Why Does My A/C System Keep Turning Off?

Why Does My A/C System Keep Turning Off?

As another scorching summer fast approaches, the state of your air conditioner is more important than ever. You turn it on to get some relief only to find that it shuts off in a matter of minutes. Your house definitely isn't cool enough, so what could be the reason?

If your system turns off and back on again at frequent intervals, this is called "short-cycling."

Frozen Evaporator Coil

An air filter laden with dirt and debris blocks your system's air flow. This blockage can lead to frozen evaporator coils.

Air conditioners use refrigerant to cool hot air from the outdoors; when air is unable to move effectively, the refrigerant doesn't move fast enough and the coil freezes over, causing the system to turn off.

Refrigerant Leak

A coolant called "Freon" is required to make your A/C work. When there's a leak, or you simply don't have enough fluid, pressure levels are thrown off balance and the A/C's compressor unit cannot operate normally.

An air conditioner compressor is the most vital part of your system, and when it doesn't have enough refrigerant to transfer, it will shut off. A professional HVAC technician can easily check your system's refrigerant levels and locate any leaks that are causing your system to stop working.

Your System is Too Big

If you've always had this problem with your air conditioner or recently upgraded your system, it's possible that the unit is too big for your home. A large A/C unit will cool your home too quickly, causing it to shut off before your house has actually been thoroughly cooled.
