they can run 24/7, but like a piston unit they run when a pressure signal turns them on. Unlike most piston compressors, most rotary compressors idle before they shut down completely.
What happens if you leave an air compressor on all night?
If there are no production activities during these hours, the air compressor(s) will continue to feed leaks and other miscellaneous loads, such as air consuming equipment left on, or air dryer purge. Depending on how many cubic feet per minute these consume, the compressor operating costs can be significant.
