Most of the Time, Aim for A 15 Minute Cycle Ideally, your AC should run for 15 minutes on nice, warm days. Only on those rare triple-digit temperature days should your air conditioner be running almost all the time.
Why is my car AC going on and off?
Intermittent cooling is often caused by the components of your vehicle’s AC system freezing up. Typically an iced over evaporator is the culprit. An evaporator covered in ice can’t cool the air, so you would have to wait until the ice melts, which is why the cold air eventually returns.
Why does my AC turn on and off every 5 minutes?
A dirty air filter could be what’s causing your AC to short cycle. Here’s why: When an air filter gets too dirty, it restricts airflow into your air conditioner. Without enough warm air being pulled into your system, your evaporator coils can freeze over, which would cause your AC to short cycle.
Why does my AC keep short cycling?
Frozen evaporator coils are a common cause of short cycling. Sometimes, air conditioners freeze up when they’re running while it’s too cold outside, usually at night. In other cases, freezing may be caused by a dirty filter or a mechanical problem. Shut your system down, allow it to thaw completely, then run it again.
Can a bad thermostat cause short cycling?
A broken or poorly placed thermostat can cause short cycling. A thermostat positioned near a heat source or in direct sunlight can warm too quickly, signaling your furnace to shut off before the entire home is adequately warmed. … This sometimes causes short cycling, depending on your temperature setting.
Why would a compressor short cycle?
Short cycling occurs in your compressor when a mechanical failure is causing the run times to terminate prematurely and since set point has not been achieved, it restarts shortly afterward, thus requiring more compressor ‘ON’ time to compensate.
Is it normal for car AC compressor to cycle on and off?
It is natural for your car A/C compressor to cycle on and off. If it is doing so rapidly, though, it can indicate an improper charge (such as being low on R-134a refrigerant). Once the air conditioning system is properly charged, it should no longer be a problem.

Why does my AC cut on and off?
You may have a dirty air filter problem. When the air filter restricts airflow, the evaporator coil can become frozen, causing the unit to turn on and off. As a reminder, air filters should be replaced at least once a month. You may do this more often if you are constantly running your air in the summer.
What is considered short cycling?
Short cycling is an HVAC term used to define a situation where a furnace or air conditioner turns on and off too frequently.
