AC Short Cycling in NJ? Why It Turns On and Off Constantly

Short cycling is when the AC starts, runs for a few minutes, then shuts off and repeats. It is common in North NJ during the first heat wave and it drives up electric bills fast.

Why short cycling happens

• Oversized AC system
• Dirty air filter or clogged coil
• Low refrigerant
• Thermostat placement in direct sun
• Faulty capacitor or contactor

Quick checks

• Replace the air filter
• Make sure the thermostat is not near a vent or window
• Confirm vents are open and unobstructed

If short cycling continues, stop running the system and call a pro.

When to call Air2Cool

• The system cycles every few minutes
